Hakoniwa Shared Map S Settings

Game Overview

Hakoniwa Shared Map S is a game of nation building, trade, diplomacy and land and naval warfare on a shared 90×90 hex map. The standard update interval is 12 hours. Each nation can queue up to 50 plans.

A season lasts at most 360 turns. From turn 100, before the turn limit, an unaffiliated nation wins by owning 60% of all land, or a faction wins by owning 70% with every member having belonged for at least 14 turns. Such a victory ends the season immediately. At the turn limit, nations are ranked by a weighted total of their shares of territory, population and treasury among living nations; all nations tied for first place win. Turn-limit scoring: territory 60%, population 25%, treasury 15%. From the next season, economic assets (treasury and private cash and goods valued at common world prices, averaged over the latest 12 turns) replace the treasury. Economic assets recorded from season turn 26 (earlier turns are not counted).

Statistics offers five History charts: Population + troops / Population / Troops / Area / National power. History is kept for the latest 120 turns. Troops include reserves and deployed or embarked troops, excluding wounded troops. National power uses the national score (P). Lines break at unrecorded observations.

Countries can be removed from charts only after turn 35. On turns 36–69, an extinct nation is excluded if it is absent (counted as zero) in every record from turn 35 through the current turn; from turn 70 onward, the same check uses the latest 35 turns. A reappearance or missing record keeps the nation on the chart. Existing nations remain visible even with zero Troops or National power.

Founded

Choose from the suitable sites on the founding screen. The center must be Wasteland or Forest; it and all six adjacent cells must be unused Wasteland, Plains or Forest. Mountain, Sea and Shoal are excluded regardless of resources. Suitability is checked again when founding is executed. Nearby land, Forest, mineral deposits, water and spacing from existing sites also affect site selection.

The center starts as a capital with population 60 (6,000 people). Adjacent cells receive two Towns of population 20 each, a Farm of size 10 and one Supply Depot; the remaining adjacent cells retain their natural terrain under your ownership. Initial Funds: 6000 ×100M JPY; Food: 3000 (100 t units); reserves: 200 (100 people units). Initial stocks of the eight resources are listed below.

Resource-bearing mountains overlay iron, stone, coal, surface-deposit or U markers on the mountain image. Oil-bearing sea, shoal and waste cells display an oil marker. Undeveloped natural resources generate neither income nor extraction reserves. Use Build Mine / Oilfield to develop the matching facility before extraction. A land oilfield is drawn over waste. Sites without a resource attribute or occupied by foreign troops cannot be developed.

In public views such as Sightseeing, Missile Bases, Defense Facilities and Supply Depots appear as Forest, while Undersea Bases appear as Sea.

Land reclamation is unavailable.

Tunnel (command 5, cost 900) can be built on your own mountain after the neutral-land share unlocks at 5% or less. At least two adjacent mountains without tunnels are required. Infantry, Artillery, Marines and Airborne move one cell, and Armor moves two. Mountain Troops move the same with or without a tunnel. Territorial and war restrictions apply as for normal movement. Tunnels survive ownership changes and enemy troops can use them. Resources, timber and combat retain mountain rules; the tunnel disappears when the terrain ceases to be a mountain.

Neighboring territory: when clearing, reclamation, digging or construction (including supply bases) checks whether a cell borders your territory, only your own land and port cells count. Sea cells holding your merchant ships or warships do not count. Only offshore deposits (candidate oil seas) can be developed when your own ship of any type is adjacent.

Mountains without deposits produce wood every 4 turns, yielding 1 unit(s).

A Town becomes a Metropolis at 20,000 people. Population caps are 25,000 people for a Metropolis, 25,000 for a New Town, 30,000 for a Modern City and 15,000 for an Undersea City.

Power plants: command 133 builds one on owned plains for 300 Funds or upgrades it for 150 Funds in one turn. Each plant can reach level 10. Each level adds 4% to national industrial output, capped at 80%. Each level consumes 1 Fuel per turn; a shortage scales down the bonus. Generation capacity shown in the country status is the level sum times 40 thousand kW.

Command List

Total: 86 commands. A zero-turn command advances to the next plan in the same turn. Costs shown are base values; see each section for costs by quantity, ship type, terrain and trading terms. Early-game price changes apply during the first 100 turns.

Resources, Units and Base Prices

Units: Funds 1 = 100M JPY; population and troops 1 = 100 people; Food 1 = 100 t; area in Hex. Base prices are in 100M JPY per displayed resource unit.

After rations, treasury Food above 18 times that turn's domestic production spoils by 0.5% each turn, rounded down to whole units (0% disables spoilage), while civilian stock is excluded.

Resource quantities do not represent equal weights across resources. Production technology levels 0–5 multiply finished mining, timber and factory quantities by 100 + 3 × level percent (103% at level 1, 115% at level 5), rounded down once to whole output units. Small quantities can stay unchanged; output beyond the stock cap is lost. Deposits, natural recovery, factory inputs, prices and cash income do not receive the multiplier.

Geological survey 109: 100 Funds and 1 turn. Waste can reveal an oil deposit. Discovery chance is normally 10%; within 2 hexes of sea or shoal it is 20%. A mountain survey still costs the stated Funds and turn but reveals nothing; surveys do not reveal outcrops. A discovered deposit has richness 500. Requires owned or adjacent neutral land without enemy troops, a known deposit or a facility. A miss allows another attempt. Quantity and target are 0. Construction 14 is charged separately.

An offshore deposit can be developed beside any own ship or own cell, including a built offshore oilfield, so oilfields can be chained farther offshore.

Industry policy: command 132 Quantity 0 selects light, 1 heavy, and 2 advanced. Changing costs 25 Funds and takes effect next turn. Heavy unlocks at Production Research 1; advanced at 3. Countries that existed before industry policy start advanced; newly founded countries and countries in a new season start light.

Light industry: 2 Food to 1 Good, factory capacity 50%, industrial Fuel rate 45%.

Heavy industry: 2 Steel to 1 Good and 1 Ammunition, factory capacity 75%, industrial Fuel rate 150%.

Advanced industry: 2 Ore to 1 Good, factory capacity 100%, industrial Fuel rate 75%. Refinery and Munitions Factory inputs do not change with policy.

AI economy planning: estimated agriculture, industry, commerce and power-plant Fuel demand is kept for 4 turns. A power plant is expanded only when industrial facilities total at least 4 levels, incoming Fuel covers demand, and the national output bonus has room. A country in advanced industry considers another mode only after 3 consecutive turns without Ore intake and with another material available. Changes are at least 8 turns apart. The mine / urgent Fuel / power / policy priorities are 78 / 84 / 66 / 74. Heavy factories add Steel to the reserve. AI does not reassign workers by sector share.

CPU resource development: the rule AI and the AI stand-in for LLM nations build mines on public deposits in their own cells and in unowned cells touching their territory. Even with enough stock, when 1000 Funds remain after the cost, workers for one more level (1,000 people) remain after farms and current mines, and miners stay within 50% of the workers outside farms, it considers a new mine or raising a staffed Mine or Oilfield at priority 70 (once every 3 turns, new deposits first, and without waiting on a turn that would otherwise do nothing; Uranium only after the research). When a resource is short, a second facility is considered beside extraction. When expanding into neutral land, a cell next to a land deposit not yet touching its territory scores 16 points higher, and one two cells away 8 points higher (offshore Oil is not counted). A CPU nation whose food exceeds 30 turns of consumption adds no farms and creates mine jobs for people without work. Human nations are unchanged.

CPU nations' worker order: while food exceeds 30 turns of what the population and troops eat, rule-AI nations and LLM nations whose plan the AI filled this turn staff mines and factories (including Refineries and Munitions Factories) before farms and townspeople's farming. Farming gets the people left over. At 30 turns or less, farms and townspeople's farming come first again as before. The order is decided once per nation at the start of each turn. Human nations are unchanged.

CPU instead of doing nothing: on a turn when the rule AI or the AI stand-in for LLM nations has no other turn-using command and would do nothing (raise funds), it picks one of the following in this order if it can pay (after the idle-turn resource development): expand into unowned land (the usual pacing and priority conditions are relaxed for that turn) → take a neighbouring nation's Plains, Farm, Factory or Wasteland with a build, extension or levelling command, not by war (highest value after taking first; never from camp, friendship-treaty, trade-alliance or coalition partners or friendly nations, and never a cell with visible troops or a Wasteland with a deposit) → prepare a naval port, a ship and troops, and send troops by ship to unowned land across the sea → with fewer than 2 ports, build a port on its own Plains next to sea or shallows (at least 3 cells from its current ports) → turn unguarded border Plains into forest, lowest value first. Only when none is possible does it raise funds. Human nations are unchanged.

CPU border watch: every turn the rule AI and the AI stand-in for LLM nations count their cells that a neighbour can take with a development command (Plains, Farm, Factory and Wasteland; forests, towns, mines, ports and the like cannot be taken) and place troops on them, starting with higher-level factories and farms, cells near the capital and cells near land taken last turn (target score base 40). Troops on such a cell stay there; when troops are short, it prepares a supply base and a unit. During a war or war preparation, the existing military decisions come first. On a cell touching a neighbouring nation it does not level or clear land into Plains or build a Farm or Factory unless its troops stand there (except the first port and factory and food emergencies). Plains taken from a neighbour become forest.

CPU peacetime minimum defence: while it has no declared war, the rule AI and the AI stand-in for LLM nations keep, for each border with a neighbour's land (except camp and friendship-treaty partners and nations that count it as friendly), within 2 cells of the border cells at least 1 units with a total strength of at least 50 (100 = 10,000 people), and separately a strength of at least 50 within 2 cells of the capital. Starting with the most valuable border that lacks troops, it places a unit on a supply base near the most valuable takeable cell, builds a base on nearby plains if there is none, and drafts from a large town within the current rules when reserves are short (priority 90: before resource development and the like, after food emergencies). Counted units stay where they are. Once war is declared on it, the war preparation takes over.

Reserve aid: even in worlds with diplomacy, Reserve Aid (command 50) can be sent to an ally in your camp whose land borders yours (it arrives at once; up to 20000 people per command, once per turn). A distant ally in your camp can receive reserves aboard your warship through diplomatic aid (123). Nations outside your camp cannot receive reserve aid. A rule-AI nation sends reserves to such an ally that has been declared upon (including the 5 turns before the war starts) or is at war. It sends nothing while it is itself declared upon (including before the war starts) or under visible threat, but it does send during a war it joined itself; it keeps its reserve floor, the missing part of its capital guard and another 10000 people, sends at most 50% of the rest, and never lets its reserves plus troops fall below 30000 people. Placed troops are not moved.

Ships for reserve aid: when a rule-AI nation wants to send reserves to a distant ally in its camp but lacks the naval port or warships to carry them, it builds what is missing: a naval port if it has none, then destroyers until it has one more warship than it keeps for home defence, one per turn and only on water connected to the open sea. It builds nothing when it would send no reserves (while it is itself declared upon or under visible threat, or has no reserves to spare), when money or materials are short, when its ships are at the limit, or when there is no water beside the ally’s port or naval port where a ship can stop and that is connected to the open sea. If the water beside the port is a dead-end inlet with a one-cell entrance, the ship still enters when that cell is free, loads or unloads, and leaves the way it came (also when loading at its own naval port; it waits if another ship is there). While the ally is under attack, these ships are built even below the steel or industrial goods reserve. A new destroyer carries reserves only after repairs lift it above half strength. While the ally still has a landing site for a supply outpost (such as unowned Plains), building the land route comes first: the ship carrying marines is never used for the aid, and the aid uses a ship only when one is free beyond the home keep and the marine ship. If it lacks warships to carry marines, it builds the naval port and destroyers up to the same number. If it has no Plains for the supply base that forms the marines, it first levels its own Wasteland or Forest and builds there (never mountains, mines or cells with troops). With no Wasteland or Forest either, a nation that has 5 or more town and city cells levels its least populated town other than the capital. The ship sent to pick up troops is the nearest one. For marines it picks the shore nearest the troops that the ship can reach by sea, and both the ship and the troops head there to meet.

Reserve aid to a distant camp ally (123) is loaded onto your warship beside your naval port and unloaded beside the ally’s port. One ship carries up to 20000 people. If it sinks, 30% return to the sender and the rest are lost. For goods aid, an idle private merchant ship within 6 sea cells of the sending port can also be hired. Calling it costs an extra 5 money per sea cell.

Steel economy: Iron Mines and Large Mines yield Steel directly (multiplier 50); Surface Deposits yield Ore, meaning rare earth metals (multiplier 50). An own Coal Mine in any of the six adjacent hexes adds 50% to Steel output. A Munitions Factory uses 1 Industrial Good and 2 Steel for 6 Ammunition. Warships use the same quantity of Steel instead of Industrial Goods, and wrecks return 20% of build Steel. The private Steel holding floor is 32; world buying covers actual consumption only. AI retains 3/6 turns of munitions input and, with a Naval Port, at least 10 Steel for the next hull (reference amount 13).

Industrial fuel: agriculture 45%, advanced industry 75%, commerce 30%. Convert finished output to Funds at fixed base prices, take that share, then divide by the Fuel base price of 17 Funds to debit the national treasury (Food base price: 1 Funds). A shortage scales output and commercial receipts by the available share. Use is zero on the first turn this system runs and reaches full rate on turn 10. At that start, human countries alone receive a one-time grant for 20 full-rate turns, capped at treasury storage, and neutral mountains receive small coal deposits once, with base placement chance 8% times the coal climate-belt multiplier and richness 30.

Sector efficiency: each non-overlapping staffed share p uses f(p)=p×sqrt(1.5−p²). The 100% baselines are agriculture 73%, industry 26% and commerce 0%. Efficiency is 100+35×(f(p)−f(baseline))/f(√0.75) percent, with a 90% floor. It separately scales Food, factory output and commercial sales; production research is independent.

Household Industrial Goods demand: one unit per 500 population units (each unit is 100 residents), with a prosperity factor of treasury Funds divided by population and 1, capped between zero and one, giving up to +100%. The larger of this demand and physical market capacity is multiplied by commerce efficiency and limited by private stock. Treasury Funds indicate prosperity but are not debited. Food and Fuel demand and world purchases are determined separately.

Uranium mine Fuel: production research level 3 unlocks extraction at 5 times the coal-mine yield multiplier. Each extraction produces at most 100 Fuel. Before unlocking, the mine retains its reserve and uses no workers or output.

Mines and oilfields have levels 1–10. Command 128 raises one level for 100 Funds per current level, 10 Stone and 10 Timber. Reserve cap = 10 × level × facility scale; recovery each turn = ceil(level/4) × facility scale (large mines use scale 2). Each staffed mine has one cave-in roll per turn: 11% at level 1, 2% at level 10, linearly interpolated between. A cave-in lowers the level by one (minimum 1) and removes reserves above the new cap. Deposit richness supplies the initial reserve on construction and never runs out. Set both endpoint rates to 0 to disable cave-ins.

Markets, Demand, Ports, Tariffs and Bilateral Contracts

Governments set port access, tariffs and transit fees. Private operators decide trade and transport.

Handling per turn: regular port 256, large port 2048 containers (loading and unloading combined). Scale 2 or higher is large. Each port holds up to 16777215 bonded containers across all owners, with no resource restriction. The transit fee is charged on deposit. Cargo still passes when the receiving treasury is full: the sender pays normally, and the excess disappears. Overflow stays in the original stock or ship; unfinished handling continues next turn.

Private relay trade (new bonded deposits) is paused. Cargo already deposited continues through delivery, takeover or return.

Treasury world purchases of ammunition are capped at 4 per turn in peace and 12 during active war. The price remains 1.25 times the market price; fuel and industrial goods retain their usual caps.

Neutral bank

The bank belongs to no country and creates no new money. It lends only cash deposited by private sectors; total loan principal is limited to 50% of deposit principal. Cash on hand, deposit principal (a withdrawal claim), and loan claims are separate. Interest is 1% of principal per turn, with a 20-turn term. For interest, one turn means one month, or about 12% per year. Unpaid debt is repaid with available goods. Delivering goods does not increase bank cash.

Half of interest actually collected in cash is distributed in proportion to deposit principal; the other half stays as bank reserves. Insufficient reserves stop dividends without reducing deposit principal. Withdrawals are paid in order within available cash; the unpaid part waits for cash from repayments or deposits. Starting 12 turns after a country is first detected as gone, its debt is written off only within reserves; any shortfall remains recorded. At the start of a turn, a private sector below working cash withdraws its own deposit first, then borrows only the remaining shortfall. After private shipping, shipbuilding and domestic trade, it automatically deposits only cash above the cap at turn end.

Interest 1% per turn; 50% of cash interest collected is distributed. Loan ceiling 50%, term 20 turns, disappearance wait 12 turns.

Automatic deposit cash cap 10000 in 100 million yen. Working cash is the sum of private purchases and shipbuilding payments in the preceding four turns, with a floor of 2000 in 100 million yen. Goods lot size 1, goods order Food, Timber, Stone, Ore, Oil, Fuel, Industrial Goods, Ammunition, Steel. Interest is simple; interest fractions below 0.001 (in 100 million yen) carry forward, and dividend fractions are rounded down.

A loan is limited to the smallest of the working-cash shortfall, household sales in the most recent 10 turns, 50% of the value of privately owned stock (including warehouses and cargo in transit), available bank cash, and the bank-wide lending cap. Food uses its fixed price; other goods use world prices. A due-date cash shortfall blocks new loans for the following 12 turns. Automatic private borrowing is checked against these conditions.

Deposits and withdrawals (command 114) and borrowing and repayment (command 115) are handled automatically by the private sector; nations cannot operate them. The private sector withdraws or borrows when needed at turn start, deposits surplus cash at turn end, and repays when due. The finance panel shows the current balances.

Corps, Fleets, Unit Types, Ammunition and Fuel

Corps: 32 (IDs 0–31); Fleets: 16 (IDs 0–15). Each Corps has its own name, color, direction and orders.

Unit abilities and movement

• Occupation: 0 cannot occupy, 1 occupies weakly, 2 occupies. A unit on another nation's land (not Sea or Shoal) lowers that hex's resistance every turn and takes the hex for its nation when it reaches 0 (faster with more troops, and 2 is faster than 1). On its own land it restores resistance.
• Artillery: 0 attacks adjacent hexes only. 1 and 2 can also attack hexes two away; 1 receives no counterattack when attacking two hexes away, and 2 never receives a counterattack.
• ZOC: a unit next to an enemy unit that exerts ZOC cannot move to a hex that is also next to that enemy (types that ignore ZOC and units carrying the ZOC Bypass Cloak are exempt).
• Move between non-own hexes: a type marked No cannot move from a hex its nation does not own to another hex its nation does not own. If either hex is sea-type (Sea, Undersea Base, or a terrain listed below as the same as Sea), every type may move.
• Type change on reinforcement: for a type marked No, placing an additional unit on it only reinforces it and the unit type does not change.
• Movement: 0 cannot enter, 1 moves one hex, 2 moves up to two hexes. Units may board their own nation's ships. A unit carrying the Waterwalking Boots can enter Sea and Undersea Base.

Unit matchups (row: attacking type; column: target type; 10 is standard, higher deals more damage)

Terrain effects (share of damage the row type takes while in a hex of the column terrain; 10 is standard, lower takes less damage)

Terrains not in the tables above use the same movement and terrain effect values as these terrains.

• Same as Sea: Shoal, Offshore Oilfield, Undersea City, Destroyer, Cruiser, Battleship, Aircraft Carrier, Submarine, Freighter, Pirate Ship, Cruise Ship, Breakwater, Sea Mine
• Same as Mountain: Mine, Quarry, Coal Mine, Surface Deposit, Uranium Mine, Large Mine
• Same as Plains: Reserved Land, Port, Lighthouse
• Same as Town Types: Market, New Town, Modern City, Metropolis
• Same as Farm: Large Farm
• Same as Factory: Refinery, Munitions Factory, Large Factory, Warehouse, Power Plant
• Same as Missile Base: Naval Port

Attack and counterattack

Attack damage = (troops + random 0 to experience−1) ÷ 10 × (matchup + unit level × 5) ÷ 10 × support × (target terrain effect − defense) ÷ 10 × receiving unit fixed climate factor × attacking unit weather factor × one quarter if short of Ammunition × attacking country military technology factor

Fractions are dropped along the way. The result is at least 1 and never more than the target's troops. Defense is 1 when the target corps has the Defend order, otherwise 0. If the target carries the Weakness Shield, a matchup above 10 counts as 10. Carrying the War God's Sword doubles the damage, and a target carrying the Ironwall Shield halves it.

Support = (100 + 30 × count) ÷ 100. The count is the number of own units in the adjacent hexes checked before the target is found (the checking order changes every turn, so it is anywhere from 0 to the number of adjacent own units). Types with the artillery attribute check up to two hexes away and use (100 + 15 × count) ÷ 100.

Counterattack damage = (remaining troops + random 0 to experience−1) ÷ 20 × (matchup + unit level × 5) ÷ 10 × attacker terrain effect ÷ 10 × receiving unit fixed climate factor × counterattacking unit weather factor × one quarter if short of Ammunition × counterattacking country military technology factor

A counterattack happens only if the target survives. There is none against artillery attribute 2, or against artillery attribute 1 attacking from two hexes away. A retreating unit counterattacks for 1. Items work the same way as in an attack.

Ammunition is consumed in land combat, naval combat and missile attacks. Normal missiles use 1, anti-personnel missiles 2, and ballistic missiles 4 plus 3 Fuel. Each naval attack uses: Destroyer 1, Cruiser 1, Battleship 2, Aircraft Carrier 3, Submarine 1. Land combat continues without enough Ammunition, with damage reduced to one quarter. Naval attacks stop without enough Ammunition; missiles stop without their required Ammunition or Fuel. Naval gun costs and Ammunition consumption are separate.

Missiles, disasters, new-nation limits, aid and turn prizes

Missile base experience, range and shots

Range is the farthest number of hexes from the base to the target, and shots is how many missiles one base fires per order. Ballistic missiles get 5 more range. Experience is capped at 200. The order is canceled when no base has the target in range.

Thunder at the aimed tile adds 1 to missile scatter radius. When the increase is 1, radii 0, 1 and 2 become 1, 2 and 3, with candidate counts 1, 7 and 19 becoming 7, 19 and 37. PP counts the center twice. The expanded candidates use the same friendly-country check, with the same scope and exceptions, before Funds or ammunition are spent. Neither the launch base nor the actual impact determines thunder; naval gunfire is unaffected.

Disaster rates

Capital hexes are not hit by natural disasters (combat damage still applies). When the world's land, including land nobody owns, exceeds the safety limit of 716 hexes, meteorites and huge meteorites become more likely and land reclamation stops. A tsunami happens only after an earthquake or eruption at sea.

A fire does not destroy a town; it lowers the population instead. Villages, Towns, Cities and Metropolises lose 50%, New Towns and Modern Cities lose 30%, and at least 100 people remain. Troops in the hex are not reduced. A Metropolis that falls below 20,000 people becomes an ordinary town again (Village, Town or City). Factories, Large Factories and Warehouses still become Wasteland after a fire.

New-nation limits and war declarations

For 15 turns after a nation is founded, it cannot declare war, propose friendship or a ceasefire (also when the other nation is that new), cede territory, send aid or launch missiles. For 30 turns it cannot self-destruct a defense facility. A declared war begins 5 turns later.

Aid limits

Territory cession is limited to 10 hexes per turn.

Turn prize

A turn prize is awarded every 25 turns.

Ship Types and Performance

Ship type 0 is a Naval Port. Types 7 and 8 cannot be built by nations. Neutral ships such as Pirate Ships appear under separate rules. See naval combat for performance and actual attack targets.

Hull damage in the ship table is a base value. Military technology levels 0–5 multiply numerical damage on a hit by 100 + 3 × level percent, rounded down to whole damage units. Base damage 1 stays 1 even at level 5; no remainder is saved. Mine and fuel shortage damage, the three hit facility rule, town population loss of 10%, and one step of farm or factory scale are unchanged.

The settings table shows base values; an owner sees base / national effective values. Shipping technology levels 0–5 multiply speed and capacity by 100 + 3 × level percent, rounded down to integers separately. Shipping technology does not change diplomatic transport capacity.

Warships (types 1–5) gain +1 experience per effective hit and an additional +2 per sinking or monster kill (once each; experience cap 255). At experience 10 and 30, maximum HP rises by +1 and +2 (HP cap 15). Promotion does not heal current HP, and supply shortages never lower the level. Repair and supply recover up to the increased maximum. Hardened hits give no experience; mine clearance gives +0. Freighter cargo and pirate loot are not experience.

Sight is the distance at which you can detect warships; Range is the distance at which a ship can attack. Both use hexes, and the Range column shows 0 for types that cannot fire. Sight ranges are Naval Port 3 / Destroyer 2 / Cruiser 2 / Battleship 3 / Aircraft Carrier 4 / Submarine 2 / Freighter 2. Freighters provide sight but do not attack.

Foreign warships (Destroyers, Cruisers, Battleships, Aircraft Carriers and Submarines) outside your nation’s sight appear as Sea. Their nationality, HP, Fleet and embarked troops are also hidden. Submerged Submarines follow the same rule. Your own warships remain visible. Freighters, Pirate Ships and Cruise Ships are always visible, including their nationality, regardless of sight range.

Shipbuilding and Fleet Organization

Quantity 0 builds a naval base. Quantity 100 + fleet number (0–15) × 10 + ship type (1–5) builds a destroyer through submarine in that fleet. Private operators decide new merchant ship construction.

Build on plains: quantity 0 refinery, 1 arsenal, 2 market, 3 port. Quantity 4 upgrades an owned port to level 2 (300 money, 40 stone, 20 wood, 10 goods).

Fictional containers

Ship, port and land capacity is counted in fictional containers, rounding up for each resource. Small merchant 128, Large merchant 1024; regular ports 256 and large ports 2048 per turn; land 64 per country pair per turn in both directions combined. Land freight costs 0.15 Funds per container, paid by the private seller to its national treasury. Treasury fractions below 1 Fund carry forward to the next payment.

Warship construction requires both funds and steel. A shortage prevents construction; both are spent only on success. Naval ports (0) require funds only. Row 6 (merchant) is for reference only; nations cannot build it (the private sector builds merchants). Types 7 and 8 cannot be built.

Build quantity: 100 + fleet number × 10 + ship type (1–5). Fleet numbers run from 0 to 15; 0 means Fleet 1. Quantities 1–5 alone also build into Fleet 1. Limits: 15 ships per nation, 5 per naval base and 5 per fleet. A new ship joins the selected fleet without changing its existing flagship.

AI overseas preparation: priority 1001, warship type 1 (Destroyer), unit type 0 (Infantry) with troop strength 10. Prepare a Naval Port, one transportable warship, then an occupying unit, one step per turn. Without a coast where a Naval Port can be built, the AI does not expand overseas.

Cruisers (range 2 hexes), Battleships (3 hexes) and Aircraft Carriers (4 hexes) in Normal (0) or Hunt (1) action fire at Naval Ports, Missile Bases, Defense Facilities and Undersea Bases owned by nations currently at war with them. Peaceful, pending-war, own and ownerless facilities are excluded. Valid mass-attack orders take priority. Exactly 3 actual hits destroy a facility regardless of technology; damage carries across turns and saves. Losing a Naval Port retains existing ships even above the reduced capacity, but restricts new construction. The Resupply and Repair command (72) requires an existing adjacent Naval Port of your own. Each effective facility hit gives +1 experience; destruction adds +0.

Warship wrecks remain for 10 turns starting with the sinking turn. Command 111 lets an adjacent own warship recover 20% of that wreck type's build steel, rounded up. Destroyer, Cruiser, Battleship, Carrier and Submarine yield 1, 1, 1, 3 and 1. Recovery fails if the treasury cannot hold all steel. Fee 0; success uses 1 turn, failure 0. Merchant cargo does not return and no hull is repaired.

Movement, Naval Combat and Sinking

Governments set port access, tariffs, transit fees, embargoes and export caps to private operators. Private operators fund trade and transport. Diplomatic transfers use physical transport, may wait or fail to arrive, and are tariff-free.

Up to 8 waypoints. The shortest navigable route avoiding mine cells is searched. Enemy firing ranges are not avoided automatically. Non-hostile ships may be passed only when an empty landing is reachable. Hostile ships are avoided immediately; other blockages trigger replanning after 1 turn. Merchants that burn Fuel per hex actually moved stop when out of Fuel and resume after resupply. Movement distance depends on river and current costs. No departure in a handling turn.

Set a Fleet destination to keep moving toward it on subsequent turns. Quantities 100–115 select a Fleet; 1000–1015 clear its target. Early-movement and normal ships move in separate stages, preventing double movement. Escort settings make ships follow the flagship.

Naval attacks select hostile enemy ships in range according to the attacker's abilities. Ships without anti-submarine ability cannot target Submarines, and Freighters do not attack. Ships in Cruise (2) or Stop (3) do not attack either. Pirate Ships lack anti-ship capability, so they do not acquire targets automatically (their raids on merchant ships, cruise ships and distant fishing boats follow a separate rule in the merchant section). Sea monsters (Whales) can also be targeted. Attack count, scatter and range use the ship table. Hits reduce HP; ships sink at 0 HP or below. Embarked troops and cargo are lost, restoring the original water and natural resources.

Innocent passage allows Freighters to pass through hexes occupied by your own ships or ships of non-hostile nations, but ships cannot stop in the same hex or stack. Passage is possible only if the remaining movement allowance for that turn reaches an empty hex beyond them; a line of ships or insufficient movement can block passage. Ships of nations preparing for war or already at war with you, and unaffiliated ships, cannot be crossed. If ships block a route, the Freighter waits 1 turn and tries to replan or detour on the next turn. A detected hostile ship triggers an immediate search for a detour. Warship movement does not use this passage rule.

Ships may pass through ports and naval bases but cannot stop on them. Ships at war with the owner, including the declaration period, cannot pass; the usual shallow-water restrictions still apply. A merchant ship stops before a port if its remaining movement cannot reach empty water beyond it. During automatic sailing, a warship may cross one adjacent port to the next empty hex (Destroyers are the only warships that can enter ports, as they are the only ones that can enter shoals). A manual one-hex move onto a port is rejected. Cargo handling and resupply take place from adjacent hexes.

Warship wrecks remain for 10 turns starting with the sinking turn. Command 111 lets an adjacent own warship recover 20% of that wreck type's build steel, rounded up. Destroyer, Cruiser, Battleship, Carrier and Submarine yield 1, 1, 1, 3 and 1. Recovery fails if the treasury cannot hold all steel. Fee 0; success uses 1 turn, failure 0. Merchant cargo does not return and no hull is repaired.

Cruisers (range 2 hexes), Battleships (3 hexes) and Aircraft Carriers (4 hexes) in Normal (0) or Hunt (1) action fire at Naval Ports, Missile Bases, Defense Facilities and Undersea Bases owned by nations currently at war with them. Peaceful, pending-war, own and ownerless facilities are excluded. Valid mass-attack orders take priority. Exactly 3 actual hits destroy a facility regardless of technology; damage carries across turns and saves. Losing a Naval Port retains existing ships even above the reduced capacity, but restricts new construction. The Resupply and Repair command (72) requires an existing adjacent Naval Port of your own. Each effective facility hit gives +1 experience; destruction adds +0.

Cruisers (range 2 hexes), Battleships (3 hexes) and Aircraft Carriers (4 hexes) in Normal (0) or Hunt (1) action may shell civilian targets only in nations currently at war: all town types (Town / Undersea City / New Town / Modern City / Metropolis), Farms, Factories, Large Farms and Large Factories. Valid mass-attack orders take first priority; otherwise military facilities are targeted first. Population values use units of 100 people; Farm and Factory scale values use units of 1,000 people. Each hit reduces current population by 10% rounded down, with a minimum loss of 1 when population is at least 1. Zero population stays unchanged and town terrain remains. Consecutive hits use the population immediately before each hit (default: 100→90→81). Each hit reduces Farm scale by 5 or Factory scale by 15. Below the minimum scale (Farm 1, Factory 1), they become Plains and Plains respectively, with scale 0. Ownership and war status are checked again at every impact; own, noncombatant, pending-war and ownerless targets take no damage. Ownership, troops, stocks and civilian cash are not directly changed, and no weather factor applies. Each effective hit gives +1 experience with no destruction bonus. Military facilities still require 3 hits regardless of technology.

Large Farms and Large Factories are also shelling targets when at war. One hit reduces Large Farm scale by 5 or Large Factory scale by 15. At or above the minimum scale (1 and 1), each keeps its large terrain type. Below that scale, they become Plains and Plains respectively with scale 0.

Cruisers, Battleships and Aircraft Carriers in Normal (0) or Hunt (1) action can damage only the armies of nations currently at war. An army tile becomes a target only when designated by Mass Attack (command 70, amount 2000); armies are not selected automatically. A land-directed shell that lands on a hostile army reduces its strength by 30–49 (units of 100 people), as an ordinary missile does, and strength below 1 means annihilation. Scattered shells aimed at facilities or towns can also hit armies, while facilities and towns on the same tile take their own damage. Own and noncombatant armies are protected. Shells aimed at ships or monsters do not damage armies when they miss. An effective hit gives +1 experience, with no sinking bonus for annihilation.

Merchant Classes and Routes

A private merchant ship that finds no way to its home port for 6 turns heads to a free port of its own country within 2 hexes. If there is none, the port where it unloaded becomes its temporary home port and it waits there for cargo. A ship still carrying cargo leaves the cargo in custody at such a port, its own or one of a country whose port is open to it (not at war, under embargo or with a closed port), or else at the nearest such port with a route, and that port becomes its temporary home port. The cargo still belongs to its private owner; if no ship collects it, it returns to the owner's private stock after 6 turns. A ship at a temporary home port looks for the way home again every 6 turns and returns when it finds one.

A private merchant ship waiting for cargo at a port with only one water cell as its way in does not stop there; it waits on a free water cell within 2 hexes of the port (sea or shallows with no fishing ground, nursery, mine or other ship). With no free cell it waits in the way in. When cargo comes it steps in for the loading and sails out. State merchant ships and warships are unchanged.

Neutral pirate ships also raid merchant ships, private and national (including distant fishing boats), under the same rule as cruise ships: pirates within 1 hexes, raid chance 25% per turn, sinking in 10% of successful raids; otherwise 50% of the cargo is stolen (a private trade cargo keeps at least 1 unit and the buyer gets back the payment for the stolen part; cargo of a one-way transport between countries [aid, auctions] counts as lost, and an auction is paid only for what arrives; a distant fishing boat loses fish on board; money and the cargo of exchanges between countries [including scheduled transport] are not stolen). The cargo of a sunk ship is lost, as when a warship at war sinks it.

Private cruise ships

Private operators build and sail automatically. Each port tile may be home to one cruise ship at most; the national limit is the number of ports. Private operators build a new ship only when it is expected to pay (rule below); existing ships keep sailing. Private cash pays construction; national funds and cargo handling slots are unused. An actual voyage to a different permitted port earns tourism revenue once for the owning private sector. Revenue per call falls as more cruise ships sail the world. Construction at home and continued waiting earn nothing; returning home after another port qualifies. At the cash cap, payment remains due and sailing waits; unpaid claims survive sinking. Losing the home port pauses the ship without changing ownership. A vanished owner has its hulls removed. Ships approach the destination through neighboring empty sea or shallows and take a detour by the rule below when one is needed. The military action Cruise is separate; there are no national control orders. Military capability-table costs and speeds do not apply. After normal naval actions, cruise ships sail and receive call revenue, then each ship rolls at most once per turn for nearby surviving neutral pirates. Docked and paused ships are also exposed. A successful raid either sinks the ship or steals a share of its latest unlooted call revenue, capped by private cash on hand. Fractions below one thousandth of a fund are rounded down; no revenue or cash means zero loss. National funds and bank deposits are untouched. Sinking alone does not confiscate past paid revenue.

Construction 100 funds, speed 2 cells/turn, HP 3. Revenue per new call is 10 funds × 10 ÷ (10 + other cruise ships in the world): half when 10 other cruise ships exist.

Private operators build a new ship only when its expected revenue over the 20 turns after construction covers the construction cost. The expectation is the expected number of calls times the revenue of one call once the new ship is counted. The number of calls comes from the distance between the home and destination ports and the speed. When the country's cruise ships have a record of the last 20 turns worth at least one ship for 20 turns, and that record shows fewer calls per ship, the record is used.

When no neighboring cell is closer to the destination, a ship searches for a detour with the same route search as merchant ships and follows the route it found to the end (searches of stopped ships, together with private merchant ships without a way home, are at most 4 per turn in the whole world; once every 4 turns per cruise ship). No new ship is built at a port with only one free water cell.

The destination is chosen only among ports reachable by water, the shortest sailing time first. The 3 nearest ports in straight distance get a route-length estimate (at most 8 estimates per turn in the whole world). A port reachable only through another port, or whose way in is taken by ships, is not chosen. When none of them has a route, or no estimate is left, the next nearest port by straight distance is taken and the choice is made again after 4 turns; a stopped ship that finds no detour also chooses again then.

Pirate raids: pirates within 1 hexes, raid chance 25% per turn, sinking in 10% of successful raids; otherwise 50% of unlooted revenue is stolen.

Distant-water fishing

Embarking and Disembarking

Embark selects a ship and loads your adjacent troops from direction 1–6 in the quantity field. Disembark also selects a ship and uses quantity 1–6 for the adjacent landing destination. Terrain and occupancy requirements must allow troop placement. Embarked troops are cargo and cannot occupy land, attack or counterattack. Ships carrying troops cannot be decommissioned.

Ships and troops never share a cell. Ships (private merchant ships, cruise ships, far-sea fishing boats, state merchant ships, warships and pirate ships) do not enter a cell with troops and do not choose a route through it. Troops board a ship only with Embark and never enter a ship's cell by their own movement. A private ship that already shared a cell with troops leaves them on that cell (it waits if the troops could not stay on that water).

Breakwaters and Sea Mines

Build a Breakwater on Shoal next to your territory for 500 ×100M JPY to protect a two-hex radius from tsunamis. Sea Mines are laid in deep Sea next to your territory; quantity 1–2 sets their damage. Laying cost is damage ×300 ×100M JPY; clearing your existing mine costs 20% of that. Mines damage ships on contact.

Mass attack (command 70, quantity 2000) lets Destroyer / Cruiser / Battleship / Aircraft Carrier / Submarine fire at explicitly designated mines within range in normal (0) or hunt (1) action. Range, error, shots and costs match normal fire. Only mines actually hit that belong to your nation or a nation currently at war with you are cleared. Peaceful, pending-war and ownerless mines are protected. Misses do not damage towns, facilities, ships, monsters or troops. Command 77 clears your own mines for the fee listed in the command table.

Naval Ports and Supply

Naval Port upkeep and Food, and ship Funds, Food and Fuel, are consumed each turn as listed. Ships that can pay all costs recover 1 HP up to maximum HP under the conditions below. Insufficient Funds or Food never lower warship experience or level. Repair and supply recover up to the maximum increased by experience; insufficient Fuel causes 1 HP damage. Repair at an adjacent naval port owned by your nation restores 1 HP for ten times that ship type's per-turn upkeep and Food costs. Supply comes from the owner's stocks and does not simulate overland supply-line transport.

After warships (types 1-5) pay all supply costs, they recover 1 HP with the probability for their current fixed climate belt: tropical 80%, subtropical 90%, temperate 100%, subpolar 90% and polar 80%. The cap includes experience bonuses; full hulls draw no lottery. Payment is the same even when no HP is recovered. Merchants, liners and fishing boats have no climate correction. Repair order 72 always recovers.

Faction

Unaffiliated nations can create a faction for 1000 ×100M JPY. Up to 8 factions may coexist. Membership requires an application and leader approval; each nation belongs to one faction. Applications expire after 12 turns. Queue reviews, cancellations, departures, expulsions, leadership transfers and renames from the faction panel on the development screen.

Reapplication waits after leaving, expulsion or dissolution: 6 turns. Leadership transfer deadline: 3 turns. Rename cooldown: 12 turns.

factions, membership and Meeting Rooms remain active for 3 turns after a dissolution notice. The leader can cancel the notice. If more than half of the other full members request a replacement, leadership passes to the longest-serving member among those requesting replacement (lowest nation ID breaks ties), and dissolution is cancelled. Replacement checks take priority even on the deadline turn.

Faction Meeting Rooms and shared screens require authenticated full membership. Meeting Rooms are archived on dissolution.

The private Faction map, opened by an authenticated full member, combines sight from all member nations. Enemy land units and warships outside your own sight become visible if another member can see them under the respective land or naval sight rules. Your normal nation screen still uses only your own sight; it does not combine Faction sight. The Faction screen also shows each member’s leader name, Funds, Food and first 15 queued plans.

During the past 48 turns, an AI-led Faction rejects applicants with at least 2 recorded departures, expulsions, or diplomatic cancellations after agreement. Human applicants undergo the same review.

Trade alliance

A trade alliance is separate from a military Faction. Each nation's private sector joins as one company per nation and may belong to one trade alliance. Any nation can found one by naming it with command 112; the founder becomes its leader. Command 112 also joins an existing alliance without approval. Command 113 leaves; rejoining any trade alliance is blocked for 10 turns. Members may use each other's friends-only Ports, and the transit fee at a member's intermediate Port is halved. When credited to the Port nation treasury, a remainder below 100 million yen carries forward. The half-rate fee is still paid and cargo passes when the treasury is full; the excess disappears. War, embargoes and Port closures take precedence.

Periodic shipments

The seller offers one shipment; acceptance binds both countries for 36 turns. The interval is set from one-way travel time when offered and cannot be cancelled after acceptance. A shipment is skipped for insufficient goods or payment, war, or embargo; the agreement continues. Offers expire after 10 turns and AI countries do not accept them. A receiving port holds up to 10 agreements, or 20 if large. Quantity uses the diplomatic exchange limit.

1. In the diplomacy panel, choose partner, goods, quantity and payment per shipment, receiving port, and seller freight limit. The interval follows one-way travel time; offers expire after 10 turns.
2. The buyer accepts an offer by ID and revision. Shipments recur for 36 turns; the accepted agreement cannot be cancelled.
3. The seller withdraws an offer before acceptance. An accepted agreement cannot be cancelled.

Long supply agreements

Private sectors automatically make long supply agreements between a nation that has lacked an item for 2 turns in a row and a nation that has had at least 16 spare units of it for 2 turns in a row. The partner and item are chosen from that turn's expected private sea trades; while slots remain, the search widens to nations with a surplus that are not among those trades (up to 8 pairs get a sea-route check per turn, with at most 4 new route searches; remembered routes are used first, and a partner that cannot be reached right now because ships crowd the way is skipped that turn). The goods travel on private ships. Each delivery is at least 16 units, at most one ship's load and no more than the buyer's private sector can pay for all deliveries with its current cash; the interval is the round trip of the route (at least 4 turns), and there are 2 deliveries. The price stays at the trade price of the day the agreement was made. Payment is made on delivery (tariffs as in ordinary trade). Agreement ships leave before ordinary trades, and the selling private sector keeps back the next delivery. If a delivery has not arrived by its deadline (the agreement turn plus that many intervals plus 3 turns of grace), the side that failed (normally the seller; the buyer if its private sector lacked the cash or storage) pays 10% of the remaining value to the other private sector, and the agreement ends. A breach is kept in the public diplomatic record. When pirates take agreement cargo, it is not a breach: the taken amount counts as delivered and the agreement continues (nothing is resent, the buyer pays only for what arrives, and the seller loses the cargo). If war, an embargo, a port closure or similar stops ordinary trade, or a nation or an agreed port disappears, the agreement stops without a penalty. At most 32 agreements run in the world, and at most 3 per nation. Allowed partners and goods are chosen under Trade and ports on the development screen (everything is allowed at first; changes do not end agreements already made).

Auctions

A country lists goods from its treasury and other countries bid. Listing (command 92) holds the goods from the treasury when it runs, and bidding (command 93) holds the bid amount plus a freight share. When another country bids higher, both go back at once. On the closing turn the highest bid wins. The goods travel by land or merchant ship, the same way as diplomatic transport between countries, and the held payment goes to the seller when they arrive. The buyer pays the freight out of the held freight share, and what is not used goes back to the buyer. If pirates steal part of the goods on the way, the seller is paid only for what arrives and the rest of the payment goes back to the buyer. If they cannot be delivered, the goods go back to the seller (except any lost at sea) and the payment and the rest of the freight share go back to the buyer. Without bids, the goods go back to the seller. A listing, and a sale that is being shipped, cannot be withdrawn.

The period is 3 to 24 turns. A bid made when fewer than 2 turns remain moves the closing turn to 2 turns after that bid (up to 6 times). A new bid must be at least 5% (and at least 100M JPY) above the highest bid. One country can have 3 open lots and the world 40. The listing fee is 0% of the minimum price. A freight share of 10% of the bid is held together with the bid (after winning, this is the most the shipping can cost). Goods not delivered within 36 turns go back.

You cannot bid on a lot of a country you are at war with or preparing war against, a country under embargo (including closed land checkpoints), or a country whose port is closed or open only to friends. This is checked again at closing; if trade is not allowed, the sale is called off and the goods and payment go back.

AI countries (rule AI and LLM countries) list and bid once each turn. They list the item with the largest value among goods they may still sell to their private sector: the smaller of 50% of that limit and 600 ×100M JPY worth, at a minimum price of 90% of their trade price, for 6 turns. They skip an item that already has 2 open lots in the world. Under threat they do not list ammunition, fuel or steel. They bid on items below their treasury purchase target when the lot is at most twice the shortfall, up to 115% of their trade price including the freight share. They hold at most 20% of their money in bids (with the freight share) and keep 1000 ×100M JPY in the treasury.

Entering from the auction box on the Trade and ports tab of the development page fills the command fields. When writing a command directly: for listing (92), x is the item number (0 to 7 are resources, 8 is food), y is the period, the quantity field is the quantity and the target field is the minimum price. For bidding (93), the target field is the lot number and the quantity field is the amount.

• List for Auction: Put treasury goods up for auction. Enter it from the auction box on the Trade and ports tab of the development page (item, quantity, minimum price, period). The listed quantity is held from the treasury until the auction closes.
• Place Auction Bid: Bid on a lot listed by another country. Enter it from the auction box on the Trade and ports tab of the development page (lot number, amount). The amount and a freight share are held from the treasury and returned if another country bids higher. The buyer pays the freight, and the unused part comes back.

Coalition

Coalition: a coalition can form only while one dominant power exists. The dominant power is the nation that holds at least 30% of all land in the world, neutral land included (water tiles such as sea, shallows, ports, ships and sea mines are not land), and at least 2 times the land of the second-largest nation. Each land tile taken in war within the last 48 turns counts 1 points and each war it declared counts 10 points; the points fall steadily to zero over time. When the dominant power reaches 30 points, a coalition forms. When it stops being the dominant power, the coalition dissolves and current wars end under the normal ceasefire rules.

AI nations (rule AI and LLM nations) join on their own. Human nations receive an invitation and join with command 134 and leave with command 135. The dominant power, nations in its military faction and nations with a friendship treaty with it cannot join, and members that become so leave. Faction rules come first: an AI nation whose faction includes a nation with a friendship treaty with the dominant power does not join on its own.

Defence pledge: when the dominant power declares war on a coalition nation, every coalition nation joins that war (never against its own faction). Embargo: private trade, land routes, port trade, periodic transport and diplomatic transport between coalition nations and the dominant power stop, and they cannot enter each other's ports. Joint declaration: when the coalition's combined strength (population / 100 + army strength) exceeds the dominant power's, AI coalition nations declare war together and human nations are notified (they decide for themselves). Joint declarations by the coalition do not count toward the three-nation limit on declarations received. Ordinary declarations are limited to three attacking nations. The next joint declaration can come only after all those wars have ended and 24 turns have passed since the previous one.

Turn Processing Order

1. Prepare AI plans, then advance the clock and turn. Initialize resource accounting, reclamation unlocking, faction, naval, market and land-transport turn state, then accumulate natural resources and spawn neutral enemies.
2. Determine country order, then process diplomacy, national income, consumption, industry, naval supply and plans. Zero-turn commands advance to the next plan. After all national plans, process private shipping upkeep, diplomatic transport, domestic trade and private maintenance, then private land trade and shipping plans.
3. Process ports, early naval units, ports, terrain growth and single-hex disasters, normal naval units, ports, land movement and combat, then national and global disasters and updates to territory, income and survival. Private ships follow class movement limits, routes and handling capacity; unfinished work carries over with cargo ownership preserved.
4. Settle domestic sales from private stocks to households, then finalize faction operations using country survival status. Clear abandoned territory, rank population, and check victory and game-end conditions.
5. Take a backup and update world prices. Record population and troop statistics, reflect treasury changes in the accounts, and finalize resource accounting.
6. Finalize processed-plan markers, history and logs, and save the world data together. Then record one statistics row and update the logs and public pages.

Saving and Backups

The world map, nations, factions, Markets, plans and visitor boards are saved together so that they always belong to the same turn. If a save goes wrong, the previous consistent save is restored.

Backups are taken every 1 turns and 6 copies are kept. Restoring the world to an earlier state does not roll back Meeting Room posts or published logs and statistics. Statistics are not used to decide victory or inventories.

LLM Mode

Human countries do not receive AI fallback. This policy takes effect after an administrator enables AI, or when AI fallback runs in LLM mode.
