Join the DiscordPut your nation on the world ranking at the end of a season, and see who held the prize in each world.
See the rankingTerrastate is a free grand strategy game in the style of Planetarion that runs in your web browser. You lead one nation against 500 AI nations on a world map of 25 theaters: build an economy, research, raise an army, join or found an alliance and fight for the Nexus, the one region that decides the season.
Each world has a board game of hidden ranks for one opponent: Hidden Command (Terrastate), Veiled Legions (Romaterra) and Sealed Orders (Ironfront). You set up your army in secret on a 9 by 9 board, and the enemy only sees the backs of your pieces. Play against four computer commanders on four levels, or with two players on one screen. Before the battle you open a sealed order for extra points. A battle takes about 15 to 30 minutes. Free, in the browser, also on a phone.
Yes. Terrastate, Romaterra and Ironfront are completely free, and so are their board games and mini games. There are no payments, no ads, no account and no download. It is a non-commercial hobby project by Wim Kamphorst from the Netherlands.
No. Open playterrastate.nl/play.html in any modern browser and you are playing. You can install it as an app from the browser if you like, and it keeps working offline. Your saved game stays in your own browser.
Yes. Terrastate, Romaterra and Ironfront are built for both phone and desktop, with a big END TURN button under your thumb on phones. The mini games work on both too.
Take the Nexus, build the Earth Command Center on it and hold it for 12 ticks. If nobody manages that, the Last Battle decides: the whole world marches on the Nexus and whoever holds it the longest wins. In Romaterra the prize is Roma and the Imperial Palace.
No. The AI nations pay exactly what you pay and only know what they have scouted. Rival alliances have a war council that picks targets, signs pacts, scouts and strikes together, but always with the same rules as you.
You choose: a Quick season of 200 turns, Standard of 400 turns or Epic of 840 turns. It is turn-based, so you can end each turn yourself, or let it run automatically, one turn every 1, 5 or 15 minutes. Difficulty is Recruit, Veteran or Warlord.
New players get Field Training: five small tasks that teach you by doing, including a war game that explains your first battle. You can skip it at any time.
Not in the grand strategy games yet. The mini games have duels with a friend. What you play now is Season 0: single-player against AI nations, the training ground for the live world. The live world, one shared season with real people as the other nations, opens when 100 commanders have joined the waitlist on the Terrastate Discord.
Season 0 is the single-player phase of Terrastate, Romaterra and Ironfront. You learn the game against 500 AI nations while the community grows. When 100 commanders are on the Discord waitlist, the live multiplayer world opens. Players from Season 0 are marked as Founding Commanders.
Update 20.4 (November 2026) finishes a series of updates that give buildings and research real choices, for all three games: buildings you give an order (a production line, power priority, readiness, a harvest, holding the line with bunkers), an order for each national path building, export contracts from the computer nations, trade routes, mines that wear out, five world wonders each season and army ranks up to Elite. Every update in full is on the updates page.
Next to each grand strategy game there is a small mini game of its own: Terrastate: Conquer, Romaterra: Imperium and Ironfront: D-Day. It is one quick battle on a hex map: you give every unit an order, end the turn, and everyone moves at once. The grand strategy game is the main game; the mini game is a separate, shorter game with its own save. Free, in your browser and offline once played. All three are at playterrastate.nl/tactics/. Open the mini games
Ironfront is the third era of the game: Europe at war in 1944, on a map of real fronts and towns, with invented nations and leaders. You gather pounds, rations, coal, steel, petrol and radio gear, raise infantry divisions, tank battalions, artillery and strategic bombers, and win by holding 2 of the 3 Capital Sectors with a GHQ Bunker for 12 ticks. It also has its own battle layer: battle orders every tick, field works, radio intel with feints, and allied help that has to arrive in time. More about Ironfront.
Romaterra is the same game set in the age of Rome. You gather denarii, grain, timber, iron, livestock and bronze, train legionaries, cataphracts, ballistae and war elephants, and fight to take Roma and hold the Imperial Palace.
Terrastate is inspired by tick-based browser strategy games such as Planetarion, with the alliances, scouting and timed attacks of that genre, plus the map and diplomacy of a grand strategy or 4X game. The difference: you play against hundreds of AI nations, at your own pace, without waiting for other players.
I make these games in my spare time, with the help of AI tools. The grand strategy game is inspired by Planetarion, the classic tick game: real turns, real armies on the move, and allies who matter. Tell me what you think, or what broke, on Discord.
