Open a played game
Four games with their turns already written: open one at its last turn, read the chronicle, each turn's report and the ministers' views and answers, then watch the borders move in the timelapse.
The turns so far were written for these games. Play on and the demo's simple offline game master takes over: it changes little. The real game master needs the desktop app and a ChatGPT account.

Twelve turning points. Any country. The game master is a language model that knows the era.
The Shot at Sarajevo
The Archduke is dead, and a world war is a month away unless someone stops it.
Hitler Comes to Power
Hindenburg makes Hitler Chancellor, and his conservative partners are sure they can keep him in check.
The Invasion of Poland
The Wehrmacht has crossed into Poland, and in two days London and Paris must decide whether to fight.
The Korean War
North Korean tanks cross the 38th parallel, and Washington has hours to decide.
The Space Race
A Soviet rocket puts the first satellite into orbit, and every capital hears its beep.
The Gulf of Tonkin
North Vietnamese boats attack the destroyer Maddox, and Johnson wants a free hand.
The Yom Kippur War
Egypt and Syria strike on the holiest day of the Jewish year, and Arab oil is about to become a weapon.
Into Afghanistan
Soviet troops cross the Amu Darya, while in Tehran the American hostages enter their third month.
The August Coup
Gorbachev is locked up in Foros, tanks are in Moscow, and the Union is still alive – for now.
NATO Bombs Yugoslavia
Rambouillet has failed, and NATO's first cruise missiles fall on Yugoslavia.
Euromaidan
The eighth week of the Maidan: parliament has passed the "dictatorship laws", and Kyiv is on the edge.
The Invasion of Ukraine
Missiles strike across Ukraine, columns head for Kyiv, and the world is watching.
How it plays
Four games at four dates: Poland in 1939, Austria-Hungary in 1914, the United States in 1964 and Ukraine in 2022.
Orders in your own words
Write what your government does, the way you would say it: break out across the Vistula, ask Bucharest to let the arms through, rename a city, rewrite a law. Pick how long the turn lasts, a week to a year. Orders are intentions; the game master decides how far each one gets.
The turn comes back as a chronicle
The story comes first – a headline, a report and a verdict on every order: done, partly, failed – then the world and home are written in. On the map arrows show the offensives and the red line the front, running through provinces between the towns each side holds.
Ministers of the day
Eight ministries led by the real ministers of the date, each with a character, ability, loyalty and interests of their own. They answer from what they know on that day, take directives and draft orders, and after each turn give their view in their own window – objecting when the government goes against their causes. Asking costs no game time.
Politics at home
The parliament seat by seat – here the Verkhovna Rada on the budget for 2023 – the parties, the next election on the real calendar, unrest and plots. Bring a bill to a sitting, speak for it yourself and see how each party leans before the vote.
An economy that keeps its books
A budget in money of the day – here Austria-Hungary's in August 1914: taxes, the army, industry, the deficit, the debt and the reserves. A war economy, rationing, war bonds; trade, sanctions and deals for grain, oil or arms each turn.
An army counted piece by piece
Soldiers by training, every rifle, gun, tank, plane and ship on the books, the armies as they stand, the fronts and each side's strength. The general staff answers on the panel itself.
Research racing history
Seven directions of research, each with its share of the money, the year of technology it has reached and the next breakthrough, ahead of history or behind it. Ask the science minister for a new split, and apply it or not.
Other countries, as you know them
Wars, pacts and organisations of the date, each with its terms. Under fog of war another government's figures are your own estimates – a range, "≈", a rumour – as good as your alliances, borders and spies make them. Call the Security Council and speak there yourself.
The world as any country sees it
Pick any country and the diplomatic map shows the world through its eyes: allies, partners, pacts and enemies. Here the United States in 1964 – allies on every continent, and a war in Vietnam.
Seven maps of one world
Politics, terrain, fertility, people, resources and transport – and the diplomatic view: about 2,700 provinces, with the railways, ports and towns of the era.
Share a turn
Any turn as a picture: its headline over a map of what changed, ready to post.
Replay the game
The whole game as a timelapse of its borders, turn by turn, saved as a video.
