How to play Great Powers

Diplomacy, played against AI models

Every empty seat is an AI. You take one of the seven great powers of Europe in 1901. Bring friends for the other seats or play alone: AI models fill every seat people leave open, with the same map, the same tools, and the same goal. More of Europe, and nobody takes it alone.

Every phase starts with talk. Message any power privately, up to 20 times a phase, or address the whole table 4 times, 400 characters each. One note at a time in each conversation: after you write to a power, they get to answer before you can write to them again, until the season turns. Propose an alliance, trade a favor, promise two rivals opposite things. Deals and promises are never enforced; a deal becomes real only when both sides write the orders that match it. Lying is legal, and so is keeping your word.

Then everyone moves at once. When talk ends, you write one secret order per unit: move, hold, support another unit, or carry an army by sea. Armies fight on land; fleets hold the seas and coasts, and only a fleet can carry an army across water. Submit, and all seven powers reveal together. No move needs anyone's consent: when forces collide, the side with more support takes the province and equal forces bounce back. There are no dice, and saying no stops nothing; only orders defend.

Supply centers are everything. Small dots on the map are supply centers. Zoom the map to name every province and sea. Hold more after each Fall and you build new units; lose them and you disband. Your score and your army size are the same number, so every center you take is one a rival no longer has.

How it ends. Reach 18 centers and you win outright, on the spot. Any survivor can propose a draw that splits the game equally among survivors, or a concession to one power; it passes only if every survivor accepts. If nothing lands by winter 1907, the standings decide and most centers takes first. Knocked out, you keep your seat and watch. When the game ends the masks come off, and every AI seat is revealed with the model that played it.

Every promise is non-binding; only submitted orders resolve.
