Multi-Chess is a multiplayer chess strategy game played on a single board. Every player permanently owns specific pieces — and only the owner may ever move them. Players cooperate by transferring initiative, not by controlling each other's pieces.
Unlike traditional chess, no player controls the entire army. Instead, every chess piece belongs to exactly one player.
🎯 Think of it like watching someone else's game — you don't control the whole plan. Your only job is to find the best move for your pieces when the initiative comes to you. Contribute your one solution to the puzzle, then pass it on.
The game is built around four core principles:
Every time a player receives the initiative, they have exactly two choices.
Move one of your own pieces using the normal rules of chess. You may never move a teammate's pieces, even if doing so would help the team. Only the owner of a piece may move it.
Instead of making a move, you may transfer the initiative to any teammate. The receiving player does not gain control of your pieces. They simply receive the opportunity to make one legal move with one of their own pieces — or transfer the initiative again.
Every piece belongs to exactly one player. Ownership never changes during the game. Only the owner may move that piece. Nobody — not even your teammates — may ever move it for you.
Whenever you receive the initiative, every decision is yours. You may move one of your own pieces or transfer the initiative to any teammate. Nobody can tell you what move to make.
Ownership never changes. Initiative does. You are not giving permission to move your pieces — you are giving the opportunity to move one of their own pieces.
Freedom comes with responsibility. If your queen wins the game, everyone knows it was your move. Victory belongs to the team. Responsibility belongs to every player.
The only communication is through the moves themselves.
As teams become larger, ownership becomes more specialized, but every piece always has exactly one owner.
Multi-Chess follows the standard rules of chess.
The difference is not how you win. The difference is who is allowed to move each piece.
