The game is played in two teams: Yellow and Red play against Green and Blue. Move order: Yellow, Green, Red, Blue.
The teams win and lose together. The game ends at the first checkmate, and the team whose member delivered the mate wins. The teammates cannot capture each other's pieces.
Details: Four-player chess.
- The two pawn groups of each player move in different directions, both towards the nearest opponent's base.
- Pawns promote when they reach the opposite side of the board, where they cannot advance further. Different pawns may have different distances to promotion.
- Castling is possible with any of the two rooks, and in either case both the king and the rook moves two squares.
