Tri-Chess is played on a hexagonal board made up of 217 hexes in three colors. Each side has an additional bishop and two extra pawns, with the baseline being RNBKBQBNR. The King moves to any adjacent hex; the Queen and Bishop cannot pass between two occupied hexes; a Pawn moves one step as a Bishop (with an opening two-step being permitted) and captures with a two-step Rook move. When a player is checkmated, their forces are immobilized; the first player to capture the king then takes over the immobilized forces. The capture can be made by either of the remaining players. Note that despite the identical name and designer, this game is not identical to Tri-Chess.
