Tri-Hex Chess

Game over

Waiting for the host to start a rematch…

How to play

Three players — Ivory, Crimson and Azure — move in turn on a hexagonal board of 169 cells.

• Rook slides through the 6 neighbouring directions.
• Bishop slides along the 6 diagonals (it jumps the gap between two cells and stays on one of the three cell colours).
• Queen combines rook and bishop.
• King takes one step in any of those 12 directions.
• Knight leaps to any of the 12 cells at distance three that are not on a straight or diagonal line.
• Pawn steps to either of its two forward neighbours (two steps on its first move). It captures on those two cells or on the cell straight ahead. It becomes a Queen on reaching the far edge or an opponent's home edge.

You may never leave your own king attacked by either opponent. A player who is checkmated — or whose king gets captured after a discovered attack — is out, and their army leaves the board. A player with no legal moves who is not in check passes. Last army standing wins.
