Rules
Pieces sit on intersections. Select a piece to see legal moves; dots move, rings capture.
Horses and elephants can be blocked. Cannons need one non-cannon screen and cannot capture cannons.
Generals and guards stay inside palace lines. Chariots and cannons can use palace diagonals. Soldiers move forward or sideways, plus forward palace diagonals in the enemy palace.
You may pass only when not in check. Checkmate ends the game.
