Xiangqi

Shift your pieces according to their individual movement rules. The General can only move one square at a time within the fortress. Mandarins can only move diagonal moves within the palace. Elephants move exactly two squares diagonally and cannot jump over pieces. Horses move one square straight and then one square diagonally, if not impeded by adjacent pieces. Rooks move any number of squares straight, making them powerful attackers. Catapults move like chariots but must require a screen piece to capture exactly one piece. Pawns move forward one square and capture diagonally after crossing the river. Capture the opponent's general to win the game. Strategize your moves carefully to checkmate the computer opponent.
