Xiangqi

Shift your pieces according to their unique movement rules. The King can only step one square at a time within the nine-pointed star. Mandarins can only move diagonal moves within the palace. Elephants move exactly two squares diagonally and cannot cross the river. Knights move one square straight and then one square diagonally, unless obstructed 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 attack sideways after crossing the river. Remove the opponent's general to win the game. Strategize your moves carefully to checkmate the computer opponent.
