Checkers' chess pieces can only move along an oblique angle, with one move at a time. If a player's piece is adjacent to the opponent's piece and there is a space after skipping the opponent's piece, the player can choose to skip and eat the opponent's piece. In some cases, players can perform continuous jumps and eat multiple chess pieces. When a chess piece reaches the bottom of the opponent's board, it can be upgraded to a "king" with stronger mobility.
