How to Play
In the Webkinz Game "Checkers," players must make all their pieces jump over their opponent's pieces. You choose your color, then lay the pieces out. After this, you move your pieces diagonally. You can only move them forward. Stay on the same color of square throughout the game. You want to be able to jump over your opponent's piece, wich means if his piece is in between your piece and an empty space, you'll be able to jump over it. If you reach the other side, or the opponent's starting side, you become a king, who can move backwards and forwards!
