Free Checkers Game Online: First choose the difficulty level if you are going to play against the computer or choose your friend as your opponent. You will be playing as RED and red starts the game. There are simple checkers rules: Starting with Red, the players take turns moving one of their own pieces. A 'piece' means either a 'man'--an ordinary single checker or a 'king' which is what a man becomes if it reaches the last rank. A man may move one square diagonally only forward - that is, toward the opponent - onto an empty square. A 'king' may move back and forward.
Captures are mandatory. If a square diagonally in front of a man is occupied by an opponent's piece, and if the square beyond that piece in the same direction is empty, the man may 'jump' over the opponent's piece and land on the empty square. The opponent's piece is captured and removed from the board.
If in the course of single or multiple jumps the man reaches the last rank, becoming a king, the turn shifts to the opponent. No further 'continuation' jump is possible.
