Rules of the game:
Players play on an 8x8 checkerboard.
The first move is made by the black checkers.
Uncrowned pieces (men) move one step diagonally forward, and capture an opponent's piece by moving two consecutive steps in the same line, jumping over the piece on the first step. Multiple enemy pieces may be captured in a single turn provided this is done by successive jumps made by a single piece; the jumps do not need to be in the same line but may "zigzag" (change diagonal direction). Men can jump only forward.
When a men reaches the farthest row forward, it becomes a king, and acquires additional powers including the ability to move backwards and capture backwards. If a men reached the last row at the time of capture, it becomes a king and stops, even if it is possible to continue capturing.
Capturing is mandatory. In several variants of capturing the player chooses the option of taking at his discretion, and in the chosen variant it is necessary to beat all available checkers.
The player without pieces remaining, or who cannot move due to being blocked, loses the game.
