Move on the dark squares
Play against the computer on an eight-by-eight board with twelve counters each. Ordinary counters move one square diagonally forwards. Select a counter and a legal destination. Reaching the far row crowns it; a king can move one diagonal square forwards or backwards.
Take every required jump
When a capture is available, you must take one. Jump an adjacent opposing counter into the empty square beyond. Ordinary counters capture forwards; kings can capture backwards too. Continue with the same counter while it can jump. Any available capture path is allowed; you need not take the longest.
Finish or draw
Reaching the king row ends that turn, even during a capture. Win when the opponent has no counter or legal move. The same position and turn three times draws, as do 80 consecutive single-player turns without a capture or an ordinary counter moving.
