Checkers Solitaire

The goal is to place all 8 pieces on squares so that no 2 pieces are in the same row, the same column, or the same diagonal. To place a piece, just click on a square where you want it placed. If later you want to remove that piece, just click it again. If the placement of a piece violates the rules, the square will change to pink and the offending piece(s) will be in a yellow square. Just click on the pink square to remove it and try another location.
