Damas or Checkers is a strategy game which involve diagonal moves of pieces and mandatory captures by jumping over opponent pieces.
Instructions:
Your pieces are below the half of the board. Yours and your opponent's pieces can move only in diagonal, one square at the time, and always forward (for you, that is "up"). You must clear from the board all the pieces of your opponent jumping over them in diagonal. If a piece reach the first enemy line, it become able to move back. If one of yours is in position to eliminate an enemy piece, you must do it, even if you just did it with another.
