The perfect diversion for home and club.* * *The board consists of a 4 x 4 grid. The pieces are numbered 1-4 in four different colors (making 16 in all). In the basic game, each player removes a '1' piece, and then takes turns jumping and removing pieces (like in checkers, but orthogonally, not diagonally). Each piece that is jumped must be of a different color than the one which is moved.The game ends when one player cannot make another move. If the remaining pieces are of different colors, the player who CANNOT move takes the remaining pieces and adds their total to his score. However, if the pieces are all of the SAME color, the PREVIOUS player (the one who made the last move) gets the points, plus a 10-point-per-piece bonus. If the remaining colors are all black, the bonus is increased to 20 points per piece.Needless to say, there are numerous variations to these rules among the 39 other games that can be played with this set. - BoardGameGeek
