The aim of the game is to be the first player to remove three marbles from the board. However, in this shifty strategy game, the route can be altered by sliding the movable squares, leading you or your opponent completely off-track! Will you move a marble or slide a square? The choice is yours! But watch out as your opponents are attempting to negotiate the "board" first. For 2 or 4 players. No option for 3-player game.
