    Abstract: The game comprises a flat, generally square board divided into smaller squares, two classes of tokens for placement on the board including markers and bridges, and a deck of standard playing cards less queens, kings and jokers. The tokens are preferably colored so that the tokens of each of the game's players can be readily identified. The cards are used to determine the placement of the beginning tokens as well as the order of play throughout the game.
