The game beyond backgammon has been DISCONTINUED

Ultragammon is a unique 3D board game that rivals the classic skill games such as Backgammon and checkers. Pieces are stacked in play to gain markers.  Ultragammon 2.5 featured several new and innovative rules. The markers can then be moved to create dynamic scoring options.
