Publisher's Catalog The backgammon player featured in Personal Computing (August 1979) is now back in a faster, even better version! The game of logic of the new Gammon Challenger has been improved for extra speed, and there are more special features than ever. Choose one of three levels of play, but don't get too ambitious--Gammon Challenger will put your skill to the test at all levels. For serious players, the "doubling cube" option can be used for added excitement. There are other computer backgammon games, but none quite like Gammon Challenger.
