The digital evolution of Trigammon™

TrigammonX™ is a digital three-player backgammon-style strategy game, bringing the original Trigammon™ tabletop game to computers, tablets and mobile devices.

Originally created by William “Bill” Bailey and Dennis Angelica in 1979, Trigammon was designed so three people could enjoy backgammon-style play together on one purpose-built board. TrigammonX takes that concept online, preserving the racing, blocking, hitting and strategic interaction of the tabletop game while adding the advantages of digital play.
