The digital evolution of Trigammon™

TrigammonX™ is a three-player backgammon 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, bearing off and three-way strategic interaction of the original game while adding the advantages of digital play.

Play with:

3 Human players • 2 Humans + 1 AI • 1 Human + 2 AI opponents

No download or account is required. Just open TrigammonX in your browser, hit the PLAY button and play on desktop, tablet or mobile.
