TrigammonX is the digital evolution of Trigammon, the three-player strategy board game originally developed by William “Bill” Bailey and Dennis Angelica in the late 1970s. Inspired by traditional backgammon, Trigammon was created to explore how movement, timing, blocking, risk and player interaction could be adapted for three players. Rather than simply adding another player to a standard backgammon board, the game uses its own three-sided layout and approach to three-way play. TrigammonX is being developed to bring that experience to computers, tablets and mobile devices.
From tabletop to digital play
Decades after the original Trigammon concept was created, Bill returned to the project and began refining it for a modern audience. Alongside the updated physical board game, development began on a digital version designed to make three-player gameplay easier to learn, test and enjoy on modern screens. That digital project became TrigammonX.
