Holochess was a chess game that utilized holographic representations of the playing pieces, often exotic aliens. It was played for entertainment and gambling. The rules differed from regular chess, as it was played on a circular board, rather than square. Holochess differed on crucial points from dejarik and holochex. The Tralla Room on the Coral Vanda had several holochess tables.
