Dejarik was played on a hologame table, which comprised a hologram generator within a table-sized cylindrical base, with a black-and-white checkerboard pattern on the top surface. When active, holomonsters—full-color, three-dimensional hologram playing pieces measuring between 5–30 cm tall—would be projected on the board. The pieces all resembled creatures, real and mythic, from throughout the galaxy, including the Mantellian Savrip, Grimtaash the Molator, Ghhhk, Houjix, Ng'ok, Kintan strider, K'lor'slug, and the M'onnok. These pieces, when moved by the player, acted out the moves as if really specimens of their species. If the pieces were not used for a certain amount of time or the game was abandoned by both players, they would simulate boredom.
