The game was used as a display piece in the Ten Forward lounge aboard the USS Enterprise-D (much like the Terrace board game), but not primarily as a game unit. Rather, it was possibly meant to be a "wait call" device to signal a server over to your table. The unit was used as a game in the episode "Ethics" , where Deanna Troi and Alexander Rozhenko played it while waiting for Worf to undergo his spinal column replacement surgery. Another crewmember was seen playing with the game in "The Vengeance Factor" and it appeared prominently in the episode "Ensign Ro" .
