Dejarik, also known as holographic chess or holochess, is a primarily-fictional board game appearing in the Star Wars space opera franchise that uses holographic figures as pieces. The game has been roughly described as that universe's equivalent of terrestrial chess since it is played on a board with a chequered pattern, each piece has a specific way of moving and attacking, and if it lands on a spot occupied by an opponent, it destroys the other piece. Over the years, several official and fan-made replicas have been made. As of 2021, no single, official rule set for the game has been released, and instead, a number of different rule sets (mostly designed by fans) for the game co-exist. Even the number of figures to be used in the game is unclear, although the best known variant uses eight. The game debuted in the 1977 film Star Wars, in a scene on board the Millennium Falcon. It is notable as one of the classic, early examples of holograms, 3D and AR in fiction. Origins and history Dejarik first appeared on screen in the 1977 space opera film Star Wars. In a scene lasting about 15 seconds, while traveling from Tatooine to Alderaan aboard Han Solo's light Corellian space freighter the Millennium Falcon, the Wookiee Chewbacca plays the game against the droid R2-D2. When R2 seems to be winning, Chewbacca rages, to which C-3PO comments on his useless anger. Han Solo then chimes in on how it is better not to displease Chewbacca, since Wookiees are famous for ripping their opponents' arms, at which point a scared 3PO changes his mind and suggests that R2 "let the Wookiee win". The dejarik board later appears when the starship is flying from the Death Star to Yavin IV, as Luke Skywalker sits in front of it, mourning Obi-Wan Kenobi's death at the hands of Darth Vader. The movie prop representing the game used in the scene was designed and created by Phil Tippett and Jon Berg. The game later made appearances in a number of Star Wars media, including the television series Star Wars: The Clone Wars and Star Wars Rebels. In the 2015 film Star Wars: The Force Awakens, Finn briefly activates the Falcon's dejarik board, and in 2018's Solo: A Star Wars Story, Chewbacca and Tobias Beckett play the game aboard the Millennium Falcon.
