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[a] 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.
