Qix was released in October 1981.
Also released as a cocktail model. In Japan, the cocktail version is known as "T.T Qix
The author named the game 'QIX' (pronounced 'KICKS' and not 'QUIX') because his car registration/number plate at the time was : 'JUS4QIX'.
Qix is the first 'drawing game', a truly original game. Also the first totally Taito American game, Qix initially did big numbers, but quickly died when players discovered the machine was 'unbeatable'. Having a googolplex of possible combinations, there was no singular pattern to the game and players lost interest.
A Qix unit appears in the 1983 movie 'Joysticks' and in the 1984 movie 'The Karate Kid'.
