Kwik Snax is an arcade style maze video game play developed by the Oliver Twins and was published in 1990 by Codemasters for the Amstrad, Spectrum, Commodore 64, DOS, and Amiga. It was the fourth game in the Dizzy series and is considered a sequel to Fast Food. After the Oliver twins had completed Operation Gunship they wanted to release another puzzle game similar to Fast Food which only required two weeks of development time, however unexpectedly it required much more time. The game was also re-spelled "Kwick Snax" for re-releases of the game, to avoid copyright infringement with the car servicing and repair company, Kwik-Fit who owns copyright on the spelling of the word "Kwik".
