Ultimate Play the Game was founded by brothers [[Tim and Chris Stamper]], along with Tim's wife, Carol, from their headquarters in [[Ashby-de-la-Zouch]] in 1982. They began producing multiple video games for the [[ZX Spectrum]] throughout the early 1980s.<ref name=best>{{cite web|title=The Best of British - Ultimate|url=http://www.crashonline.org.uk/51/ultimate.htm|publisher=Crash|access-date=13 August 2015}}</ref> The company were known for their reluctance to reveal details about their operations and then-upcoming projects. Little was known about their development process except that they used to work in "separate teams"; one team would work on development whilst the other would concentrate on other aspects such as sound or graphics.<ref name=best/> While developing ''Jetpac'', the Stamper brothers closely studied the burgeoning Japanese gaming market and had started to practice developing games for their then-upcoming console, the [[Nintendo Entertainment System|Famicom]], later predicting that the ZX Spectrum had a limited lifespan.<ref name=sabre>{{cite journal|title=The Ultimate Hero: The Complete History of Sabreman|journal=Retro Gamer|date=February 2010|issue=73|page=27|url=http://scans.bytemaniacos.com/en/retro_gamer/Retro_Gamer_Issue_073.pdf|access-date=23 August 2015|publisher=Imagine|url-status=dead|archive-url=https://web.archive.org/web/20151004151212/http://scans.bytemaniacos.com/en/retro_gamer/Retro_Gamer_Issue_073.pdf|archive-date=4 October 2015}}</ref>

''Jetpac'' was one of the few Spectrum games also available in a [[read-only memory|ROM]] format for use with the [[ZX Interface 2|Interface 2]], allowing "instantaneous" loading of the game when the normal method of cassette loading took minutes.<ref name=interface>{{citation | title=Interface Games are Fast but not Furious | journal=[[Sinclair User]] | issue=24 | pages=54–55 | publisher=[[EMAP]] | date=March 1984 | url=https://archive.org/stream/sinclair-user-magazine-024/SinclairUser_024_Mar_1984#page/n53/mode/2up }}</ref> The game was also able to run on the 16K version of the Spectrum.<ref name=best/>
