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. 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. 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 Famicom, later predicting that the ZX Spectrum had a limited lifespan.
