Chuckie Egg is a home computer video game released in 1983. The original idea is generally attributed to the then 16- or 17-year-old Nigel Alderton. After a month or two of development, Nigel took a pre-release version of his Spectrum code to the two-year-old software company A&F, co-founded by Doug Anderson and Mike Fitzgerald (the "A" and "F", respectively). Doug took on the simultaneous development of the BBC Micro version, whilst Mike Webb, an A&F employee, completed the Dragon port. Chuckie Egg went on to sell over a million copies and remained a steady earner for A&F, who eventually went under in the latter half of the 1980s.

The versions fall broadly into two groups — those with realistic physics (e.g. the BBC Micro and Amstrad CPC versions) and those without (e.g. the ZX Spectrum version). Although there is a substantial difference in play between the two, levels remain largely the same and all the 8-bit versions have been cited as classics.
