Chuckie Egg

A&F Software's Chuckie Egg is a home computer video game released in 1983, initially for the ZX Spectrum, the BBC Micro and the Dragon. Its subsequent popularity saw it released over the following years on a wide variety of computers, including the Commodore 64, Acorn Electron, MSX, Tatung Einstein, Amstrad CPC and Atari 8-bit family. It was later updated and released for the Amiga, Atari ST, and IBM PC..

The game was written by Nigel Alderton, then 16 or 17 years old. 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.
