Chuckie Egg

Chuckie Egg is a video game released by A&F Software in 1983 initially for the ZX Spectrum, BBC Micro, and Dragon 32/64. Its popularity saw it released over the following years for the Commodore 64, Acorn Electron, MSX, Tatung Einstein, Amstrad CPC and Atari 8-bit family. It was later updated for the Amiga, Atari ST, and IBM PC compatibles.

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 before the company went into administration in the late 1980s.

The versions fall broadly into two groups: those with realistic physics (e.g., BBC Micro and Amstrad CPC) and those without (e.g., ZX Spectrum). 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.

As Hen-House Harry, the player must collect the twelve eggs positioned in each level, before a countdown timer reaches zero. In addition there are piles of seed which may be collected to increase points and stop the countdown timer for a while, but will otherwise be eaten by hens that patrol the level, causing them to pause. If the player touches a hen or falls through a gap in the bottom of the level, he loses a life. Each level is made of solid platforms, ladders and occasionally lift platforms that constantly move upwards but upon leaving the top of the screen will reappear at the bottom. Hitting the top of the screen while on one of these lifts, however, will also cause the player to lose a life.

Eight levels are defined and are played initially under the watch of a giant caged duck. Upon completion of all eight the levels are played again without hens, but Harry is now pursued by the freed duck flying around the screen and homing in on him. A second completion of all eight levels yields a third play through with both hens and the duck. A fourth pass introduces additional hens. Finally, a fifth pass has the duck and additional hens moving at a greater speed. If the player completes all forty levels then they advance to 'level 41' which is in fact exactly the same as level 33.

The player starts with five lives, and an extra life is awarded every 10,000 points.
