Snapper

As in Pac-Man, bonus items such as fruit sometimes appear in the center of the screen. The highest-scoring bonus item is an acorn, a reference to the publishers. When Snapper is killed, it shrinks and turns into small lines pointing in all directions.

The main difference in gameplay between Pac-Man and Snapper is the behavior of the ghosts (or monsters). In Pac-Man, each ghost has its own personality and follows set patterns for each level. The red ghost also travels at double speed after a certain number of dots are eaten. In Snapper, the monsters begin each level by patrolling their corners a set number of times before breaking from their route to chase the Snapper.

Snapper was published by Acornsoft. Acornsoft was the software division of Acorn Computers and was founded in 1980. Like many of the early games for the company, they Snapper was a video game clone of other arcade games. In the 1970s and early 1980s, video game clones of popular arcade games were rampant, and this growth of clones was followed on home computers. These clones often copied gameplay and had similar names to their original influences.

Two versions of Snapper were made. Prior to the version made by Jonathan Griffiths, there was one written by Hugo Tyson for the Acorn Atom. The later version of Snapper was coded by Griffiths who was working for the game's publisher Acornsoft, a company he joined in September 1981.

John Vaux in Acorn User reviewed three maze games: Bridgeman, Munchyman and Snapper saying that the latter title was "certainly the best on all counts." Vaux complimented that the characters move smoothly and at good speed and that "was more to the game" in Snapper than the other titles.

From retrospective reviews, Peter Connors of Personal Computer Games described it as "the best BBC version of that all-time classic Pac-Man." Darran Jones of Retro Gamer described Snapper as being an excellent maze game that played as good as it looks while saying its repetitive gameplay won't be for everyone. Jones also complimented the fast-paced and the game's tight controls. Griffiths attributed these qualities to programming the games to making it in machine code which led to benefits in speed and memory efficiency.
