Released in 2005 as part of a compilation CD, Copper Swapper is a puzzle game made for the Sega Dreamcast. It was developed by the indie game developers Atani Software, in cooperation with Team Screamcast. With primary inspiration coming from other mini-games designed for Flash - such as BeJeweled and ZooKeeper – Copper Swapper features original gameplay, design, and strategies. The main character of the game is Swapper, a cartoon goat designed by indie game programmer Jeff Minter.
Swapper also serves as the mascot for The GOAT Store. The first version of Copper Swapper was originally submitted as part of The GOAT Store contest and after an initial release as freeware, it was included on the compilation CD for the Sega Dreamcast. Atani Software later released an updated version of the game. This updated version – Copper Swapper Version 0.53 – fixes a major bug found in the original game.
Other than that, the updated version is the same as the original: the player aligns colored tiles by moving and revolving them. Once the tiles are aligned, the alignments are removed, and the player scores points.
