Enigma is an addictive little KDE game. It's a block moving puzzle game. You have to remove all the playing blocks on each level by touching blocks with the same picture together. Sounds simple, doesn't it?
At first, all you have to contend with is gravity, but soon you'll find all sorts of hazards and puzzles will make your task more challenging.
This is a port of an original commerical Acorn RISC OS game I wrote in 1992.
It runs under KDE 3.x and also under KDE 2.x.
