AbcPuzzles offers two variations on a tile-based puzzle game. Each uses the same basic engine, in which you move the tiles in groups of four or more by spinning them with the control located in the corner where four tiles touch. Much like Rubik`s Cube in two dimensions, the games are harder than they first look since you must get the tiles properly aligned without disrupting your previous work. AlterJig uses images, scrambling the inner blocks but leaving the outside one intact.
