AlterJig is a set of tile-based jigsaw games and puzzles. You select
graphics supplied with the games or create your own puzzles from
any bitmaps. When you select "new game", it scrambles the puzzles
and challenges you to restore the pictures by rotating groups of four
tiles to get the tiles back to their proper positions. Tile rotation is
controlled by left and right mouse buttons. It sounds easier to solve
than it is.
