Jpuzzle (Ver. 1.1) is a windows puzzle game which lets you read in any .BMP file, scramble it into from 4 to 400 pieces and put it back together. There are two different modes (and therefore games) for moving pieces in Jpuzzle, one is called Jigsaw and the other Sliding. With jigsaw you select two pieces and exchange their positions, with Sliding there is one empty position into which adjacent pieces can be moved to.
