Tesserae

This game is like pistachios for the mind—easy to get into, but hard to put down. The object is to remove tiles from the board by jumping over them, ending up with one remaining tile. The tile's movement is determined by the colors of the adjoining tiles.

You can play a Tournament or single-player game, choosing Easy, Medium or Hard levels (and believe us, Hard is hard). There follow nine stages of increasingly difficult game play. A reverse option lets you back up any number of moves. If you like tough addictive puzzle games, you'll love this one.
