This game was programmed by Thomas Weibel using DHTML and Javascript. The object of the game is to remove tiles that are “open” on the left and the right. Don’t worry, if you can’t see any open tiles, there is a “hint” button that may reveal moves that you did not see. There is also a “zoom” button if you find the tiles to be too small and is straining your eyes. Note that not all games can be won. However, good players can sometimes win one out of every three games.
