Mystic Square plays like a fairly typical vertically-scrolling. This slide puzzle game is for those who get an adrenaline rush playing tic-tac-toe and want to tone it down a bit. The goal of the game is to slide the randomly placed tiles, numbered 1 thru 15, into numeric order without falling asleep. If you need to take a tranquilizer when playing crossword puzzles, then this game is for you.
