Solitile is a game of solitaire, played with "tiles." The goal of the game is to remove pairs of matched tiles until all tiles have been removed. The game derives from several similar games, such as "Shanghai," "Gunshy," and "Mahjongg," which are played with Mah-Jong tiles. Solitile plays the same game but adds new starting layouts (16 included) and new tile sets (4 included). Its default tile set uses "westernized" pictures on the faces of the tiles, but can also use any of three alternate tile sets. This version includes 5 regular puzzles and 5 more difficult puzzles in each layout, 160 puzzles in all.
