Solitile is a game of solitaire, played with "tiles". It derives from several similar games, such "Shanghai", "Gunshy", and "Mahjongg", which are played with Mah-Jong tiles. Solitile plays the same game, but adds new starting layouts and the ability for the player to create new layouts and/or modify the layouts provided. It has, built-in, "westernized" pictures on the faces of the tiles, and can also use alternate tile-sets, and the program includes a tile editor so that the user may alter existing tile pictures or create entirely new sets.
