Solitile is a game of solitaire, played with "tiles".  It derives from several similar games, such as "Shanghai" 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 also uses new, "westernized" pictures on the faces of the tiles.
