In 1993 Mario Leonti wrote a game called solitario. It is a simple fast and addictive game, very difficult to solve. In his holidays this year he revamped it for System X. We make you a gift of it. solitario is available only for Macintosh and I hope you find it as addictive as I do. Please do not hesitate to suggest beautiful additions to solitario and report bugs. To pause the credits in solitario's opening screen press the shift key, to backtrack hold down the option key. To start playing solitario click the mouse once. You are presented with a deck of cards. Click on the deck, press the enter or the return key to deal. If any two adjacent cards, or cards with not more than one card in between them, have the same value or belong to the same suit they can be both put on the same pile, you click them both and solitario will move the right hand card on top of the left hand one. You win if you can get all the cards in one pile. Mario decided to retain the vintage look and make solitario free, for the time being. All rights are reserved and you may use it but only at your own risk. solitario was tested on MAC OSX.3.6 to X.5.5 but it may work on earlier versions.
