Mondo Solitaire from Ambrosia Software packs over 100 solitaire card games into one software application, easily earning the name 'Mondo.' You will find not only the expected games, such as Klondike, Canfield, Freecell, and Gold, but also the unexpected, such as Streets and Alleys, Trefoil, and Yukon.

Each game includes a brief description that will get you started, even if you have never played the game before. Additionally, many games offer multiple playing options, including the type and number of decks to use.

Besides customizing game play, you can customize the playing surface, deck backs, and card faces. And when you're just not sure which game you want to play, Mondo Solitaire can pick one at random for you.

If you find yourself with a bit of time on your hands, Mondo Solitaire can keep you busy, at least until your boss walks by.

Mondo Solitaire is $9.99. A 30-day demo is available.
