Mondo Solitaire is an application that provides you with dozens of solitaire games. You can enjoy playing these brain teasing games while on a break from work or just to test your solitaire capabilities.
The interface is simple yet interactive, with nice 3D effects. For every type of solitaire game this application has to offer, you have access to detailed information regarding the gameplay and plenty of useful hints with recommended moves.
There's also a cheat feature available for being used in order take a peek at the hidden cards (view the next cards in line) and calculate your next card moves.
The only thing I don't like about using this program is that it doesn't allow you to save the game progress.
As for the rest, the application works fine; it brings you a wide range of solitaire card games, plenty of useful hints and the undo action can be performed as often as you want.
If I have to summarize, my honest belief is that it's worth acquiring Mondo Solitaire, despite its singular disadvantage. I find this application a great solution for testing solitaire skills and, at the same time, for relaxing while on a break.
