This program gives you access to a few Solitaire game variations which you can play on your Mac computer while you're on a break from work. Card Shark Solitaire supports unlimited undo actions, provides you with various display and sound options, and gives you access to detailed game instructions.
You can choose from games like Klondike, Freecell, Spider Solitaire, Draw Poker, and many others. The program gives you access to the correspondent set of rules of each type of card game, lets you select the preferred board background and deck style, and brings you an option which, if enabled, counts the amount of time you spend completing a level.
I like the fact that the program automatically saves your game progress. Hence, you can shut down the app when the work break is over and resume the gameplay whenever you like.
Another good aspect about this app is that you can play the card games in full-screen mode at the same graphics quality. Furthermore, you can configure the program to display the time on the upper-right side of the screen so you can know exactly how much time you got left from your work break (this option is useful when playing in full-screen mode).
To conclude, I'd say it's worth installing this game on your Mac computer. The app brings nicely drawn graphics, provides you with a detailed statistics report, lets you choose from various card game types, and comes without a price tag.
