Freehand Solitaire lets you play the Klondike card game on your computer and comes in handy when you're on a short break from work. Your goal is to move all cards to the four slots from the upper side of the screen, in ascending order from Ace to King.
The quicker you arrange your cards accordingly on the four slots, the higher your score gets. Though, the app doesn't keep track of your highest scores.
Personally, I'm not very keen on the layout of this game. I say this because I'm used to playing Solitaire games that display the card sets horizontally (easier to see the card's value) and this app shows them vertically.
Another thing I don't like is the fact that the app doesn't let you choose from different difficulty levels (only one difficulty level is available and this seems a bit too easy).
Briefly, I'd say it's worth installing this card game on your Mac as long as the aforementioned flaws don't mean much to you. The app is free of charge, so you have nothing to lose by trying it on your computer.
