What's the biggest PC time-waster of all time? It might be solitaire; countless hours have been whiled away while people play solitaire on their PC. The next time you're on an airplane, or in a meeting for that matter, and see someone engrossed in their PC, snatch a peek at their screen. Don't be surprised if solitaire, not spreadsheets, is what's on the screen. It may even be Solitaire 3D, a three-dimensional variant of the classic--and a freebie to boot.

With this game, you get a set of very nice 3D games that are handsome looking, and feature good sound effects and animation. There are the usual solitaire variants, such as Klondike and Spider, but there are others you most likely don't know, such as Beleaguered Castle. Solitaire 3D comes with a half dozen free games; if you want to play the main other versions, you'll have to upgrade to a for-pay version.
