Solitaire
Solitaire (aka Klondike aka Patience) can be played here with TGS themed cards. Currently only the web version is available. Downloadable versions for Windows and Linux will follow. The game, while very much playable, still has a few known issues/limitations.
At present you cannot drag cards from discard pile back down into playing field. There are no sounds. There is no satisfying victory animation when you succeed. And there are no rules settings
(you can only draw single cards and go through the deck an unlimited number of times).
And there is this weird bug that will sometimes makes the top card of the deck rotate seemingly randomly when you draw a card.
