Though many people claim Linux is not for games or whatever, I really love the huge collection of those small games one can spend days on like logic, puzzle, simple strategies and others.
Recently I came across PySol FC Edition – a collection of more than 1000 solitaire card games. Short description from their website states:
There are games that use the 52 card International Pattern deck, games for the 78 card Tarock deck, eight and ten suit Ganjifa games, Hanafuda games, Matrix games, Mahjongg games, and games for an original hexadecimal-based deck.
Has everything from simple and known card games like FreeCell, Spider and Klondike to all kinds of weird things that take some time figure out on how to play them. For the ones who like Klondike, for instance – try Varaha game from the collection. It is more complex and more fun.
Warning you before you downloaded and launched it – may take a lot of your time away from you and you won’t even notice that!
