Solitaire is one of the most well-known and most played computer games ever. Solitaire games (also referred to as patience games) are card games for one person, played with regular playing cards. Over 500 different solitaire variants exist, each having unique rules and using different fields. These fields can include the tableau where the majority of the gameplay happens, the foundation, the stock, the waste pile, the free cells, and the reserve.
The most well-known solitaire games are Klondike Solitaire, FreeCell, Spider Solitaire, and Pyramid Solitaire. But the other solitaire variants are also fun to play and can be learned easily because they are all based on the same principles.
