Solitaire is a group of card games that are played by one player. Most solitaire games use one pack of playing cards. In many countries (for example, UK), solitaire is called Patience.
There are many types of solitaire. Some of these are Klondike, FreeCell, Pyramid, Golf, and Spider. Some computer operating systems come with simple video games that copy the gameplay of solitaire games. For example, there is a Spider Solitaire game on Microsoft Windows.
In Klondike, the player wins the game when the player has all the cards in four stacks organized by color ("suit") and number.
