Solitaire

Solitaire is a card game for one player using a pack of playing cards. A player wins the game when the player has all the cards in four stacks organized by color ("suit") and number.

There are many types of solitaire, such as Klondike, Freecell, Pyramid, Golf and Spider. Most computer operating systems include simple solitaire games.

In many countries (for example, UK), solitaire is called Patience.
