Patience, or solitaire as it is known in the US and Canada, is a genre of card games that can be played by a single player. Patience games can also be played in a head-to-head fashion with the winner selected by a scoring scheme.
In the US, the term solitaire is often used specifically to refer to solitaire with cards, while in other countries solitaire specifically refers to peg solitaire. Both Solitaire and Patience are sometimes used to refer specifically to the Klondike form of Patience.
The purpose of patience generally involves manipulating a layout of cards with a goal of sorting them in some manner. It is possible to play the same games competitively (often a head to head race) and cooperatively.
Patience games typically involve dealing cards from a shuffled deck into a prescribed arrangement on a tabletop, from which the player attempts to reorder the deck by suit and rank through a series of moves transferring cards from one place to another under prescribed restrictions. Some games allow for the reshuffling of the deck(s), and/or the placement of cards into new or “empty” locations. In the most familiar, general form of Patience, the object of the game is to build up four blocks of cards going from ace to king in each suit, taking cards from the layout if they appear on the table.
There is a vast array of variations on the patience theme, using either one or more decks of cards, with rules of varying complexity and skill levels. Many of these have been converted to electronic form and are available as computer games. Examples of variants on the familiar Patience theme that may be played with an ordinary packet of cards include Bisley and Prince Albert. Basic forms of Klondike solitaire and FreeCell come with every current installation of Microsoft Windows, apart from Windows 8, wherein six unique card games can be downloaded for free in its app store in the form of the Collection.
