Description: Solitaire, also called patience, often refers to single-player card games involving a layout of cards with a goal of sorting them in some manner. However it is possible to play the same games competitively (often a head to head race) and cooperatively. The term solitaire is also used for single-player games of concentration and skill using a set layout of tiles, pegs or stones rather than cards. These games include Peg solitaire and Shanghai solitaire.
