Solitaire is a card game that dates back to the mid-18th century and goes under several different names throughout the world. It is known as patience in England and parts of the United States.
Solitaire typically involves drawing cards and attempting to play them into a certain arrangement. Players attempt to reorder the deck by rank and suit through a series of moves with predetermined restrictions. In the most common version of solitaire, players attempt to build four blocks of cards going from ace to king in each suit.
A wide variety of different rule sets exist for solitaire games, with varying levels of complexity and difficulty. Solitaire games can be played both cooperatively and competitively, typically as a head to head race.
