Solitaire or patience is a card game which one can play by oneself.
Most solitaire games function as a puzzle which, due to a different starting position, may (or may not) be solved in a different fashion each time.

The first collection of solitaire card games in the English language is attributed to Lady Adelaide Cadogan through her Illustrated Games of Patience, published in about 1870 and reprinted several times.
