Games of patience, or (card) solitaires as they are usually called in North America, have their own 'language' of specialised terms such as "building down", "packing", "foundations", "talon" and "tableau". Once learnt they are helpful in describing, succinctly and accurately, how the games are played. Patience games are usually for a single player, although a small number have been designed for two and, in rare cases, three or even four players. They are games of skill or chance or a combination of the two. There are three classes of patience grouped by object.

Patience (Europe), card solitaire or solitaire (US/Canada), is a genre of card games whose common feature is that the aim is to arrange the cards in some systematic order or, in a few cases, to pair them off in order to discard them. Most are intended for play by a single player, but there are also "excellent games of patience for two or more players".
