Vingt-et-Un

Chambers's Encyclopaedia, Volume 10: Swastika to Zyrianovsk and Index, p. 486

Vingt-et-Un, a game of cards, the aim in which is to get as near as possible to the value of twenty-one (hence the name) without exceeding it. The game is played with the whole pack, the ordinary cards being reckoned according to the number of pips on them, while the court-cards are ten, and the ace is one or eleven, as the holder may elect.
