Belle, Flux et Trente-et-Un, is an historical, gambling card game that was widespread in France and Germany during the 17th and 18th centuries.
As a relative of Brag and Poch, from which the game of Poker developed, it is of cultural-historical interest.
The player who has the highest upcard, the so-called Belle, wins the first deal and the contents of the first basket.
[2] Unlike the game of Poch, there is no betting on the highest combination, as subsequently became typical for Poker.
[2] The modern casino game of Black Jack was developed from this contract via Trente-et-Un and Vingt-et-Un.
