It is hard to imagine why some consider Trente et Quarante a complicated game, when it is on the contrary as straightforward as it is ancient.
There are only four chances at Trente et Quarante: red, black, colour, inverse.
The croupier deals out two separate rows of cards (red and black), sequentially. After each row totals greater than 30, the hand is settled; all face cards are counted as 10. The winning total will range between 30 and 40 card points, which is from where the name of the game derives. If this should be also the color of the winning row, the player wins. The ‘color’ wager is a type of bet that the first card of the row that wins will be the same color as the winning row. The ‘inverse’ wager is the opposite of the ‘color’ wager.
It is a bet that first card of the winning row will be the opposite color of the winning row. Bets are payed even. However, when the same number for each row is 31, the croupier announces ‘un après’ and either the house blocks all bets or takes half of all. This represents the house advantage.
