Trente et Quarante (Thirty and Forty), also called Rouge et Noir (Red and Black), is a 17th-century gambling card game of French origin played with cards and a special table. It is rarely found in US casinos, but still very popular in Continental Europe casinos, and one of the two games played in the gambling rooms at Monte Carlo, roulette being the other. It is a simple game that usually gives the players a very good expected return of more than 98%.
