As much as casino players like French Roulette, casino operators dislike it. A lot of big casinos don’t offer French Roulette at all, while offering American and European Roulette. If French Roulette is in the offer, it’s usually only one game without any different variants, unlike the other two versions. That’s because of the house edge and average returns.
House edge is the percentage of every wager expected to be retained by the casino in the long run. The higher it is, the better for the casino. In American Roulette it’s 5.26%, in European Roulette it’s 2.70% and in French Roulette it’s 1.35% on even money bets and 2.70% otherwise.
1.35% house edge is considered too low by casinos. However, they also offer games with house edge under 1%, such as variants of video poker and blackjack. The difference comes from the fact that roulette will only ever be a game of chance, so in the long run it’s simply impossible for the casino to make over $1.35 for each $100 wagered on even money bets.
Blackjack and video poker are based on luck and skills. If the house edge is 0.5%, the players who have perfect skills will get an average return of 99.5%. But most players don’t have perfect skills. The average return goes down for players with lower level of skills, sometimes below 90%. Blackjack, grouped with other table games, has average returns about 97%. That’s why French Roulette is frowned upon by casinos even though in theory its house edge is higher.
