# How Does House Edge in French Roulette Work?

House edge is essentially how all casinos and roulette online casinos earn from their players. It is a small percentage of money that they take overall in all games. They usually secure their house edge by the rules in the game, and today we are going to explore how rules of French Roulette affect the house edge and help casinos earn money.

You should take into account that house edge exists in all casino games, and that roulette usually has a low edge, especially the French one. First of all, we are going to give you just a small tease that may make you think twice about the payment system of this game: there are 37 possible winning numbers, yet the payout is usually 35 to 1 for a single-number bet.

Therefore, we should break things down to math. The probability for you to succeed is 1/37 for a single number bet, so the only logical thing is to think that you need to be paid 37x your bet, but you get paid 35x. If we take into account that you also get your bet back, you basically get 36x your bet. Therefore the difference between the total number of fields which is 37 and your bet payment, which is 36, is the house edge that casino earns from you.

In fact, this can be summed in a simple equation 1x 1/37 = 0.0270. This number is usually multiplied by 100 in order to get the exact percentage of the house edge, and it rounds up to 2.70%.

Therefore, for every \$100, the casino will earn \$2.70. Now, we all know that luck works in mysterious ways, so sometimes casinos earn much more than that if players aren’t lucky. Sometimes, they don’t earn as much if luck favors the players. However, when you step back and look at the big picture, you will notice that it all ends up to the 2.70% that we previously calculated – it’s simple math.

However, we advise you not to pay too much attention to math and focus on having fun, because, after all, roulette is a game and games are supposed to be fun.
