Now you know all the roulette bets and how much you can win with each one. So we come to the most interesting part of the article. It is time to calculate the roulette odds and find out the long-term value of each roulette bet.
I have calculated the RTP (player win) for each of the bets listed in the tables below. This is what we call the payout ratio. The payout ratio is the long-term expected value of a bet. You can dig deeper into the topic in my article on RTP and variance.
Inside bets: odds
Some of these bets are only available in the American or European versions of the game, so some cells are empty.
Note that the RTP of the “top line” bet in American roulette is lower than the RTP of any other roulette bet. This is because this bet covers five numbers and only pays the value of the bet x7. If the winnings of this bet were 7.2 times the bet, it would have the same RTP as the other bets of American roulette. So it is not a good idea to put chips on the “top line” bet.
Advertised bets: odds
The advertised bets are special. These are smaller bets that cover various sectors of the roulette table. This means that the odds of the advertised bets can be divided into the odds of the individual smaller bets.
Therefore, I will not include the RTP of these bets as I have for standard internal and external bets. Every advertised bet made on a zero roulette has an RTP of 97.3%. The advertised bets I have mentioned in this article are internal bets, which means that the RTP of the total bet cannot be influenced by the special roulette rules that change the RTP of the balanced probability bets.
Advertised bets are used almost exclusively in European (French) roulette. However, if they were used (with some modification) in American roulette, they would have an RTP of 94.74%, unless they contained the “top line” bet, which has a different RTP and would slightly change the RTP of the total bet.
These are the bets and rules that can change the advantage of the casino house:
- The “Surrender” rule reduces the house edge in double zero roulette for balanced probability bets (red/black, odd / even, high/low) to approximately 2.6%.
- The “top line” bet covering the numbers 0, 00, 1, 2, and 3 on a double zero roulette has the highest house edge on a roulette table: 7.9%.
The smaller the house edge, the better for the players. From the point of view of the RTP and the house edge, the balanced probability bets of French roulette, either with “La Partage” or “En Prison,” are the most advantageous for players, since statistically only they will lose 1.35% of the number of their bets.
