The House edge in the European Roulette
If you are a save player, then you know how important the knowledge of house advantage is. In both the American and European version of Roulette, the payout received for each bet is exactly the same. The extra 00 in the American Roulette is therefore another reason for you to lose more money in the American version of Roulette. For example, if you placed $10 on black and then $10 on red, this is pointless, but to prove a point let us just go with it.
The European Roulette wheel has black and red numbers, that is, 0-36. Very notable, is the fact that only one zero is present in this version of the Roulette game. In this version, the house edge is 2.7%. The house edge is brought down even further by the rules often found at the European roulette table – the La Partage and the En Prison rules – these bring down the house advantage to 1.37%.
Therefore, there is a 36/37 chance that you will get your $20 back if the ball lands on either red or black and a 1/37 chance that you will lose your $20 should the ball land on green, (0).
On the other hand, when we take a look at the American Roulette, there is an additional 00 to the single 0. There are also the same 36 red and black numbers, but instead of one green number, there are 2 of them. This means that there is a 2/38 chance of you losing your money. To a certain extent, your odds of losing money will almost double because of the extra 00.
