Roulette Odds
Learn roulette odds today and make smarter bets!
The first thing to say about any roulette game, is the odds are pretty long compared to other casino games. If you’re looking for a fairly slow-paced, low on rules and easy-to-understand game, and are prepared to give the house a little more edge in return, then roulette is the game for you. If you’re after a really decent return and a more interesting game, have a look at some of our other games. So let’s take a look at the odds you are facing as a Castle Casino live casino player. These differ between the American and European versions, so let us examine them both in turn.
European Roulette Odds
Here at Castle Casino, our unique live roulette games operate under the European system. European roulette is played on a single wheel. It features the “en prison” rule, which is particularly favourable to the player. The “en prison” rule works by awarding the player half their stake back when they make an even money bet and the ball lands on zero. Alternatively, the bet can be “imprisoned”, whereby it’s held over until the next bet. If the following spin wins, then the player can get their original bet back (sans winnings, au naturellement!).

American Roulette
Although not a live game, here at Castle Casino we do run a superior version of American Roulette, so let’s see what the odds are like… An American wheel comprises 38 numbered slots – numbers 1-36, a zero, and a double zero. You can place bets on all the individual numbers and a range of outside-bet combinations of numbers. Apart from Atlantic City, all American gambling cities observe the following table of win probabilities and House Edge.
