Long term probabilities do not influence the outcome of any single spin.Understanding the Probabilitiesīefore we start with the numbers, it’s important to understand one thing in particular. Obviously though, if you played American Roulette for example then the odds would change. We will also apply everything to European roulette rather than any other variation as that is the most common version of the game played in the UK. If you are interested in the probabilities of single number bets, then have a look at this article as well. This article is going to focus on the even money bets, and will refer mainly to red and black, but the information will also be true to the other 1:1 bets such as odd or even, and high or low (1-18 and 19-36). Understanding the game allows players to make sensible decisions that are not influenced by psychological biases, and means you can also employ any staking strategy you may be using without diverting to something else based on perceived ‘patterns’ or a hunch.
However, that doesn’t mean that understanding and learning about the odds and probabilities of the various different bet types is a waste of time. People are always looking for ways to find an edge with roulette, despite the fact that it is a totally balanced game with a set house edge that cannot be ‘beaten’.
