Roulette odds are important and if you want to know what bets the highest chance and probability of landing on the wheel have, you will probably want to stick around and read on. Listen, calculating odds is not really that difficult. All you need to do is reference our tool and tables found below or even calculate the odds for yourself. We have made this process simple by featuring a couple of great examples to catch you right up to speed. Let’s get started.
How to Calculate Roulette Odds?
If you are wondering how to actually do the math yourself – don’t worry. It’s super easy. What you do is you take the numbers covered by your bet and then you divide them by the total numbers of the roulette wheel – 37 for European roulette and 38 for American roulette. There are other variants with more and less numbers too. Lastly, you multiply by 100. Let’s take a look at how this works.
- If you play European roulette, there are 37 numbers on the wheel, i.e. 0-36
- You then make a straight bet and divide 1/37
- The resulting number (0.0270) is then multiplied by 100
- This means you have a 2.70% to hit a straight bet on European roulette
As you can see, the math is pretty straightforward. However, it will change depending on the type of wager you use. Even Money bets, such as Red/Black will result in an 18/37*100 or 48.64% probability of success.
Please keep in mind that the total numbers in a version of the game will have a say in what the actual probability is so don’t forget to factor them in.
Odds = Number of occupied field Number of overall fields x 100%
Number of overall fields = 36 for single zero roulette
Number of overall fields = 37 for single double zero
