What Are Roulette Odds: A Guide to Probability and More in 2024

Gambling odds are vital if you’re set on maximising your profits while playing at a land-based or online casino. Regardless of which one you’re playing, the odds will remain similar or the same. Welcome back to the site, in case you forgot, I’m Sensei Joe, your honorary Japanese gaming expert and master swordsman.  

Here we’ll be taking a look at roulette odds and how each bet has a better chance of resulting in a win and a loss. By the end of this segment, you should have a good understanding of roulette payouts. And the good news is that you’ll never have to ask what roulette odds are ever again.  

What are Roulette Odds?

Every game of chance has odds, whether it’s rock, paper, scissors or blackjack, and online roulette features odds too. Fear not, you won’t need to bust out your calculator for this one, as I’ll do the maths for you – did I mention that I’m great at maths? So, if you’re making a straight-up bet in roulette, you’ll easily be able to identify the roulette table odds for that particular bet. This is because there are 37 possibilities from one bet. So, it would be 37:1 – 38:1 if you’re playing American roulette, as there’s a double zero.  

But, keep in mind that the casino only pays out 35:1 on successful bets. The same roulette odds are applied to some combination bets. If you’d like to know more about odds on a roulette table while learning how to calculate roulette payouts, then check out my sweet table below.

Five Numbers Any of 0, 00, 1, 2 or 3  13.2% 13.5% 6:1 
Four Numbers Any of 5, 6, 8 or 9 10.5%  10.8% 8:1 
Three Numbers Any of 28, 29 or 30 7.9% 8.1% 11:1 
Two Numbers Either 19 or 20 5.3% 5.4% 17:1 
One Number 7  2.60% 2.70% 35:1 
Even Bets Black over Red 47.4% 48.60% 1:1 
Dozen Any of 13 to 24 31.6% 32.40% 2:1 
Column Any number in the third column 31.6% 32.40% 2:1 

If you’d like to take on the maths by yourself, then all you need to do is divide 36 by the number of slots that you bet on then subtract 1 to get your payout odds.

The Best Way to Improve Your Odds

While you could have a complete understanding of a roulette payouts calculator or simply know your way around the table when it comes to your bets. This counts for nothing if you’re making bad decisions. Sticking to the basics and using a concrete roulette strategy is the best way to kick things off. Ignore what you usually see other players doing and stick to your strategy. Another easy way to have better odds is to avoid American roulette tables. As the double-zero slot increases the house edge – which isn’t going to help you. 

Common sense goes a long way in roulette and starting with the lowest bet. Slowly working your way towards higher bets will come in handy when playing European roulette. This is because the minimum bet is generally around $25. Betting on ranges instead of individual numbers is also the best way to make your money go further. The same applies to betting on black or red.  


The odds of any casino game are very important and the same applies to roulette. Here I’ve given you the fundamental rundown of everything that you’ll need to know about betting. You also have payout odds with a bit of extra information in between. Nevertheless, once you start using this information to your advantage, you’ll quickly see a difference in the outcome of your games. But don’t forget, you’ll need to practice your strategy at free play online casinos and a bit of luck will also be needed. 


What are the best odds in roulette, and how can I make sure that I get them? 

If you’re looking for the best odds, outside bets are going to be your best friend. Place bets on odd or even, black or red, or ranges from 1 to 18 or 19 to 36. All of these will have a payout of 1:1, which is what you’d want. 

What are the roulette odds of black or red being hit in roulette? 

There’s no way of determining which will hit more, as there are an equal number of black and red slots on a roulette wheel. So, the odds are always going to be equal unless you create a custom wheel that consists of more red or more black slots.
