Roulette Odds

Although roulette is one of those casino games that is hard to beat in 2023, no matter what betting strategy you use, it's still worth learning online roulette odds.

With even a basic grasp of the odds for online roulette on the web, you can pick a betting game that's right for you.

On this page we describe the various odds available on a roulette wheel and show you how to calculate odds for online roulette games.

Roulette Odds Explained: House Edge

You might be wondering how the casino can pay 1-1 on your money, yet you only stand to win 48.65% or 47.37% of the time on a wager on Red, Black, Odd or Even. The answer is simple:

It's the zeros.

Web roulette players aren't paid when the ball lands on zero (unless they bet on the number, of course), so that's what gives the house their edge: a 5.26% edge for double zero roulette and a 2.7% edge in single zero roulette, to be exact.

Knowing this, it should now be clear that you should avoid (American) double zero roulette games when possible since the online roulette odds house edge is nearly double.

It doesn't look like much of a difference, but it's an extra $3 loss for every $100 in your bankroll. That adds up over time, and it could have been used for extra play time or working through a welcome bonus. So, all things considered the compounded loss is greater than $3.

Roulette Odds Explained: Outside Bets

Money notes and coins

It should be clear that looking at online roulette odds, your outside bets are going to be the most profitable ones. You're essentially flipping a coin on any color or even/odd bet.

To put this into perspective, compare the loss you take when you wager $5 on red versus $5 on a single number:

(5 (.4865*2)) -5 = -$0.135

(5 (.270*2)) -5 = -$4.75

Betting on red in a single zero game will see you lose a little over 13 cents. This is peanuts when compared to the $4.75 loss you take every time you wager on an individual number.

So, if you're looking for a mild way to spend your afternoon, and want to prolong your roll for as long as possible, it's clear that wagers on Red, Black, Odd, Even, 1 to 18 and 19 to 36 are the way to go.

How are roulette odds worked out? 

Roulette odds are worked on the probability of your predicted outcome being correct out of all possible outcomes on the wheel.

What variations offer the best odds of winning? 

European and French-style roulette offer better odds of winning than American roulette. The former two use only one zero, while the later has a single and a double zero on the wheel.

How can I maximize my odds? 

You can maximise your odds by betting on different colours (red or black), different number types (odd or even), or even whole columns and sections of numbers on the table.

Are they better or worse than other casino games? 

Roulette is a game of pure luck, like slots, so the chances of winning are less than skill-based games like poker irrespective of your level of experience. However, roulette offers you better odds of winning than other chance-based lotteries and number games.

Is the online game fixed? 

Absolutely not. Online games produce random outcomes thanks to special software which ensures true randomness. Reputable casinos offer to have their games monitored regularly by independent watchdogs like eCOGRA that check for randomness and fairness, and publish the results obtained.
