Roulette Odds: All Useful Data

Roulette is one of the easiest games to start playing, but understanding your odds can make a big difference. Below, we walk through the most common roulette bets and explain how each one pays – from simple even-money wagers to high-risk single number bets. We also share a couple of great places where you can try these bets online.

Red/Black – 1:1 (47.37%)

The colour bet is a popular wager with chances of 1:1. Let’s say you bet C$5 on red, and the ball falls on red after the wheel is spun. You will receive C$5 back in addition to C$5 in prizes, for a total of C$10.

In European roulette (single-zero), the probability improves slightly to 48.6% because there is only one green 0 instead of two green pockets (0 and 00) like in American roulette. This gives players a better chance of winning in the long run.

According to the 2024 Nevada Gaming Abstract, American roulette has an average house edge of 5.26%, while European roulette maintains a 2.7% edge – giving European roulette players almost twice the long-term advantage.

Pair / Impair – 1:1 (47.37%)

The odd and even boxes, like the colour bet, offer the same payoff with the same roulette odds whether you hit even, odd, red, or black. The green ‘0’, however, does not qualify as even or odd.

Tip: Since zeros are not odd or even, your true odds in roulette on these bets are slightly under 50%, meaning the house still keeps its small but steady advantage.

19-361-18 / 19-36 – 1:1 (47.37%)

These bets divide the table in half, allowing you to wager on the lower half of the numbers (1-18) and the upper half of the higher numbers with one bet (19-36). ‘Miss’ and ‘Pass’ are other terms for the same thing.

Discussion: On Reddit (r/roulette), multiple players confirmed that long-term simulations of 1:1 bet still result in steady losses over time, no matter what “system” is used – perfectly aligning with the mathematical expectations of game odds.

Dozen – 2:1 (31.58%)

The Dozen bet allows the player to wager on three separate games involving 12 numbers: 1-12, 13-27, and 28-36. Even though this wager has somewhat better odds (2:1) than even money, the chances of winning on a roll are slightly lower.

In a Reddit discussion (r/gambling), user BeautifulSundae6988 tried betting on “thirds” but still busted across multiple simulations, showing that covering two-thirds of the table doesn’t beat the odds in roulette when the payout structure and zeros are factored in.

Row Bet Column – 2:1 (31.58%)

The column bet is similar to the dozens bet, but instead of dividing the table into three pieces widthwise, it splits it into three sections lengthwise. Like the Dozen Bet, each of these bets has improved 2:1 odds.

Strategy Tip: Betting on columns can be fun, but remember – your win rate is roughly 31.6% on an American wheel and slightly better on a European table, based on standard roulette table odds.

6 Number Bet – 5:1 (15.79%)

This form of wager isn’t always offered at online casinos, although it may be found in the majority of them. This bet, which is sometimes ignored by new players, allows you to gamble on six numbers at once by placing a bet on two adjacent rows.

In French roulette, this is called a “sixain” bet – another way to stretch your bets across more numbers without betting too large amounts.

4 Number Bet – 8:1 (10.53%)

The 4 Number Bet, sometimes known as the ‘Square’ bet, allows you to wager on four neighbouring numbers at once. Although the chances of striking any of these numbers are slim, the winnings are substantial when luck is on your side.

User kbrawlz on Reddit (r/roulette) shared that even when covering most of the board, the ball tended to find uncovered sections or zero, showing that even wide coverage doesn’t change the built-in advantage.

3 Number Bet – 11:1 (7.89%)

The chip is put at the edge of one of the rows, rather than at the margins of two rows, as in the 6 Number Bet. A “Cross Bet” is the name for this type of wager.

Also known as a “street” bet, and it can be an exciting mid-risk play for players aiming to maximize payouts without risking as much as straight bets.

2 Number Bet – 17:1 (5.26%)

It’s at this point that the odds start to matter. A 2 Number Bet, also known as a Horse Bet, lets you place a wager on two adjacent numbers, with odds of 17:1 – the second-highest payoff at the roulette wheel.

User Yonak237, a professional scraper on Reddit (r/roulette), showed that extensive live game tracking confirmed house edges remained intact even across thousands of spins. No method reliably overcame the built-in house edge.

Single Number Bet – 35:1 (2.63%)

The Single Number Stake, sometimes known as the “Full” bet, is the most popular at the roulette wheel, with chances of 35:1. Simply place your wager on a number and pray for the best.
