What are odds in roulette?

In roulette, odds represent the probability of a particular outcome occurring in one spin of the wheel. Odds are determined by the number of possible outcomes and the probability of each outcome occurring.

In a standard roulette game with a single zero, there are 37 possible outcomes: the ball landing on a number between 1 and 36 or the green zero pocket. The probability of any one of these numbers hitting in a single spin is 1 in 37 or as a percentage, 2.7%.

The odds in roulette can also be expressed as a fraction or a decimal. For example, the odds of hitting a single number in a single spin are 35 to 1, which can be written as 35/1 or 35.0. The odds of hitting a single number in two spins are 1,225 to 1, which can be written as 1,225/1 or 1,225.0.

The odds in roulette can vary depending on the type of bet you place. For example, the odds of hitting a single number in a single spin are higher than the odds of hitting a combination of numbers, such as a split bet or a corner bet. The odds of winning a bet on a single number are also higher than the odds of a bet on red or black, which have a probability of slightly less than 50%, being you can hit the zero (green) or double zero depending on the American or European version.

How to Calculate Roulette Payouts based on Odds

To calculate roulette payouts based on odds, you will need to first determine the odds of the bet that you want to place and the amount of your wager. Then, use the following formula to calculate the payout:

*Payout = (Odds * Wager) / (1 - Odds)*

If you want to calculate the payout for a bet on a single number in a standard roulette game with a single zero, you can use the following calculation:

Odds: 35 to 1

Wager: \$10
Payout: (\$10 * 35) / (1 - (35/36)) = \$350

Here is a breakdown of the payouts for some common roulette bets based on the odds:

• Single number (35 to 1): \$350 for a \$10 wager
• Split bet (17 to 1): \$170 for a \$10 wager
• Street bet (11 to 1): \$110 for a \$10 wager
• Corner bet (8 to 1): \$80 for a \$10 wager
• Line bet (5 to 1): \$50 for a \$10 wager
• Column bet (2 to 1): \$20 for a \$10 wager
• Dozen bet (2 to 1): \$20 for a \$10 wager
• Red or black (1 to 1): \$10 for a \$10 wagerIt is important to note that the payouts for roulette bets can vary depending on the specific rules of the game and the table you are using. Some roulette games may have slightly different odds or payouts for certain bets, so it is always a good idea to check the terms and conditions before placing a bet.

What are the odds for inside bets?

Inside bets in roulette are bets that are placed on specific numbers or combinations of numbers on the roulette table. They have a smaller chance of hitting than say, outside bets, but when they do, they pay handsomely. Here are the odds and payouts for some common inside bets in roulette:

Single number (35:1): The odds of hitting a single number in a single spin are 35 to 1. The payout for a single number bet is 35 times the wager.

Split bet (17:1): a bet on two adjacent numbers, such as 1/2 or 17/20. The odds of hitting a split 5.4% and pays 17x your wager.

Street bet (11:1): a bet on three numbers in a row, such as 4, 5, and 6 or 22, 23, and 24. You win if any of those numbers pops up in the spin. That’s 8.1%.

Corner bet (8:1): a bet on four numbers that form a square on the roulette table, such as 1, 2, 4, and 5 or 25, 26, 28, and 29 with odds of hitting at 10.8%.

Six line bet (5:1): a bet on two adjacent streets, such as 1, 2, 3, 4, 5, and 6 or 19, 20, 21, 22, 23, and 24. If you make a 6 line bet on European Roulette, it’s a 6:37 chance of winning (16.2%) and claiming a 5x your wager.

It is important to note that the odds and payouts for inside bets can vary depending on the specific rules of the roulette game you’re playing. Some roulette games may have slightly different odds or payouts for certain bets, so it is always a good idea to check in on these before placing your wager.

What are the odds for outside bets?

Off-grid is for outside bets. Most commonly, it’s red/ black, even/ odd, or high/low. Even though columns and dozens are number bets, they fall under outside bets as chips are placed along the perimeter.

Red/Black + Odd/Even + High/Low Bets (1:1):

The odds of hitting red or black in a single spin are slightly less than 50%, with a probability of slightly more than 48%. The payout for a red or black bet is even money.

Column bet (2:1):

With 36 numbers in play, a column bet allows you to choose a set of 12 numbers. You do the math - there’s three columns to choose from, each with 12 numbers of course. For example, 1-4-7-10-13-16-19-22-25-28-31 represents one column. Betting on one of these dozen numbers gives you a 1 in 3 shot (32.4%), and pays 2:1 on your wager.

Dozen bet (2:1):

A dozen bet covers, you guessed it, 12 numbers. It differs from a Column’s 12, as this dozen covers sequential sets. Dozen 1 covers 1-12, the second dozen covers 13-24, while the third dozen covers 25-36. A 1 in 3 shot (32.4%), and pays 2:1 on your wager.

What are the Odds for Special or Call Bets?

Special or call bets in roulette are bets that are placed on specific combinations of numbers on the roulette table. They’re common in French roulette and usually require a ‘call’ out to the Croupier for placement - which means, they’re more common in brick & mortar casinos, specifically on high roller tables. But we’re here to talk about their odds, so let’s get at’em.

Voisins du Zéro:
Voisins du Zéro or ‘neighbours of zero' covers the largest section of all the call bets - 17 numbers in total. Start at 22, work around the zero and end at 25 to cover this collection. A bet requires nine chips placed as follows: Numbers 0,2,3 as a basket bet (pays 11:1) + 4/7, 12/15, 18/21, 19/22, 32/35 as splits (pay 17:1) + a corner bet on 25/26/28/29 (pays 8:1). With 17 numbers covered, odds sit at 46%.

Tiers du cylindre:
Any French classes triggering translations yet? Tiers is ‘thirds of the wheel’ and covers ⅓ of the roulette wheel stretching along the opposite side of Voisins. Odds are 32.4% and it pays 17:1 as split bets are used to cover numbers: 5/ 8, 10/11, 13/16, 23/24, 27/30 and 33/36.

Orphelins:
This bet covers the ‘orphaned’ or leftover numbers not included in Voisons or Tiers. It’s an eight number bet requiring five chips in a mix of straight up and split bets on 17, 34, 6, 1, 20, 4, 31 (17:1 payout) and 9 (35:1 payday).

Finales en plein:
The finales en plein bet is placed on numbers that end in a specific digit, such as all numbers ending in 1 or all numbers ending in 9. The odds of hitting this bet in a single spin are 35 to 1 (straight bet odds 2.7%) and the payout is 35x the wager as it’s a straight up bet.

Finales a cheval (17:1):
The finales a cheval bet is a bet on the numbers that end in a specific two-digit combination, such as all the numbers ending in 1 and 6 or all the numbers ending in 8 and 9. The odds of hitting this bet in a single spin are 17 to 1, and the payout is 17 times the wager.

What are the odds of hitting green in roulette?

The American roulette wheel houses two green pockets, for a single and double zero, while the European wheel is home to only one single zero green pocket. As this means the American wheel has 38 pockets in total and the European only 37, the odds differ.

Odds of hitting Green in European Roulette - 2.7% (1 in 37)
