What are the Odds in Roulette?
Roulette odds serve as a reliable tool for assessing the likelihood of a desired outcome in various situations. In the context of roulette games, odds are determined by the number of slots on the table. For instance, in American roulette, where there are 38 slots, the odds of winning or losing are 1:37, with 37 representing the total number of possible ways to lose.
Before engaging in a game of roulette, it is essential for all players to familiarize themselves with the rules. Players are provided with coloured chips to place their bets on the table. The game begins as each player selects their bet, followed by the dealer spinning the wheel and releasing the ball. The pocket number where the ball eventually settles determines the winning number.
If a player's bet matches the winning number, they emerge as the winner, and the dealer proceeds to provide them with a payout based on the number of bets placed. Once the rules of roulette are understood, players can then consider employing different strategies to enhance their gameplay. A common strategy adopted by new players involves placing bets on outside bets, which have higher odds of winning despite offering lower payouts.
However, in order to overcome the odds and increase their chances of winning, more aggressive roulette strategies can be employed during play. For instance, the Adrucci strategy involves carefully observing the game and noting any numbers that appear more frequently than others during a series of spins. Players can then place their bets on these numbers, as they have a higher probability of winning.
How to Calculate Roulette Odds
Understanding the odds in roulette is crucial to improving your chances of winning, and they vary depending on the version of the game and the type of bet you place. When learning how to play roulette, having a basic understanding of the roulette odds is essential.
In roulette, you can place your bets on either inside or outside bets. Outside bets have statistically higher chances of winning, although the payouts are relatively lower compared to inside bets.
A simple calculation for odds involves dividing the probability of winning by the probability of losing. For example, if you bet on the colour red in European roulette, the probability of winning would be 18/35, as there are 18 red numbers out of a total of 35 possible outcomes.
The odds ratio determines the amount of money you receive as a payout after a win. In a standard scenario, the casino pays out winnings on a ratio of 1:36, reflecting the 36 slots on the wheel. However, casinos may adjust the rules to their advantage. For example, they might pay out on a 1:35 scale, keeping a 1% ratio difference as profit.
Suppose you placed a $1 bet and won. In this case, you would keep your initial $1 and receive an additional $35 as winnings. Each specific bet in roulette carries a different set of odds. For instance, in a split bet where you choose neighbouring numbers as your bets, the odds of winning on French roulette are 5.41%.
Examining Roulette Table Odds
Roulette offers two main categories of bets: outside bets and inside bets.
Outside Bets
Outside bets encompass wagers that do not focus on specific numbers but rather on larger groups of numbers. These groups are defined by the number, colour and even the position on the roulette table. These bets are called outside bets because you place your chips on the outer section of the table. Here is a quick explanation of what outside bets are:
Red or Black: You bet on whether the ball will land on a red or black number. There is a total of 18 red and 18 black numbers on the wheel.
Odd or Even: You can place a bet on whether the ball will land on an odd or even number. Landing on either of the zeros results in losing the bet.
Low or High: This bet involves predicting whether the ball will land on a low number (1-18) or a high number (19-36).
Dozens: You can place a wager of one of three groups of numbers: 1-12, 13-24, or 25-36.
Columns: Similar to dozens, this bet allows you to wager on one of the three vertical columns of numbers on the table.
Outside Bets: Odds on Roulette
The table below displays the payouts and odds for outside bets in both European and American roulette:
| Bet | Payout | European Roulette Odds | American Roulette Odds |
| Red/Black | 1:1 | 48.6% | 47.4% |

| Dozens | 2:1 | 32.4% | 31.6% |
| Columns | 2:1 | 32.4% | 31.6% |
Inside Bets
Inside bets involve placing chips on the inner section of the table and typically entail betting on one or a few specific numbers. These bets have lower odds of winning but offer higher payouts. Here are the different inside bets:
Straight: You wager on a single number on the roulette wheel and win if the ball lands on that precise number.
Split: This bet covers two adjacent numbers by placing your chips on the line between them.
Street: You bet on a row of three numbers, placing your chips at the end of the row.
Square (Corner): You must place a bet on the four numbers in a corner, covering all of them.
Six Line: This bet covers two adjacent rows of numbers, with chips placed at the intersection of the two rows.
Top Line: Only available in American roulette, this bet includes the numbers 0, 00, 1, 2, and 3.
Inside Bets: Odds on Roulette
The following table shows the payouts and odds for inside bets in both European and American roulette:
| Bet | Payout | European Roulette Odds | American Roulette Odds |
| Straight | 35:1 | 2.7% | 2.6% |
| Split | 17:1 | 5.4% | 5.3% |
| Street | 11:1 | 8.1% | 7.9% |
| Corner | 8:1 | 10.8% | 10.5% |

| Top Line (American) | 6:1 | NA | 13.2% |
What are Call Bets and their Odds on Roulette?
A call bet in the game of roulette can have different meanings depending on the context. It also refers to credit bets made by well-known players who don't have enough chips to continue betting. The casino allows them to make the bet through the croupier temporarily.
However, the term "call bets" is more commonly associated with French roulette, which is a variation of European roulette with additional rules and bets. In this context, call bets are specific bets placed on specific roulette numbers on the wheel. There are five call bets, divided into fixed call bets and variable call bets:
Fixed call bets
Voisins du zero (neighbours of zero) - This bet includes zero and the 16 numbers surrounding it on the roulette wheel. The player must place a total bet of nine units, including specific bets on a basket bet (0-2-3), a corner bet (25-26-28-29), and five split bets (4-7, 12-15, 18-21, 19-22, and 32-35). The odds of achieving a win is 45.9%.
Jeu zero (zero game) - Similar to the voisins du zero roulette bet, focusing on zero and the six numbers that are closest to it. The player must place a total bet of four units, including a straight bet on 26 and three split bets (0-3, 12-15, and 32-35). The odds of achieving a win is 18.9%.
Tiers du cylindre (thirds of the wheel) - This wager covers 12 numbers located on the opposite side of voisins du zero. It entails a bet of six units on six split bets (5-8, 10-11, 13-16, 23-24, 27-30, and 33-36). The odds of achieving a win are 32.4%.
Orphelins (orphans) - Orphelins are the eight numbers not included in the above bets. To place this bet, five units are wagered on a straight bet on 1 and four split bets (6-9, 14-17, 17-20, and 31-34). The odds of achieving a win are 21.6%.
Variable call bets
Neighbours - This bet is a straight bet on a single number, together with four extra straight bets on two numbers on either side. For example, if you bet on number 6, the neighbours bet will also include numbers 17 and 34 on the left side and 27 and 13 on the right side. The chance of winning this bet is 13.5%.
Final - A final bet involves a group of numbers that share the same final digit. For instance, it could include 0-10-20-30, 6-16-26-36, or 9-19-29. The odds of winning Roulette depend on whether you're placing a wager on 3 or 4 numbers, with probabilities of 10.8% or 8.1% respectively.
How to Improve the Best Roulette Odds
Since the game of Roulette is a game of chances, there are some tips and tricks which you can apply to improve the odds of winning Roulette.
Opt for European Roulette
When given the choice between European and American roulette, always choose European. The absence of the double-zero slot in European roulette reduces the house edge to 2.7%, offering better odds compared to the 5.26% house edge in American roulette.
Understand the Roulette Table Odds
Take the time to familiarize yourself with the odds of winning roulette bets and how they correspond to potential payouts. This will enable you to make informed decisions while playing.
Opt for Outside Bets
While outside bets may have lower payout odds, they have a higher probability of winning. In European roulette, the chance of hitting an outside bet ranges from 32.4% to 48.6%. On the other hand, inside bets have a lower probability, ranging from 2.7% (straight) to 16.2% (six line).

Best Roulette Odds FAQ
To calculate the odds of winning roulette and a specific bet, you need to consider the number of possible winning outcomes compared to the total number of possible outcomes. For example, in European roulette, the odds of winning a bet on a single number are 1 in 37 since there are 37 numbers on the wheel.
While there are various betting strategies that players use in roulette, it's worth keeping in mind that roulette is a game of chance, and the outcome is determined by a random number generator or the physical properties of the roulette wheel.
The odds on Roulette vary depending on the type of bet you place and the roulette game variant you are picking. Refer to the tables in this guide to check out the odds based on inside and outside bets as well as the roulette variant.
The main difference between European and American roulette odds lies in the presence of the double zero (00) on the American wheel. The additional double zero increases the total number of slots on the wheel, resulting in higher odds for the casino and a higher house edge compared to European roulette.
Inside bets in roulette are wagers placed on specific numbers or groups of numbers within the grid on the betting table. These bets have higher payouts but lower odds of winning. Outside bets, alternatively, are placed on larger groups of numbers, such as red or black, odd or even, or high or low numbers. Outside bets have lower payouts but higher odds of winning.
