| Updated: September 26, 2025Roulette offers many betting opportunities, allowing players to place more than twenty different types of wagers. Most of these wagers carry the same house edge, with only a few exceptions.
The two main bet categories are inside and outside bets, both accepted at all single-zero and double-zero tables. Call bets form a separate category and are available only at tables with French or European wheels. Additionally, some casinos offer unique wagers that are exclusive to their roulette tables.
The following article provides detailed information about the two main groups of roulette bets – inside and outside – including their true odds, casino payouts, probabilities, and chip positions on the layout. We also explain which bets players should avoid and which offer the most favorable odds.
Outside Bets in Detail
Let’s start with outside bets, as they are the simplest to understand and place. These wagers are placed on the perimeter of the layout, outside the main grid that contains 37 or 38 numbers. Outside bets offer better chances of winning, but they yield smaller payouts – either even money or 2 to 1. With these bets, players wager on the numbers’ characteristics rather than on individual numbers. Each of these wagers is described below.
| Outside Bet | Casino Payout | True Odds in Single-Zero Games | True Odds in Double-Zero Games | Probability of Winning in Single-Zero Games | Probability of Winning in Double-Zero Games |
|---|---|---|---|---|---|
| Red/Black (Rouge et Noir) | 1 to 1 | 11⁄18 to 1 | 11/9 to 1 | 48.65% | 47.37% |
| Even/Odd (Impair et Pair) | 1 to 1 | 11⁄18 to 1 | 11/9 to 1 | 48.65% | 47.37% |
| High/Low (Passe et Manque) | 1 to 1 | 11⁄18 to 1 | 11/9 to 1 | 48.65% | 47.37% |
| Dozens (Douzaine) | 2 to 1 | 21⁄12 to 1 | 21/6 to 1 | 32.43% | 31.58% |
| Columns (Colonne) | 2 to 1 | 21⁄12 to 1 | 21/6 to 1 | 32.43% | 31.58% |
Red/black bets
Even/odd bets High/low bets Dozen bets Column betsRed/black bets
With red/black bets, the player tries to guess the color of the winning number. This bet is placed in the center of the outside betting area, where you can see one red and one black diamond-shaped box. These may contain the words “red” or “black,” depending on the casino.
You have almost even odds of winning or losing, since there are 18 red and 18 black numbers on the roulette wheel, plus the green zero, which gives the house its edge. Bets on color lose when the zero hits, which slightly tips the odds in favor of the house.
The probability of winning with a bet on black, for example, is 48.65% because there are 18 winning pockets on the wheel and 19 losing ones. The payout for winning color bets is even money, or 1 to 1.
Even/odd bets
Even/odd bets are even-money bets based on the winning number’s parity. The chips for these bets are placed in the boxes on either side of the red and black diamonds. They are easy to spot thanks to the “Even” and “Odd” markings.
The wheel contains 18 odd and 18 even numbers. In mathematics, the number 0 is considered even, but this is not the case in the game of roulette. Here, 0 and 00 are neither odd nor even, which means even/odd bets lose when either zero appears. The house pays you 1 extra chip for every chip you wager, or 1 to 1.
High/low bets
High/low bets are placed on either the 18 low numbers (1 through 18) or the 18 high numbers (19 through 36). You place your chips in the boxes marked 1-18 or 19-36, depending on which half you want to back. Zero is included in neither group, so these bets automatically lose when 0 or 00 appears. Winning high/low bets pay 1 to 1, or even money.
Dozen bets
Dozen bets comprise three groups of 12 numbers each. These are designated as 1st 12 (1 to 12), 2nd 12 (13 to 24), and 3rd 12 (25 to 36) on the outside section of the layout. You win if any of the 12 numbers from your selected dozen hits. Dozen bets also lose to 0 and 00 since the zeros are not included in any of the three dozens. The probability of winning with a dozen bet on a single-zero wheel is 32.43% and the payout casinos offer is 2 to 1.
Column bets
Column bets also feature three groups, each consisting of 12 numbers from one of the three columns on the layout. You place your chips in the betting boxes labeled “2 to 1.” The numbers in the columns are not arranged in numerical order on the layout, unlike those in dozen bets.
Thus, the first column includes numbers 1, 4, 7, 10, 13, 16, 19, 22, 25, 28, 31, and 34. The second column comprises numbers 2, 5, 8, 11, 14, 17, 20, 23, 26, 29, 32, and 35, and the third column features numbers 3, 6, 9, 12, 15, 18, 21, 24, 27, 30, 33, and 36.
As you can see, zero is not part of any of the three columns. These bets also lose when the ball lands in the green pocket. The payout for column bets is the same as that for dozen bets – 2 to 1.

Inside Bets in Detail
Inside bets are the second major category of wagers you can make in roulette. They cover either single numbers or groups of 2 to 6 numbers. This category derives its name from the fact that players place their chips on the inside section of the table layout, where the numbers 0 through 36 are listed. Inside bets are riskier because they cover fewer numbers, but they compensate with juicier payouts.
| Inside Bet | Casino Payout | True Odds in Single-Zero Games | True Odds in Double-Zero Games | Probability of Winning in Single-Zero Games | Probability of Winning in Double-Zero Games |
|---|---|---|---|---|---|
| Straight-up bet | 35 to 1 | 36 to 1 | 37 to 1 | 2.70% | 2.63% |
| Split bet | 17 to 1 | 171/2 to 1 | 18 to 1 | 5.40% | 5.26% |
| Street bet | 11 to 1 | 111⁄3 to 1 | 112/3 to 1 | 8.11% | 7.89% |
| Corner bet | 8 to 1 | 81/4 to 1 | 81/2 to 1 | 10.81% | 10.53% |
| Double street bet | 5 to 1 | 51/6 to 1 | 51/3 to 1 | 16.22% | 15.79% |
| Basket bet | 8 to 1 | 81/4 to 1 | 81/2 to 1 | 10.81% | N/A |
| Five-number bet | 6 to 1 | 61/5 to 1 | 63/5 to 1 | N/A | 13.16% |
| Snake bet | 35 to 1 | 36 to 1 | 37 to 1 | 32.43% | 31.58% |
Seasoned dealers in larger land-based casinos rarely make mistakes when paying out winning wagers. Still, we suggest you memorize the payouts of all available roulette bets just to protect yourself against any potential dealer errors.
Of course, you will experience no such issues if you play the game online. Unlike humans, accredited casino software is immune to errors and automatically pays at the correct ratio based on the type of bet you win.
Unlike other casino games of chance, such as craps, all roulette bets put you at the same disadvantage against the house. This edge stands at 2.70% in variations that play on single-zero wheels unless the La Partage or En Prison rules are in place.
The extra 00 pocket on American tables almost doubles this percentage to 5.26%. The only exception is the five-number bet, which pays at poorer casino odds and puts you at a dismal disadvantage of 7.90%. Don’t be a sucker – refrain from placing this bet!
Straight up bet Split Bet Street bet Corner bet Double street bet Basket bet Five number bet Snake betStraight up bet
Straight-up bets are placed on a single number. To place such a bet, put your chips in the betting box that contains your chosen number. The chips should not touch any of the borders of the box. You receive a payout of 35 to 1 if the ball lands on the number you selected. In a single-zero game, the probability of hitting one specific number is 1 in 37, or about 2.70%.
Split Bet
The split is a combination bet that covers two adjacent numbers on the table layout – for example, 3/6, 9/12, or 22/23. You place your chips on the line that separates the two selected numbers. A payout of 17 to 1 is awarded if either number hits.
Street bet
The street bet is a combination wager that covers a row of three consecutive numbers on the layout. You place the bet by putting your chip or stack of chips on the border of the first number in your chosen row. For example, if you are betting on the street with the numbers 4, 5, and 6, place your chips on the line that separates the 4 from the box marked 1st 12. You win 11 chips for every chip you wager if the ball lands on any of the three selected numbers.
Corner bet
A corner bet is a combination of four consecutive numbers that share a common corner on the layout, such as 16/17/19/20 or 23/24/26/27. Some players refer to it as the square or four-number bet. It pays at casino odds of 8 to 1 when the ball lands on any of the four selected numbers. To make this bet, place your chips at the intersection of the vertical and horizontal lines in the center of the four boxes.
Double street bet
The double street bet, also known as a line bet or six-line bet, comprises six sequential numbers positioned in two adjacent rows, such as 1 through 6 and 7 through 12. The chips for this bet are placed on the intersection between the two streets. If one of the six selected numbers wins, the player is paid at odds of 5 to 1.
It is important to remember that, while the six numbers are arranged sequentially on the table layout, they are not positioned sequentially on the wheel. You can read more about the wheel’s number sequence in our next article.
Basket bet
The basket bet covers four specific numbers: 0, 1, 2, and 3. This bet can only be placed at single-zero tables and offers a payout of 8 to 1 when any of the four numbers hits. Place your chips on the intersection that separates the 0, the 1, and the box for the first dozen. This wager carries the same house edge as every other bet on a single-zero table, which is 2.70%.
Five number bet
The five-number bet is similar to the basket bet, but this one can only be made on the American layout with the double zero because it covers the numbers 0, 00, 1, 2, and 3. This bet is considered a sucker bet in roulette. It offers terrible odds of 6 to 1. These poor payouts raise the house edge to 7.90%. Chips are placed on the intersection that separates the single zero and 1.
Snake bet
The snake bet is a combination wager that comprises 12 red numbers. Each number is covered by an individual chip, meaning you are betting straight up on all 12 selections. It is recommended to use the same betting unit for each bet.
The numbers in question are 1, 5, 9, 12, 14, 16, 19, 23, 27, 30, 32, and 34. When you place your chips on the layout, you will quickly notice they form a zigzagging pattern that resembles a slithering snake. This is where the bet gets its name. You win at odds of 35 to 1 if one of the numbers hits, but you lose the chips you placed on the other 11 numbers. The higher payout is more than enough to offset these losses.
Call Bets in Brief
This category comprises a variety of special bets that include specific combinations of numbers the way they are positioned on the different sections of the roulette wheel. These wagers are posted on an oval section on the layout that resembles a racetrack.
Call bets are accepted at single-zero roulette tables that follow the European or French rules. The double-zero wheels utilized at the American roulette tables use a different number sequence, making it impossible to place call bets on the same wheel sections.
You are probably wondering where the name of this category of wagers is derived from. Well, these are more complex and require multiple chips. Players at landbased casinos would verbally call the name of the bet they want to make but without immediately posting chips on the layout to cover the cost of the wager.
In some jurisdictions like the UK, this is seen as betting on credit and is strictly prohibited. The dealer would accept a call bet but only on condition the player has enough chips on the rail to pay in case they lose. Below, we feature brief explanations about the three most popular types of call bets. You can find more exhaustive information in our article on how to diversify your roulette game with call bets.
Tiers du Cylindre Voisins du Zero OrphelinsTiers du Cylindre
Tiers du Cylindre translates as “one third of the wheel” from French. Respectively, this wager covers a total of 12 numbers on the wheel, namely 27, 13, 36, 11, 30, 8, 23, 10, 5, 24, 16, and 33. The 12 numbers are covered with 6 split bets and pay 17 to 1.
Voisins du Zero
Voisins du Zero means “neighbors of zero” in French. This type of special bet includes a total of 17 numbers in adjacent pockets on the wheel – 22, 18, 29, 7, 28, 12, 35, 3, 26, 0, 32, 15, 19, 4, 21, 2, and 25. Players need at least 9 chips to make this complex wager. You post a chip on the 4/7, 12/15, 18/21, 19/22, and 32/35 splits, 2 chips on the trio comprising 0, 2, and 3, and two chips on the corner of 25/26/28/29. The payout depends on the type of bet you win with.
Orphelins
Orphelins is the French word for “orphans”, which perfectly describes this type of call bet. It comprises the “orphaned” numbers that fall neither in the Tiers nor in the Voisins sections. The orphans sit in the two sliced wheel segments between numbers 22 and 33 and numbers 25 and 27.
The group includes a total of 8 numbers, namely 9, 31, 14, 20, 1, 17, 34, and 6. Players can cover this bet with a minimum of 5 chips. One of these is posted straight up on number 1 and the other four chips are placed on each of the following splits – 6/9, 14/17, 17/20, and 31/34.
The Best and the Worst Bets in Roulette
So what is the best bet one can make at the roulette table?
You are fighting the same house edge regardless of what you bet on at single-zero tables but stand better chances of registering a win with any of the five types of outside bets.
These give you a better shot at winning because you cover larger sections of the wheel with them. For instance, if you bet on black or even, 18 numbers result in a win while the other 19 lead to a loss. Needless to say, the higher probability and frequency of winning are compensated for with smaller payouts.
As for the worst possible bet in roulette, the answer should be quite obvious at this point, or at least, if you have read the article carefully. This title goes to the notorious five number bet, which consistently tops the charts of the worst bets you can make in a casino in general.
This bet is not worth the bother due to its huge house edge (7.90%). What's more, it is available only in American roulette where you are fighting a high house edge, to begin with. You better stay away from the five number bet and the double-zero wheels altogether.
