Despite being around for centuries, roulette remains relevant in gambling establishments to this day. The game continues to thrive partly because both land-based and online casino operators constantly reinvent it by introducing new and ingenious roulette variants.
One original version that immediately comes to mind is Mouse Roulette. It was available for a brief period at Reno’s Harold’s Club in the early 1940s. The game featured a large box with 50 numbered holes.
Once patrons had placed their bets, the table staff would release a wood mouse from a nearby cage and place it on top of the numbered box. The winning number was determined as soon as the tiny rodent scooted into one of the box’s holes.
It didn’t take long for players to realize that the game was flawed and easy to exploit. The creature would become startled and dart into the nearest hole whenever someone made a loud noise. Additionally, the rodent would repeatedly dive into the same numbered holes because it could smell the mice that had been used previously. Harold’s Club removed the game from its floors after about a week because it was blatantly unprofitable for the house.
Mouse Roulette has been gone as a casino game for more than 70 years now, but there are countless other variations that give this old game a new spin. In the following article, we discuss some of the most original ones. Read on, and you may find your next favorite roulette variation.
Unique Spins on a Century-Old Game
Standard versions such as European and American roulette are fun to play, but they can become repetitive after a while. You are probably familiar with the differences between these two variants. If not, head back to our roulette guide and read the article on American and European Wheel Sequences.
To keep players engaged, many land-based casino operators build on the fundamentals of the classic game and introduce inventive rules to give it a fresh spin. Such is the case with the six unconventional land-based roulette variants we discuss below.
Prime Time Roulette
Back 2 Back Roulette
Riverboat Roulette
Double Action Roulette
Roulette-18Alphabetic Roulette
Alphabetic Roulette in Brief
Minimum payout: 1 to 1
Maximum payout: 23 to 1
House edge: 4%
Number of pockets: 25
Where to find it: The D Las Vegas (formerly Fitzgeralds Hotel and Casino).
This bespoke variation debuted in 2007 at Las Vegas’ Fitzgeralds Hotel and Casino (now rebranded as The D Las Vegas). Alphabetic Roulette removes the familiar numbers from the wheel and replaces them with letters.
There are 24 pockets for the letters A through X, plus one pocket that contains the last two letters of the English alphabet, Y and Z. Unlike conventional roulette, Alphabetic Roulette uses not three but six colors: pink, orange, green, blue, red, and yellow. Each of the six colors corresponds to four letters.
In this variation, players may wager on individual letters or on groups of two, three, or four letters. If the game has not yet piqued your interest, it likely will when you discover you can bet on letters that combine to form specific words and phrases, such as Party Pit (P, A, R, T, Y, and I) and Roulette (R, O, U, L, E, and T).
The game also supports dozen and column bets. The dozen bet in Party Roulette is placed on one of two groups of 12 letters each (A through L and M through X). Column bets likewise cover 12 letters in the order they appear on the layout. Alphabetic Roulette has a house edge of 4%, which is still lower than that of double-zero games. See how it pays in the table below:
| Type of Wager in Alphabetical Roulette | Casino Payouts |
|---|---|
| Straight Up bet on individual letters | 23 to 1 |
| Split bet on 2 adjacent letters | 11 to 1 |
| Top Line bet on A, B, Y, and Z | 7 to 1 |
| Four Way bet on 4 adjacent letters | 5 to 1 |
| Color bet on one of the 6 colors | 5 to 1 |
| Six Way bet on 6 letters (A to F, G to L, M to R or S to X) | 3 to 1 |
| Party Pit bet | 3 to 1 |
| Roulette bet | 3 to 1 |
| Dozen bet | 1 to 1 |
| Column bet | 1 to 1 |
Prime Time Roulette
Prime Time Roulette in Brief
Minimum payout: 1 to 1
Maximum payout: 299 to 1 or 100 to 1 (depends on casino policies)
House edge: 5.26%
Number of pockets: Mostly 38
Where to find it: Some Nevada casinos
Prime Time Roulette is offered by casinos in Nevada, so it follows the American rules and uses a wheel with both single and double zeros. One interesting aspect of this variation is that it offers an optional side wager on prime numbers, i.e., whole numbers that are divisible only by themselves and 1.
There are 11 prime numbers on the roulette wheel – 2, 3, 5, 7, 11, 13, 17, 19, 23, 29, and 31. The side bet loses when the ball settles on a non-prime number. When a prime number hits, the dealer places a marker that reads “1” on top of the Prime Time bets, indicating the number has been spun once.
The count increments again if a prime number occurs on the next spin. The process continues for up to five or seven consecutive spins (depending on the casino’s policy) that produce prime numbers. Only then does the dealer settle the winning Prime Time side bets.
When a non-prime number appears between prime spins, it breaks the cycle and the Prime Time marker is removed. Bets are paid according to the number of successive prime spins achieved before the non-prime number. Keep in mind that you can place this wager only at the beginning of a new Prime Time session – either after a non-prime number has hit or after prime numbers have been spun consecutively to the maximum of five or seven times.
Below are the three payout schedules for prime numbers that appear on consecutive spins, as listed by the Nevada Gaming Control Board:
| Number of Primes Occurring in Succession | Payout 1 | Payout 2 | Payout 3 |
|---|---|---|---|
| 1 prime | 1 to 1 | 1 to 1 | 1 to 1 |
| 2 primes in a row | 3 to 1 | 3 to 1 | 3 to 1 |
| 3 primes in a row | 6 to 1 | 7 to 1 | 6 to 1 |
| 4 primes in a row | 10 to 1 | 12 to 1 | 10 to 1 |
| 5 primes in a row | 20 to 1 | 25 to 1 | 50 to 1 |
| 6 primes in a row | 50 to 1 | 50 to 1 | N/A |
| 7 primes in a row | 299 to 1 | 100 to 1 | N/A |
Back 2 Back Roulette
Back 2 Back Roulette in Brief
Minimum payout: 1 to 1
Maximum payout: 1,000 to 1 for the Back 2 Back side wager
House edge: 5.26%
Number of pockets: 38
Where to find it: Atlantis Casino Resort in Reno and several other Nevada casinos
Back 2 Back Roulette offers an exciting twist to this old favorite with a side bet that gives players the chance to claim substantial payouts. The game is available in Reno and has been approved by the Nevada Gaming Control Board.
The Back 2 Back side bet is optional and pays whenever the previous winning number repeats on the next spin of the wheel. In essence, you need the same number to appear twice in a row to win.
A random prize of 10x, 50x, or 1,000x your side-bet stake is then awarded. Other than that, Back 2 Back Roulette follows the standard rules: it uses a double-zero wheel and supports the conventional inside and outside bets, which return their usual payouts.
Riverboat Roulette
Riverboat Roulette in Brief
Minimum payout: 1 to 1
Maximum payout: 7 to 2 for color bets and 35 to 1 for straight up bets
House edge: 5.26% overall, 5.26% for yellow, white, and teal, 4.21% for purple and pink, and 2.63% for orange and blue
Number of pockets: 38
Where to find it: The Golden Gate Casino in downtown Las Vegas
Riverboat Roulette is offered at the Golden Gate Casino. This variation features a 38-pocket wheel and allows for all the standard inside and outside betting options. Conventional bets pay at their usual casino odds.
The layout contains alternating red and black numbers (1 through 36) and two green zeros. The twist lies in the fact that each of the 38 numbers is assigned an additional color. The wheel’s inner pockets, where the ball eventually settles, are painted in these extra colors. The table below shows all the numbers associated with each color.
| Color | Numbers of That Color | Payout |
|---|---|---|
| Red | 25, 36 | Push |
| Black | 26, 35 | Push |
| Green | 0, 00 | Push |
| Teal | 5, 17, 32 | 2 to 1 ($2 per dollar bet) |
| Yellow | 31, 18, 6 | 2 to 1 ($2 per dollar bet) |
| Pink | 19, 8, 12, 29 | 8 to 5 ($1.6 per dollar bet) |
| Purple | 20, 7, 11, 30 | 8 to 5 ($1.6 per dollar bet) |
| White | 10, 27, 1, 13, 14, 2, 28, 9 | 7 to 2 ($3.5 per dollar bet) |
| Orange | 23, 4, 16, 33, 21 | 7 to 5 ($1.4 per dollar bet) |
| Blue | 24, 3, 15, 34, 22 | 7 to 5 ($1.4 per dollar bet) |
So, essentially, you are presented with seven additional betting options on the extra colors. The payouts for these bets are proportionate to the number of pockets of the respective color. Therefore, a wager on blue (five pockets) has a higher probability of winning than one on teal or yellow (three pockets each).
The game bears some resemblance to craps because bets placed on the extra colors are sometimes resolved after multiple spins. The player does not immediately lose if the ball lands on a color other than the one selected, unless it settles in one of the white pockets.
For example, assume you wager $10 on orange but pink hits instead. Your bet remains on the table. This situation is known as a push and also occurs when the ball lands in a green (0, 00), black (26, 35), or red pocket (25, 36). However, if the ball lands on white, your color wager loses immediately – unless, of course, you had bet on white.
When a push occurs, you have three options: leave your chips on the layout for the next spin, take the bet down, or increase the wager by adding more chips. If you choose to let the push bet ride, the wheel is re-spun until your chosen color or white hits. Because color wagers are considered outside bets, they can be placed at the table minimum. The Golden Gate Casino accepts bets from $5 to $2,500 per spin.
The overall house edge of the game is 5.26%, identical to that at all double-zero tables. The casino’s advantage for the color bets varies as follows: 5.26% for white, 4.21% for purple and pink, 2.63% for orange and blue, and 5.26% for teal and yellow.
Double Action Roulette
Double Action Roulette in Brief
Minimum payout: 1 to 1 for one wheel ring and 3 to 1 for two wheel rings
Maximum payout: 35 to 1 for one wheel ring and 1,200 for two wheel rings
House edge: 5.33% for outside bets, 12.27% for double straight up bets, and 6.94% for 7-number bets (the figures are accurate for double ring-wheel bets made on single-zero games)
Number of pockets: The game is available in both 0 and 00 formats
Where to find it: The M Casino in Las Vegas, among others
With this roulette variation, players enjoy twice the action because the game plays on a wheel that has two rings with numbers instead of only one. The rings rotate in opposite directions and produce two outcomes on each spin. Players can wager on the outer ring, the inner ring, or both. The game is also available in a single-zero format.
The table uses a modified layout that contains 6×6 sections instead of the usual 3 sections with 12 numbers each. When players bet only on the inner or outer rings, they are paid at the standard odds for all wagers except the 8-number and 7-number bets.
The 8-number bet is offered in double-zero games and covers 0, 00, 1, 2, 3, 4, 5, and 6. The 7-number bet is available at single-zero tables and includes 0, 1, 2, 3, 4, 5, and 6. Things become trickier when a player parlays a wager by betting on both the outer and inner rings.
To collect a payout, the wager must be successful on both rings. Here are the payouts along with the probabilities of winning on both rings. These are accurate for Double Action Roulette with a single zero.
| Type of Double Action Bet | Payouts for Winning on Both Wheel Rings | Probability of Winning on Both Wheel Rings |
|---|---|---|
| Two red or two black numbers | 3 to 1 | 23.66% |
| Two even or two odd numbers | 3 to 1 | 23.66% |
| Two high or two low numbers | 3 to 1 | 23.66% |
| Two numbers of the same dozen | 8 to 1 | 10.52% |
| Two numbers of the same column | 8 to 1 | 10.52% |
| Two numbers from the 7-number bet | 25 to 1 | 3.58% |
| Two matching single numbers | 1,200 to 1 | 0.07% |
The house edge in Double Action Roulette depends on whether you are playing on a double-zero or single-zero wheel, and it also varies by wager type. On a single-zero wheel, straight-up bets that hit on both rings yield a house edge of 12.27%. The outside wagers and the 7-number bet give the house an advantage of 6.94% and 5.33%, respectively.
Roulette-18
Roulette-18 in Brief
Minimum payout: 1 to 1
Maximum payout: 17 to 1
House edge: 2.63% for even-money bets and 5.26% for all other wagers
Number of pockets: 20
Where to find it: Grosvenor casinos in the United Kingdom
Most people associate roulette with a spinning wheel and a tiny white ball. Well, guess what? There is no ball or wheel in Roulette-18. That’s right. In this unique variation, the outcome is determined by the toss of a 20-sided die containing numbers 1 through 18 plus 0 and 00.
If the die shows 00, it is rolled again and wagers neither win nor lose. The game supports standard roulette wagers such as straight up, split, street, corner, double street, odd/even, red/black, and low/high bets. Instead of losing their entire stakes when the die shows zero, Roulette-18 players recover half of their original wagers on even-money propositions.
However, there is a reduction in payouts for some bets to compensate for the smaller range of possible outcomes, so the probabilities differ from those in standard roulette.
| Type of Roulette-18 Bet | Casino Payout | Probability of Winning |
|---|---|---|
| Straight up bet on single numbers 0 through 19 | 17 to 1 | 5.26% |
| Split bet on 2 numbers | 8 to 1 | 10.53% |
| Street bet on 6 numbers | 5 to 1 | 15.79% |
| Corner bet on 4 numbers | 7 to 1 | 21.05% |
| Double street bet on 6 numbers | 2 to 1 | 31.58% |
| Red/black (9 numbers for each color) | 1 to 1 | 47.37% |
| Odd/even (9 numbers for each parity) | 1 to 1 | 47.37% |
| Low (1-9) and High (10-18) | 1 to 1 | 47.37% |
Roulette-18 is available at select Grosvenor casinos in the United Kingdom. The house edge for even-money bets on color, range, and parity is lower than that in single-zero roulette, at just 2.63%. The casino holds an advantage of 5.26% for all of the other available bets.
Spicing Up the Action with Unique Online Variations
Some roulette fans do not live in proximity to any landbased casinos and lack the resources to cover the traveling expenses needed for a gambling trip. Luckily for them, the game has made a smooth transition from landbased to online casinos. The latter give players a vast choice of roulette variations they can conveniently enjoy on desktop and mobile.
The tried and true variants like French, European, and American roulette are readily available at most online casinos. Dozens of original variants have emerged in recent years as casino software providers strive to capture a whole new audience of roulette players. Here are 6 bespoke online roulette variations you can play from the comfort of your surroundings.
Double Ball Roulette
No Zero Roulette
Diamond Bet Roulette
Spread-Bet Roulette
Spingo
Pinball RouletteDouble Ball Roulette
Double Ball Roulette in Brief
Minimum payout: 1 to 1
Maximum payout: 1,200 to 1
House edge: 2.70%
Number of pockets: 37 in Felt’s online version (38 in Tropicana’s landbased version)
Where to find it: Double Ball Roulette can be played online at casinos using the Felt Gaming platform
Double Ball Roulette was first introduced at Las Vegas’ Tropicana Casino in 2014, where it was played on a double-zero wheel. Later, software supplier Felt Gaming adapted the game for online play. This unique take on roulette offers twice the excitement because it uses two balls instead of one.
Felt’s version employs a single-zero wheel and largely follows European rules. The presence of two balls opens up additional betting opportunities. Players can launch the second ball themselves after the first one is released.
The game has three main peculiarities. First, inside bets win if either ball lands in the designated pocket, although the payouts are reduced. If the second ball also hits, the player collects double the listed payout. Here are the payouts for inside bets that win with one ball only:
| Type of Double Ball Roulette Inside Bet | Payouts for a Single Ball Hitting |
|---|---|
| Straight up bet | 17 to 1 |
| Split bet | 8 to 1 |
| Street bet | 5 to 1 |
| Corner bet | 3 to 1 |
| Double street bet | 2 to 1 |
Second, outside bets succeed only when both balls settle into winning pockets. For example, an outside bet on even wins when both balls land on even numbers. Finally, there is the Double Ball Jackpot, awarded on a spin in which both balls settle on your chosen number. Chips for the jackpot bet are placed on a special racetrack layout. See the paytable for the outside bets in Double Ball Roulette below.
| Types of Double Ball Roulette Outside Bet | Payouts when Both Balls Hit |
|---|---|
| Black and red | 1 to 1 |
| Black or red | 3 to 1 |
| Odd or even | 3 to 1 |
| High or low | 3 to 1 |
| Two numbers of the same column | 8 to 1 |
| Two numbers of the same dozen | 8 to 1 |
| Any same number | 35 to 1 |
| Double Ball Jackpot | 1,200 to 1 |
No Zero Roulette
No Zero Roulette in Brief
Minimum payout: 1 to 1
Maximum payout: 35 to 1
House edge: No house edge is built into the game itself but the casino taxes players on their winnings
Number of pockets: 36
Where to find it: No Zero Roulette is available at BetVoyager Casino
We have heard of instances in which casinos temporarily removed the zero pocket to boost attendance. That idea likely inspired No Zero Roulette. This game is available at BetVoyager Casino and is one of the operator’s most popular offerings.
This version of roulette has no inherent house edge because the green zero is completely removed from the wheel, which now contains only 36 pockets – 18 black and 18 red. Standard payouts are awarded for winning bets, meaning the game effectively pays at true odds.
You might wonder how the casino profits from such a game. The answer is simple: the casino deducts 10% of your winnings at the end of your betting session as a fee. To their credit, this policy is clearly displayed when the game loads.
No Zero Roulette is worth considering because the game itself lacks a built-in house edge. However, the 10% fee on profits functions much like a house edge, ensuring the casino inevitably comes out ahead in the long run.
Diamond Bet Roulette
Diamond Bet Roulette in Brief
Minimum payout: 1 to 1
Maximum payout: 100x the bet (Diamond Bet Jackpot)
House edge: 4.61% – 7.89%
Number of pockets: 38
Where to find it: Diamond Bet Roulette is offered by many Playtech-powered casinos
Developers at renowned software studio Playtech have taken the classic casino game and added a bit of sparkle with an extra wager. Diamond Bet Roulette is played on a wheel with 38 pockets containing numbers 0 through 36 plus one special pocket reserved for the Diamond bet.
Aside from that, the game supports the conventional inside and outside wagers along with a variety of call bets such as Orphelins, Tiers, Voisins, and Neighbors. The outer rim of the wheel in Diamond Bet Roulette features the following multipliers: 15x, 20x, 25x, 30x, 35x, 40x, 45x, 50x, 60x, and 100x.
These multipliers are selected at random during winning spins and apply only to the Diamond bet; winnings from regular bets are not multiplied. The house edge ranges between 4.61% and 7.89%, which slightly detracts from the game’s appeal.
Spread-Bet Roulette
Spread-Bet Roulette in Brief
Minimum payout: 1 to 1
Maximum payout: 35 to 1 for straight up bets and 400 to 1 for the 0-1 spread bet
House edge: 2.70%
Number of pockets: 37
Where to find it: At Playtech-powered online casinos
Spread-Bet Roulette is another bespoke take on the classic game that comes from Playtech. The variant follows European rules but broadens the betting options by introducing a golden inner ring with numbers 0 through 36.
In addition to the conventional inside and outside wagers, the game enables players to experiment with spread bets. The golden inner ring serves a two-fold purpose. First, it doubles the payout on zero. Second, it provides the foundation for the spread bet.
Additional colored grids on the layout are reserved for these side wagers. When the ball settles in a pocket, the sum of the numbers on the inner and outer rings determines whether the optional spread bet wins.
For example, suppose the ball lands on 17 on the outer ring. Directly beneath it is the number 2 on the inner ring, setting the spread at 19. You win at odds of 2 to 1 if you have placed a side bet on the 19-33 spread range. See how the other spreads pay below.
| Spread-Bet Range | Casino Payout |
|---|---|
| 0-1 spread | 400 to 1 |
| 2-11 spread | 15 to 1 |
| 12-18 spread | 10 to 1 |
| 19-33 spread | 2 to 1 |
| 34-54 spread | 1 to 1 (even money) |
| 55-67 spread | 7 to 1 |
| 68-72 spread | 80 to 1 |
Spingo
Spingo in Brief
Minimum payout: 1 to 1
Maximum payout: 31 to 1
House edge: 4.76%
Number of pockets: 25 (and 21 numbered balls)
Where to find it: at Microgaming online casinos
Spingo is a hybrid of bingo and roulette, created by supplier Microgaming. The game is played on a wheel with 25 pockets: 8 red, 8 yellow, 8 blue, and 1 green. At the center of the wheel is a ball machine that releases one of 21 numbered balls at a time – 20 balls numbered 1 through 10 and one ball with 0.
Players may bet on any of the four colors, on individual numbers, on odd/even, on low (1–5), on high (6–10), or on combinations of colors and numbers. The overall house edge of Spingo is 4.76% and is based on the following payouts:
| Type of Spingo Bet | Casino Payout | Probability of Winning |
|---|---|---|
| Color (red, blue or yellow) | 2 to 1 | 32.00% |
| Green only | 23 to 1 | 4.00% |
| Zero | 19 to 1 | 4.76% |
| A single number (1 to 10) | 9 to 1 | 9.52% |
| 1-5 or 6-10 | 1 to 1 | 47.61% |
| Odd/even | 1 to 1 | 47.61% |
| Combination of numbers and colors | 31 to 1 | 3.05% |
Pinball Roulette
Pinball Roulette in Brief
Minimum payout: 1 to 1
Maximum payout: 35 to 1
House edge: 2.70%
Number of pockets: 37
Where to find it: at Playtech-powered casinos
Players will immediately notice that Pinball Roulette by Playtech is no ordinary game. The variant lacks almost all of the traditional elements of roulette: there is no wheel or racetrack, yet the game still adheres to conventional European rules.
Most of the screen is occupied by the betting layout, which contains the single zero plus grids with numbers 1 to 36. Below it is a section resembling a piano keyboard, with alternating red and black numbers. This is where you place your Neighbor bets.
In Pinball Roulette you can place the same wagers as in regular roulette. The difference lies in how the outcome is determined. When you click the Bet button, the layout slides vertically to the side and reveals a pinball field.
A small ball is then shot out of a funnel and bounces through the pins and flippers of the machine before falling into one of the pockets of the sliding keyboard-like section. If you win, you can gamble your profits for a chance to multiply them by up to 10x. Pinball Roulette has a house edge of 2.70% and pays at standard roulette odds.

Closing Thoughts on Landbased vs. Online Roulette Variations
As you can see, both online and landbased casinos offer a broad assortment of roulette variations that deviate from the standard set of rules. Both formats have their advantages and disadvantages.

Online casinos give you instant access to a range of intriguing roulette variants, available at your fingertips. You can play them in demo format if you wish or go for real-money payouts by depositing into your online casino account.

Playing roulette at landbased casinos is the preferred alternative of players who are looking for social interaction.

In online variations, players get to control the pace of the gameplay. The software often features either Quick Spin or Turbo Mode. This significantly decreases the waiting times between spins.

Many of the roulette tables in landbased casinos are crowded and have higher limits.

The risk of potential dealer mistakes is eliminated. When you play online, you can always rely on a fast and accurate settlement of the payouts, even with more complex multi-chip wagers.

Etiquette is another thing to consider. If you are unable to stick to proper table conduct, landbased roulette may not be the best alternative for you.

Let's not forget about the flexible table limits you can find online. Online casinos are geared toward the needs of both high rollers and roulette players on a shoestring budget. Some gambling sites offer limits that range from as little as a penny to thousands of dollars.

Landbased roulette plays at a leisurely pace and lacks the dynamics of its online cousins. Travel and accommodation expenses should also be taken into consideration.

If you insist on saving on travel and accommodation expenses as well as on the ability to play whenever you want, you are better off with online roulette.

If you are a recreational player who enjoys social interaction and is merely looking to have some fun, landbased roulette may prove to be the better option.
