Live multiplier roulette games offer enhanced payouts mainly for straight-up bets, but there are games where all inside bets qualify for random multipliers. Their values range between 50x, 150x or even 5,000x, and they get paid when the winning number has one of these multipliers assigned, sometimes in elaborate ways. Winfinity’s Cabaret Roulette includes multipliers on Outside bets.
In this article, we’ll look at all the live roulette games that offer multipliers, and I’ll tell you where you can play them and explain some of the most popular strategies for winning.
You’ll be surprised how many games there are and the crazy ways they bring those multipliers to you!
Since 2020, over a dozen live roulette games with multipliers have been released, showing that these games gained traction with players and are exciting and profitable to play.
Below, we’ll explain how multiplier roulette games enhance the usual roulette experience.
The roulette games with multipliers generally only come to life if you’re a straight-up number player, as in most games, only straight-up bets receive the multipliers. In exchange, the usual payout is reduced from 35:1 to 19:1 – 29:1, depending on the multiplier values in play for the game. Some games allow all inside bets to profit from multipliers, and I’ll point those out as we go.
If you want to play these games and bet on things like Red/Black, you can, and the odds and payouts are the same as in any other roulette game, except for Winfinity’s Cabaret Roulette, which has reduced payouts on all bet types because Outside Bets benefit from multipliers.
If you think a strategy of betting on all numbers would let you catch the huge win multiplier every time, I regret to inform you such a blunt approach doesn’t work.
Different games have different rules, and this bet-all strategy would only be suitable for the most basic roulette multiplier games.
That’s why I invite you to check out the strategy guide for every game on this page, as no blanket strategy would cover all these games.
Live multiplier roulette games have taken casinos by storm and have reinvented the age-old straight-up number betting on roulette numbers.
The often neglected art of picking the correct number on the roulette wheel is now rewarded with win multipliers that are usually 50x but can go much higher, up to 5000x.
In this article, we’ll look at all the live roulette multiplier games and compare them. We’ll also explore some straight-up number betting strategies and systems that you can use to make the most of these multipliers!
If you want to play the games and want maximum excitement, here are the games with the most elaborate bonus rounds and the largest win multipliers.

This confusing title refers to the multiplier roulette games, where a Random Number Generator (computer program) assigns the multipliers to numbers randomly.
So you might see the number 24 get a 50x multiplier. You win if you bet on that number, and the ball stops in that numbered pocket.
These are the basic multiplier roulette games. Later, we’ll describe games that have bonus rounds and other stuff.
This is the game that started it all in 2018.
Lightning Roulette retains a similar house edge to European roulette – 2.90% instead of the standard 2.70% – but it distributes wins on straight-up numbers differently. The standard payout is reduced from 35:1 to 29:1, and the remaining funds, so to speak, are distributed to win multipliers.
There can be up to five Lucky Numbers on any game round, with multipliers of 50x, 100x, 200x, 300x, 400x or 500x. Most of the time, you can expect a 100x multiplier, but of course, you must have an active bet on that number, and the ball needs to land in that pocket!
I must mention that Lightning Roulette is a basic multiplier concept, unlike other games on this list that take things further.
That’s not to say the game is no good – it’s among the most popular games Evolution has ever released. The game is so popular that it made its way to land-based casinos and is the first live dealer game to do that.
This is essentially the same game as the others on this list of basic roulette multiplier games.
Mega Roulette was just an effort by Pragmatic Play to have a roulette multiplier game in the portfolio without providing anything different from its competitors.
The presentation, however, is spectacular, but it’s essentially the same game as Lightning Roulette, three years after the original was released, with an RTP of only 96.50%.
You get up to five multipliers in one round, ranging from 50x to 500x. They hit less often than in the original Evolution game, hence the lower RTP.
In July 2023, an Auto Roulette version was released for players who want a faster game without a presenter.
XL Roulette is Authentic Gaming’s first live roulette game with multipliers.
Authentic has traditionally focused on bringing roulette games that are streamed from actual casino locations but, more recently, has turned to producing studio-streamed games. XL Roulette is their first multiplier roulette game.
Originally released on mobile before being available on desktop, this is four games in one. You get to choose the level of volatility you want to play at.
There are four playing options, three of which produce multipliers. The standard option is the regular European roulette with no multipliers and a straight-up payout of 35:1. The other options are as follows:
Since you aim to get multipliers as soon as you launch this game, it makes sense to go for more multipliers and play the XXL or the XXXL version.
More multipliers reduce the variance – you won’t make money from the straight-up payout anyway; you need multipliers.
RTP of all four options is the same, 97.30%, so it’s only a matter of choosing if you want more multipliers on your wheel or less.
This is a more volatile game. Xxxtreme Lightning Roulette takes the Lightning Roulette concept and upgrades it with more and bigger multipliers. The idea is still the same, but the in-game events can boost the multipliers to 2,000x.
Again, up to five lucky numbers are chosen to receive the multipliers that can now also be 150x, 250x and 350x in addition to the 50x, 100x, 200x, 300x, 400x or 500x from Lightning Roulette.
A random Chain Lightning feature can strike and increase the number of multipliers to 10. A Double Strike with Red Lightning can increase the multipliers to 600x – 2,000x.
In this game, the straight-up payout is 19:1, so in this game, you can only win if you hit the multiplier; otherwise, you’ll be slowly losing money.
The game also has an RTP of 97.10% and a house edge of 2.90%, the same as the standard Lightning Roulette. So it’s only a matter of what kind of volatility you prefer.
In the Spring of 2023, a small live casino developer, ICONIC21, treated us to an absolute gem of a multiplier roulette game. This game offers several small innovations that make a lot of difference.
Gravity Roulette lets you play any inside bet and qualify for the multiplier.
In other games, you have to place a straight-up bet, and here, you can place a Split, Line or Corner bet and still get the multiplier, albeit with a reduced stake.
The multipliers range from 50x to 1,000x, so that’s another upgrade, and the RTP is 97.40, so the game pays better than standard European roulette.
The game is also less volatile than the competitors’ games. The game’s theme draws on the popularity of Quantum Roulette and upgrades that as well.
Finding Gravity Roulette is difficult, but it’s worth tracking down. You’ll find it at Parimatch Casino.
This is Evolution’s replacement for Gold Bar Roulette.
Rather than letting players choose where to place multipliers on the table, Gold Vault Roulette does it for them and delivers between five and twenty 50x multipliers each game round.
Up to three 50x multipliers can be stacked on one number, creating a 150x payout. The multipliers are only available on straight-up bets and usually pay 24:1. The special gold bar pays 500x.
Essentially, this is an upgraded Lightning Roulette. Each Gold Bar has a value of 50x, and the Bars can be stacked up to three to give payouts up to 150x. There is also a special 500x Bar. So, the game offers multipliers from 50x to 500x.
The difference is there are more lucky numbers now, as up to 20 Gold Bars worth 50x each can be assigned to straight-up numbers in each game round.
A Super Gold Bar that pays 500x can land sometimes. To compensate, the straight-up payout is reduced to 24:1. The RTP of this game is 97.03%, so it is lower than the first two multiplier games, but it plays better because you have a physical object to associate the multipliers with.
It’s a slightly less volatile game that doesn’t feel as utterly random as the two Lightning Roulette games.
Lucky 6 Roulette has six randomly assigned multipliers between 50x and 2088x each game round.
Straight-up bets pay 19:1, while the rest use the standard European Roulette paytable.
Ony Straight-up bets qualify for the multiplier payouts.
This is a more volatile roulette game than Pragmatic’s Mega Roulette, which has up to 5 multipliers and a maximum payout of 500x.
If you want a volatile game of multiplier roulette, Big Bang Roulette from Winfinity delivers in spades.
You get between 3 and 15 multipliers each game round. They rain down as fireballs, exploding onto the betting grid, revealing between 50x and 50,000x!
Only available on Straight-up bets, which, if you win without a multiplier, pay the sum of even money, 1:1.
This game is not for the faint-hearted or those who like steady wins.
You win or lose big on Big Bang Roulette. It’s available at Winz Casino.
Ezugi Revolution Roulette is the second live multiplier roulette game in which the multipliers are physically chosen rather than selected by RNG.
Three extra pockets have been added to the roulette wheel, each containing a multiplier, 2x, 3x & 5x.
It’s not a very volatile game, as the multipliers are relatively low, and the payout adjustments are not too brutal. For example, the Straight-up payout pays 28:1.
What’s also very cool is that all Inside and Outside bets benefit from the multipliers, making this a fair and playable game with the outside chance of getting some nice wins.
Expect the multipliers to hit on average every 13 spins. The RTP is 96.65%.
Try it out at Vbet.
The multiplier roulette games in the previous section all have very basic multipliers.
If you get 100x, that’s it. But the games on this list can have the multipliers boosted to a more significant amount.
The most recognizable representative of this subgenre is Quantum Roulette, but Power Up Roulette offers supreme entertainment.
It took Playtech a little over a year to release a multiplier roulette game after Evolution first released theirs, but Playtech included some additional innovation.
Quantum Roulette achieves nothing different as the maximum multiplier is still 500x; it gets you there differently, not by landing a 500x multiplier directly but by having a Quantum Leap double or triple on a multiplier.
There are also up to 5 numbers that can get the multipliers. The presentation is different, and the gameplay is more interesting.
The popularity of this game (and the other Quantum multiplier games) is growing constantly, with different language versions available across the regions.
Pragmatic Play played it safe with the Mega Roulette. Still, their second multiplier release, Power Up Roulette, is a true gem as it offers multipliers up to 8,000x with captivating gameplay.
The innovative Power Up feature, first seen in Boom City, assigns a multiplier boost to all numbers during the Power Up round.
The presentation of this game is excellent; all those shiny multipliers look much more tempting than the occasional multiplier that lands in other games.
The game plays in a way that doesn’t encourage a bet-all strategy, and you feel you have a chance. This is a hugely popular game with an RTP of 97.19%.
This is a complex game with four roulette wheels.
First, you have to hit the number on the first wheel – if you do, you get a 29:1 win. The following three wheels determine if your win will be boosted further and how much.
This enjoyable, complex game has a quantum theme and varying RTP values for different bets. The unique feature is that no RNG is involved in the game. All the selections come from the results of spins from the roulette wheels.
For example, the straight-up bets have an RTP of 97.05%, but the Column bet looks better to me despite the RTP of 95.89%. Read my Nexus Roulette guide to learn to play this game.
This roulette game doesn’t simply boost a multiplier, instead, it has virtual horse, dog or bike races that determine the win multiplier boost for every single round.
Jet Set Racing Roulette is the slowest game on this list, and it can award a win multiplier of 2,499x if you’re lucky and you predict all race winners accurately.
Two roulette wheels are used, and the game has an RTP of 97.29%. This elaborate game will appeal to the very narrow virtual race audience.
Cabaret Roulette does a few things differently from other multiplier games.
Firstly, all Inside and Outside bets benefit from multipliers. The Inside Bets benefit from the start of the game, while a unique Slot Feature triggers the Outside Bets multipliers.
Up to five multipliers are initially assigned to the betting grid with a value up to 1000x.
The Slot Feature can trigger one of three bonuses. The Heart Bonus adds additional multipliers to the betting grid, the Star Bonus adds up to 20 multipliers to the Outside and Inside bet positions, and the 2x Bonus feature doubles all multipliers.
Here are several roulette games that let you buy multipliers.
It’s a clever trick to encourage you to buy multipliers. The initial fee pays for the payouts rather than reducing the usual payouts too much. The extra fees to get more multipliers can result in you losing more as you’re paying to play, and most of the time, you’ll lose. However, these games are structured to give the best payouts for the purchased multipliers.
In all likelihood, the players who don’t buy the feature are getting an inferior deal.
Super Stake Roulette is Stakelogic’s first multiplier roulette game and is also innovative.
There is a bonus round money wheel where you can win multipliers up to 5,000x, but you’ll need to buy the Super Stake option to have a chance to trigger the bonus round.
Up to five multipliers are free and pay between 50x and 750x. You can have five more multipliers that pay 100x to 1,000x, while the money wheel has multipliers between 50x and 5,000x.
In my Super Stake Roulette strategy guide, you’ll find all the necessary information that comes from my experience of playing this game for a while and my video review of the game.
This is one of the better multiplier games out there, possibly the one with the best presentation.
You can get a multiplier up to 5,000x, which automatically sets it apart from other games where the multipliers are more pedestrian.
A 50x multiplier is just a decent win, but 5,000x can have you jumping with joy.
The straight-up payout without the multipliers is 29:1, so StakeLogic succeeded in making a multiplier game that can offer payouts up to 5,000x without reducing the straight-up payout too much.
Ultimate Roulette is the first multiplier roulette game from Ezugi and the third multiplier game they’ve released.
The generic title hides an exciting circus theme and a game that can produce up to 8 multipliers that range from 50x to 1,000x.
This must be one of the most visually impressive live roulette games. It’s thrilling to play.
The first five multipliers are free, but you can ‘buy’ up to three more for eight. Multiplier payouts can range up to 1,000x, but if you’re lucky and have purchased extra multipliers, the maximum multiplier can increase to 2,000x.
The possible values of multipliers are 50x, 100x, 150x, 250x, 500x, 750x and 1,000x. The three additional multipliers you pay for can be doubled if you’re lucky, which is where the maximum 2,000x payout comes from.
In my Ultimate Roulette strategy article, you’ll find all you need to know about whether to buy the additional multipliers.
Finally, we’ll talk about the best of the best – the multiplier roulette games with a bonus round that is triggered that awards larger multipliers.
These are probably the most enjoyable multiplier roulette games to play, and the enjoyment seems proportional to how elaborate the bonus round is.
This remains one of the most popular multiplier games, and not even Evolution managed to make a game that would match Mega Fire Blaze Roulette in terms of sheer fun.
First, the live dealer spins the roulette wheel. It’s not an auto wheel, which makes the game more human. All inside bets qualify for the multipliers, so you can Split, Line, and Corner your way to a massive multiplier—the maximum multiplier is 10,000x.
Up to five Fire numbers are chosen, or up to 10 if a random Fire Blast occurs. Then, if the ball lands on a Fire number, the elaborate bonus round begins.
It is complex, so read my review of the game on the link above. The maximum win here is 10,000x, which is the most enjoyable multiplier game I’ve played.
Bet365 has a Super Spin Roulette game by Playtech that looks like a hybrid between Quantum and Mega Fire Blaze games. It offers multipliers of up to 540x.
This innovative game will let you play the Millionaire bonus round, earning win multipliers by getting the answers correct.
The Who Wants To Be A Millionaire Roulette offers a standard 29:1 straight-up payout; up to 10 numbers can be highlighted.
There are three highlighted number types – a Millionaire Logo will trigger an eight or 10-question bonus round that will pay up to 750x or 2,000x, a 100x multiplier, or a question mark that will let you take a multiplier of 50x or 100x or play the Millionaire bonus round to win up to 150x or 300x.
The game has an RTP of 97.29% and is fun to try out, especially for show fans, even if the ‘questions’ are attempts at guessing the highest number.
Crazy Time is such a popular game that it managed to find its way to roulette, too.
Evolution included the Crazy Time Bonus Round in a multiplier roulette game, Red Door Roulette. Three to fifteen Keys are assigned randomly to the numbers on the roulette betting grid, and some will get multipliers from 2x to 20x.
If the ball lands on one of the Keys, the Red Door Crazy Time bonus round will begin, which can produce wins of up to 4,000x.
Read my Red Door Roulette strategy guide for information on how to play and the strategies commonly used to play.
The second Stakelogic multiplier roulette, after Super Stake Roulette, Runner Runner Roulette, removes the fee that you need to pay to gain access to the top multipliers.
There are still two parts to the game: you can win multipliers of 50x to 500x, but if you trigger the bonus round, you can win 5,000x.
The game has an RTP of 97.30%, the same as the standard European roulette and, therefore, better than all of the Evolution multiplier roulette games.
A bonus round can be triggered when the ball lands on a Star Symbol that has the potential to pay up to 5000x.
Think of it as Lightning Roulette with something extra.
This is OnAir’s first Multiplier Roulette game that uses the RNG to select the numbers and allocate the Multipliers.
Diamond Rush Roulette can have between 1 and 10 multipliers or 50x to 500x every game round. A unique Bonus number, when landed on, triggers a bonus round, which can deliver up to 4999x if the player makes six correct choices.
This game allows the Multipliers and Bonus rounds to be won using all inside bets. Payouts are adjusted according to the bet type, so there’s no need for just Stratight-up betting, which happens to pay 29:1 for regular wins.
The RTP is nicely balanced, with 97.69% for Inside Bets and 97.30% for Outside Bets.
Sticky Bandits Roulette Live is a multiplier game with an optional Side Bet, which qualifies players for the Sticky Bandits Bonus Round.
Unusually, this game only has one Lucky Multiplier, which can boost the payout of a winning number by 2x, 3x or 4x. The maximum payout for a Straight-up number is 119:1.
All Inside bets qualify for the Lucky Multiplier, so you receive a proportion of the full amount depending on the type of bet you’ve placed.
The Side bet costs 7x the chip value you want to use in the bonus round.
It’s possible to play just the roulette game, the bonus bet or both. Conventional wisdom says to play both!
Cash Collect Roulette hits the spot with multipliers and three bonus rounds, which can deliver payouts up to 3000x.
In every game, up to 5 lucky numbers are chosen to have the Bonus rounds, Cash Collect, Diamond Bonus and Coin Power Up attached.
If one of these numbers wins, players with an active bet can play the bonus round. Each Bonus round delivers a range of multipliers – Cash Collect up to 3000x, Diamond Bonus 30x to 500x and Coin Power Up 30x to 225x.
What’s great is that all inside bets qualify for the bonus rounds, with payouts adjusted proportionally to the bet type used to qualify. Straight-up bets get 100%, while a Corner bet will receive 25% of the prize.
Cash Collect is probably one of the best multiplier roulette games with multipliers I’ve played.
Fortune Roulette is a multiplier roulette game with up to six multipliers in each game round and a Bonus Number and Chest feature, which is unique in these games.
The multipliers can reach 540x, while the Bonus round can deliver a payout of 9000x if luck is on your side.
The Chest Feature is the innovation that, when landed on, collects every multiplier on the betting grid and pays that to the lucky player.
It’s possible to get a 3240x payout this way!
All Inside bets qualify so that you can play this game more naturally. Straight-up payouts are 23:1 and the other Inside Bets are reduced from the regular European Roulette paytable, but that’s normal in these types of games.
Vegas Drops Roulette offers players the option to increase their chances of getting the bonus round, where you win multiplier payouts. Of course, there is a cost associated with doing this.
The base game gives you up to 5 red numbers, which can qualify you for the bonus round if you’ve picked one and it is the winning number on the roulette wheel. You can double your chances by playing the Super Stake Bet, which costs you 50% more but gives you five extra gold numbers, which, if picked, will improve the payout you might receive.
Then there’s the Bonus buy feature where you can place a bet on each randomly drawn number. You’re not guaranteed a win, but your chances are improved. The top payout is 4,999x, and only Stratight-up bets (29:1) qualify for the Bonus Round.
Fireball Roulette is a live dealer multiplier roulette game with a bonus round and a maximum payout of 2,500x.
Each game has three to seven bonus numbers. If the roulette ball lands in one of these numbered pockets, the bonus round is initiated, where players can win up to 2.500x. There’s a Fireball chaser bet, which, when placed, will put a chip on each of the bonus numbers when they are selected. This bet costs 13 times your chip amount. While this covers all the bonus numbers, it doesn’t increase the chances of the result being a bonus number.
The Fireball round is taken straight from Lightning Storm and continues Evolution’s strategy of creating games with game show bonus rounds.
While I initially wasn’t a fan of multiplier roulette games, players can’t seem to get enough of them.
It took other operators between a year and two to catch up with the concept after Evolution innovated it in 2018 and between two and four years to start producing their innovative games.
Now, we have almost 20 roulette multiplier games, which are becoming more and more elaborate.
It seems roulette has been turned into a proper live dealer entertainment show!
Multiplier roulette games offer a smaller payout on straight-up bets but potentially much larger single payouts in return.
You get a smaller payout without the multiplier, but then, if lucky, you can get 500x or more on the same bet when the multiplier strikes.
The maximum win multiplier on multiplier roulette games is around 500x, but some games boost this to 2,000x and beyond. The maximum is 10,000x, offered by Mega Fire Blaze Roulette.
The multiplier genre started with random multipliers but has since evolved to produce roulette games with elaborate boosts and bonus rounds.
Some games offer this: Red Door Roulette, Mega Fire Blaze Roulette and Power Up Roulette.
