A roulette game by Playtech

Devriez-vous y jouer ?
Quantum Roulette is for straight up players who want a multiplier chance on every spin. An unmultiplied straight up win pays 29 to 1 instead of 35 to 1, and Playtech publishes one 97.3% return for the game rather than a figure for each bet.
Écoutez-le si
- You bet straight up numbers and want multipliers in play every round
- You enjoy the Boost and Leap moments on a studio table
- You want a single zero wheel
Ne le lisez pas si
- You mainly bet splits, corners or outside bets, which are never multiplied
- You want the standard 35 to 1 straight up
- Long runs of 29 to 1 wins between multiplied hits would wear on your budget
Profil de variance
Élevé. A straight up gives up 6 units on every ordinary win to fund occasional 50x to 500x hits, so straight up results swing hard. Outside bets are untouched and swing as on any single zero table.
How Quantum Roulette works
Place your bets
Bet as on any single zero table. Only straight up bets can collect a Quantum multiplier.
Multipliers strike
Once betting has closed and the ball is spinning, 1 to 5 random numbers get a multiplier from 50x to 500x. A Quantum Boost or Quantum Leap can raise some of them.
The ball decides
A straight up win on a multiplied number is paid its multiplier, up to 499 to 1 in the game rules. Any other straight up win pays 29 to 1.
Where the multipliers land
Quantum Roulette is built on single zero rules. Each round, after betting closes, 1 to 5 numbers are marked with a multiplier. The values used are 50x, 100x, 150x, 200x, 250x, 300x, 400x and 500x; there is no 350x or 450x. The multiplier counts your stake, so a 500x straight up pays 499 to 1. A straight up on a number without one pays 29 to 1.
Only straight up bets are multiplied. If you place a neighbors or sector bet such as Jeu Zero, the straight up chips inside it can be multiplied, but its splits and corners pay their normal amounts.
Quantum Boost and Quantum Leap
Two special events happen at random. A Quantum Boost adds 50 to some or all of the multipliers on the table, so a 100x becomes 150x. A Quantum Leap doubles or triples some or all of them. The Boost came with the 2019 launch; the Leap was added by early 2020. Neither changes which numbers the ball favors: they only raise what a multiplied number pays.
What the 29 to 1 pays for
A standard straight up pays 35 to 1. Here it pays 29 to 1, and those 6 units on every ordinary win are what fund the multipliers. Red, black, odd, even, dozens and columns pay as normal and lose on zero. Playtech’s rules give 97.3% for the game, the same figure a standard single zero table returns, but no separate figure for a straight up once its multipliers are counted. The paytable in the game lists what splits, streets, corners and lines pay at your table.
The same format runs under several names: Quantum Roulette Live, Greek Quantum Roulette, Quantum Roulette Italiana, Quantum Ruleta España, Bucharest Quantum Roulette, Ruleta Automática Cuántica and Virtual Host Quantum Roulette. The Italian version is hosted by native speaking dealers. Each table’s own help screen is the version of the rules that applies there.
The math behind Quantum Roulette
Playtech publishes a 97.3% return for the game as a whole; it does not publish a figure for each bet or how often each multiplier value is drawn. These are the figures that are published.
- Published RTP
- 97.3% for the game
- Roue
- Single zero, numbers 0 to 36
- Straight up pays
- 29 to 1, or 29 to 499 to 1 with a multiplier
- Multiplied numbers
- 1 to 5 straight ups a round
- Multiplier values
- 50x, 100x, 150x, 200x, 250x, 300x, 400x or 500x
- Quantum Boost
- Adds 50 to some or all multipliers
- Quantum Leap
- Doubles or triples some or all multipliers
A straight up bet wins on 1 of 37 pockets (2.70%), and its ordinary 29 to 1 payout returns only 81.08% of what you stake on its own. The rest of a straight up bet's value comes from the 50x to 500x multipliers on 1 to 5 numbers a round and the Boost and Leap events that raise them, and their frequencies are not published.
Try it: place your bets
Tap a number to place a straight up bet; it is the only bet with a published payout here. The other boxes are shown for reference.
The green pocket is not red, black, odd, even, high or low, so every outside bet loses when it lands. That is where the house edge comes from.

Your chance, payout and cost per spin will show here. Over many spins these bets lose about a spin on average, of your stake, even though a single spin leaves you ahead of the time. These bets can never finish a spin ahead, only break even or lose, and over many spins they lose about a spin on average, of your stake. A winning straight up pays 29 to 1, which on its own gives back 81.08% of what you stake; the bonus games add more, but how much is not published, so the true cost of these bets is not known.
The spread and biggest win show the ordinary 29 to 1 only; bonus game wins are left out.

Is there a Quantum Roulette strategy?
No. The multipliers appear only after betting closes and land on random numbers, so there is no way to bet a number for its multiplier, and Playtech's 97.3% is one figure for the whole game.
The multiplier comes after the bet
Up to five numbers are lit once the ball is already spinning. A multiplied number is no likelier to win; each keeps its 1 in 37 chance.
Call bets get part of the feature
A neighbors or sector bet such as Jeu Zero is multiplied only on its straight up chips. Its splits and corners pay their normal amounts even when they cover a multiplied number.
What you can control
Straight ups or the rest
Only straight ups can win a multiplier, and every ordinary straight up win pays 29 to 1. If you would rather not pay for the feature, red, black, dozens and columns pay as normal.

Quantum Roulette FAQ
How do Quantum Roulette multipliers work?
After betting closes, 1 to 5 random numbers get a multiplier of 50x to 500x. If the ball lands on one and you have a straight up bet on it, you are paid the multiplier instead of 29 to 1.
What do Quantum Boost and Quantum Leap do?
They are random events that raise the multipliers. A Quantum Boost adds 50 to some or all of them; a Quantum Leap doubles or triples some or all of them.
What does a straight up pay in Quantum Roulette?
29 to 1 on a number without a multiplier. The game rules list 29 to 499 to 1 for a straight up once multipliers are included.
Are Greek, Italian and Spanish Quantum Roulette the same game?
They run under the same Quantum name and format, with multipliers on straight up numbers, but each is its own table with its own dealers and help screen. Check the rules shown on the table you join.
How often does a Quantum Roulette straight up win a multiplier?
Your number wins 1 time in 37. Whether it carries a multiplier when it does depends on how many numbers are lit, 1 to 5, and the rules do not say how often each count or value comes up.
Is Quantum Roulette cheaper than standard roulette?
No. Playtech’s rules give 97.3% for the game, the same as a standard single zero table. The multipliers are paid for by cutting ordinary straight up wins from 35 to 1 to 29 to 1, not added on top.
