Double ball roulette
Double Ball Roulette is a live casino game in which two balls are launched simultaneously into the same roulette wheel instead of one. The result is two winning numbers per round, a wider range of betting options, and the possibility of a 1,300:1 jackpot payout when both balls land on the same number.
What Is Double Ball Roulette?
Double Ball Roulette takes the standard European roulette wheel and adds a second ball. Both balls are launched at the same time, spin independently, and land on separate numbers — giving you two results from a single spin. This changes the betting structure significantly: inside bets only require one of the two balls to win, while outside bets require both balls to satisfy the condition.
The game was developed by Evolution Gaming and is available exclusively as a live dealer title. It uses a genuine physical wheel with a real croupier, making it part of the same category as Dragonara Roulette and other premium live formats.
How the Mechanism Works
The two-ball mechanic is not a digital simulation — it is a real physical system. A compressed air mechanism is built into the wheel track. When the croupier presses a button, two balls are fired simultaneously through a tube directly into the spinning wheel. Both balls travel the same track but independently of each other, so they decelerate and drop into pockets at different moments and different positions.
The result is two genuinely independent outcomes per spin. Neither ball influences the other. In statistical terms, each ball has a 1 in 37 chance of landing on any specific number — exactly the same as in standard European roulette.
Bets and Payouts
Double Ball Roulette uses a modified payout structure to account for the two-ball mechanic. The critical rule to understand: inside bets win if either ball lands on your number. Outside bets win only if both balls satisfy the condition. This asymmetry is the core of the game’s strategy.
Inside Bets — One Ball Needed to Win
For inside bets, you only need one of the two balls to land on your selection. Because you have two chances instead of one, the payouts are adjusted downward compared to standard roulette — but your win probability is roughly double.
| Bet Type | Covers | Payout (1 ball) | Payout (both balls) |
|---|---|---|---|
| Straight Up | 1 number | 17:1 | 35:1 |
| Split | 2 numbers | 8:1 | — |
| Street | 3 numbers | 5:1 | — |
| Corner | 4 numbers | 3.5:1 | — |
| Line | 6 numbers | 2:1 | — |
Outside Bets — Both Balls Must Win
Outside bets work differently. For red/black, odd/even, high/low, dozens, or columns to pay out, both balls must land within your selection. Because the condition is harder to meet, outside bets pay significantly more than in standard roulette.
| Bet Type | Condition | Payout |
|---|---|---|
| Red / Black | Both balls same colour | 3:1 |
| Odd / Even | Both balls odd or both even | 3:1 |
| High / Low | Both balls in same half | 3:1 |
| Dozen | Both balls in same dozen | 8:1 |
| Column | Both balls in same column | 8:1 |
The Double Ball Jackpot
The standout feature of Double Ball Roulette is the Golden Bet — a straight-up wager that pays 1,300:1 if both balls land on the same number you selected. This is the only bet in the game where having both balls on exactly the same pocket matters.
The probability of both balls landing on the same specific number is 1/37 × 1/37 = 1/1,369, or approximately 0.073%. The 1,300:1 payout is slightly below the mathematically fair odds of 1,368:1, which is where the house edge on this bet comes from. It is a low-frequency, high-reward wager — comparable in structure to a progressive jackpot side bet.
House Edge and RTP
Despite the modified betting structure, Double Ball Roulette maintains the same house edge as standard European roulette: 2.70%, with an RTP of 97.30%. The two-ball mechanic and adjusted payouts are mathematically balanced so that the casino’s advantage per euro wagered remains identical.
| Game | House Edge | RTP | Wheel |
|---|---|---|---|
| Double Ball Roulette | 2.70% | 97.30% | European (37 pockets) |
| European Roulette | 2.70% | 97.30% | European (37 pockets) |
| French Roulette (La Partage) | 1.35% | 98.65% | European (37 pockets) |
| American Roulette | 5.26% | 94.74% | American (38 pockets) |
This makes Double Ball Roulette a fair choice mathematically — the added complexity and jackpot feature come without any penalty to the base house edge. For a deeper understanding of how the house edge works across different variants, see our house edge guide.

Frequently Asked Questions
How does Double Ball Roulette work?
Two balls are launched simultaneously into a standard European roulette wheel using a compressed air mechanism. Both balls spin independently and land on separate pockets, producing two winning numbers per round. Inside bets win if either ball lands on your selection; outside bets win only if both balls satisfy the condition.
What is the payout for a straight-up bet in Double Ball Roulette?
A straight-up bet pays 17:1 if one ball lands on your number, and 35:1 if both balls land on your number. If both balls land on the same number you selected, you also qualify for the 1,300:1 Golden Bet jackpot.
What is the Golden Bet in Double Ball Roulette?
The Golden Bet pays 1,300:1 when both balls land on exactly the same number you wagered on. The probability is 1 in 1,369 per spin (approximately 0.07%). It is the highest single-spin payout available in the game.
Does Double Ball Roulette have a higher house edge?
No. Despite the added complexity, Double Ball Roulette uses a European wheel and maintains a house edge of 2.70% — identical to standard European roulette. The adjusted payouts for both inside and outside bets are calculated to preserve the same mathematical advantage for the casino.
Why do outside bets pay more in Double Ball Roulette?
Because outside bets require both balls to satisfy the condition, which is significantly harder to achieve than with a single ball. Red/black, for example, requires both balls to land on the same colour — a probability of roughly 23.6% compared to 48.6% in standard roulette. The 3:1 payout compensates for this lower win rate while maintaining the 2.70% house edge.
Where can I play Double Ball Roulette?
Double Ball Roulette is an Evolution Gaming exclusive and is available at any licensed online casino that carries Evolution’s live dealer library. It is a live-only format — no free-play RNG version exists. Check our live roulette guide for recommended platforms.
Is Double Ball Roulette the same as Double Zero Roulette?
No — these are two completely different games. Double Ball Roulette uses a European single-zero wheel with two balls launched per spin. Double Zero Roulette (American Roulette) uses a single ball but adds a second green pocket (00) to the wheel, raising the house edge to 5.26%. The names are similar but the games have nothing in common.
