Fireball Roulette: The Complete Guide (Rules, Boosters, Bonus Grid & Live Stats)

Fireball Roulette is Evolution's single-zero roulette variant that marks 3 to 7 numbers as Bonus Numbers each round, lets Fireballs attach 2x to 20x boosters to some of them, and sends a lucky Straight Up bettor into a 149-pocket bonus grid worth up to 2,500x. Straight Up returns a theoretical 97.00%; every other bet returns 97.30%. Our tracker has logged 219,491 rounds as of 2026-08-28. Watch it live on the Fireball Roulette tracker.

What is Fireball Roulette and how does a round work?

Fireball Roulette is a live single-zero roulette game made by Evolution, not Playtech, first appearing on operator lobbies in April 2025. It plays on a real wheel with a live dealer, and it adds two layers on top of standard roulette: a set of numbers marked before the spin, and a bonus grid mini-game that only certain bettors enter.

A round follows a fixed sequence. Bets close, then a virtual slot machine marks between 3 and 7 numbers on the layout as Bonus Numbers. Fireballs then rain down and attach a booster of 2x to 20x to some of those Bonus Numbers, leaving the rest unboosted. Only after that does the physical wheel spin.

1. Betting window. Chips go down on any standard roulette bet before the timer runs out.
2. Bonus Numbers marked. A virtual slot selects 3 to 7 numbers on the layout; you cannot bet on them specifically because betting has already closed.
3. Fireballs strike. Some Bonus Numbers get a booster of 2x, 3x, 4x, 5x, 7x, 10x, 15x or 20x; the rest keep none.
4. The wheel spins. A live dealer spins the physical wheel exactly as on any European table.
5. Settlement. Regular bets pay their standard odds. If the winner is a Bonus Number and you held a Straight Up chip there, the Fireball Bonus grid plays out before you're paid.

A round runs roughly 45 to 50 seconds from open bets to settlement, longer when the bonus grid triggers. The wheel carries no memory: which numbers get marked, which get boosted and where the ball lands are independent draws every time. A full walkthrough of the interface and betting screen is on our how to play Fireball Roulette page.

How many Bonus Numbers appear, and what do Fireball boosters change?

Most rounds mark 3 or 4 Bonus Numbers, and our 90-day data (84,583 rounds) shows the split runs 3 numbers in 30.66% of rounds, 4 in 29.05%, 5 in 23.12%, 6 in 11.43% and 7 in 5.76%. That averages out to 4.33 Bonus Numbers per round, which implies an 11.69% theoretical chance that whichever number the wheel lands on is one of them.

Bonus Numbers per round	Share of rounds (90 days)
3	30.66%
4	29.05%
5	23.12%
6	11.43%
7	5.76%

A Fireball booster only matters for the numbers it lands on, and it only pays out if that number also wins with a Straight Up bet on it. Across 365,889 Bonus Numbers drawn in 90 days, 87.32% carried no Fireball at all, and the rest split across eight fixed values: 2x in 4.06% of draws, 3x in 4.02%, 4x in 1.88%, 5x in 1.26%, 7x in 0.75%, 10x in 0.46%, 15x in 0.20% and 20x in just 0.05%. Evolution never issues 6x, 8x or 9x; those eight values are the complete set.

Booster	Share of Bonus Numbers drawn
None	87.32%
2x	4.06%
3x	4.02%
4x	1.88%
5x	1.26%
7x	0.75%
10x	0.46%
15x	0.20%
20x	0.05%

The winning number itself carried a booster in only 1.46% of rounds, averaging a 68-spin gap between such events with a 433-spin longest wait. When it did happen, the booster's median value was 3x, the average 3.86x, the 90th percentile 7x and the maximum 20x, seen eight times in 90 days: 2026-07-16, 07-18, 07-27, 08-09, 08-11, 08-15, 08-17 and 08-18. The all-time record is also 20x, first logged on 2026-01-21.

None of those booster numbers are the bonus-grid payout. Our tracker's multiplier column records only the 1x-to-20x Fireball, since the casino.org feed does not expose the 30x-to-500x grid result, so a 20x reading in our data is the biggest booster we have seen, never the biggest win. The mechanics of the grid itself, and what the booster does to it, are covered on our Fireball Bonus page.

What bets can you place and what do they pay?

Every bet on a standard European roulette layout is available, and only Straight Up carries a reduced payout and a shot at the bonus grid. The table below lists odds on a 37-pocket wheel alongside the payout Fireball Roulette actually pays.

Bet	Numbers covered	Probability per spin	Payout	Can trigger the bonus grid
Straight Up	1	2.70%	25:1	Yes, if the number is a Bonus Number
Split	2	5.41%	17:1	No
Street	3	8.11%	11:1	No
Corner	4	10.81%	8:1	No
Line	6	16.22%	5:1	No
Column / Dozen	12	32.43%	2:1	No
Red/Black, Odd/Even, 1-18/19-36	18	48.65%	1:1	No

Straight Up's 25:1 is ten units lighter than the 35:1 paid on classic single-zero roulette, and that gap is exactly what pays for the Fireball Bonus feature. Every other bet type keeps its ordinary payout and probability; splits, corners, dozens and even-money bets are never boosted and never enter the grid, no matter how many Bonus Numbers they cover. A player who never bets Straight Up is, in effect, playing plain European roulette with extra numbers flashing on the layout.

How does the Fireball Bonus grid game work?

The Fireball Bonus grid only plays when the winning number was marked as a Bonus Number and you had a Straight Up chip on it; a ball then launches into a field of 149 multiplier pockets. Regular pockets hold values from 30x to 500x, and DOUBLE pockets double every value on the entire grid and relaunch the ball, repeating until a Regular pocket is finally hit or every value has reached the 2,500x cap.

If the triggering number carried a Fireball booster of 2x to 20x, that booster then multiplies whatever the grid produces, still bounded by the same 2,500x ceiling. A Bonus Number with no Fireball simply pays the grid result as it lands, and a Straight Up win on a number that was never marked as a Bonus Number just pays the flat 25:1 with no grid involved at all.

Because the casino.org feed we collect from does not carry the grid's 30x-500x result, we cannot report real payout figures for triggered bonus rounds, only how often the feature fires and what booster (if any) rode along with it. Our bonus-rounds guide walks through the grid's DOUBLE mechanic and booster stacking in more depth.

What is Fireball Chaser, and is it worth the cost?

Fireball Chaser is an optional side bet that automatically places a chip on every Bonus Number as soon as they're revealed, costing roughly 13.6 times your chip size per round. It converts an uncertain, number-specific chance into a fixed-cost bet on the entire batch of marked numbers.

Without Fireball Chaser, a single Straight Up chip only triggers the bonus if that exact number is both marked as a Bonus Number and wins. That works out to (4.33/37)/37, about 0.32%, or roughly 1 spin in 316. With Fireball Chaser covering every Bonus Number, the trigger chance rises to the table-wide 11.69% theoretical figure (11.39% observed over 90 days), an average of 8.8 spins between triggers with a 90-day longest gap of 96 spins.

That is a large jump in frequency, but Fireball Chaser is priced to match it: 13.6 chips buys coverage of, on average, 4.33 numbers, and the side bet does not alter the underlying RTP built into the grid. It simply trades a rare, cheap shot at the bonus for a more frequent, more expensive one. Whether that trade suits you is a bankroll and entertainment question, not an edge question; there is no version of the game where covering more numbers beats the published return.

What is the RTP and house edge of Fireball Roulette?

Straight Up returns a theoretical 97.00% (a 3.00% house edge), and every other bet returns 97.30% (a 2.70% house edge), identical to standard European roulette. The two numbers exist because Straight Up's payout was cut specifically to fund the Fireball Bonus grid.

Bet type	Theoretical RTP	House edge
Straight Up	97.00%	3.00%
Split, Street, Corner, Line	97.30%	2.70%
Column, Dozen	97.30%	2.70%
Red/Black, Odd/Even, 1-18/19-36	97.30%	2.70%

The arithmetic shows where the missing points come from. A Straight Up bet wins 1 spin in 37; at 25:1 that alone returns about 70.3% of stakes (25 divided by 37, plus the returned stake). The remaining roughly 26.7 points of RTP come from the Fireball Bonus grid, spread across every round where a Bonus Number wins with a Straight Up chip on it. Because our data cannot see the grid's actual 30x-2,500x results, we cannot verify that split round by round, only trust Evolution's published figure and confirm that nothing in the wheel's behavior contradicts it.

Operators typically cap total payout at 500,000 per player per round, and bet minimums and maximums vary by site; check the table limits before you sit down, since Straight Up ceilings are usually set lower than outside-bet ceilings. Our Fireball Roulette RTP page tracks these figures against what the wheel actually produces.

How do real Fireball Roulette results compare with the theory?

Across 84,583 rounds in the last 90 days, the physical wheel showed no bias: zero landed 2.63% of spins against a 2.70% theory, red hit 48.75% and black 48.62% against a theoretical 48.65% each, and the three dozens split 32.48%, 32.56% and 32.33% against 32.43% in theory. The hottest numbers were 12 (2.83%), 27 (2.79%) and 19 (2.79%); the coldest were 17 (2.58%), 3 (2.61%) and 24 (2.62%), all well inside normal variance for a sample this size.

The bonus feature lined up with theory too. The winning number was a Bonus Number in 11.39% of rounds (9,636 of 84,583), against an 11.69% figure implied by the average 4.33 Bonus Numbers per round. Of those triggers, 87.16% (8,399) carried no Fireball booster on the winning number, and 12.84% (1,237) did, matching the roughly 1-in-8 rate you would expect from the booster-share table above.

Since our first recorded round on 2026-01-07, the tracker has accumulated 219,491 rounds, with 40,184 in the last 30 days alone. Volume is fairly steady through the day, peaking between 13:00 and 16:00 UTC. If you want to know how likely a long stretch without any bonus trigger is, the observed 11.4% per-round rate implies roughly an 8.9% chance of 20 straight rounds with no Bonus Number winning at all, falling to about 0.2% over 50 straight rounds; the 96-spin longest gap in our 90-day window sits well past that. All of these figures update live, alongside the current bonus drought, on our Fireball Roulette live stats page.

How should you manage your bankroll in Fireball Roulette?

Pick a loss limit before you sit down, size each bet as a small fraction of it, and choose between Straight Up and outside bets based on how much variance you want rather than on which numbers just got marked. That single habit does more for a session than any staking pattern.

Weigh the 0.30-point RTP gap honestly. Straight Up's 97.00% versus 97.30% elsewhere is a real but small difference; it matters over thousands of spins and barely at all over a single evening. Choose Straight Up for the shot at the bonus grid, not because it returns more.

Budget for the trigger rate you're actually playing. A lone Straight Up number triggers the bonus roughly once in 316 spins; Fireball Chaser raises that to about once in 8.8 spins for 13.6 chips a round. Pick the one whose cost per session you can absorb, not the one that feels more exciting in the moment.

Treat droughts as ordinary, not overdue. The longest 90-day gap between any bonus trigger was 96 spins, and the longest gap specifically for a boosted winning number was 433 spins. Neither number changes on the next spin; the odds reset every round regardless of how long the wait has been.

Bet flat. Doubling after a loss (Martingale) or after a win does not change the built-in 2.70% or 3.00% edge; it only changes how quickly a losing streak drains the bankroll you set aside.

What are the most common Fireball Roulette mistakes?

The costliest mistakes in this game come from mixing up its two separate multiplier layers and from treating a marked number as something you can still bet on.

Confusing the Fireball booster with the bonus-grid payout. A 20x reading anywhere in our data, or on screen, is the booster attached to a Bonus Number, not what the 149-pocket grid eventually paid. The grid itself runs 30x to 2,500x, and it only fires at all if you had a Straight Up chip on the right number.

Trying to bet on a Bonus Number after it's marked. Bonus Numbers are revealed only once betting has closed, so there's no way to react to them; whatever chips you already placed are what settle the round.

Assuming 35:1 on Straight Up wins. Players used to standard roulette budget for the classic payout and find their bankroll draining faster than expected, since a non-bonus Straight Up win here pays 25:1.

Chasing a "due" bonus after a long gap. A 90-spin wait without any Bonus Number winning does not raise the odds on the next spin. Raising your stake to "catch up" only increases what's at risk at the same fixed probability.

Skipping Fireball Chaser's cost-benefit check. Adding the side bet every round without comparing its roughly 13.6-chip cost to your usual Straight Up stake can quietly outspend the bet it's meant to support.

Where can you play Fireball Roulette, and is it legal?

Fireball Roulette is available only through online casinos licensed to carry Evolution's live catalogue, and it is legal only where online casino gaming is regulated and you meet the local minimum age, typically 18 and sometimes 21. There is no standalone Fireball Roulette app; every operator streams the same table from Evolution's live studio network.

What changes between operators is the currency, the bet range, any per-round payout cap and the terms attached to deposit bonuses; live roulette variants are frequently excluded from wagering requirements, so check the terms before opting in. A licensed operator must publish the RTP figures, provide deposit and loss limits, and offer self-exclusion tools.

Evolution's own description of the game, including the full payout and RTP table, sits inside the game client's help menu and on Evolution's Fireball Roulette page. Fireball Roulette sits alongside other Evolution multiplier variants such as Lightning Roulette and Lightning Storm, each funding its extra feature by trimming a different payout; comparing them is a useful way to see how the same 2.70% base edge gets reshaped. If gambling stops being entertainment, our Responsible Gambling Observatory tracks drought and volatility data across every game we cover, and every licensed operator lists a national helpline.

Frequently asked questions

How does Fireball Roulette work?

After bets close, a virtual slot marks 3 to 7 numbers as Bonus Numbers, and Fireballs attach 2x to 20x boosters to some of them. The physical wheel then spins as normal. If the winning number is a Bonus Number and you had a Straight Up bet on it, you enter the Fireball Bonus grid game; any other winning bet simply pays its standard roulette odds.

What is the RTP of Fireball Roulette?

Evolution rates Straight Up bets at 97.00% and every other bet at 97.30%, the same figure as standard European roulette. The 6-point cut from the reduced 25:1 Straight Up payout funds the Fireball Bonus grid, while outside bets and inside bets other than Straight Up are untouched by the feature and keep ordinary single-zero odds.

How much does the Fireball Bonus game pay?

The bonus grid holds 149 pockets: Regular pockets pay 30x to 500x, and DOUBLE pockets double every value on the grid before relaunching the ball, up to a 2,500x cap. Our tracker cannot report actual bonus-grid results because the feed only records the 2x-20x Fireball booster, not the grid's 30x-2,500x payout.

Is Fireball Chaser worth it in Fireball Roulette?

Fireball Chaser costs roughly 13.6 times your chip size and automatically covers every Bonus Number, turning an 11.69% theoretical chance of the winning number being a Bonus Number into a guaranteed stake on all of them each round. It raises your bonus-trigger frequency but does not change the underlying house edge; it simply trades a lower per-spin cost for a lower per-hit variance.

Is Fireball Roulette rigged?

Our 90-day data shows no bias: zero landed 2.63% against a 2.70% theory, red and black each landed within 0.15 points of 48.65%, and the bonus-trigger rate was 11.39% against an 11.69% theoretical figure. Evolution runs the game under its own gaming licenses with an RNG deciding Bonus Numbers and boosters, and the wheel is a physical, dealer-spun table.
