Gates of Olympus Roulette RTP, Payouts & House Edge: What the 20:1 Straight-Up Buys
By LiveCasinoData editorial team · Updated 2026-08-28 · 14 min read
Pragmatic Play states Gates of Olympus Roulette returns 97.30% on every bet type, though that uniform claim comes from secondary sources rather than the game's own rules screen. The straight-up bet pays a reduced 20:1 instead of the standard 35:1, with Lucky Number multipliers of 50x to 250x and a Bonus Number worth up to 10,000x meant to close the gap. Our tracker has logged 1,566 rounds since capture began on 2026-08-27, still too small a sample to test the RTP claim itself, though early hit rates and the number spread already sit close to theory.
Key takeaways
- Pragmatic Play states a 97.30% RTP for Gates of Olympus Roulette, reported in secondary sources as uniform across bet types, a claim we could not confirm against Pragmatic's own rules screen.
- A straight-up bet pays 20:1 instead of the standard European 35:1, a cut that alone would return only about 56.76% before any Lucky Number or Bonus Number feature is added.
- In our first 1,566 tracked rounds, 261 (16.67%) carried some form of multiplier win, and the Bonus Number itself hit 51 times, 3.26% of rounds.
- The average multiplier on a hit was 128.6x, with a recorded high of 1,291x on 2026-08-28, both far below the stated 2,500x base-game and 10,000x bonus-round ceilings.
- The table is only about 1.8 days old as of 2026-08-28, so none of the observed rates on this page should be read as a settled long-run figure.
Pragmatic Play states Gates of Olympus Roulette returns 97.30% on every bet, matching standard European roulette. Straight-up bets pay a reduced 20:1 rather than 35:1, and Lucky Number multipliers plus a Bonus Number slot-style bonus round are meant to make up the difference. Our tracker has logged 1,566 rounds of Gates of Olympus Roulette since capture began on 2026-08-27; this page checks what that reduced payout buys and what the first day of data shows.
What is the RTP of Gates of Olympus Roulette?
Pragmatic Play publishes a 97.30% RTP for Gates of Olympus Roulette. Several third-party game guides describe that figure as applying uniformly across every bet type, straight-up included, setting this game apart from Evolution's Lightning Roulette, where a variant's straight-up and outside bets are not always priced identically. We have not verified the "same RTP everywhere" claim against Pragmatic's own rules screen, only against secondary sources, so it belongs in the reported column rather than the confirmed one.
A 97.30% RTP is a 2.70% house edge, if the published figure holds as described: for every 100 units wagered over a very long run, the game is designed to return 97.30 and keep 2.70. That average is hard to observe this early. The tracked history for this table is 1,566 rounds spanning under two days, nowhere near the volume needed to test a percentage that only settles down over tens of thousands of spins. The RTP monitor compares theoretical and observed return across our tracked games once enough history exists; this table is not listed there yet.
Why does a straight-up bet pay only 20:1?
Standard European roulette pays 35:1 on a straight-up. With 37 pockets, the expected return on that bet alone is (1/37) x 36, which is 97.30%, matching the whole game's RTP with no other feature required. Gates of Olympus Roulette cuts the straight-up payout to 20:1, a figure drawn from secondary guides rather than confirmed on Pragmatic's own rules screen, and worth treating as provisional until that primary source is checked. On its own, 20:1 returns (1/37) x 21, which is 56.76%, an edge north of 43% that no one would accept as a standalone bet.
The gap between 56.76% and the stated 97.30% blanket figure is roughly 40.5 percentage points, over double the size of the gap Lightning Roulette closes with its 29:1 payout, about 16.2 points. The larger cut lines up with a much larger stated ceiling: Lightning Roulette tops out at 500x, while Gates of Olympus Roulette advertises up to 2,500x in the base game and 10,000x through its bonus round. A bigger headline prize needs a bigger slice taken from the base payout to fund it.
Every other bet on the layout is untouched, since only a straight-up can carry a Lucky Number multiplier or trigger the Bonus Number's round. The strategy page covers when giving up those 15 units of payout on a plain win is worth the multiplier upside.
What does every bet pay in Gates of Olympus Roulette?
Probability and payout for every bet, drawn from the standard European layout Gates of Olympus Roulette uses:
| Bet | Numbers covered | Probability per spin | Payout | Notes |
|---|---|---|---|---|
| Straight-up, no Lucky/Bonus hit | 1 | 2.70% | 20:1 | reduced from standard 35:1 (verify exact figure) |
| Straight-up, Lucky Number hit | 1 | 2.70% x chance the number is Lucky that round | 50:1 to 250:1 | multiplier drawn before the spin |
| Straight-up, Bonus Number hit | 1 | 2.70% x 1-in-37 chance the number is the Bonus Number | slot bonus round, up to 10,000:1 | triggers Gates of Olympus free spins |
| Split | 2 | 5.41% | 17:1 | standard European payout |
| Street | 3 | 8.11% | 11:1 | standard |
| Corner | 4 | 10.81% | 8:1 | standard |
| Line | 6 | 16.22% | 5:1 | standard |
| Dozen | 12 | 32.43% | 2:1 | standard |
| Column | 12 | 32.43% | 2:1 | standard |
| Red / Black | 18 | 48.65% | 1:1 | standard |
| Odd / Even | 18 | 48.65% | 1:1 | standard |
| 1-18 / 19-36 | 18 | 48.65% | 1:1 | standard |
Every row from split downward matches a normal single-zero table, since none of them can carry a Lucky Number or Bonus Number payout. A split's expected return is (2/37) x 18, which is 97.30%, and the same product holds for every multi-number bet. Reading the 20:1 figure alone as the whole story is the natural mistake; the Lucky Number and Bonus Number mechanics sit on top of it.
How do Lucky Numbers, the Bonus Number and the Super Booster change what a straight-up bet pays?
Before each spin, the game assigns up to seven Lucky Numbers, each with its own multiplier, plus one separate Bonus Number. Our data shows between two and seven Lucky Numbers assigned per round, averaging 4.94, matching Pragmatic's "up to seven" description. If a straight-up bet is on a number made Lucky that round and it wins, it pays that number's assigned multiplier instead of the base 20:1.
Pragmatic describes Lucky Number multipliers as running "up to 250x." Our data shows the values are drawn from a small fixed set rather than a continuous range: 50x, 100x, 150x, 200x, 250x. The table below counts how often each value was assigned across the sample, regardless of whether the number went on to win.
| Assigned multiplier value | Times assigned | Share of assignments |
|---|---|---|
| 50x | 4,037 | 57.0% |
| 100x | 2,540 | 35.9% |
| 150x | 338 | 4.8% |
| 200x | 129 | 1.8% |
| 250x | 33 | 0.5% |
The distribution is heavily weighted toward the low end: over nine in ten Lucky Number assignments were 50x or 100x, so the typical Lucky Number payout sits closer to the bottom of the "up to 250x" range than the top.
The Bonus Number is a separate slot, one number per round, not drawn from the Lucky Number pool. If it wins with a straight-up bet on it, the round moves into a Gates of Olympus bonus round, 15 free spins with accumulating multipliers borrowed from the slot game, capable of paying up to the stated 10,000x. Full mechanics are on the bonus round page; this page stays focused on payouts.
On some rounds, a feature called Super Booster applies an extra 2x-10x factor on top of the Bonus Number's and a random selection of Lucky Numbers' assigned multipliers. That is what raises the stated base-game ceiling to 2,500x: a high Lucky Number value multiplied again by a high booster factor. Super Booster occurred on 28 of 1,566 rounds in our sample, 1.79%, and the factors observed so far are narrower than the official 2x-10x range.
| Super Booster factor | Rounds observed |
|---|---|
| 2x | 12 |
| 3x | 10 |
| 5x | 6 |
No 4x boost or anything from 6x to 10x has shown up yet across those 28 rounds, which is not evidence those factors are rare, only that they have not appeared in this slice of the data.
Does our early data match the win-type mechanics Pragmatic describes?
Our stored round data tags every spin with a win_type field that says exactly which mechanic produced its payout multiplier. Across the first 1,566 rounds, the breakdown is:
| Win type | Rounds | Share |
|---|---|---|
| Regular number, no Lucky or Bonus hit | 1,305 | 83.33% |
| Lucky Number hit (plain) | 193 | 12.33% |
| Bonus Number hit, no booster | 40 | 2.55% |
| Lucky Number hit, Super Booster active | 17 | 1.09% |
| Bonus Number hit, Super Booster active | 11 | 0.70% |
Add the four non-regular rows together and a straight-up bet carried some kind of multiplier on 261 of 1,566 rounds, 16.67%, close to a rough estimate of about 16% built from 4.94 Lucky Numbers averaging 13.4% of the 37 pockets plus the separate 1-in-37 Bonus Number slot. The match is encouraging, but this remains a rough, early-sample estimate, not a confirmed design rate.
Multiplier size varies sharply by mechanic.
| Win type | Average | Median | Min | Max | Rounds |
|---|---|---|---|---|---|
| Lucky Number (plain) | 77.7x | 50x | 50x | 250x | 193 |
| Bonus Number (no booster) | 202.1x | 183.5x | 105x | 488x | 40 |
| Lucky Number + Super Booster | 202.9x | 150x | 100x | 500x | 17 |
| Bonus Number + Super Booster | 637.8x | 420x | 226x | 1,291x | 11 |
Across all 261 non-regular rounds, the average multiplier was 128.6x, median 100x. The gap between a plain Lucky Number hit, averaging under 80x, and a boosted Bonus Number hit, averaging over 600x, shows how much of the upside sits behind the rarer combinations.
How volatile is a straight-up bet in Gates of Olympus Roulette?
A straight-up bet is far more volatile than an outside bet, and than a straight-up in standard roulette, since part of its return arrives through rare multiplier and bonus-round events rather than a flat 35:1 every time it wins.
| Bet | Win rate | Typical payout | Chance of no win in 37 spins | Volatility |
|---|---|---|---|---|
| Red / Black, Odd / Even | 48.65% | 1:1 | effectively zero | Low |
| Dozen / Column | 32.43% | 2:1 | under 0.001% | Low |
| Line | 16.22% | 5:1 | 0.1% | Low-medium |
| Corner | 10.81% | 8:1 | 1.5% | Medium |
| Street | 8.11% | 11:1 | 4.4% | Medium |
| Split | 5.41% | 17:1 | 12.8% | Medium-high |
| Straight-up | 2.70% | 20:1, sometimes 50:1 to 10,000:1 | 36.3% | Very high |
The win probability for a straight-up bet is unaffected by the Lucky Number or Bonus Number machinery, still 1 in 37, so the 36.3% chance of a total blank across 37 consecutive spins is identical to a standard table. What differs is the shape of the wins that land: 83.33% of our straight-up wins paid the plain 20:1, and the remaining 16.67% ranged from a 50x Lucky Number up to the 1,291x combination described above.
What is the maximum win in Gates of Olympus Roulette?
Pragmatic's marketing states two ceilings. In the base game, without triggering the bonus round, the maximum is 2,500x, reached when a Lucky Number carrying the 250x value also gets a Super Booster boost. Through the bonus round itself, triggered by landing on the Bonus Number with a straight-up bet on it, the stated maximum is 10,000x, the Bonus Number's multiplier stacked with a Super Booster and the free-spin round's own accumulating wins.
Neither ceiling has come close to being tested, which is expected given the table is only about 1.8 days old. The largest multipliers recorded so far:
| Multiplier | Number | Mechanism | Date |
|---|---|---|---|
| 1,291x | 26 | Bonus Number + Super Booster (3x) | 2026-08-28 |
| 1,128x | 22 | hit twice | 2026-08-27 |
| 816x | 31 | 2026-08-27 | |
| 588x | 29 | 2026-08-27 | |
| 500x | (two separate hits) | plain Super Booster Lucky Number | 2026-08-27 |
All of these sit well under a tenth of the stated 10,000x ceiling. That gap will close as more rounds accumulate; a single Bonus Number hit with a high Super Booster factor is enough to reset the record on any spin, regardless of how long it has been since the last one.
Does the number distribution show any bias yet?
Not so far, though the sample is early enough to be a starting point rather than a settled result. Across 1,566 rounds, zero landed 50 times, 3.19% of spins, close to the theoretical 2.70% for a single pocket on a 37-number wheel. The single busiest number in the sample landed in about 3.90% of rounds, also within the range a fair wheel can produce this early.
A gap of a percentage point or so between the busiest number and theory is routine noise at 1,566 rounds. Evolution's much larger Lightning Roulette sample of nearly 100,000 spins narrows to under two tenths of a point across all 37 numbers, and this table should compress toward that same tightness as its history grows, since the Lucky Number and Bonus Number features are assigned independently of where the ball lands.
How often do the multiplier features hit, and how long are the gaps between them?
Across the first 1,566 rounds, the average gap between any Lucky or Bonus Number hit was 6.0 rounds, longest 37. The Bonus Number specifically is rarer: average gap 30.2 rounds, longest 127, shortest 1, meaning it once landed on consecutive spins. As of 2026-08-28, the table is 56 rounds into its current Bonus Number drought.
A 56-round gap sounds notable against a rate that would predict one roughly every 31 rounds, but the longest gap already seen, 127 rounds, is more than double the current one, and it sits well inside what a random process produces regularly. The Bonus Number is drawn fresh each round with no memory of how long it has been absent, so neither the current drought nor any future one changes the odds on the next spin. The bonus round page covers the trigger mechanics in more depth.
How do you read the RTP and multiplier stats on our tracker?
The live tracker includes a probability calculator that turns observed hit rates into session-length odds. Using the combined 16.67% hit rate, the chance of a straight-up bet seeing zero multiplier hits across 10 spins is 0.8333 to the 10th power, about 16.2%. Using the Bonus Number's own 3.26% rate, the chance of hitting it at least once across 30 spins is 1 minus 0.9674 to the 30th power, about 62%. Both lean on an early sample and will shift as more rounds come in.
The drought tracker on the same page shows how long it has been since the last Lucky Number hit and the last Bonus Number hit, the figures cited above. The hot and cold panel shows number frequency, currently close to flat given the small sample. For a full walkthrough of every widget, including how the feed updates and what a single round record contains, see the live-stats guide.
Is a "live RTP" figure meaningful yet for this table?
No, less so here than for almost any other game we track. A short-window observed return describes what already happened, not a forecast, since each spin draws independently from the same pockets and Lucky Number pool. With only 1,566 rounds of history, a single 1,291x hit like the one on 2026-08-28 is large enough to swing a short-window reading by a huge margin on its own, and a run of plain 20:1 wins right after it would swing the reading the other way just as fast.
That volatility settles down only with volume, which this table has not had time to build. Until the sample runs into the tens of thousands of rounds, any observed percentage quoted here is a snapshot of a short window, not a check on Pragmatic's stated 97.30%. The fairness index folds return-tracking into a broader score once a game has enough history.
None of this changes what a sensible session looks like. The house edge, whatever its exact final value turns out to be, applies to every spin regardless of recent results, droughts or hot numbers. Set a budget before sitting down, treat the multipliers as occasional upside rather than something owed after a quiet stretch, and use the Responsible Gambling Observatory for session limits.

Frequently asked questions
What is the RTP of Gates of Olympus Roulette?
Pragmatic Play publishes a 97.30% RTP, matching standard European roulette. Secondary game guides describe this as applying uniformly to every bet type, straight-up included, but that specific claim has not been confirmed against Pragmatic's own in-client rules screen, so it should be treated as reported rather than verified. The tracked history for this table is currently too small to test the figure independently.
Why does Gates of Olympus Roulette pay only 20:1 on a straight-up bet?
A 20:1 payout alone returns about 56.76%, roughly 40.5 percentage points short of the stated 97.30% target. Lucky Number multipliers of 50x to 250x and a Bonus Number worth up to 10,000x are built to close that gap. The reduced base payout funds a far higher ceiling than a standard roulette straight-up, which is why the cut is larger than on Evolution's Lightning Roulette.
What is the maximum win in Gates of Olympus Roulette?
Pragmatic's marketing states up to 2,500x in the base game, reached when the Super Booster feature boosts a Lucky Number, and up to 10,000x through the Gates of Olympus bonus round triggered by the Bonus Number with a Super Booster stacked on top. Our tracker's highest recorded multiplier so far is 1,291x, on 2026-08-28, well under either ceiling given only about two days of history.
How often do the Lucky Numbers or Bonus Number hit?
In our first 1,566 rounds, a straight-up bet on the winning number would have carried some multiplier 16.67% of the time, and the Bonus Number specifically hit 51 times, 3.26% of rounds. The average gap between any Lucky or Bonus Number hit was 6.0 rounds; the average gap between Bonus Number hits specifically was 30.2 rounds. Treat both rates as early estimates, not confirmed design odds.
Is Gates of Olympus Roulette RTP the same as Lightning Roulette?
Both are stated at 97.30%, but the games get there differently. Evolution's Lightning Roulette prices straight-up bets slightly below outside bets in its XXXtreme variant and funds a 500x-2,000x ceiling with a smaller payout cut. Gates of Olympus Roulette, a Pragmatic Play game, reportedly applies 97.30% uniformly and funds a much higher stated ceiling with a deeper cut to the straight-up payout, 20:1 against 29:1.
