Gates of Olympus by Pragmatic Play — Full Review

Gates of Olympus, released by Pragmatic Play in February 2021, is a 6x5 scatter-pays slot set on Mount Olympus with Zeus as the central character. It became the #1 most played slot globally for two consecutive years (2022-2023), won Slot of the Year at the CasinoBeats Game Developer Awards 2022, and is available across 600+ operator brands worldwide.
The game introduced what would become Pragmatic Play's most successful formula: scatter pays + tumble + accumulating multiplier orbs. Where Sweet Bonanza (June 2019) pioneered the scatter-pays tumble concept with per-tumble multiplier bombs that reset each spin, Gates of Olympus added the crucial innovation — multiplier orbs that accumulate into a permanent Global Multiplier during Free Spins.
This formula spawned a franchise: Gates of Olympus 1000 (December 2023, orbs up to 1,000x, 15,000x max win), Gates of Olympus Super Scatter (April 2025, 50,000x max), and Gates of Olympus Xmas 1000. The core mechanic has also been replicated across Pragmatic Play titles including Starlight Princess and Zeus vs Hades.
Understanding Gates of Olympus is essential context for the modern scatter-pays ecosystem. It is the game that proved the accumulating multiplier model — and every Pragmatic Play scatter-pays title since builds on its foundation.

How Does Gates of Olympus Actually Work?
Gates of Olympus uses a 6x5 grid (30 positions) with Scatter Pays — no paylines, no ways-to-win, no cluster requirements. To win, you need 8 or more identical symbols anywhere on the grid. Position does not matter.
After every win, the Tumble feature activates: winning symbols explode, remaining symbols drop, new symbols fill from above. Tumbles continue with no limit until no new wins form.
Multiplier Orbs (2x-500x)
Orbs appear alongside regular symbols on any spin. Each carries one of 15 possible values:
2x, 3x, 4x, 5x, 6x, 8x, 10x, 12x, 15x, 20x, 25x, 50x, 100x, 250x, 500x
Multiple orbs are ADDED together (not multiplied). A 50x + 100x = 150x total, not 5,000x.
Base Game vs Free Spins — The Critical Difference
Base game: Orbs apply to the current tumble only. After the cascade ends, the multiplier resets to 1x. Most base game wins are paid at 1x.
Free Spins (Global Multiplier): Every orb is permanently added to a running Global Multiplier that never resets during the entire bonus. A 5x orb on spin 1, a 10x on spin 5, and a 50x on spin 12 = 65x Global Multiplier applied to every subsequent win. This accumulating model creates rising tension: early spins build the multiplier, later spins cash it in.
This is fundamentally different from Sweet Bonanza, where multiplier bombs reset each tumble — each spin is independent. In Gates of Olympus, every orb permanently raises the stakes for all remaining spins.


Core Features
- Scatter Pays (8+ anywhere)
- Tumble/Cascade
- Multiplier Orbs (2x-500x)
- Free Spins (15 spins)
- Accumulating Global Multiplier
- Buy Feature (100x)
- Ante Bet (+25%)
Symbol Values and Paytable for Gates of Olympus

All payouts are per total bet. Gates of Olympus uses Scatter Pays — 8+ matching symbols anywhere on the 6x5 grid (30 positions).
| Symbol | 8-9 Symbols | 10-11 Symbols | 12+ Symbols |
|---|---|---|---|
| Crown | 10x | 25x | 50x |
| Hourglass | 2.5x | 10x | 25x |
| Ring | 2x | 5x | 15x |
| Chalice | 1.5x | 2x | 12x |
| Red Gem | 1x | 1.5x | 10x |
| Purple Gem | 0.8x | 1.2x | 8x |
| Yellow Gem | 0.5x | 1x | 5x |
| Green Gem | 0.4x | 0.9x | 4x |
| Blue Gem | 0.25x | 0.75x | 2x |
Zeus Scatter Payouts
| Scatters | Payout | Bonus |
|---|---|---|
| 4 Zeus | 3x total bet | + 15 Free Spins |
| 5 Zeus | 5x total bet | + 15 Free Spins |
| 6 Zeus | 100x total bet | + 15 Free Spins |
Note: The Crown at 50x for 12+ symbols is the highest-paying regular symbol. With a large accumulated Global Multiplier, even mid-tier gem wins produce significant returns.
Free Spins Trigger Conditions and Payouts



Free Spins trigger when 4, 5, or 6 Zeus Scatter symbols land anywhere on the grid. The game always awards 15 Free Spins regardless of scatter count (the payout differs: 3x/5x/100x total bet).
Trigger frequency: approximately 1 in 448 spins (0.22% per spin). With Ante Bet active (+25% cost), this improves to ~1 in 224 spins. This is significantly rarer than Book of Dead (1/177) or Big Bass Bonanza (1/183), and slightly rarer than Sugar Rush (1/323).
At $0.20/spin: average cost to bonus = $89.60. With Ante Bet ($0.25/spin): $56.00.
How the Global Multiplier Builds
| Spin | Event | Orbs | Global Multiplier | Base Win | Paid Win |
|---|---|---|---|---|---|
| 1 | 8 Blue Gems | 3x | 3x | 0.25x | 0.75x |
| 2 | No win | 5x | 8x | — | — |
| 3 | 10 Green Gems | — | 8x | 0.90x | 7.20x |
| 5 | 8 Red + tumble | 50x + 10x | 68x | 1.50x | 102x |
| 6-10 | Mixed small wins | 15x + 4x | 87x | 3.20x | 278.40x |
| 11 | 12 Crowns! | 100x | 187x | 50x | 5,000x (capped) |
This example is unrealistically good — most bonus rounds build 10-30x Global Multiplier and return 30-100x total. But it shows why every orb matters: the 3x on spin 1 and 5x on spin 2 may seem trivial, but they compound into the foundation that the 100x orb on spin 11 capitalizes on.
Retrigger
3+ Zeus Scatters during Free Spins = +5 more spins with the same accumulated Global Multiplier. Retriggers are unlimited.

Buy Feature and Ante Bet Value Analysis

Gates of Olympus offers two optional bet modifiers. Neither changes the fundamental 3.50% house edge.
Buy Free Spins (100x bet)
- Cost: 100x your total bet ($20 at $0.20, $100 at $1.00)
- Effect: Instantly triggers 15 Free Spins — bypasses the 1/448 trigger wait
- RTP: ~96.49% (marginally lower than base game)
- Availability: Banned in UK and Germany; disabled in some other jurisdictions
At $1/spin, you would need 448 spins ($448) on average to trigger Free Spins naturally. The 100x buy costs $100 — a significant discount on expected wait. The buy RTP is slightly lower (96.49% vs 96.50%) but the difference is $0.01 per $100 — statistically negligible.
Ante Bet (+25%)
- Cost: +25% added to every bet ($0.20 becomes $0.25)
- Effect: Doubles the Free Spins scatter frequency (~1/224 instead of ~1/448)
- RTP: 96.50% (unchanged)
- Trade-off: Every spin costs 25% more, but bonuses come 2x faster
The Ante Bet is mathematically neutral — same RTP, redistributed variance. More frequent bonuses at higher cost per spin. Compare: Big Bass Bonanza charges +50% for its Ante (more aggressive), while Sugar Rush and Sweet Bonanza match at +25%.
Bankroll Math and Expected Value

Gates of Olympus has a 3.50% house edge — identical to Sugar Rush (3.50%) and close to Sweet Bonanza (3.51%). It is slightly lower than Wanted Dead or a Wild (3.62%).
- At $0.20/spin: average cost to first bonus = $89.60 (448 × $0.20)
- At $1.00/spin: average cost to first bonus = $448.00
- Most bonus rounds return 30-100x — heavily right-skewed
- 5,000x max win probability: approximately 1 in 697,350 spins
Compared to Book of Dead (1/177 trigger, $17.70 average cost at $0.10), Gates of Olympus requires roughly 5x more investment between bonus rounds at comparable bet sizes. But the Global Multiplier mechanic means Gates of Olympus bonuses have higher ceiling potential per round.
The franchise context matters: Gates of Olympus 1000 (December 2023) raises the multiplier cap from 500x to 1,000x and the max win to 15,000x — but with identical RTP, trigger frequency, and paytable. The max win becomes 4x rarer (1/2.75M vs 1/697K). For most sessions, the two versions play identically.
Bankroll Scenario Table
| Bankroll | Bet Size | Bets per Bankroll | Expected Loss per 100 Spins | Avg Spins to First Bonus | Cost to First Bonus |
|---|---|---|---|---|---|
| $50 | $0.20 | 250 | $0.70 | ~448 | $89.60 |
| $100 | $0.20 | 500 | $0.70 | ~448 | $89.60 |
| $100 | $0.50 | 200 | $1.75 | ~448 | $224.00 |
| $100 | $1.00 | 100 | $3.50 | ~448 | $448.00 |
| $200 | $1.00 | 200 | $3.50 | ~448 | $448.00 |
| $500 | $2.00 | 250 | $7.00 | ~448 | $896.00 |
| $1,000 | $5.00 | 200 | $17.50 | ~448 | $2,240.00 |
Expected loss assumes 96.50% RTP (3.50% house edge). "Cost to First Bonus" is the average expected wagering ($bet × 448 spins) — actual results vary enormously due to High volatility. See our slot glossary for term definitions.
Gates of Olympus vs Competing Titles
Gates of Olympus competes against the original versions of Pragmatic Play's scatter-pays lineup and the broader high-volatility market:
| Feature | Gates of Olympus | Sweet Bonanza | Starlight Princess | Wanted Dead or a Wild |
|---|---|---|---|---|
| Developer | Pragmatic Play | Pragmatic Play | Pragmatic Play | Hacksaw Gaming |
| Year | 2021 | 2019 | 2021 | 2021 |

| Win Mechanic | Scatter Pays | Scatter Pays | Scatter Pays | 15 Paylines |
| RTP | 96.50% | 96.49% | 96.50% | 96.38% |
| Volatility | High (5/5) | Medium-High (4/5) | High (5/5) | Very High (4/5) |

| Buy Feature | 100x | 100x | 100x | 80x-400x |
What Sets Gates of Olympus Apart?
- Accumulating Global Multiplier — The defining feature. Sweet Bonanza's bombs reset each tumble; Gates of Olympus orbs accumulate permanently during Free Spins. This creates the most dramatic tension arc of any scatter-pays slot.
- Mechanical simplicity — One feature (accumulating orbs), one bonus (15 Free Spins), no decisions. This clarity attracts both casual and experienced players — and is why it became #1 globally.
- Highest orb ceiling in original series — The 500x maximum orb surpasses Sweet Bonanza's 100x bomb cap by 5x. A single 500x orb during Free Spins can transform an entire bonus round.
- Proven franchise foundation — Gates of Olympus 1000 raises the orb cap to 1,000x and max win to 15,000x; Super Scatter pushes to 50,000x. But the original remains the entry point and the most-played version.
Starlight Princess (2021) uses the exact same mechanic (6x5 scatter pays, tumble, accumulating orbs up to 500x, 5,000x max, 96.50% RTP) with an anime aesthetic. The mathematical models are nearly identical — the choice is primarily aesthetic.
Wanted Dead or a Wild (Hacksaw Gaming) offers a completely different approach: payline-based wins with DuelReels expanding wilds, three selectable bonus modes, and a 12,500x max. More frequent bonuses (1/265) but fundamentally different mechanics.
Are Gates of Olympus Predictor Apps Real?

Gates of Olympus is the most popular online slot globally — which makes it the most targeted for scam content.
"Gates of Olympus Predictor" / "Gates of Olympus Hack"
These do not exist. Every spin uses a certified RNG tested by independent laboratories (GLI, BMM Testlabs, iTech Labs, eCOGRA). The result is determined at the moment you press Spin — no external app can predict or influence it. "Predictor" apps are scams designed to steal your money or install malware.
"Play at 3 AM for Better Payouts"
False. The RNG operates identically at all times. Casino traffic, time of day, and server load have zero effect on the mathematical model. Gates of Olympus pays 96.50% RTP whether it is midnight or noon, regardless of how many other players are active.
"The Game Is Due After a Dry Spell"
False. Every spin is independent. If you have gone 1,000 spins without a bonus, the probability of triggering one on spin 1,001 is still exactly 1/448 (0.22%). The RNG has no memory. This is the gambler's fallacy.
Variable RTP Warning
Gates of Olympus has three RTP configurations: 96.50% (default), 95.51%, and 94.50%. The difference between default and lowest is $20 per $1,000 wagered. Always check the in-game info screen to verify your casino's version.
Who Is Gates of Olympus Actually For?
Gates of Olympus is designed for players who enjoy the accumulating multiplier mechanic — the specific thrill of watching a Global Multiplier build throughout a bonus round, raising the stakes with every orb.
Choose Gates of Olympus if:
- You enjoy rising tension: each orb permanently raises the multiplier for all remaining Free Spins
- You prefer the proven original over the more extreme franchise variants
- You want a more achievable max win: 5,000x at 1/697K vs Gates of Olympus 1000's 15,000x at 1/2.75M
- You value mechanical simplicity — one feature, one bonus type, no decisions required
- You enjoy the Greek Mythology / Zeus theme
Consider alternatives if:
- Higher ceiling (same mechanic): Gates of Olympus 1000 (15,000x max, 1,000x orbs) — same core formula with expanded range
- Higher ceiling (different mechanic): Sweet Bonanza (21,175x) or Wanted Dead or a Wild (12,500x)
- Per-spin independence: Sweet Bonanza — multiplier bombs reset each tumble, making every spin self-contained rather than accumulating
- Position-based multipliers: Sugar Rush — 7x7 cluster pays where grid positions accumulate multipliers (2x-128x) that persist through Free Spins
- More frequent bonuses: Book of Dead (1/177) or Big Bass Bonanza (1/183)
- Same mechanic, different theme: Starlight Princess — nearly identical math in an anime aesthetic

Frequently Asked Questions About Gates of Olympus
What is the RTP of Gates of Olympus?
Gates of Olympus has a default RTP of 96.50%, giving a 3.50% house edge. Operators can configure lower versions: 95.51% or 94.50%. The difference between default and lowest is $20 per $1,000 wagered. Always check the in-game info screen to verify.
What is the difference between Gates of Olympus and Gates of Olympus 1000?
The only mathematical difference is that the 1000 version adds a 1,000x multiplier orb value (the original caps at 500x). This triples the max win from 5,000x to 15,000x but makes it 4x rarer (1/2.75M vs 1/697K). Everything else — paytable, Free Spins, trigger frequency, RTP — is identical.
How does the Global Multiplier work?
During Free Spins, every multiplier orb is permanently added to a running Global Multiplier that never resets. All subsequent wins are multiplied by this accumulated value. In the base game, orbs only apply to the current tumble and then reset. This accumulation is the defining mechanic of Gates of Olympus.
How often do Free Spins trigger?
Approximately once every 448 spins (0.22% per spin). With Ante Bet active (+25% cost), this improves to ~1/224. At $0.20 per spin, expect $89.60 average cost between bonuses; with Ante, $56.00 (at $0.25/spin).
Is the Buy Feature worth it?
The Buy Feature costs 100x your bet and triggers 15 Free Spins. Its RTP is 96.49% — marginally lower than base game (96.50%). The difference is $0.01 per $100 wagered — negligible. It saves the 448-spin average wait. Unavailable in UK and Germany.
What is the max win in Gates of Olympus?
The maximum win is 5,000x total bet. This requires a combination of high-value symbol wins (Crown at 50x for 12+) and a large accumulated Global Multiplier. The probability is approximately 1 in 697,350 spins — rare but 4x more achievable than the 1000 version's 15,000x.
Does bet size affect Free Spins trigger?
No. The trigger probability (1/448) is identical at all bet sizes from $0.20 to $100. Bet size affects only payout amount, not feature frequency. The RNG does not consider bet size when determining outcomes.
Are Gates of Olympus predictor apps real?
No. All results are determined by a certified RNG tested by GLI, BMM Testlabs, iTech Labs, and eCOGRA. No external app can predict or influence outcomes. "Predictor" apps are scams designed to steal money or data.
Should I use the Ante Bet?
The Ante Bet costs +25% per spin but doubles the trigger frequency (1/448 → ~1/224). RTP remains 96.50%. It is mathematically neutral — same expected value, different variance distribution. More frequent bonuses at higher per-spin cost. A bankroll management preference, not a mathematical advantage.
Why is Gates of Olympus so popular?
Gates of Olympus became the #1 most played slot globally (2022-2023) due to its unique accumulating Global Multiplier, simple mechanics, and dramatic tension arc. It won Slot of the Year at CasinoBeats GDA 2022 and is available across 600+ operator brands. The mechanic proved so successful it spawned a franchise (1000, Super Scatter, Xmas variants).
Responsible Gambling Notice: Gates of Olympus is a game of chance with a 3.50% house edge. The house always wins long-term. Set a budget before playing, never chase losses, and never gamble with money you cannot afford to lose. If gambling causes distress, contact BeGambleAware or Gambling Therapy.
