Gates of Olympus (often shortened to "GOO") has been one of the most-played slots in the world since its 2022 release from Pragmatic Play. A Greek mythology theme (Zeus and his multipliers), a tumble mechanic (cascading wins), free spins with multipliers up to x500, and a max win of 5,000x your stake. It's an iconic slot of Pragmatic's new generation, in the same family as Sweet Bonanza but with more variance and bigger multipliers.
This is a full Gates of Olympus review: the official RTP (96.50% on the high version), bankroll strategy, and where to play it in 2026.
TL;DR — Gates of Olympus in 4 points
- Pragmatic Play slot, 2022, tumble mechanic, RTP 96.50% (high version) or 88.50% on low versions — avoid those.
- High variance: few mid-sized wins, but potential for 5,000x your stake on a single free spin with an x500 multiplier.
- Bonus buy: you can buy the free spins for 100x your stake. Bonus buy RTP is ~96.5%, roughly identical to the base game.
- Available at 90% of the casinos we track, including our top 5: SpinAura, BetRiviera, Millioner, BetMac.
Gates of Olympus mechanics
Cluster pays + tumble
Like Sweet Bonanza, GOO uses a tumble mechanic with no paylines. You win when 8 identical symbols appear anywhere on the 6x5 grid. Winning symbols disappear, empty cells refill — triggering a chain reaction.
Zeus multipliers
During the base game, multiplier bombs (x2 to x500) drop randomly. If you win while a multiplier is present, your win gets multiplied.
During Free Spins, multipliers are much more frequent and add up over the round. Stacking several x100s or x500s can produce a massive payout.
5,000x max win
That's lower than Sweet Bonanza's x21,100, but the hit rate on the max win is higher. At a €1 stake, the max win is €5,000. At €10, it's €50,000.
Gates of Olympus RTP — the 5 versions
Like every Pragmatic title, GOO exists in 5 versions with different RTPs. Check which one you're on at your casino:
| Version | RTP | Recommendation |
|---|---|---|
| High | 96.50% 🏆 | Play this one, no question |
| Standard | 95.50% | Acceptable |
| Low-mid | 94.50% | Moderate |
| Low | 92.50% | Avoid |
| Very Low | 88.50% | Avoid entirely |

Gates of Olympus strategy
Bankroll management
GOO runs high variance (higher than Sweet Bonanza). We recommend a max stake of 0.5-1% of your bankroll per spin. On a €200 bankroll, that's a max stake of €1-2/spin.
Triggering the Free Spins
4 Zeus scatters trigger the free spins. Hit rate is roughly 1 in 250 spins on average (rarer than Sweet Bonanza's ~1 in 200). If you go 250 spins without a trigger, switch slots or buy the bonus.
Bonus buy: 100x your stake
GOO's bonus buy is one of the market's most popular. RTP ~96.5%. Huge variance: 80% of buys return under €100, 5% return €1,000-5,000.
Gates of Olympus vs Sweet Bonanza
| Criteria | Gates of Olympus | Sweet Bonanza |
|---|---|---|
| High-version RTP | 96.50% | 96.48% |
| Max win | 5,000x stake | 21,100x stake |
| Variance | Very high | High |
| FS hit rate | ~1/250 | ~1/200 |
| Max multiplier | x500 | x100 |
| Theme | Greek mythology | Sweet candy |
Takeaway: Sweet Bonanza has a higher max win (21,100x), but GOO delivers bigger multipliers per round (x500 vs x100). Mostly an aesthetic choice.

5,000x your stake per spin. At a €1 stake, the max win is €5,000. At €10, it's €50,000. Very rare (roughly 1 spin in 10,000,000) but possible.
Gates of Olympus or Sweet Bonanza — which should you pick?
Equivalent RTPs (96.50% vs 96.48%). Pick GOO if you prefer Zeus multipliers (x500) and the mythology theme. Pick Sweet Bonanza for the bigger max win (21,100x) and the candy theme.
Is the GOO bonus buy worth it?
100x your stake for 10 FS. RTP ~96.5%. Risky: 80% of buys return less than you paid. Reserved for players with a bankroll that can absorb 5-10 consecutive losing buys.
What's the best RTP version of GOO?
96.50% (high). Confirm you're playing this version at your casino, not the 88.50% one. On SpinAura, BetRiviera, Millioner and BetMac, the 96.50% version is confirmed.
How much bankroll do I need to play GOO properly?
At least 100 times your stake (vs 50 for Sweet Bonanza, since GOO runs higher variance). At a €1/spin stake, that's a €100 minimum bankroll. At €5/spin, €500 minimum.
Does GOO count fully toward wagering requirements?
Yes, at 100% on most casinos. It's a classic Pragmatic slot eligible for standard welcome bonuses.
Is there a "Gates of Olympus 1000" version?
