Gates of Olympus

Gates of Olympus — the slot that beat Sweet Bonanza

Released in 2021, Gates of Olympus is the slot that nearly dethroned Sweet Bonanza in spin volume. Zeus appears, drops multipliers, and 500x scatters appear at the rate of approximately once per 700 spins.

How the tumble engine pays

Gates of Olympus abandons paylines entirely: eight or more matching symbols anywhere on the 6-reel grid pay, winning symbols vanish, and replacements tumble in for potential chain wins. Zeus supplies the volatility. Multiplier orbs worth up to 500x land on any spin, and in the free spins round (four scatters, or the 100x-stake bonus buy) their values add to a running total multiplier that never resets for the rest of the bonus — the accumulation mechanic that makes deep bonus rounds so explosive and everything else so barren. The Ante Bet option raises the stake in exchange for more scatter frequency, effectively letting you pay for volatility tuning.

The RTP-variant warning — in numbers

This is the game to be careful about which version you are playing. Our database lists the headline 96.50% RTP alongside three certified lower variants: 95.50%, 94.50% and 94.03%. The same slot at 94.03% keeps an extra £2.47 of every £100 wagered compared with the top version, with identical graphics and identical marketing. Nothing on the loading screen tells you which one you have — open the in-game information panel at your casino and check before you play.

What the rest of the data implies

At extreme volatility with a 23.6% hit frequency, Gates is punishing but not Nolimit-punishing: it pays more often than San Quentin xWays (19.2%) or Mental (18.3%), and its 5,000x cap is correspondingly modest next to their six-figure ceilings. The closest sibling is Sweet Bonanza 1000 — same Pragmatic Play tumble DNA, same variant problem, but a 25,000x cap and slightly higher headline RTP (96.53% against 96.50% here, splitting hairs). Choose Gates for steadier accumulation-style bonuses, the Bonanza for a bigger but rarer ceiling.

Bankroll-wise, treat the accumulating multiplier for what it is: a reason bonus rounds vary wildly in outcome, not a mechanism that builds up across a session. Base-game spins between bonuses are where money quietly goes; at the £0.20 minimum you can see enough spins for the maths to breathe, and the Ante Bet’s extra cost should come out of the same fixed budget, not on top of it.
