There are no paylines. Eight or more of the same symbol anywhere on the 6x5 grid pays, and the payout scales with how many you land. After a win the paying symbols disappear and the gaps refill from above, so one spin can chain into several wins. Pragmatic calls this tumbling.

The multiplier orbs are where it gets interesting. In the base game an orb can land on any spin with a value from 2x to 500x, and when the tumble sequence ends, every orb on screen is added together and applied to the total win of that spin. Two orbs of 10x and 5x make 15x, not 50x. They add, they don't multiply each other.

The catch is obvious once you think about it. An orb on a spin with no win is worth nothing. Lots of spins look exciting and pay zero.

Bigwinboard rates volatility 5 out of 5. That's the top of their scale, and it matches how the maths is built: small, frequent tumbles, then long dry patches broken by the odd big multiplier.

Four or more scatters anywhere start 15 free spins. This is the round the game is built around, and it scores 8 out of 10 from our editors.

The difference from the base game is memory. Every multiplier orb that lands on a winning tumble sequence gets added to a running total, and that total stays for the rest of the round. So a 10x early on means every later winning spin starts from at least 10x. It only goes up. Retriggers are possible during the round, so a good run can keep building.

Here's the honest bit. A total of 50x is useless if the later spins don't produce wins for it to multiply, and plenty of rounds finish with a small multiplier and small wins. The round is where the big results come from, and it's also where a lot of bets go to die. Both are true.

The bonus buy costs 100x your bet where it's offered. It isn't available in the UK, and the ante bet option depends on jurisdiction too. I'd skip the buy. Paying 100x per bonus burns through a budget very quickly, and no buy changes the fact that every slot has a negative expected value.

Pragmatic Play lists 96.5% on its game page, and that's the figure our score uses. Bigwinboard also lists 95.5% and 94.5% versions, and the casino picks which one it runs. The game looks identical at every setting.

Open the info screen (the 'i' or menu button) and scroll to the RTP line before you put money in. If it says 94.5%, you're paying for the same game at worse odds. Two percentage points sounds small; over thousands of spins it isn't.

And RTP is a long-run average across millions of spins. It tells you nothing about what a one-hour session returns, which can be far above or far below it. Our RTP guide explains the gap between the advertised number and what you'll actually see.

Honestly, the 1000. Both list a 96.5% top RTP, so they tie on the biggest part of the Spin Score. Both get the same 8 for free spins and 7 for the base game. The only difference in the score is max win: 5,000x on the original against 15,000x on the 1000, which lifts the sequel from 7.8 to 8.0.

Where that higher ceiling comes from is the orbs. They go up to 1,000x instead of 500x. The free spins round also gives five extra spins when three scatters land during it, per Pragmatic's description.

One thing in our data looks odd. Bigwinboard rates the original 5/5 but lists the 1000 only as 'High' without a score, so our records show 'very high' for the original and 'high' for the sequel. I wouldn't read that as the 1000 being calmer. With bigger orbs and a higher ceiling, I'd assume it's at least as swingy.

If you already like the original's look and pace, there's no strong reason to stay on it.

Gates of Olympus suits someone who enjoys watching a grid cascade, understands that most spins return less than the bet, and has set a budget they're fine losing. It doesn't suit short sessions on a small balance. Very high volatility means a modest budget can run out before four scatters ever show up.

For a calmer pay-anywhere game, look at the Sweet Bonanza guide, which is rated medium-high rather than top-of-scale. For more of the same mechanic, our tumble slots ranking lines them up by Spin Score. And the six slots ranked above on this page share the cascading, multiplier-led style, from Jammin' Jars at the top to the 1000 sequel.
