Gates of Olympus launched in February 2021 on a 6x5 scatter-pay grid where any eight matching symbols anywhere on screen trigger a win. Symbols tumble after each hit, random multipliers between 2x and 500x land on empty positions, and those multipliers stack across the tumble chain. Free spins lock the multipliers for the entire round instead of resetting them between spins. That loop - tumble, collect multipliers, carry them forward - became the single most copied mechanic in online slots within two years.
The game shipped at 96.50% RTP with high volatility and a 5,000x maximum win. Pragmatic Play listed it as a scatter-pay game, but the community shorthand became "Gates formula" or just "tumble multiplier." Providers from Hacksaw to Push Gaming built their own interpretations. None of that changes what the original delivers: a clean, readable bonus round where every spin either adds to the multiplier total or doesn't, and you can track exactly where you stand.
The 1000 treatment
Gates of Olympus 1000 arrived in December 2023 and is the only sequel worth discussing as a genuine upgrade. The "1000 series" treatment tripled the maximum win to 15,000x by inflating multiplier values - random multipliers now reach up to 1,000x instead of 500x. The base mechanic stayed identical. Same 6x5 grid, same scatter-pay tumble, same free spins structure. What changed is the ceiling and the distribution of large multiplier hits during bonus rounds.
Whether the 1000 version is better depends on what you want. Higher ceiling means the game concentrates more value into rarer events. Sessions run longer between meaningful bonus rounds. The original's 5,000x cap produced more frequent medium wins during free spins. The 1000 version trades that consistency for occasional spikes. Both run 96.50% RTP - the math sends the same percentage back, just distributed differently.
Gates of Olympus Xmas 1000 applies the same 1000 treatment with Christmas art and bumps volatility to very high. Gates of Olympus 1000 Dice moves to a 5x4 grid with dice symbols. Neither adds mechanical depth beyond the cosmetic swap and format change.
Platform exclusives: same game, different logo
About fifteen entries in this catalog are operator-branded versions of the original. Gates of Bitcasino, Gates of Betano, Gates of Rizk, Gates of Novibet, Gates of FTN, Gates of Party Casino, Gates of mycasino, Gates of Ozzo, Gates of Toumba, Gates of Leoforos, Gates of Olimpo, Gates of Admiralbet, Gates of Heaven, Gates of Hades - they all run the same 6x5 scatter-pay tumble with the operator's branding layered on top.
The mechanical changes between them range from zero to negligible. Some swap Zeus for a different character. Some adjust the color palette. A few touch the RTP: Gates of Heaven runs an unusually generous 98.00%, while Gates of Admiralbet and Gates of Olimpo sit at 95.50%, and 888 of Olympus drops to 94.50%. Gates of LeoVegas 1000 combines the 1000 treatment with a 94.00% RTP - the worst return in the series by a margin.
These exist because Pragmatic Play sells exclusivity to operators. A casino gets "its own" Gates of Olympus, markets it as unique content, and players who search for that casino's version land on the operator's site instead of a competitor's. It's a distribution strategy, not a creative one. The games play identically to the original except for the handful with altered RTPs - and those alterations always favor the house.
Gatot Kaca and Aztec: theme swaps that add one mechanic
Gates of Gatot Kaca moved the formula from Greek mythology to Indonesian folklore and added a wild symbol - the one feature the original deliberately excluded. The wild doesn't transform the game. It substitutes for paying symbols during tumble chains, occasionally extending a sequence that would have ended. The 1000 version followed in March 2024 with the expected multiplier inflation.
Gates of Aztec did the same swap into Mesoamerican art. Same 6x5 grid, same scatter-pay tumble, same 96.50% RTP, same 5,000x cap. The feature set matches the original exactly. If you played Gates of Olympus blindfolded, Gates of Aztec would feel identical.
Pachi: the one genuine experiment
Gates of Olympus Pachi shrinks the grid to 3x3 and replaces the scatter-pay tumble with a pachinko-style drop mechanic. Balls fall through a pin field, land in multiplier buckets, and trigger respins. It shares the Zeus branding and not much else. RTP drops to 96.04%, max win stays at 5,000x, and the gameplay has more in common with a crash game than a traditional slot.
Pachi is the only entry that genuinely feels different. Whether "different" means "better" is debatable - the pachinko mechanic removes the multiplier-stacking tension that makes the original work. But at least it tried something.
The RTP spread tells the real story
The original Gates of Olympus sits at 96.50%. Most theme-swapped and 1000 variants match that number. But the platform exclusives scatter across the RTP spectrum in ways that matter: 98.00% (Heaven), 96.50% (most), 95.50% (Admiralbet, Olimpo, Hades, Party Casino), 94.50% (888 of Olympus), 94.00% (LeoVegas 1000).
A 4.00% RTP gap between the best and worst versions of functionally the same game is significant over any meaningful number of spins. Gates of Heaven at 98.00% returns roughly twice the edge to the player compared to Gates of LeoVegas 1000 at 94.00%. Same tumble. Same multipliers. Same Zeus. Completely different math underneath. The cards in the catalog above show these numbers - use them before picking which version to load.
