It’s hard not to do a double take when the title Gates of Hades pops up, especially if you’ve spent time with the now-famous Gates of Olympus. Yes, this slot game draws some inspiration from that earlier hit, but it doesn’t lean on it too heavily. This one trades scatter pays for cluster wins, throws in sticky wild multipliers, and builds tension across a 6x6 grid. In the world of online slots, that’s a noticeable shift, and one that lets this game carve out its own space.
Pragmatic Play doesn’t shy away from familiar mythological turf, and Hades is as ominous as ever. He stands to the side, smirking while the grid spins beside him, framed by lava tones and stormy flashes. It’s atmospheric enough without reinventing the wheel, just enough to tell you this is Olympus’ dark sibling, not its twin.
Wins are formed through clusters of 5 or more symbols connected vertically or horizontally. Payouts increase based on the size of the cluster, up to 36 symbols.
Symbol | Payouts for 5, 10, and 15–36 of a kind |
Blue Gem | 0.10x, 0.50x, 10x |
Green Gem | 0.20x, 0.80x, 15x |
Orange Gem | 0.30x, 1x, 20x |
Yellow Gem | 0.40x, 1.50x, 24x |
Purple Gem | 0.40x, 1.50x, 36x |
Red Gem | 1.50x, 6x, 90x |
Heart Pendant | 2x, 9x, 120x |
Ring | 2.50x, 12x, 240x |
Goblet | 3x, 21x, 300x |
Wilds aren’t just for substitution, they come with attached multipliers ranging from x1 to x100 in the base game. When a wild lands and forms part of a potentially winning cluster, its multiplier is added to the reel’s total multiplier. Each cluster win is then multiplied by the combined total of those multipliers. Once all tumble wins finish, the multipliers clear.
Free spins are triggered by landing 3 or more scatter symbols. The number of spins awarded increases based on how many scatters land: 10 spins for 3, 12 for 4, 15 for 5, and 20 if 6 or more hit. Here’s the twist: if you trigger the feature with 6 or more scatters, it becomes a "super free spins" round where all wilds have a minimum x10 multiplier.
During the free spins, any wild multipliers that land stay sticky on their respective reels until the round ends. This can lead to some heavy stacking if they keep lining up with clusters. And yes, multipliers in this round can reach as high as x500. Retriggers are possible too: land more scatters during the bonus to potentially add up to 12 additional free spins.
The game plays on a 6x6 grid using a cluster pays system. Instead of paylines, potential wins are awarded when five or more identical symbols are connected in a block. The tumble mechanic clears away winning clusters, allowing new symbols to drop into place for another shot at a potential win. This continues until no new wins are formed.
If the Hades vibe or the cluster mechanic grabs your attention, there are a few other online slots that might be worth comparing:
Gates of Hades plays like the more strategic sibling to Gates of Olympus. The move to cluster pays and the addition of wild multipliers means you’re dealing with more calculation and chaining potential. It’s a clean evolution, though not a revolutionary one, and the retention of wild multipliers during free spins is a solid touch. Nothing here is radically new, but the mechanical layering gives it a bit more bite.
