Hades by Yggdrasil drops a 6×6 Gigablox grid into the Greek underworld with progressive multipliers up to x10 and an 11,129x cap.
Yggdrasil released Hades back in October 2020, and it's still one of the moodier entries in the Gigablox catalogue. The 6×6 grid sits inside a stone cabinet flanked by snake-and-skull columns that drip lava, with the lord of the underworld himself standing to the right of the reels, glowing emerald eyes and all. It's a hellish-baroque look that commits hard to the theme. The intro cinematic, with Hades smirking through violet-blue skin and ember sparks, sets the tone before you've even tapped spin.
Math-wise you're looking at 96.0% RTP, medium-high volatility, 50 fixed paylines, and a hit frequency around 20.5%. Bets run from 0.10 to 100 per spin. The headline number is the 11,129x max win, which isn't astronomical by 2026 standards but felt punchy when this dropped.
The two mechanics doing the heavy lifting are Gigablox and Wild Hunt. Gigablox lands oversized symbols in 2×2 up through 6×6 formations, and they count as individual icons for line wins. Scatters can also arrive Gigablox-sized, which is where the bigger Free Spins triggers come from. Wild Hunt fires every base-game spin, where Hades picks a fight with high-pay symbols and converts winners into Wilds for that spin. There's no organic Wild on the strips, so every Wild you see is something he just defeated.
Free Spins kick in with 5 or more Scatters, awarding spins equal to the scatter count. Inside the bonus, a progressive multiplier climbs as Hades collects Wild conversions. Hit 10 Wilds for x2, another 15 for x3, 20 more for x5, and a final 25 for the x10 ceiling, with each tier also adding 2 free spins. Gigablox Wilds count by their full footprint, so a 3×3 conversion banks 9 toward the next threshold.
One gripe, honestly: there's no Buy Bonus, which feels like a missed feature for a 2020 release that leans this hard on its bonus round. You'll grind base spins to find the trigger, and at medium-high variance that can take a while. Still, when Wild Hunt cooks during a x10 free-spin tier, the math actually delivers on the dread the artwork is selling. Worth a session if dark mythology slots are your thing.
