Helluva Slot — RTP, volatility and max win

GameArt packs Helluva Slot into a compact hell slot where devils, demons, a joker and hellish beauties appear among skulls, flames and card suits. A wild that expands over its reel triggers a respin, and sticky wilds stay put for the spins that follow.

The theme mixes hell with playing cards: devils and demons, a grinning joker, seductive hellish ladies, skulls and flames, plus classic card suits. Its small 3×3 reel set has 5 paylines, keeping the game as easy to follow as a classic. For such a compact grid the bet range is unusually wide, from €0.05 to €100 a spin. GameArt released Helluva Slot on May 6, 2025.

5 paylines cross the 3×3 grid. A line pays when matching symbols sit on it across all three reels, and several line hits in one spin are added up. With so few positions, wilds make the difference: an expanding wild covers a whole reel and becomes part of every line running through it. The payout depends on the symbol and on the bet you set, from €0.05 to €100.

Wilds carry Helluva Slot: an expanding wild fills its reel and starts a respin, respin wilds trigger further repeat spins, and sticky wilds stay on the grid over several spins. Random and fixed multipliers can raise wins. Bonus icons lead to a prize wheel and a separate bonus round, which you can also buy outright. After a regular win there is a gamble option where you can double the amount or lose it.

Since expanding wilds in Helluva Slot trigger respins, the remaining inferno slots with respins are where to look next.
