With its dark atmosphere and exciting features, Potion of Madness offers a truly unique experience.

Mr. H takes on the role of the wild, stepping in for all symbols except the scatter. Landing five wilds on a payline pays up to 30x. As for the Potion of Madness scatter, it doesn’t wait around for company, it can trigger features even when just one shows up on the screen.

Potion of Madness packs in a few clever mechanics that shake up the base game and unlock bigger win potential through wild transformations, sticky symbols, and expanding reels.
When a single Potion of Madness scatter lands, it transforms all visible Dr. J symbols into wilds. Two scatters take things up a notch by triggering respins. Here, Dr. J symbols turn into sticky wilds with the potential to expand vertically. Only one wild can land per reel, and respins keep going as long as wilds keep expanding, new ones show up, or there’s still space for more.
Landing three Potion of Madness scatters awards five free spins and expands the grid to 6 rows high, bumping the paylines up to 40. During this round, any Dr. J symbol that lands turns into a wild with a chance to expand. Every time a wild lands or grows, it kicks off a respin. Only one respin session happens per free spin, but within that, the same wild-expanding rules apply - spins keep coming until no more space is left.
If you’re a fan of the dark and eerie world of 19th-century horror literature, Dr. Jekyll and Mr. Hyde by Betsoft offers a similar theme, diving into the duality of human nature. Dr. Frankenstein from Rubyplay also taps into the horror genre, with its own unique take on classic monsters. If you enjoy features like expanding wilds, try Starburst by NetEnt, a fan favourite with vibrant symbols and expanding wilds, or Crystal Lotus from Eyecon, which also brings expanding wilds into play while focusing on a mystical, gem-filled world. All of these games are available to explore at Smooth Spins.
