Potion of Madness

What kind of game is Potion of Madness?

This game shows Dr. J experimenting with a suspicious potion and slowly turning into Mr. H, right on the reels. The core feature is that a different effect triggers depending on whether 1, 2, or 3 or more scatters land. If you like a classic gothic horror mood among Play’n GO slots, this one is a good fit.

What is the transformation feature from 1 scatter?

When 1 scatter lands, the transformation feature triggers and Dr. J symbols across the reels turn into wilds. Even outside free spins, wilds appear all at once, which sets the stage for big wins. The screen suddenly flooding with wilds from just one scatter keeps the base game tense. The more Dr. J symbols on a spin, the bigger the transformation effect.

When does the 2-scatter respin end?

With 2 scatters the respin feature starts and wilds stick to the reels. Respins continue until no new wilds land, and the more wilds that chain together, the more the screen turns toward Mr. H. From the moment 2 scatters appear, there is a thrill in watching how long the respins will last. Thanks to the persistent sticky wilds, the longer the respins run, the higher the win potential.

How does the screen change in free spins?

With 3 or more scatters, free spins open, the reels expand to 5×6, and paylines increase to 40. All Dr. J symbols turn into wilds, greatly increasing your winning chances. Bonus buy is not available. With the wider screen and extra lines, it plays at a completely different scale from the base game. The more Dr. J symbols you see, the more wilds there are, so free spins have the widest range of results.

What should I check first in the demo?

RTP is 96.2% and the max win is 6,000x your bet. There is no official volatility figure, so use the demo to get a feel for how often the 1-scatter and 2-scatter effects appear. Tracking how many respins in a row you get will show you the rhythm. Also compare how different the screen feels once it expands to 5×6 in free spins.
