The story here goes like, during the day Mr H is a brilliant scientist, but when dark falls he drinks one of his portions and turns into a monster, and goes into a rampage only to find out in the morning on the newspaper what really happened.
Visually, we have an action, horror theme. The grid sits on a dark, narrow alleyway in a Victorian city. We see dimly lit buildings with windows with lighting subdued, emphasizing the shadows and creating a slightly eerie atmosphere. Soundtrack-wise, we hear dramatic orchestral music incorporating instruments like strings, piano, and woodwinds that create a suspenseful and mysterious atmosphere.
10, J, Q, K, and A royals represent the low value symbols, while a newspaper, a pocket watch, a microscope, a potion brewer, and Dr. J offer the highest payouts. Here is the paytable:
A and K: 3, 4, or 5 = 0.75, 3.00, or 5.25
Q, J, and 10: 3, 4, or 5 = 0.75, 2.25, or 4.50
10: 3, 4, or 5 = 0.75, 1.50, or 3.00
Beaker and Test Tubes): 3, 4, or 5 = 2.25, 4.50, or 9.00
Microscope: 3, 4, or 5 = 2.25, 4.50, or 9.00
Pocket Watch: 3, 4, or 5 = 1.50, 3.75, or 6.00
Newspaper: 3, 4, or 5 = 1.50, 3.75, or 6.00
Potion of Madness features a Super High Paying symbol – Dr. J. This symbol can be transformed into a WILD symbol. Additionally, we are presented with a SCATTER symbol – Potion of Madness. The SCATTER symbol triggers all the features. The type of feature depends on the number of SCATTERS that land, or on this in the bonus features.
The Potion of Madness scatter symbol is the key to unlocking the various bonus features within the game. The number of these scatter symbols that appear on the reels dictates which specific feature will be activated, ranging from symbol transformations and respins to free spins.
1 SCATTER symbol triggers the TRANSFORMATION feature: all “Dr. J” symbols are transformed into WILDS
2 SCATTER symbols trigger the RE-SPIN feature: all “Dr. J” symbols are transformed into WILDS and a RE-SPIN is triggered
The RE-SPIN feature triggers a transformation of all “Dr. J” symbols into WILDs, which then become sticky for the duration of the respins. While only one WILD symbol can land per reel, any existing WILDs have a chance to expand vertically. Respins continue as long as these WILDs expand, new WILD symbols appear, or until there’s no remaining space on the reels for further expansion or new WILDs. These sticky WILDs remain in place until the RE-SPIN feature concludes.
Landing three or more SCATTER symbols initiates the FREE SPIN feature, which awards five free spins. During the free spins, the reel grid expands to a 5×6 layout. All “Dr. J” symbols are automatically transformed into WILDs. Furthermore, landing a WILD symbol during free spins triggers a RE-SPIN session, functioning similarly to a respin triggered by two SCATTER symbols in the base game. However, only one RE-SPIN session can be triggered per free spin, with a maximum of five separate RE-SPIN sessions throughout the entire free spins feature.
