Slot Summary

Twenty fixed paylines cross Forbidden Alchemy's five reels, where ordinary high-paying symbols can change into Wilds and multipliers without warning. PG Soft uses that transformation to connect the alchemy subject directly to play: ingredients become more valuable forms as an experiment resolves. The 96.76% RTP, high volatility, and 8,000x maximum win give those sudden conversions a substantial mathematical range.

How It Plays

Winning combinations use 20 fixed paylines across adjacent reels from left to right. Regular symbols handle line wins until a random transformation changes selected positions.

Wild symbols substitute for regular paying symbols, while transformed multipliers can increase the value of the affected result. The random activation makes each conversion independent of a bonus trigger.

Theme & Atmosphere

Magic and Mystery meet inside an alchemist's laboratory, where skulls, mandrake, minerals, and elixirs present the experiment as a forbidden practice.

The darker scientific treatment distinguishes the setting from conventional spellcasting. Transformation is the connecting idea, linking unstable ingredients with symbols that change function during a spin.

Magic Mystery

Features & Win Potential

The Random reward can activate the Wild Transformation on any spin. High-paying symbols then become Substitution Symbols and may receive additive Multiplier values.

Scatter Symbols provide the second feature route by opening Free Spins. Landing more Scatters changes the quantity awarded rather than altering the base payline structure.

Bonus & Free Spins

Three or more Scatters trigger Free Spins, with additional Scatters awarding a different number of spins. Wild transformations and multipliers remain central during the round.

How this works

Each simulated spin either misses or returns a win drawn from a log-normal distribution, with the hit rate and spread set by the slot's volatility tier (High). The model is calibrated so the average return equals this slot's published RTP (96.76%), with wins capped at its top multiplier (8,000×).

This is a simplified, parametric model of the game's math — not its real paytable. It exists to make the house edge visible over many sessions, so the numbers above are averages across thousands of runs, never a forecast of one.

This is math, not a prediction. Real sessions vary wildly, and no strategy changes a game's built-in house edge. Play for fun, set limits, and never bet more than you can afford to lose.
