Forbidden Alchemy Slot by PG Soft

Four ingredient symbols sit above the reels - Coral, Mandrake, Claw, Skull - each paired with its own multiplier tracker starting at zero. On any spin the Wild Transformation Feature fires at random, selecting one or more of those four ingredients. Every instance of the selected symbol on the grid converts to Wild, and each conversion ticks its tracker up by one. Wins that spin get multiplied by the combined total of all four trackers added together. In base game the trackers reset after every spin, so the conversion count on a single spin is all that matters. Two Skull symbols transforming and one Coral means a x3 multiplier applied across all 20 paylines before the round clears.

Free spins flip that reset rule. Land three scatters for 12 spins, four for 15, five for 20 - and every tracker increase from Wild Transformation persists through the entire bonus. Spin one might build the Mandrake counter to x2. Spin four adds x1 to Skull and x1 to Coral. By spin ten the combined multiplier sitting across those four trackers could be x8, x12, or higher, applied to every winning combination for the rest of the round. Two scatters during the bonus retrigger with 3 extra spins, giving the counters more room to climb. You can buy straight into free spins if building through base game feels slow.

The dark fantasy setting leans into muted earth tones and decay - cracked stone, dried herbs, animal remains arranged like alchemical reagents across a desolate backdrop. Low-pay card symbols are etched into what looks like weathered parchment, while the four premium ingredients carry enough visual weight to read instantly on the grid. If the combined multiplier and payline hits push total wins to 8,000x in a single spin or bonus round, the game cuts the feature short and pays the cap.
