Forbidden Alchemy

Forbidden Alchemy by PG Soft launched in January 2026 with a mechanic that keeps building even after the free spins start: persistent multipliers. On a 5x4 grid with 20 paylines, Wild Transformation randomly converts high-value symbols into Wilds while simultaneously adding to a multiplier pool. In free spins that pool carries over from spin to spin, compounding toward an 8,000x maximum. RTP is 96.76%, volatility is high. Available on desktop and mobile at Wild.io via crypto.

What is Forbidden Alchemy?

Forbidden Alchemy is a 5x4 video slot from PG Soft with a 96.76% RTP, high volatility, 20 paylines, and a maximum win of 8,000x your bet. The standout mechanic is a persistent multiplier during free spins: each Wild Transformation event adds to the multiplier pool, and that combined value applies to all wins for the rest of the feature rather than resetting between spins.

PG Soft built the game around a dark alchemical laboratory setting with an extra transformation reel above the main grid. That reel selects high-value symbols at random and converts matching positions on the playing grid into Wilds, with each transformation incrementing the multiplier. In free spins the multiplier persists, meaning late-feature wins can arrive with a multiplier built across multiple prior spins.

How To Play Forbidden Alchemy Slot - Step By Step

Head to Wild.io and create a free account to start playing Forbidden Alchemy.

1. Set your bet on the 5x4 grid with 20 paylines paying left to right. The extra transformation reel sits above the grid and is visible throughout.
2. Watch for the Wild Transformation to fire at random. A high-value symbol type is selected from the transformation reel and its matching positions on the grid convert to Wilds. Each conversion adds to the multiplier counter.
3. Land three, four, or five Scatter symbols to trigger free spins: three award 12 spins, four give 15, and five give 20.
4. During free spins the multiplier pool accumulated in the base game does NOT reset. Each new Wild Transformation continues adding to it, and the combined multiplier applies to every win.
5. Landing two or more Scatter symbols during free spins adds three extra spins to the remaining count.

You can also deposit using various supported payment methods.

Forbidden Alchemy Slot Theme & Graphics

Forbidden Alchemy sets its reels inside a Gothic alchemist's workshop, shelves of glowing reagents, bubbling flasks, and arcane manuscripts line the background. The symbol art uses alchemy-specific iconography: coral organisms, mandrake roots, a claw, and a skull for the premium tier, with standard Royal card ranks for the low pays. The color palette runs deep purples, greens, and amber, consistent with the laboratory setting.

The transformation reel above the grid is an unusual visual element that PG Soft uses to signal the Wild Transformation as an active, observable process. Each transformation fires with a dedicated animation showing the selected symbol type converting across the reels. PG Soft adapted the layout for mobile portrait mode, keeping the extra reel visible above the main grid without cramping the playing area.

Forbidden Alchemy Slot Symbols & Paytables

Eight paying symbols split into two clear tiers: four standard card-rank Royals at the low end and four alchemical reagents at the premium end. Any of the regular paying symbols can be targeted by the Wild Transformation mechanic.

Low Value Symbols

Standard card ranks, A, K, Q, J, and 10, form the low-pay tier, paying up to 4x your bet for five matching symbols. These appear with the highest frequency and are the most common symbol type selected by the Wild Transformation when the game converts them to Wilds, which can clear low-pay clusters from the grid while adding to the multiplier pool.

High Value Symbols

Four alchemical materials form the high-pay tier. Coral pays up to 8x for five on a line, Mandrake root up to 12x, the Claw up to 16x, and the Skull up to 20x. When the Wild Transformation selects one of these and converts matching grid positions to Wilds, the resulting Wild coverage combines with the multiplier addition for compounding effect. Landing the Skull-converted Wilds across a payline with a built-up multiplier is where Forbidden Alchemy's biggest wins originate.

Special Symbols

The Wild symbol substitutes for all regular paying symbols. Wild Transformations add to the multiplier pool with each conversion event, and during free spins the pool persists across spins rather than resetting. The Scatter symbol triggers the free spins feature when three or more land anywhere on the 5x4 grid, awarding 12, 15, or 20 spins depending on how many Scatters land.

Forbidden Alchemy Bonus Feature & Special Features

Wild Transformation with Multiplier

The Wild Transformation in Forbidden Alchemy fires randomly during any spin. An extra transformation reel positioned above the main 5x4 grid selects one of the high-value symbol types. All matching positions of that symbol type on the playing grid are then converted into Wild symbols. Each individual conversion adds to a multiplier pool displayed above the reels. In the base game this multiplier applies to the current win and then resets. In free spins the multiplier persists across the entire feature, meaning each new transformation event during the bonus adds to a growing total that applies to all wins from that point on. A late-feature transformation converting several grid positions can arrive on top of a multiplier built across eight or ten previous spins.

Free Spins with Persistent Multiplier

Free spins in Forbidden Alchemy trigger when three, four, or five Scatter symbols land anywhere on the 5x4 grid, awarding 12, 15, or 20 spins. The defining rule of the bonus is multiplier persistence: unlike in the base game where each transformation resets the pool, the multiplier accumulated during free spins carries forward from spin to spin throughout the feature. Each Wild Transformation that fires during the bonus adds more to this running total. A session where Wild Transformations fire several times in the first half of the feature leaves the remaining spins playing out with a built-up multiplier attached to every win. Landing two or more Scatters during the active bonus adds three free spins, extending the opportunity for further multiplier growth.
