Forbidden Alchemy

Forbidden Alchemy Review

Forbidden Alchemy is the first online slot built by PG Soft for the new 2026 and one of the two titles scheduled for release in January. At first glance, it comes with solid maths, high volatility, and a core feature with massive potential. The base game relies on a rather standard payout mechanic and a transformation feature. The bonus round comes with upgraded persistent multipliers that deserve a closer look.

PG Soft is a mobile-first game developer established in 2015 and constantly lifting the quality of its gaming content. A comparison with older games, like Alchemy Gold, shows significant upgrades in the visual elements and special features. PG Soft does not hesitate to experiment with advanced payout mechanics and new variants of popular modifiers. The company steadily releases at least 2 new titles per month.

Forbidden Alchemy also comes in a portrait style designed to entice mainly fans of mobile gambling. The basic layout includes 5 reels and 3 rows, with 20 lines, paying from the leftmost reel to the right. The graphics are polished, and the theme is a nice combination of science, witchcraft, and pure madness dressed in a gothic manner. Players can use Autoplay and Turbo Spin to facilitate their play.

You can test both via the Forbidden Alchemy demo link placed above! The game is packed with a Wild Transformation Feature, which is active in both game stages. However, during the Free Spins, it becomes truly powerful keeping and upgrading the jar multipliers unlimitedly. If all that sounds promising to you, let’s go deeper and learn more!

Forbidden Alchemy Slot - Reels Screen

Forbidden Alchemy is packed with 4 high-valued and 4 low-valued symbols that create winning combinations when 3, 4, or 5 land on a payline. Skulls seem to be the most valuable, paying from 4x to 20x the bet. Claws follow with 2x to 10x, along with Mandrakes and Corals - 1x to 8x. The low-paying A, K, Q, and J award between 0.20x and 4x the stake.

Wild symbols play a vital role in the action and are the key to cashing out more substantial payouts. For now, I’ll only state that, as usual, the wilds substitutes for all the other symbols, except scatters. The betting range is wide and configurable, and at its widest form, it supplies multiple stake levels between €0.60 and €180 per spin. That opens plenty of opportunities to those players feeling comfortable with the high levels of volatility.

The Forbidden Alchemy RTP rate is at the highest side of the slice and boasts 96.76%. That is not the highest rate we have seen in a PG Soft online slot, but close enough. The game’s high variance might be confusing and even dangerous if you don’t play with a betting strategy. The Forbidden Alchemy max win is also solid - 8,000x the bet.

Forbidden Alchemy Features

Forbidden Alchemy is a feature-driven online slot, meaning that the core mechanic is at the center of everything meaningful. As I already mentioned, wild transformations can boost the round wins massively, which opens the max win target for firing at. Still, you can’t expect this to happen on every spin, so you need to be patient. Here is all you can expect in the game besides line payouts:

Wild Transformation Feature

Wild Transformation may kick in on any spin and activate 1 or more high-valued symbols. They will be displayed in the jars above the reels, and all instances of the activated symbols on the grid will be transformed into wilds. Moreover, each instance will add +1 to the respective multiplier. Multipliers are additive, and their sum will be applied to the total win of the spin.

Free Spins Feature

Free Spins is the bonus minigame of Forbidden Alchemy, and you will need 3 or more scatter symbols to trigger it. Scatters do not pay direct cash, but 3, 4, or 5 of them will award 12, 15, and 20 free spins, respectively. The Wild Transformation multipliers will not reset between rounds during the bonus. They are persistent and progressive, with no virtual caps.

Whenever a win is achieved during the Free Spins and Wild Transformation is active, the total win will be boosted by the sum of all multipliers above the reels. This makes the potential outcome of a single round monstrous. Skaters continue to contribute to the length of the minigame, and if you spot 2 of them, you’ll get 3 extra free spins.

Theme & Graphics

Forbidden Alchemy is a mobile slot that comes with a story about a lost, forgotten, and recently found alchemist manuscript. It tells about a desolate island where the ancient art of alchemy was once thriving, yet in secret. Masters were using forbidden ingredients, which we now see in the high-valued symbol positions in the slot’s paytable. The mystical craft was offering powerful elixirs as a final result, capable of “reshaping fate and bending the laws of nature”.

Forbidden Alchemy comes with premium-quality audio and visual elements, clearly showing the provider’s ambition to level up into a new class. In the second part of 2025, PG Soft changed its approach to online slots, making them more visually appealing. I can see the efforts at the beginning of the new year as well. The game offers the mystical atmosphere that fans of the theme have been expecting. It is fast-paced, dynamic, and a must-try for me!

Forbidden Alchemy Free Play

The wisest way to test the online slot is via the Forbidden Alchemy free play mode. A demo link is placed at the beginning of my review and will lead you to the game with no strings attached. Use the wide and detailed betting range to try different strategies. Get acquainted with the rules, payouts, and features, and get yourself ready to put some real money on the alchemist’s table!

Pros And Cons Of Forbidden Alchemy Slot

Our Verdict

Forbidden Alchemy is an online slot crafted fully in PG Soft’s style. It is packed with a single feature that makes a huge impact during the base game and free spins. There are no complex mechanics here, but fast-paced gameplay, stacked multipliers, wilds, and a potential for a massive win of up to 8,000x.

When I think of this particular theme, I remember the Sweet Alchemy slots by Play’N GO. Forbidden Alchemy comes with a more polished visual performance, simple mechanics, and a rather brilliant approach. I can also compare it with Magic Lab and Merlin's Alchemy. These magnificent games built by NetEnt and Bullshark Games offer memorable twists like Mystery symbols, huge multipliers, grid modifiers, and advanced Pay Anywhere mechanics.

A major weakness of Forbidden Alchemy could be the periods of drought in feature activation. Since Wild Transformation is crucial, if it fails to deliver, it can ruin the entire bonus round. And Free Spins is not the easiest minigame to get! You will need at least 100 spins to trigger it unless you get lucky, and there are no bonus buy or bonus bet shortcuts to use. At the end, Forbidden Alchemy is surely worth the try, but the dead weight can be a serious issue!
