Alchymedes

Alchymedes: Yggdrasil's Level-Based Alchemy Adventure

Alchymedes puts players inside the laboratory of a legendary alchemist, where the central promise is turning ordinary symbols into gold through a level-based progression system rather than a standard free spins bonus. It's one of the more structurally distinctive slots in Yggdrasil's catalogue, built around player choice as much as luck.

The 5-reel, 3-row grid runs on a win-both-ways format with 30 paylines active in each direction, for 60 ways to land a win in total. Three or more matching symbols create a payout whether they land left to right or right to left, and completing a level requires filling every position on the grid with winning combinations. After each level clears, players get to choose their own path forward: bigger multipliers, or larger spreading wild patterns on what the game calls the Alchemist's scales. Multipliers climb throughout each level and pay out on the level-ending spin, with a bonus feature at the start of each new level offering one of six possible rewards.

Visually, it's classic high-end Yggdrasil work - bubbling potions, ancient tomes and glowing golden transformations, with animations built around those spreading wilds and rising multipliers that make each level feel like it's building toward something.

On the numbers, Alchymedes carries a 96.1% RTP and medium volatility, a combination that should suit players who want steady progression without excessive swings. Stakes run from 20p up to £100 per spin. There's no bonus buy option here, so the level-based system has to be worked through the base game, which keeps the pacing a little more traditional than modern feature-buy slots.

With multipliers capable of climbing up to 100x and over 15,000 possible spreading wild patterns feeding into the choice-based level system, Alchymedes offers a genuinely different rhythm to most alchemy-themed slots. The 5,000x max win sits at a healthy level for a medium-volatility game, rewarding sustained level progression rather than a single lucky spin.

For players who enjoy having some say in how a bonus round develops rather than leaving everything to chance, Alchymedes is well worth exploring. The medium volatility and 96.1% RTP make it approachable, and the free demo at johnessyslots is the easiest way to try the level-by-level choice system before deciding whether to chase that 5,000x ceiling with real stakes.
