Alchymedes – Yggdrasil Slot Review

Alchymedes by Yggdrasil Gaming is one of the most innovative online slots released by the award-winning provider. First launched on 24 January 2017, the game introduced players to a unique gameplay system focused on expanding wild patterns, evolving levels, and strategic upgrades instead of relying purely on traditional free spins features.
Inspired by the legendary Greek mathematician, inventor, and scientist Archimedes, Alchymedes combines ancient science with magical alchemy to create a distinctive slot experience that still feels fresh years after release. The game was one of the first Yggdrasil titles to heavily focus on progression-based gameplay mechanics, helping establish the provider as one of the most creative developers in the online casino industry.
While many modern slots rely heavily on bonus buys and extremely high volatility, Alchymedes takes a different approach. The game rewards players through a dynamic progression system that gradually improves wild patterns and multipliers as gameplay advances. Combined with more than 15,000 possible wild spread combinations, every session feels unpredictable and unique.
With a solid 96.1% RTP, medium volatility, excellent mobile compatibility, and a maximum potential win of up to €1,500,000, Alchymedes remains one of the standout classic releases from Yggdrasil Gaming.

Theme & Overall Design
Alchymedes takes players into a mysterious world of laboratories, ancient discoveries, magical potions, and scientific experiments. The game theme is loosely inspired by Archimedes himself, although Yggdrasil adds a fantasy-alchemy twist that makes the experience feel more adventurous than historical.
The game’s visual style mixes glowing laboratory equipment, colourful potion bottles, books of formulas, gemstones, and mystical symbols. The design immediately stands out compared to traditional fruit slots or generic fantasy games.
Despite being released back in 2017, the graphics still look impressive today. Yggdrasil was already known for producing high-quality animations and polished interfaces at the time, and Alchymedes showcases that attention to detail throughout the game.
The soundtrack complements the atmosphere perfectly, using mysterious orchestral tones mixed with magical sound effects whenever wild patterns spread across the reels. The animations during feature activations remain smooth and satisfying even on modern devices.
How Alchymedes Works
Alchymedes uses a unique 30+30 win-both-ways mechanic. Instead of traditional paylines only paying from left to right, the slot rewards combinations both ways:
- 30 paylines from left to right
- 30 paylines from right to left
This increases the number of potential winning combinations and keeps gameplay more active during regular spins.
The slot is played on a 5-reel, 4-row layout and revolves around the innovative Spreading Wild Pattern Feature. At the beginning of each level, a random wild pattern is selected from more than 15,000 possible combinations.
Whenever a wild symbol lands on the reels, it spreads according to the selected pattern. Some patterns may create small expansions, while others can dramatically cover large sections of the reels with wilds.
This mechanic creates enormous gameplay variety and ensures that every session feels slightly different from the last.
Spreading Wild Pattern Feature
The Spreading Wild Pattern Feature is the defining mechanic of Alchymedes and remains one of the most creative slot features developed by Yggdrasil Gaming.
At the beginning of every level, the game randomly chooses a spreading pattern from over 15,000 possibilities. This pattern stays active until the level is completed.
When a wild symbol lands:
- The wild expands according to the selected pattern
- Additional reel positions may become wild
- Winning combinations increase dramatically
- The feature can trigger massive chain reactions
Some wild patterns are relatively modest and controlled, while others can completely transform the reels into giant wild combinations capable of producing significant payouts.
This randomisation system is one of the main reasons why Alchymedes continues to have strong replay value years after its original release.
Level Progression System
Unlike many online slots that simply repeat the same gameplay loop, Alchymedes includes a progression mechanic that gradually evolves throughout the session.
As players complete levels, the game introduces stronger features and allows additional upgrades to both wild spreads and multipliers.
After completing a level, the player encounters the Alchemist’s Scale, where they must choose between two potion types:
- Green Potion – increases wild spread potential
- Red Potion – increases multiplier potential
This creates a light strategic element within the gameplay experience. Players can focus on larger reel coverage through stronger wild patterns or chase bigger payouts through improved multipliers.
The progression system gives Alchymedes a unique identity compared to more traditional online slots.
Multiplier Features
Multipliers play an important role in Alchymedes, especially during advanced levels.
As players continue upgrading the multiplier potion, the payout potential increases significantly. When combined with large wild spreads, multipliers can produce surprisingly strong payouts even from medium-sized bets.
Although the game’s volatility is officially rated as medium, the combination of wild expansions and upgraded multipliers can still create highly rewarding moments.
The maximum potential payout of the game reaches up to €1,500,000, giving Alchymedes very respectable winning potential for a slot released in 2017.
Symbols & Payouts
The slot features a mixture of themed and premium symbols designed around science and alchemy.
Lower-paying symbols include colourful gems and standard laboratory items, while premium symbols include:
- The Alchemist character
- Potion bottles
- Ancient books
- Magical equipment
The Wild symbol is naturally the most important symbol in the game due to its spreading capabilities.
While Alchymedes does not focus on massive single-symbol payouts like many modern high-volatility slots, the real excitement comes from combining expanding wilds with upgraded multipliers.
Volatility & RTP
Alchymedes features a 96.1% RTP, which remains highly competitive compared to many modern online slots.
The game is officially classified as medium volatility, meaning players can generally expect a balance between regular smaller wins and occasional larger payouts.
This makes Alchymedes suitable for a wider range of players compared to extremely volatile modern slots that may require larger bankrolls.
The win-both-ways mechanic also helps maintain active gameplay, with combinations forming more frequently than in standard fixed-payline slots.
Mobile Compatibility
Alchymedes was developed using HTML5 technology, allowing the game to run smoothly across desktop and mobile devices.
The slot is fully optimised for:
- Android smartphones
- iPhone & iPad
- Mobile browsers
- Desktop devices
- Tablets
The 16:9 game resolution ensures excellent scaling across different screen sizes without losing visual quality or gameplay functionality.
All core mechanics, including spreading wilds, multipliers, and progression features, remain fully available on mobile.
Why Players Still Enjoy Alchymedes
One of the biggest strengths of Alchymedes is its originality. Even today, many online slots continue using repetitive gameplay mechanics focused mainly on free spins and multipliers.
Alchymedes feels different because the gameplay evolves naturally through progression, wild patterns, and upgrade choices.
The randomised wild spread system creates huge gameplay variety, meaning players rarely experience the exact same feature setup twice.
Fans of feature-heavy slots and creative mechanics will likely appreciate the amount of detail and innovation packed into this Yggdrasil release.
