Alchymedes slot

Alchymedes was one of Yggdrasil’s early flagship titles, launched in 2017. It runs on a level-based system where a spreading wild pattern grows across the grid, and the player chooses at the end of each level whether to widen the wild coverage or push the multiplier up instead. The RTP is a clean, unhedged 96.10% across sources, with no operator-side splits here. Medium volatility, on a 5-reel, 4-row grid that pays both directions.

The grid is 5 reels, 4 rows, with 30 fixed paylines that pay both left-to-right and right-to-left. This double-direction scoring roughly doubles how often a given symbol run counts as a win, without adding a single extra reel. Bet range on this site’s build runs from $0.01 up to $2 a spin, though the exact minimum and maximum shift depending on which operator’s version you load. Controls are standard, with adjustable coin size, autoplay, and an in-game paytable built into the interface. It’s built on HTML5, so there’s nothing to install on desktop or mobile.

Alchymedes runs on a level system built around a spreading wild pattern that fills in across the grid over several spins, replacing the traditional free-spins round entirely. When a level completes, the player picks one of two paths: add more wild coverage to the next pattern, or grow the level’s running multiplier instead.

Alchymedes runs a clean, unhedged RTP build on this site, with no operator-side split to call out.

Alchymedes runs on HTML5. It loads directly in a mobile browser on iOS or Android, no app or plugin required. The 5×4 grid scales down cleanly to a phone screen without the paytable becoming unreadable.

A free demo is available through Yggdrasil’s own game launcher, no signup needed. It’s the quickest way to see a few levels of the Spreading Wild Pattern play out and to get a feel for how the level-choice mechanic actually affects a session before spending anything real.

The casino list above isn’t filtered by game or software provider, so use the lobby search bar to confirm a given operator actually carries Alchymedes before signing up. The welcome offer, its wagering requirement, and the exact RTP build all vary by casino, so it’s worth checking the game’s info panel after you load it, before committing real money.

If the alchemy-lab theme is what drew you in, the broader magic-themed slot library and the Yggdrasil Gaming catalog both have more in the same vein.

Alchymedes focuses on a single, core mechanic. The level-by-level Spreading Wild Pattern gives the player direct control over how the mechanic grows spin after spin. Load Alchymedes if you want a say in how wild coverage and multiplier build across a session, on a clean, unhedged RTP build with a 10,000x ceiling.
