Wildchemy is Relax Gaming’s 2019 alchemy lab cluster slot with cascading reels, portal-spawned wilds, and a flask that hoards scatters across drops.
Long before Money Train turned Relax Gaming into a household name, the studio was quietly tinkering with cluster mechanics inside a 5×5 lab. Wildchemy launched March 2019 as a Unibet exclusive, and you can feel that experimental DNA the moment the bearded scientist Wild starts pulling levers.
The grid sits inside a copper-pipe distillery. Beakers bubble, flasks hiss, and a starry window glows above shelves stuffed with potions and old tomes. Symbols are split into ten payers (five high-pay elixirs, five low-pay alchemy ingredients) plus a Wild and a flask Scatter. Cluster pays handle the math, so you're chasing groups of matching symbols rather than left-to-right lines.
Here's where the design gets clever. After every win, avalanche cascades clear the symbols and drop fresh ones, chaining potential combos. During cascades, portal animations occasionally tear open on random reels and spit out Extra Wilds, which fold into any cluster forming around them. Meanwhile, every Scatter that lands gets siphoned into a flask meter on the side. And this is the part that surprised me, the flask doesn't reset between drops within a single spin sequence. Four flask Scatters across all the cascades from one bet trigger Free Spins with juiced-up wild generation.
RTP sits at 96.02% with medium volatility, bets run from 0.10 to 100.00 EUR, and the max win caps at 500x. Is 500x small? Yeah, by 2026 standards it's tiny. But the cap is intentional. The math model leans on frequent modest hits and longer cascade chains rather than hunting for one screen-clearing payout. So if you came here expecting a 50,000x pursuit, you'll be disappointed. If you came for steady avalanche rhythm with a satisfying flask meter ticking up, that's exactly what this delivers.
The criticism worth flagging: there's no Bonus Buy and no Ante Bet, so triggering Free Spins is purely down to patience. Some players will find that refreshing, others will bounce after twenty dry spins. Sound design is light, art is detailed without being cluttered, and the scientist Wild has just enough character to feel like a mascot rather than a placeholder. A neat little time capsule from when Relax was still finding its voice.
