Slime Lab
An axolotl scientist's lab where a shattered Catalyst Vial fuses matching goo into the next creature up — and every fusion fills a tube that vents giant MEGA GOO wilds.

Every mode, with its cost and RTP
| Mode | Cost | RTP | What it does |
|---|---|---|---|
| Standard Play | 1× | 96.50% | Ways, tumbles and Catalyst Vial fusions; the Specimen Tube marks at 3, 6 and 9 fusions |
| Cold Fusion | 1× | 96.50% | The same 1× stake on its own reels: Vials reach far more boards, the tube marks at 2, 4 and 6 with one MEGA GOO wild per mark, and tumbles stop after 4 steps. Many small returns |
| Vial Boost | 1.5× | 96.50% | More Catalyst Vials, so more fusions, for that spin only |
| Pure Culture | 50× | 96.50% | One spin on special reels with no glassware: every fusion makes a bigger goo creature, each tube mark floods 2 MEGA GOO wilds, and tumbles stop after 4 steps. Not a Free Spins entry |
| Meltdown | 100× | 96.50% | Straight into Free Spins on the steady profile: frequent Vials, and every fusion climbs one rung |
| Overreaction | 100× | 96.50% | Straight into Free Spins on the spiky profile: rarer Vials, but every fusion climbs two rungs |
Availability: live on Stake as an Only on Stake title. Engine fixes a game's route at launch, so other casinos can't carry this one. It's here to show what we build.
