The world of Slime RNG is split into 7 distinct biomes, each unlocking new enemies, exclusive slime drops and a Crafting Machine. Tap any biome to see its lore, unlock requirements and exclusive slime list.
- Total Biomes
- 7
- Endgame Zone
- Void Realm
- Starter
- Beginner Pond
The Slime RNG biomes form the core progression chain — clear one to unlock the next, and gain access to its exclusive slime pool plus a dedicated Crafting Machine. Drop modifiers, enemy difficulty and Goop yields all scale with biome depth, so picking the right biome to farm is the single biggest decision after your luck stack.

Slime RNG biomes · FAQ
The questions players ask most about biome unlocks, exclusive slimes and Crafting Machines.
How many biomes are in Slime RNG?
Slime RNG currently has 7 biomes — Beginner Pond is your starting zone and the Void Realm is the current endgame zone (unlocked at Rebirth 3). Each biome has its own enemies, exclusive slime drops and a dedicated Crafting Machine.
How do you unlock new biomes in Slime RNG?
Each biome unlocks when you clear the previous biome's main quest or boss fight. The unlock requirement is shown on every biome card above. Some endgame biomes (Void Realm) require a specific rebirth count instead — see the Rebirth Guide for the exact thresholds.
Which Slime RNG biome has the rarest slimes?
The Void Realm holds the rarest pool — it's the only biome where Void Slime (1 in 10,000,000) can roll. For more obtainable rares, the Lava Caverns and Frozen Tundra biomes both have a 2× Goop drop modifier baked in, making them the best farming biomes pre-endgame.
Are biome-exclusive slimes really biome-locked?
Yes — biome-exclusive slimes only enter the drop pool while you're rolling inside that specific biome. 5 slimes across the wiki are tagged as biome-locked. Open any biome page above to see the full exclusive list before you start rolling.
Do all biomes have a Crafting Machine?
Almost — every unlockable biome past Beginner Pond has its own Crafting Machine with biome-specific recipes. You can't transfer recipes between machines, so progressing through the biome chain unlocks new craftable slimes. See the Crafting page for every recipe grouped by biome.
