Crate Types and What to Expect
Crates determine how long you’ll need to break them and what kind of Brainrot you’ll get. Here’s a rough progression path:
Crate Type | Description |
---|---|
Wooden Crate | Basic, quick to open, gives Common units |
Rusted Crate | Slightly harder, better chances for Uncommons |
Scrapper’s Crate | Offers better units like Tralo or Gramaram |
Techno Crate | Mid-tier, includes Rares and above |
Ember Crate | High-tier, can drop Epic or even Legendary |
Quantum Crate | Among the best, higher odds for Secret units |
Oblivion Crate | Very high cost, can drop powerful mutated units |
Server Crate | Spawns globally, rewards all players who help |
You can also skip crate breaking (for a cost), or use an auto-clicker to speed things up.
Rarities and Mutations
Each Brainrot has a rarity that determines its income rate:
- Common
- Uncommon

- Legendary
- Secret
Some units come in mutated forms like Void, Titanic, or Burning, which boost their earnings drastically. For example:
