How Mutations Work in Steal a Brainrot
Mutations appear randomly when a Brainrot spawns. The system uses a chance-based generator controlled by rarity weights.
Understanding mutation spawn mechanics helps players predict farming results and optimize time spent in-game.

Each spawn goes through a random mutation check. If successful, the game assigns one mutation from the full pool.

Exact percentages are not officially published. However, current data-based behavior shows:
| Type | Chance Level |
| Common | High |
| Rare | Medium |
| Legendary | Low |
| Mythic | Extremely Low |

Best Farming Methods
