Catch a Brainrot Rarity Tiers - Value, Catch Rate and Zone Odds
verified · updated 2026-07-13 · Catch a Brainrot
Catch a Brainrot runs 6 rarity tiers. Rarity sets a brainrot's value multiplier, its catch rate, and how often that tier turns up in a given zone.
The six tiers
Each tier's value multiplier, catch rate and per-zone appearance chance:
- Common (#CECECE) - 1.0x value multiplier, 100% catch rate, 100% zone appearance chance.
- Uncommon (#99FFA5) - 1.6x value multiplier, 90% catch rate, 18.33% zone appearance chance.
- Rare (#2EC7FF) - 3.3x value multiplier, 84% catch rate, 3.36% zone appearance chance.
- Epic (#B639FF) - 5.3x value multiplier, 70% catch rate, 0.315% zone appearance chance.
- Insane (#FF3333) - 10x value multiplier, 36% catch rate (very hard), 0.012% zone appearance chance.
- Exclusive (#FFBF00) - event-only; does not spawn in any zone.
Practical takeaway
What the numbers mean for actual play:
- Insane sits at roughly 1 in 8,000 spawns in a zone that carries it - expect a long grind for one.
- Insane and Epic together make up the hoarding-value tier, since they carry the highest sell multipliers of any spawnable rarity.
- Exclusive brainrots skip zone spawning entirely - they come from limited events, not from exploring.
