Lucky Block Rush Brainrots

Last updated: 2026-06-20

Brainrots are the heart of Lucky Block Rush's economy. These collectible units generate cash per second when placed at your base, including offline earnings. Every progression decision should consider its impact on Brainrot income.

Brainrot Mechanics

Obtain Brainrots from Lucky Blocks, codes, and events. Place them on base slots to activate income generation. Upgrade individual Brainrot levels with cash to increase per-second output. Higher rarity tiers produce exponentially more income.

Rarity Tiers and Income

Common (1-50/s), Rare (100-1K/s), Legendary (1K-10K/s), Mythic (10K-100K/s), Secret (100K+/s). See the Brainrot Tier List for detailed rankings.

Placement and Upgrades

Fill all base slots before upgrading individual Brainrots beyond level 3. Empty slots waste potential income. Upgrade highest-rarity Brainrots first for maximum return per cash spent.

Code Brainrots

Release grants Frulli Frula Brainrot. Magia grants a Magia Brainrot. Both are valuable starter units — place immediately after redemption. See Active Codes.

Farming More Brainrots

Combat NPCs, open Lucky Blocks with Luck Potions active, and progress through enemy tiers for better drop rates. Read the Brainrot Farming Guide for advanced strategies.
