Lucky Block Rush Brainrot Tier List

The Brainrot tier list ranks collectibles by rarity and cash-per-second income. Brainrots are the primary income source in Lucky Block Rush, making this the most important tier list for progression planning.

S-Tier: Secret Brainrots

Secret Brainrots generate 100K+ cash per second and represent the pinnacle of collection. Obtained from high-tier Lucky Blocks against endgame NPCs with luck boosts active. Never sell or replace unless upgrading to a higher-level Secret. Essential for leaderboard income.

A-Tier: Mythic Brainrots

Mythic Brainrots earn 10K-100K/s and serve as endgame staples for most players. Obtainable from mid-late enemy tiers with Luck Potions. Codes like Release and Magia sometimes grant Mythic-tier units during promotions.

B-Tier: Legendary Brainrots

Legendary units produce 1K-10K/s — reliable mid-game income. Common drops from mid-tier enemies. Upgrade levels aggressively before replacing with higher rarity.

C-Tier: Rare Brainrots

Rare Brainrots generate 100-1K/s. Early game workhorses obtained from starter and early enemy tiers. Keep until Legendary replacements are available.

D-Tier: Common Brainrots

Common units earn 1-50/s. Tutorial and first-block drops. Replace as soon as Rare or better units are available. See Brainrots item page and Farming Guide.
