Be a Lucky Block Brainrot Database

Brainrots are the primary income source in Be a Lucky Block. When an NPC opens your Lucky Block, you transform into a random Brainrot. The rarity of the Brainrot depends on two factors: your Lucky Block's Luck stat and the distance of the NPC base from spawn. Successfully escaping the NPC base lets you keep the Brainrot and place it on your personal base.

Once placed on your base, Brainrots generate cash passively. This includes offline income, meaning your Brainrots continue earning cash even when you are not playing. Higher-rarity Brainrots generate significantly more cash per second. The difference between a Common Brainrot and a Cosmic Brainrot in terms of cash output is massive.

Brainrots are permanent. They survive Rebirth and cannot be lost once placed on your base. The only way to lose a Brainrot is to get caught by an NPC while carrying it back to your base before placing it. Once placed, it is yours forever.

Some Brainrots are exclusive to specific events or codes. Zeus Event Brainrots can only be obtained during Zeus Event cycles, Devil Event Brainrots only during Devil Event cycles, and Admin Brainrots only during Admin Abuse events. Code reward Brainrots are one-time claims per account.

Brainrot rarity directly correlates with cash generation. The game uses an 11-tier rarity system from Common to Cyber. Each tier represents a significant jump in passive cash output. When farming for Brainrots, always aim for the highest rarity your Luck stat can achieve.

Event Brainrots (Zeus, Devil, Admin) generally have higher cash bonuses than normal Brainrots of the same rarity tier. This makes event participation especially valuable for building a high-income base. I2perfectini Foxinini at +140% is the current cash champion.
