How the game works
Brainrots walk along the conveyor in the middle of the map. Buy one and it walks to your base, where it earns cash every second. Better (rarer) brainrots cost more and earn much more, so the loop is simple: buy what you can afford, collect your cash, and upgrade to rarer brainrots.
Rarities and mutations
Brainrots come in rarity tiers, from Common and Rare up through Epic, Legendary and Mythic to the top tiers such as Brainrot God and Secret. Mutations like Gold, Diamond or Rainbow multiply a brainrot's income, so a mutated brainrot of a lower tier can earn more than a plain higher one. Watch the conveyor for mutated spawns, especially during events.
Protect your base
Other players will try to steal your best brainrots:
- Lock your base whenever you leave it — the lock lasts a short time and must be renewed.
- Keep your most valuable brainrots furthest from the entrance.
- Stay near your base when you've just bought something rare.
- Use items and gear from the shop that slow or stop thieves.
Stealing safely
Steal from bases whose lock has just run out, grab the brainrot and run straight home — getting hit makes you drop it. Bases on servers with fewer active players are easier targets. Don't spend so long stealing that your own base is left open.
Rebirths
Rebirthing resets your progress in exchange for permanent bonuses such as higher income and more base space. Rebirth when you meet the requirement and your income has slowed — the bonuses make the next run much faster.
