How brainrots spawn, what luck and events do to the odds, and why Secret and Brainrot God tiers are so hard to roll.
How spawning works
Brainrots appear on a timer with a per-tier chance. Commons roll constantly; Mythic, Brainrot God, Secret, and Eternal tiers are rare rolls, often quoted as 1-in-thousands. Higher tiers earn vastly more, which is why the grind is worth it.
Luck and lobby level
Luck multipliers raise your odds of rolling a rarer brainrot. Higher lobby levels and certain upgrades stack with luck, so the same spawn timer yields better brainrots the deeper you are into a session.
Events and machines
Timed events and machines (Admin, Eternal, Lucky Rot) temporarily boost spawn quality or add limited brainrots to the pool — the best windows to chase a rare. See the Events guide for how to plan around them.

How do you increase your luck?
Stack luck multipliers from upgrades, gadgets, and events, and play in higher-level lobbies. Luck raises the chance of rolling rarer brainrots on each spawn.
What is the rarest brainrot?
Secret-tier brainrots are the rarest, with the lowest spawn chances, followed by Brainrot God and Eternal. They typically require high luck and patience, and many only appear during events or from specific machines.
