Steal a Brainrot has shipped 47+ updates since launch in early 2025. This hub gives you the chronological view: when each major mechanic landed, what brainrots came with it, and which updates shifted the meta most.

Update 9: Cash limit raised Player cash storage cap raised from $1M to $10M, enabling Mythic and God purchases.

Update 11-20 — Expansion (mid-2025)
Update 12: Update Log v2 Update tracking improvements; cosmetic refresh.
Update 13: Admin War Limited-time event with admin-tier brainrots. The first introduction of "event-locked" brainrots that don't return.

Update 21-30 — Mid-game maturity (late 2025)
Update 22: Frightrot Frightrot Halloween brainrot added — first defensive-passive brainrot with built-in stun on touch.
