How Base Skins Work in Steal a Brainrot
Your base serves as your primary storage facility where all acquired brainrots generate passive income. Starting with a basic single-floor structure, players can expand up to 4 floors by progressing through Rebirth levels. Each floor increases storage capacity: Floor 1 (10 slots, Rebirth 0-1), Floor 2 (11-18 slots, Rebirth 2-9), Floor 3 (19-25 slots, Rebirth 10-17), and Floor 4 (26-31 slots, Rebirth 18+).

Base skins not only customize your base’s appearance but also provide passive income bonuses that accelerate your progression. The lock timer starts at 60 seconds, with each Rebirth adding 10 seconds, plus an additional 10 seconds for VIP pass holders.
