Build My Brainrot

Build My Brainrot is a meme-fueled Roblox simulation where base building meets competitive chaos. You collect bizarre Brainrot characters, stack income, and expand a multi-floor base while rival players hunt the same prizes. Every purchase fuels growth, every mistake invites theft, and every round pushes smarter planning. Jump in, flex your collection, and outbuild everyone around you now!

GAMEPLAY OVERVIEW

Your journey in Build My Brainrot starts inside a personal base with limited cash and a shared central conveyor spawning Brainrots in real time. You just need to use the arrow keys or the virtual joystick to guide your character. You sprint to claim valuable characters before others react, then escort them safely home to generate income. Bases grow upward, forcing choices between defense upgrades or faster expansion. Meanwhile, rival players can invade, steal characters, and disrupt income streams if timing slips.

Base locks activate laser grids temporarily, forcing attackers to retreat or wait. Fusion stations allow combining duplicates into rarer income engines. Rebirth resets short-term gains but unlocks lasting multipliers, new floors, and higher capacity. Every session blends speed, awareness, and meme-fueled rivalry into nonstop tension.
