Plant Brainrot Simulator has you growing an army of plants that automatically blast waves of brainrot enemies trying to overrun your garden. Codes are the fastest way to stack up crystals, boost potions, and rebirth-tied rewards without grinding through every wave first.
Working Plant Brainrot Simulator codes
These codes are confirmed to work right now. Redeem them soon since Rainbow Isle Studio retires older codes as new updates roll out.

The rebirth-linked codes (UPDATE8 and UPDATE9) only pay out once you’ve hit the rebirth count they require, so redeem them again after reaching that milestone if the reward didn’t land the first time.
How to redeem codes in Plant Brainrot Simulator
Code redemption happens entirely inside the game menu, so you don’t need to visit any outside website to claim a reward.
A successful redemption applies the reward to your account immediately, whether that’s crystals dropping into your balance or a boost timer starting in the corner of your screen. If nothing changes after hitting Claim, double-check the spelling of the code before trying again.
Where to find new codes
Rainbow Isle Studio typically drops fresh codes alongside major updates, often tied to rebirth milestones or new plant releases. The game’s description page updates when a new code goes live, and the official Plant Brainrot Simulator Discord server posts codes as soon as they’re active. Joining the Rainbow Isle Studio group on Roblox is another way to catch announcements early.
Note: Roblox Premium subscribers earn 25% more coins on top of any crystals or boosts a code grants, so stacking a working code with Premium status gets your garden upgraded faster.

Redeeming codes takes less than a minute and gives your plants a real head start against the next wave of brainrots, so it’s worth running through the working list before you jump into a defense run.
