Expired codes
None— There are currently no known expired Build a Brainrot Farm codes.
Why codes might not work
- The code has expired and is no longer active, so the game refuses the redemption.
- There is a typo, missing character, or extra space; codes in Build a Brainrot Farm are case-sensitive and must match exactly.
- You already redeemed the code on your Roblox account, and most codes can only be used once per account.
- The game server you are on has not updated yet; rejoining the experience or restarting Roblox can help.
