The button is real
Codes were added on December 13, 2025. On June 13, 2026, during the Summer update, a community codes page says Sammy moved redemption onto its own button and took it out of the shop. Later October 2026 instructions say:
- Join the official experience and wait until you have a base.
- Open Codes on the left side of the screen.
- Type the code into the field labeled like Code Here.
- Press Submit.
- Read the message. Keep the capital letters, and do not add a space.
Older pages that say "open the shop and scroll to the bottom" describe the layout from before that June button.
A code is not always a free unit in your base
Two different rewards get mixed together in code lists:
- Some public codes spawn a Brainrot on the red carpet. You still have to buy it. One October 2026 write-up says La Vacca Saturno Saturnita from a code still costs $80M on the carpet. If you cannot pay, the code did not fail. You are short on cash.
- Some merch or card codes are described as adding a unit straight to the base, or putting a base skin in cosmetics. The confirmation line tells you which kind you redeemed.
Limited-stock codes in the expired list sold out. Entering them again will not restock them. Festive 67 and similar plush rewards used unique codes, not one public string.
BESTBRAINROTEVER is unresolved
A September 22, 2026 expired list includes BESTBRAINROTEVER for La Vacca Saturno Saturnita. October 4, 2026 code roundups call that same string active. Both cannot be published here as fact. It is not in the code table. If you try it, judge the game's reply, not a webpage date.
If Submit does nothing useful
Check capitals, check for a copied space, and check whether you already redeemed that string. A sold-out limited code and a code from a different Roblox game look the same when they fail. Random numeric codes posted for similarly named games are not this game's public list.
