🎮 How To Redeem Codes in Fat Simulator
- Launch Fat Simulator on Roblox.
- Tap the Codes button in the side menu.
- Type the code exactly as shown (all uppercase, mostly).
- Tap Redeem to claim the Crystals + Fatness drop.
Codes expire without notice, so redeem the top of the list first. If a code returns invalid, it has either been used the maximum number of times or a new update has rotated it out. Rejoin the server once, then try the next code.
When Do New Fat Simulator Codes Drop?
The Fat Simulator dev drops codes at Fatness milestones (FATNESS150K, FAT80, FAT200, FAT20), themed-food milestones (BURGER130K, BURGER190K, COUCH110K, COUCH170K, CALORIES180, FOOD160), seasonal events (SUNSHINES1 for the Sun Sworn Pet, CANDY), and content drops.
🎮 About Fat Simulator
Fat Simulator is a Roblox eating-idle where you chomp food tiles to scale your Fatness stat and your Crystal currency, then rebirth to unlock stronger maps and pets.
Crystals are the premium currency used for pet hatches and upgrades, while Fatness is your progression stat, and the code drops mix flat Crystal + Fatness bundles with pet rewards like the Sun Sworn Pet.
All codes in this list are case-sensitive and released by the developers of the game. Codes can expire without warning; if one shows invalid, it was already rotated out.
