+1 Fat Per Step Codes

Open the Shop button on the left side of the screen. Inside the Exclusive Shop, scroll to the bottom to find the Enter Code text field. Type your code exactly as shown and press the green Submit button. Codes are case-sensitive and time-limited - they expire after a set period rather than staying active permanently.

Codes reward Fat Boosts (10-minute timed multipliers that accelerate fat gain from all sources), Title Rolls (gacha pulls for cosmetic titles that may carry fat multiplier bonuses), and Insane Title Rolls (higher-rarity guaranteed pulls). Fat Boosts are the most impactful reward for new players because early rebirth cycles are gated by reaching the floor-break size threshold, and a boost meaningfully shortens that grind. Title Rolls become more valuable at mid-game when multipliers start compounding.

New codes release at milestones such as visit and like counts, with updates, and around holiday periods. The primary source is the Fun Fat Studios Discord server announcements channel. Milestone codes are often embedded directly in the Roblox game description when the game hits visit targets. Since the game launched in January 2026, the code history is growing steadily with each new milestone.
