Pet Simulator 99 (PS99) has held its spot as one of Roblox’s biggest hits thanks to its addictive mix of collecting pets, trading, and strategic progression. But unlike most Roblox games that hand out freebie codes for milestones or updates, PS99 operates on a more exclusive system.

If you’re hoping to score free Gems, Huge pets, or exclusive rewards this September, it’s important to know how these codes actually work.

The Primary Source: Official Merchandise

The most reliable way to get valid PS99 codes is by purchasing official BIG Games merchandise. Each product usually includes a one-time-use DLC code tied to in-game rewards.

  • Plushies & Toys – Often come with exclusive pets, including highly coveted Huge pets.
  • Trading Card Packs – May include codes for Gems, boosts, or exclusive pets.

Because these codes are unique and one-time-use, any shared codes you see online are likely already redeemed. To avoid disappointment, the safest route is always buying directly from the official store or authorized sellers.

The Mystery of the “Super Secret Code”

For months, the community has been buzzing about a rumored “Super Secret Code” hidden in Preston’s Shop in Area 35. Despite countless theories and fake leaks, no official universal code has been released yet.

If such a code ever does go public, you can bet it will be announced through the official BIG Games channels—so keep your eyes peeled there instead of chasing unverified rumors.

How to Redeem Your Codes in PS99

Once you’ve got a valid code from merchandise, here’s how to use it:

  1. Launch Pet Simulator 99 on Roblox.
  2. Tap the pet icon at the bottom to open your inventory.
  3. Click the shopping cart icon to enter the Exclusive Shop.
  4. Scroll to the bottom until you see the “Redeem Codes” section.
  5. Press “Redeem!”, enter your code, and confirm to claim your rewards.

The Real Joy of the Hunt

Unlike other Roblox games where codes are handed out weekly, Pet Simulator 99 makes them feel special and rare. Whether you’re unboxing a plushie, opening card packs, or just keeping an eye on the official Discord, the hunt for rewards is part of what keeps the community buzzing.

Patience, persistence, and staying plugged into the official channels are the best ways to unlock the biggest rewards. And who knows? Maybe one day the mysterious “Super Secret Code” will finally make its debut. Until then, keep grinding, trading, and collecting—your next Huge pet might be just around the corner.
