Current Active Codes
Status: No Active Public Codes (May 2026)
As of May 2026, there are no active public promo codes for Pet Simulator 99. BIG Games has shifted their reward strategy toward:
- Event-based rewards — earn free pets, gems, and boosts by participating in limited-time events
- Merchandise codes — one-time-use codes included with official BIG Games merchandise (plushies, collectibles) purchased from shop.biggames.io/codes
- Milestone rewards — automatic bonuses given to all players when the game reaches certain visit counts
Note: This situation is not uncommon for Roblox games. Many games transition from frequent public codes to event-driven rewards as they mature.
How to Redeem Codes
When codes are available, here is how to redeem them:
- Open Pet Simulator 99 in Roblox
- Click the Twitter/bird icon in the game lobby (usually on the left side of the screen)
- Enter the code exactly as shown in the text box (codes are case-sensitive)
- Press Redeem — rewards are delivered instantly to your inventory

Merchandise codes are the only working codes as of May 2026. They require purchasing physical products but offer significantly better rewards than traditional promo codes.
Event-Based Rewards

Current Event: Void RNG (Update 78)
- TITANIC Arcane Void Cat obtainable through RNG egg
- Multiple Huge pets with boosted rates
- Combo streaks for bonus rewards
