Important note on merch codes: The long codes you see online, such as “Huge Cat codes,” are usually single-use. They come inside official Pet Simulator toys sold in stores. If you own one of these toys, scratch off the label and enter the code in the game. Codes that someone else has already used will not work.
How to earn free Diamonds and rewards without codes
If you don’t want to wait for new codes, these methods will help you fill your inventory:
- Rank rewards: Complete the Rank quests in the quest bar on the right side of the screen. Each time you rank up, hit the “Redeem” button to collect thousands of Diamonds.
- Free gifts: Keep an eye on the gift boxes at the top of the screen. Every 10 minutes you spend in the game earns you free potions, books and Diamonds.
- Group chest: Join the “BIG Games Pets” group on Roblox, then claim your daily reward from the large chest in the game’s Spawn area.Social rewards: Use the board in the Spawn area to verify that you follow the developers on Twitter and YouTube, and you’ll get a permanent speed boost.
