Note: Event codes can move between working and expired status when seasonal content ends or reruns. If a code marked as working returns an error, it has likely been retired on your current server.
How to redeem Catch a Monster codes
Step 1: Start Roblox and launch the experience page for Catch a Monster. Wait until your character fully loads into the world.
Step 2: Look at the top-right corner of the screen and click the gift or gift-basket icon labeled for codes. This opens the code redemption window.
Step 3: Click inside the text box, then carefully type or paste one working code from the list above. Use the exact spelling and capitalization shown.
Step 4: Press the Redeem button. If the code is valid on your server, a confirmation message appears and the items (potions, eggs, stones, currency, or keys) are added to your inventory immediately.
How to tell if a Catch a Monster code worked
After pressing Redeem, a successful code triggers a short on-screen notification confirming the reward. You should then see one or more of these changes:
- New XP or Coin Potions appear in your potion or consumables tab.
- Event items such as Candy Canes, Christmas Keys, New Year Fireworks, or Tower Gems increase in your currency or event counters.
- New Eggs, Boss Eggs, or special stones are added to the relevant inventory slots.
If no confirmation appears and your inventory does not change, the code was either entered incorrectly, already used on your account, or is no longer active on your current server.
Why Catch a Monster codes might not work
When a code fails, the usual causes are straightforward:
- Typing mistakes – Codes are case-sensitive in some batches. Extra spaces or wrong characters will invalidate them. Copying and pasting directly into the text box avoids this.
- Expired campaign – Seasonal codes linked to Christmas, New Year, or specific updates can be turned off without warning once an event ends.
- Old server session – If you have been online for a long time through multiple updates, the client can lag behind the current code list. Leaving to the main menu and rejoining Catch a Monster refreshes your session.
- Already redeemed – Most codes are limited to one redemption per account. Trying to reuse them usually shows an error message.
If a code that is widely listed as active repeatedly fails after checking spelling and rejoining, treat it as expired for your region or server.
