How to Redeem Subterra Codes ?
Redeeming codes in Subterra is easy! Just follow these simple steps:

- Find the Codes NPC – Look for Chrysos (the Codes NPC) on the right side of your spawn point
- Enter the Code – Type or paste your working code into the text box

???? Pro Tip: If a brand new code isn’t working, try closing and reopening the game to join a fresh server. Sometimes new codes take a few minutes to activate across all servers!
Why Are My Subterra Codes Not Working?
If you’re having trouble redeeming Subterra codes, here are the most common reasons and solutions:
Typos and Case Sensitivity
Even a small mistake can make a code invalid. Double-check your spelling or copy and paste the code directly from this guide to avoid errors.
Code Expiration
Subterra codes have a limited lifespan and can expire without warning. That’s why I always recommend redeeming codes as soon as you find them!
Server Issues
Sometimes new codes don’t work immediately on all servers. Try rejoining the game or switching to a different server if you encounter problems.
Already Redeemed
Most codes can only be used once per account. If you’ve already redeemed a code, you won’t be able to use it again.

While Polyworks Studio hasn’t announced an official schedule, I’ve noticed these patterns based on my research:
