Why codes might not work

  • The code has expired (most codes are time-limited and rotate frequently).
  • Typos or extra spaces — codes are case‑sensitive; copy and paste them exactly.
  • The code was already redeemed on your Roblox account.
  • Session or update issues — rejoin the experience or restart the Roblox app and try again.

Where to find more codes

New Subterra codes are typically shared on official channels: the developer’s Discord server, the Polyworks Studio Roblox group, and X (Twitter). Bookmark this page — we update code lists weekly.

Codes are case‑sensitive and available for a limited time. Avoid third‑party “code generators” or requests for your account details — they are unsafe and not required to claim in‑game rewards.
