Common failure reasons
Expired codes show invalid messages even when typed correctly. Developers retire launch codes silently. Case sensitivity breaks codes like ducktime and DuckGo — copy from the codes page without retyping.
Already-redeemed codes fail on second attempts. One use per account is standard. Region-locked codes may work later when global activation opens.
Fix checklist
Restart the game after updating the app. Finish the tutorial through the main menu. Paste from clipboard instead of manual entry. Remove spaces. Try one code at a time to see specific error text.
If every code fails, verify you installed from the official store listing — mod APK clients sometimes use incompatible servers.
When to wait versus report
Newly announced social codes may activate hours later. Watch Discord via the community hub. Persistent failures on official clients after updates may need customer support through in-game help links.
