Lost Sword codes not working?

If you're having trouble claiming rewards, check these common issues related to Lost Sword codes:

• The code has expired. Many codes have a short shelf life, sometimes lasting only a day or two. If you’re seeing an error, the code may have already been deactivated. Check the status tag next to each code on our list.
• Codes are case-sensitive. This game enforces exact capitalization, so "FreeGems" won’t work if typed as "FREEGEMS". Copy the code directly from our list to avoid mistakes.
• Already redeemed. Codes are single-use. If you’ve redeemed a code before, even months ago, it’s permanently claimed on your account and can’t be used a second time.
• Complete the tutorial first. For Lost Sword, the code redemption feature is locked until you finish the tutorial. Play through the introductory stages, then revisit the code entry screen.
• Platform or region mismatch. With versions on iOS, Android, not every code works across all platforms. Double-check that the code applies to the version you’re playing.
• Check your in-game mail. If nothing happened after entering the code, don’t panic. Open your in-game mail or gift box, that’s where rewards are usually deposited.
