Why Aren't My Merge Tower Defense Codes Working?

Merge Tower Defense codes can stop working at any time. Here are the most common reasons a code might fail and how to fix each one:

• The code has expired. Codes are often time-limited — some expire within 24 hours of release. If a code isn’t working, it may have already expired. We mark codes as expired as soon as we confirm them.
• Codes are case-sensitive. This game enforces exact capitalization — "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 Merge Tower Defense, 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, PC, Mac, 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. Rewards don’t always appear on screen right away. Check your in-game mailbox, gift center, or inbox after redeeming — items are often delivered there instead.
• Server sync delay. Roblox experiences sometimes take a few seconds to sync rewards with the server. If the code worked but nothing appeared, try rejoining or switching servers.
