Merge Tower Defense codes not working? Check out the reasons
Can’t seem to get your Merge Tower Defense codes to work? Here are some of the common reasons why this can be happening:
Expired redeem code. Some codes simply won’t work if the reason is they are expired. We distinguish between the active and expired codes in different sections for readers to differentiate easily. Always use codes from the active section to get your rewards guaranteed.
Code is case sensitive. Merge Tower Defense codes need to be entered exactly as shown, capital letters and all. A small mismatch will stop the reward from coming through.
Do not commit typing mistakes. For the best results in redeeming your code without errors, we suggest simply copying and pasting the codes from this page. This will save you a lot of time and energy instead of manually typing each one at the risk of committing mistakes.
Redeem code already used. Most codes can only be claimed once per account. If you have already redeemed it earlier, using it again will not grant a second reward.
How to get more Merge Tower Defense codes?
In case you are trying to get more Merge Tower Defense codes, you’re not alone in this endeavour. Many players are searching for this query, and none have definitive answers. After all, codes do not come with a specified release timeline. They are randomly released by the developers.
You can bookmark this page to check back for new codes. While you wait, we suggest joining the official Merge Tower Defense Discord server and keeping an eye on the announcement channel, since that is usually where new codes appear first.

Is there an official Motorcycle Mayhem Discord server?
Yes, Merge Tower Defense does have an official Discord server run by the developers. Codes and updates are often shared there first, so it is worth joining if you want early access. It is also a good place to connect with other players and stay updated on future events.
