Why isn’t my Merge Tower Defense code working?
The most common reason is a small typo or capitalization error since Roblox codes are case-sensitive. Try copying and pasting the code directly instead of typing it manually. It’s also possible the code has already expired, as most codes have a limited lifespan. If a code from our list isn’t working, it may have been deactivated by the developers.
How often do new Merge Tower Defense codes come out?
There’s no fixed schedule, but the developers typically drop fresh codes when the game hits a major update, crosses a player milestone, or runs a special event. Joining the official Discord server is the best way to catch new codes the moment they go live.
