Merge Tower Defense is a Roblox game where your mission is simple—survive endless waves of zombies. The twist? You’ll build your tower defense units by merging them and upgrading your fortress to handle harder and harder waves. As the challenge scales, so does the need for stronger units, which makes Diamonds incredibly valuable.

You can redeem Merge Tower Defense codes for free Diamonds, which are used to unlock premium upgrades and speed up your progress. If you’re aiming to build a reliable defense setup and fight a zombie horde, these codes will give you a much-needed boost early on. Below, you’ll find all the active and expired codes, how to redeem them, and tips for using your rewards effectively.

  • Merge often: three same turrets make one stronger sentry. The more merges, the more orbs you generate and you can convert them for cash.
  • AFK to grind: You can earn more Gems and Coins by staying logged in, even when idle.
