How to redeem codes

To redeem codes in Merge Tower Defense, open the game's main menu, find the codes input field, type your code exactly as shown, and submit it. Codes are case-sensitive and single-use per account.

All code rewards are Diamonds - the premium currency used to purchase high-tier towers and upgrades. Most codes give 500 Diamonds each, while major update codes give 1,000 Diamonds - the UPD6.0 code awarded 1,000 Diamonds when Update 6.0 launched. With 7 active codes currently available, a new player can claim 4,000 to 5,000 free Diamonds just from redemptions, providing a meaningful head start for early premium tower access. Merge Empire releases new codes through their Discord server and at Merge Tower Defense update milestones - update codes follow a naming pattern (UPD6.0, and likely UPD7.0 in future). The Fandom wiki also tracks codes. Codes do expire - one has expired in the game's history - so redeem newly announced codes quickly.
