- Click the Codes button on the main menu.
- Paste one of the codes below exactly as shown (case-sensitive, mixed case on most).

Codes expire without notice, so redeem the top of the list first. If a code returns invalid, it has either been used the maximum number of times or a new update has rotated it out. Rejoin the server once, then try the next code.
When Do New Merge Tower Defense Codes Drop?
The Merge Tower Defense dev drops codes at version updates (UPD6.0 for 1,000 Diamonds), themed tower drops (VOIDAWAKENING, Genesis for 1,000 Diamonds; Biotrix, HellGuard, Aegis, Corruptor for 500 Diamonds each), visit or member milestones (TY20M and MTD1K for 1,000 Diamonds, DiscordMembers for 1,000 Diamonds), and starter or event drops (Welcome and DAMAGERAID and SAFEGUARDPROTOCOL for 500 Diamonds).
🎮 About Merge Tower Defense
Merge Tower Defense is a Roblox tower defense where you merge duplicate tower units into stronger tiers, hold off waves across themed maps, and stack Diamonds to roll for rare tower unlocks.
VOIDAWAKENING, UPD6.0, Genesis, MTD1K, and TY20M each drop 1,000 Diamonds, and DAMAGERAID, SAFEGUARDPROTOCOL, Biotrix, HellGuard, Aegis, Corruptor, Welcome, and DiscordMembers round out the rest at 500 Diamonds each.
Diamonds are the rare-tower currency, so stacking all 13 codes on a fresh account gives a fresh player a solid bankroll toward rolling for top-tier merge results.
Two older codes (dude, arcane) have rotated to the expired list from earlier themed content drops.
All codes in this list are case-sensitive and released by the developers of the game. Codes can expire without warning; if one shows invalid, it was already rotated out.
