As of October 8, 2026, the Roblox listing for Mythical Tower Defense advertises the code Merchant_1. It does not state the reward. A third-party tracker listed 16 active codes on September 30, but those codes and rewards have not been verified in-game here, so treat that list as leads to try—not a guarantee they still work.
Latest officially advertised Mythical Tower Defense code
The official Roblox page for Mythical Tower Defense by _ TD Games _ currently displays “UPDATE!!! USE CODE: Merchant_1.” The listing reported an update on October 5, 2026, and was checked October 8, 2026. It does not give a reward amount for this code, so no specific number of Gems or Coins can be confirmed from the listing.
Make sure you are viewing the experience by _ TD Games _, Roblox experience ID 102304385522813. Roblox describes it as a strategy tower-defense game about defeating waves of monsters and collecting mythical units.
Other codes reported by a third-party tracker
Roblox Den reported 16 active codes and 0 expired codes when it checked its Mythical Tower Defense codes page on September 30, 2026 (UTC). Those are tracker-reported statuses, not confirmations from the game developer, and they were not independently verified in-game. The check predates October 8, so a listed code may no longer redeem.

How to redeem codes
The official listing captured here shows a code but does not explain the redemption steps. The available redemption instructions for the similarly named game Tower Defense: Mythic apply to a different Roblox experience by MuPower, not Mythical Tower Defense. Do not assume its settings-menu instructions work in this game. Use only a redemption option presented in Mythical Tower Defense itself, if available.
