How to redeem codes

Click the settings cog (gear icon) in the lobby to open the settings menu. Find the codes input field, type your code, and submit. Codes can be redeemed from the lobby before entering a match. Codes are case-sensitive and each code is one-time use per account. There is no level requirement to redeem codes.

Codes reward Coins (for buying towers, skins, and emotes), XP (for leveling up your account to unlock harder maps and modes), Gems (premium currency for skins and crates), skins, and occasionally event-related items. Coins and XP are the most common rewards and help accelerate your progression toward unlocking advanced towers and harder game modes.

New codes release regularly with game updates, milestone celebrations (likes, visits, YouTube subscriber counts), holidays, and seasonal events. Primary sources are @BelowNatural on Twitter/X, the official TDS Discord server (400K+ members), and in-game news. Codes tied to updates tend to expire within weeks, while milestone codes can last longer.
