How to redeem codes

To redeem codes in Ultimate Tower Defense, click the blue Twitter bird icon on the left side of the in-game lobby screen. Type your code exactly into the field and click Redeem. Codes are not reported to be case-sensitive, but entering them precisely as written is recommended.

Code rewards include Rolls (pull new units from the gacha pool), Gold (the main currency for placing and upgrading units in battle), Gems (secondary currency for premium pulls and shop items), Trait Rerolls (randomize a unit's Trait bonus), Perk Rerolls (randomize a unit's Perk bonus), Lost Chests (containers with rare units not in the standard gacha), and occasional 2x Gold boosts.

Trait and Perk Rerolls are among the most impactful rewards - getting the right combination on a strong unit can make a significant difference in battle performance. New codes release with Battle Pass season launches, major updates, and community milestones. The official Discord server (announcements channel) is the primary source. Codes expire quickly - often within days to weeks - so redeem them immediately after they appear. With over 220 expired codes across UTD's lifetime, the game has maintained one of the most active code programs among Roblox tower defense games.
