How to redeem codes

To redeem codes in Geometry Defense, click the Codes button in the top left corner of the screen. Type or paste your code and press Redeem. Codes are not case-sensitive based on existing patterns, but entering them exactly as listed is safest.

Codes reward G-Coins - the primary currency used to buy towers, skins, and charms in the respective shops. Amounts range from 50 to 120+ G-Coins per code. Seasonal codes have also awarded SnowCoins during the Winter Event. Every G-Coin helps, especially early when buying the first few towers beyond the default Shape Gunner.

The developer posts active codes directly inside the Roblox game description with the next milestone threshold noted ("Next code at 25K Likes"), making it easy to know when to check back. New codes drop at likes milestones (5K, 10K, 15K, 20K pattern) and occasionally from YouTube partner codes like undead_yt. Follow DuoGames! on Roblox and monitor the game description around milestone announcements for the fastest updates.
