Why Codes Might Not Work
Codes might fail if you enter them incorrectly since Geometry Defense codes are case sensitive. Double-check for exact spelling and capitalization. If the code is correct but still doesn’t work, it’s likely expired and no longer valid.
What Rewards You Normally Get?
Most Geometry Defense codes reward you with G-Coins, the game’s currency used to buy towers and skins. Some codes also give regular Coins, which are earned by defeating enemies. Here’s a quick look at what you can expect:
| Reward Type | Description |
|---|---|
| G-Coins | Main currency for buying new towers and cosmetic skins in the lobby. |
| Coins | Earned by defeating shapes, sometimes given by codes, used for upgrades during matches. |
| Skins | Cosmetic items bought with G-Coins to customize your towers. |
| Tower Slots | Unlockable with G-Coins after reaching level 25, allowing more towers in battle. |
Codes mostly provide G-Coins, letting you unlock new towers or skins faster than normal play would allow.
