What Are Brainrot Tower Defense Codes?

Brainrot Tower Defense codes are special promotional gifts from the developers that give you free in-game rewards like Gems, Fish, Presents, and other valuable items. These codes are released to celebrate game milestones, major updates, holidays, and special events.

Why Gems Matter in Brainrot Tower Defense?

Gems are the premium currency that powers your entire strategy in this meme-powered tower defense experience. Here’s why they’re absolutely crucial:

Summon Powerful Brainrots: Each summon costs 500-2,000 gems depending on the banner

Skip the Grind: Why spend hours farming when codes give you thousands of gems instantly?
Experiment with Strategies: More gems = more summons = more opportunities to test different unit combinations
