The Sandbox is partnering with TOWER through a brand new Tower Defense Game Jam!

As a part of the TOWER Franchise, Crazy Defense Heroes is a Free-to-Play tower defense mobile game developed by Animoca Brands, with RPG elements and card collectibles. Since 2021, along with the Launch of TOWER Token, the team attempted to implement multiple blockchain features to traditional Free-to-Play mobile games, like NFTs, Play-and-Earn, and Governance.

Submitting Your Entry

You MUST also submit your game to the following form link:

WARNING! If you submit your entry to the Game Jam gallery but do not submit it to the form linked above (or vice versa), your entry will not be eligible!
Slow down — check everything! Take the time to submit a qualitative experience, rather than rushing and submitting a half-finished experience.
