Welcome to the ultimate crossover event where the laws of mathematics meet the chaos of object shows! In BFDI x Numberblocks: Ultimate Sandbox Chaos, the borders between Goiky and Numberland have vanished, leaving you with a massive, open-world playground to explore, create, and disrupt.
There are no contests to lose and no lessons to learn—unless you want to make them! This is a pure physics-based sandbox where your imagination is the host.
