The Biggest Number

About The Biggest Number: Fast-Paced 3D Number Runner

The Biggest Number is a fast-paced 3D number runner and casual math game where every choice can make you stronger—or end your run. The goal is simple and satisfying: collect numbers, grow as large as possible, and smash through as many walls as you are able to at the finish line. Red circular objects with protruding spikes sit within recessed pits along the track. A rainbow-colored arch stands above a checkered finish line at the end of the track. Green rectangular pads with three upward-pointing chevrons are distributed along the path.

How to Play The Biggest Number: Collect, Grow, and Smash

Reach the finish with the biggest number possible and smash through as many walls as you are able to. Collect numbers equal to or smaller than yours to grow. Avoid larger red numbers—they will stop your run. Along the way, math gates let you choose your route: addition and multiplication boost your value, while subtraction and division reduce it, so picking the right path matters. Spinning saws, gaps, and traps also stand between you and the finish line.
