The Biggest Number

About The Biggest Number: Fast-Paced 3D Math 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. Sprint down colorful levels, collecting numbers equal to or smaller than yours to grow as large as possible, while dodging bigger red numbers, spinning saws, gaps, and traps. Math gates scattered across each route let you add and multiply your way to a massive score—or shrink it with subtraction and division if you pick the wrong path. Reach the finish and smash through as many walls as you are able to to set a new record.

How to Play The Biggest Number: Build and Smash

Grow Your Number

Collect numbers equal to or smaller than yours as you run. Larger red numbers will stop your run, so steer clear of them. The goal is to arrive at the finish line with the biggest number possible and break through as many walls as you are able to.

Choose the Best Gates

Addition and multiplication gates boost your value, while subtraction and division gates reduce it. Pick your route through each gate carefully to keep your number climbing.

Use Boosters

A shield protects you from danger along the track. A magnet pulls useful numbers toward you, making it easier to collect them without steering directly into each one.

Progression

Earn coins during runs and spend them on upgrades. Two upgrade paths are available: improving your starting number and improving your income, both of which help you progress faster across levels. Achievements and leaderboards track your best performances.
