About this game

How fast can you count?

NumbeRush puts your arithmetic to the ultimate speed test. A random equation appears — you have limited time to answer as many as you can. No multiple choice. No hints. Just you, a numpad, and pure mental speed.

How it works
The game throws addition, subtraction, multiplication, and division problems at you one after another. Type the answer and hit Enter. Get it right — the next one loads instantly. Miss — it slides away and a new one takes its place. The clock never stops. Your score is the number of correct answers when time runs out.

It sounds simple. It isn't.

Climb the leaderboard
Every week the leaderboard resets, giving everyone a fresh shot at the top spot. Enter your display name once, and every qualifying score you set is automatically submitted. See where you rank against players around the world.

Track your personal best
Your all-time high score is saved locally, so you always know the number you're chasing. A confetti burst fires whenever you break your record.
