How fast can you count? 60 seconds. Answer math questions, build streaks for bonus time, and fight for #1 on the weekly leaderboard.
How fast can you do math?
NumbeRush puts your arithmetic to the ultimate speed test. A random equation appears — you have 60 seconds 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.
3 FREE PLAYS EVERY DAY
NumbeRush gives you 3 plays per day at no cost. Run out? Come back tomorrow for a full refresh. No subscription required.

THE MORE YOU PLAY, THE FASTER YOU GET

Download free. Play instantly. Beat your best.
