Mental Math Sprint
How many can you solve in 60 seconds?
One minute. Answer as many arithmetic problems as you can — add, subtract, multiply, divide. Type each answer on the keypad and hit =. The longer your correct streak, the harder the numbers get. Your score is the number you get right.

How long does this test take?
One minute of solving. You answer as many arithmetic problems as you can in 60 seconds; the score is how many you get right.
Does it get harder as I go?
Yes. Every few correct answers in a row bumps the difficulty: numbers get bigger and multiplication and division kick in. A wrong answer resets your streak but never costs you points already earned.
Is this an IQ test?
No. This is a speed-arithmetic game that measures mental calculation under time pressure — one narrow skill. It is not an intelligence test and says nothing about your IQ. If math anxiety or dyscalculia makes timed sums stressful, treat the score as a game, not a verdict.
How does the leaderboard work?
Your number of correct answers in 60 seconds is recorded on a leaderboard. The weekly board resets every Monday (UTC); the all-time board never resets. Impossible scores are auto-rejected.
