Number Rush

Forty-five seconds. Faster numbers. Slightly less time to overthink.

A shorter burst of mental arithmetic for when one minute feels like a whole meeting.

The difficulty climbs every few correct answers, so the early questions warm you up before the numbers get rude.

Can I pause it?: No. The point is the sprint.
Does it get harder?: Yes. The generated problems step up as you answer correctly.
Is speed more important than accuracy?: The game records both. A fast wrong answer is still wrong.
Can I retry?: Yes. Each run starts fresh.

This is a timed arithmetic game, not a validated measure of mathematical ability. It describes performance in this run only.
