Flash Digits: Memory Challenge

How fast can your brain capture a number?

Flash Digits shows you a 4-digit number for a split second — then hides it. Type what you saw. Get it right, and the next flash gets faster. Get it wrong, and it's game over.

It starts easy at 0.9 seconds. But every correct answer shaves 60 milliseconds off your time. Before you know it, numbers are flashing at inhuman speeds — and only the sharpest minds survive.

HOW IT WORKS
A 4-digit number appears on screen. It vanishes almost instantly. You type the number from memory. Correct answers speed up the next flash. One wrong answer ends the game.
