Flash Digits vs BrainBlitz

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.
