About this test

A number flashes on screen. Memorize it, then type it in once it disappears. You start at 3 digits and get one more digit each time you are right, and the number stays on screen a little longer as it grows (1 second plus 0.5 seconds per digit). Once you have it, tap "I've got it" to answer right away. You have two lives: miss once and you get a new number of the same length; miss twice and the game ends. Your score is the longest number you recalled.
