Chump, Chimp or Champ

You have to memorize every digit that appear on the screen after you press GO, and click on them in order of value (from lowest to highest). When you get all digits correct you win.

It is known that a chimpanzee can memorize 5 different things in 0.7 sec. How many digits can you memorize?

You can change the number of digits from 2 to 20, and the time (15 = 1½ second). Have fun...
