After going back to the game again, I think it has to do with your ability to remember a number of things and the pattern in which you find them. I found that I cannot get more than 7 correct, and when presented with 8 numbers, cannot get the order correct. However, my score has improved. So each time you play, your brain becomes more adept at the process. It now says my brain is 20 - am I losing ground??? I don't ever want to be a teenager again! :lol: :lol:
