addicted to brain training games.

I have 4 brain training games on my mobile, and i make sure that i play them everyday. I love the ' brain age' part of the games, except whenever i get a low score on a game i enjoy, the next day i get a game im crap at and my brain age goes back up again lol. At least on the chart, in the profile bit, the lines only go up, not down lol. I may never be a member of mensa, but i am determent one day i will get a brain age of 20 in every game i play. I dont care how long it takes me.
