I guess this is an ok game. It is very educational. I really don't play too much of this game because it is a little boring. I like checking my brain age, even though it is never accurate.
Very easy to play. I loved the challenges that make me think harder and it actually helped improve my critical thinking! I even saw my aunt ( who's a math wiz ) stumble on a problem! This is very worth it and no waste in buying!
Educational and wakes up your brain. Great brain exercise for summer while school isn't there. It also says how your brain can decline by age 20 if it's not used. I have both strenghs and weaknesses in the game.
