Good game to play once in a while, alone or with/against friends. Just good mental practice and fun!
Once you get to know the different types of skills you need to have during the game you can start to get better at all the categories. Getting every question right is more important than beating the best time. Funny how everyone has other skills and the minds sprint is great fun to do.
Don't expect to play the game for hours and hours ending up really smart, cause your eyes feel like they're on fire after a while. This game requires to be awake, alert and full concentration.... and boy it hurts when your girlfriend beats you up a few times in a row...
Haven't beaten my own best score of B yet, so still room to improve...
