This game consists of a daily brain age test, daily brain training and sudoku. I play it almost every day for approx 15 minutes per day. I'm able to take my brain age test and train in that time. After you complete your brain age test and brain training you receive a stamp for that day on your calendar. My brain age was very low at first until I got the hang of it.
The brain training games include numbers and words training. It scores you by your speed and number of items correct. This game is fun right now, I can see it growing tiresome after a few months. I'm sure they will come out with a brain age 4, 5, etc to keep things fresh. I recommend this game, worth the money.
