To enjoy Brain Age you may have to learn to write again, and that almost reduces the entire experience to frustration.
The Bad: Sometimes it just can't recognize your handwriting, and losing points for that is EXTREMELY frustrating; graphs are limited to one month per time, so you can't follow your progress in a long term; normal and hard modes are mixed in one graph, making your average fall when you try the hard mode.
Good brain training programs, an overall delightful bright sound and the funny doctor's head floating around the screen don't keep Brain Age from being frustrating.
The major problem here is the not-always-good handwriting recognizing system. Every now and then you'll find yourself scratching the screen here and there while watching the time going by without being understood; or being misunderstood, resulting in lost points anyway. In a nutshell, the pieces fall apart because of a structural defect.
A little extra encouragement would have been nice too--like giving prizes for reaching higher age levels or completing sudoku--but it's not there. Add to that the disheartening mix between normal and hard modes in the graphs generation and we've got more problems than qualities.
On the other hand some training programs like Low to High and Head Count and some tests from the brain age check feature like Connect Maze work pretty fine and are well-executed ideas, but that only sum up for a final disappointment feeling.
In the end there's only a bitter taste in your mouth because it's easy to recognize a good opportunity wasted under technical issues.
