Non-expensive and solid, but needs more variety.
Brain age is a game that gives your brain excersises by making you do various brain excersises like speed math, reading out loud, puzzles and more. You do at least one excercise a day, and the game records your progress, and your brain age.
As I played it, I felt that it was really helping in some aspects, basically because I improved each time. However, if you are feeling tired, or not in the zone, you will probably get a very old brain age, as opposed to if you are feeling sharp and rested.
The game also gives you lifestyle tests on how to improve your brain age (read billboards as fast as you can on the way to work, count your brush strokes when brushing your teeth). Hoestly, these are helpful, but if you are not into that sort of thing, or you find it annoying, you will not like the activities, and the game will proabably get old quick.
Once you get an ideal brain age, 20, there is not much more to do, except to keep practicing and keeping it.
The graphics and sound are average, they are what they need to be, surely nothing more. They serve their purpose. They are not very flash, but if they were too flashy, that might detract from the game's purpose.
This "game" may not be for everyone, but if you are open to trying it, and don't mind spending 20 bucks, I suggest you pick it up!
