This is really good game if you want to know your brain age and train your brain further. The are a few training activities which are quite fun. You can save your brain age once a day and track your progress on a chart.
The only problem is sometimes when you take the test, the touch screen dosent understand what your answer is and it is the same with the mic. Thats the only problem but, if you have neat writting and a clear voice, there shouldnt be a problem.
