There are many things that happen in Brain Age, and there are lots of fun games. The first thing that happens in Brain Age is you get a brain age, 80 is the highest and 20 is the lowest. The lower your brain age, the better. If you have a very high brain age, don't worry. You can do many daily training exercises and try to get your brain age down to 20. It will range from a couple of days to a few weeks or a month to get to 20, but once you get there, daily training holds it at a steady age. There are many fun exercises, and there are also sudokus.There is always something to do. But, remember the main purpose is to have fun and get smarter.
