5 stars: Fun with a variety of games to test and strengthen mental skills. The games start out easy and then become more difficult. Lots of levels to move up to. There are ads but there is a way to remove them. I would recommend this app to anyone who wants to sharpen their brain skills while having fun doing it!
4 stars: I love it, but the Multitasking challenge gets stuck. It does not go further than level 3. The screen freezes when I am supposed to go to the next level. All the others I have played so far work well and I enjoy them very much. M not sure if my brain function in other things improves, but I see improvement in these challenges.
5 stars: I love this game! It's challenging and it's easy to lose track of time when playing this! It just has WAY TOO MANY ADS and it lags a little bit, which sometimes results in me tapping the answer again and when i do the next thing pops up and puts that i got the answer wrong but that answer was for the previous question. Other then that like i said i love this game!
4 stars: This is app has great games and excercises for improving your mind and thinking skills. However, there are way to many ads. I can barely keep myself from uninstalling this app everytime i use it, due to the fact that i am forced to watch an ad everytime i fail or pass an excercise. So, its a good thing i find the excercises entertaining enough and the games fun enough to put up with the ads or it would be gone.
4 stars: I really like the app....
