Wrong things with this app – Einstein™ Brain Trainer Free: 30 exercises to practice your logic, memory, calculation, and vision skills - more effective than sudoku, puzzle, or quiz games Review

I got the free version and I have the chance to play each game only one time. Okay! But when I choose the game it doesn't work, the app closes. Now if I can not TRY the games, the best to do is to delete this app. Upset!
