Query: Not as much fun as Brain Age or Brain Academy

As an adult gamer, I didn't care for this game. I have tried Brain Age and I think it's so much better than Brain Boost: Gemma Wave. Brain Boost is just a memory game, period. There is nothing else to do on it except just to test your memory. 3 ways to test your memory, numbers, pictures and colors. Each test was pretty long. After awhile I got bored with it quickly. For variety, get Brain Age or Brain Academy.Even my nephews ages, 7 and 8 didn't care for it either. They liked Brain Age better.
