Matching game that can be customized with family members recorded voice overs :). Works great for certain period in child development.

So much fun for all in our family from 2nd grader to grown-ups. I think it is suitable for kids starting 1st grade and up, maybe for advanced kindergartners as well... I don't have to delete "funner" games from iPad in order for my child to play this very educational at the same time addictive game. Helps kids to memorize addition/multiplication parts instead of trying to counting every time.

Works well . Does everything it needs to. The science is not wrong. However it's not magic. This means you can't get away with 4 hours of sleep and not be tired. You still need your sleep. But this helps with waking up and getting up

I thought I knew geography, but I still felt slow playing this in the beginning. Great educational fun. If played by children, will make them feel good about themselves in the future.
