This app is really nice. The animation is happy and eye-catching. Even though there is one link that kids could click on without having a passcode, I appreciate that the bulk of the external links can only be utilized by completing a multiplication math problem. My only thought would be that it would be nice to have maybe a few more puzzles before having to pay to unlock the others. Other than that I am very impressed and would suggest to my friends!
