My kids have really enjoyed this game and I like the educational aspects without the constant ads that many other games have. That being said, since the last update, the games freeze constantly and/or don't work at all. My husband downloaded the app on his phone and has the same problems. He also paid extra to unlock extra games, but they can't be played due to the glitches. Also frustrating that I was told that all games would be unlocked on my phone if I wrote a review, but nothing unlocked.
