1. I purchased the full version to continue playing (definitely worth it), and immensely appreciate the lack of obtrusive ads in the free version!Payed for full game and not one new puzzle unlocked..in need of some assistance...issue resolved.
2. After you purchase the app you'll have to download the full payed version as well, if you don't it will not give you the new unlocked puzzles.Very good and helpful for kids.
3. It has improved her puzzle skills.
4. My 2 year old enjoys it.
5. Excellent app.
