Adorable! Allows you to use 3 of the characters as much as you want, NO ADS! (Thank you!!) You can unlock the rest with a small in-app purchase. (There is also a parental gate to prevent accidental purchase of the full version. I will definitely recommend this to others- the characters are brightly colored, engaging and appear developmentally appropriate. I like how you can change the settings to toggle between either tapping or dragging to build the pieces of each animal puzzle- not only is the “tap” option good for little ones, it is also good for children with differing abilities. Love it!
