Great app

My kids love it but it's playing all of the tunes from the games at once! Drives me crazy. Great app though.

Fun learning

My child is can't do all of the activities yet as she's on the younger side (4.5), but she'll grow into the others, and she really enjoys those she can do (grandpa's pies and memory). She sees it as a 'fun' app rather than an 'educational' app- winning in my book :)

Witty and well-structured

Witty and well-structured games. I recommend any app with ‘Eggy’ in its title, as every one we have has been excellent. They are easy to use, the programming works well with no glitches, and best of all, teach good maths.
