Query: 4 Year old loves the puzzles...she's learning without realizing it!

The puzzles presented in this are so much fun for my 4 year old, and she's learning math without having to do the standard "flash card" type exercises! She plays this for hours and is committed to making it to the next level on each game. It's a nice change from the character-oriented games she's used to playing. I highly recommend this game!
