the author of this app says:

An easy and fun jigsaw puzzle for little kids. Helps your child develop those all important pre-reading skills.
Starts with only 4 pieces. As skill-level increases, so does the amount of pieces (up to 36).
Also fun for older kids and adults who just want a happy break! It's easy fun and a little addictive...
