Fun when you have a few minutes to spare. These aren't extremely hard to where you want to pull your hair out but they aren't so easy you don't have to think about what you are doing either. I'd say for ages 10 and up to "now where did I put my glasses this time". Book is 7 1/2 inch × 9 inches. Pictures are all in color and are actually quite beautiful and interesting. No dots/circles etc. that are tedious. Fun way to keep your mind active.
