My 11 year old brother was visiting a few weeks ago, and while the adults were talking he was bored out of his mind. He found my book of Pic-a-Pix puzzles on the coffee table and asked me to teach him how to do them. It took a couple practice puzzles for him to get the idea, and then he went bonkers doing puzzles! He loved them!
For kids and adults alike, these puzzles are a blast. :)
