5 of 5 stars to Brain games( V. 2) by S. Smith http://bit.ly/HWus7w
Recommended for riddle lovers everywhere! The first few brain teasers were fairly easy to solve. Further into this book the harder the riddles became. I shared some of the brain teasers with my husband and even he was stumped, and he’s great at problem solving. Brain Games Vol. 2 is a wonderful, challenging book!
