Title: Awful
Review: These puzzles are not logical, they are stupid. The answers in the back of the book cannot be counted on to be correct. E.g., Game 32 has an incorrect answer in the back of the book. I'm a mathematician by training. When the GRE test had an experimental test on logical thinking, I scored in the high 90's. I'm good at this kind of puzzle and enjoy doing these, but this set is awful. You might try works by Martin Gardner instead.
