Title: Just another collection of Medium difficulty puzzles...
Review: I see nothing 'Mensa' about this book. It's a just a big collection of medium-level puzzles. All the puzzles can be solved by inspection only (without any pencil markings or using advanced techniques), and I mean ALL of them!Very similar to Rios's other book 'Black Belt Sudoku'.If you want tough challenging puzzles, I highly recommend you look else where...
