Sudoku for Experts

It's great to have puzzles which concentrate on a particular technique so you have a chance to add new techniques to your armoury, and to understand how the ones you have developed yourself fit into the nomenclature of others. I started on this book, then sought out the prequel, and am yet to finish this, but looking forward to it.

First class exercises for intermediate/advanced sudoku addict, but not a workbook for those hoping t

Paul Stephens's collection of one hundred fifty new puzzles will keep sudoku addicts going for a long time. Even the easiest ones at the beginning offer some significant challenges, if not with the puzzles themselves but with the time limitations he provides for "improver," "expert," and "genius." The puzzles are unusually well devised, and they are printed on top quality paper, so that if you, like me, may have to do a particularly challenging puzzle three times before you finally figure out all the tricks, you can erase and then re-do, without any problems. Erasing is clean, without any residue left on the eraser, and the puzzle is so "new"-looking that I defy anyone to realize that this is a re-do. I've been a sudoku addict for about three years, doing at least one puzzle a day, and I was hoping that this book would provide me with some the techniques that the really great puzzle solvers use to work on a solution when they hit gridlock, but I was disappointed, not with the puzzles, but with the author's unusually arcane descriptions of the sudoku strategies which most of us do automatically. Spending time trying to translate what I have been doing automatically, into the author's pre-established vocabulary is annoying, when the need to do this is based on the author's unusual labeling and not on the technique itself. I finally decided to just do the puzzles, the way I normally do. I've learned a lot about the math and strategy from doing the successive Tom Sheldon series (which I strongly recommend, regardless of level of expertise), and knowing the complex names that Stephens applies to the usual sudoku strategies is not important to me. In fact, I find most of them LESS helpful than just following instinct. This is one of the best books I've found in terms of the quality of the puzzles, but if you are hoping to improve your skills as a result of this book, you may be disappointed. The author provides graphic examples for the strategies he suggests, but the scope of these and the ability of the puzzler to apply them to future use is so limited that I finally gave up. (I've never quite figured out what the A and B in his examples represent because the whole puzzle is not shown, and I can't see his suggestions in total context!) I've found that the techniques I already have from the Tom Sheldon series have stood me in good stead, however, and I have totally enjoyed, and even admired, Stephens's puzzles. n Mary Whipple The Big Sudoku Brain Workout: 150 Puzzles for a Younger Mind, Book One, by Tom Sheldon Sudoku Genius: 144 of the Most Fiendish Puzzles Ever Devised, Book Two, by Tom Sheldon Sudoku Master Class, Book Three, by Tom Sheldon Will Shortz Presents The Little Black Book of Sudoku: 400 Puzzles (Will Shortz Presents...)

A path to Sudoku enlightenment for advanced learners!

What an absolutely marvelous idea for Sudoku addicts like myself! Paul Stephens, the author of this marvelous little puzzle compilation, explained the idea beautifully in his foreword: " ... it can sometimes be hard to find the right puzzle for your skill level, or to give you practice in a particular solving technique. I've aimed to address that problem with this book. It contains 150 puzzles, hand-picked for the techniques needed to solve them. Each puzzle has a description giving you a guide to the major techniques required, along with tips on where to look within the puzzle and what to expect next." The puzzles are graded from moderate to fiendish (and trust me here, fellow puzzle solvers, "fiendish" in this book means EXACTLY what it says!) and take you through the simplest gridlock busting techniques to the most complex. Each technique (with a few variations) is briefly explained in the opening pages but it takes solving the actual puzzles to switch on that "aha" light bulb, to come to understand how the technique is applied in a full puzzle and to see how it fits into the context of a developing solution. Stephens covers an enormous range of puzzle solving techniques including: Crosshatching Single candidate squares Single square candidates Virtual crosshatching Naked pairs, triples and quads Row, column and box claims Remote pair chains Non-unique rectangles Bivalue Universal Grave X-wings, Swordfish and Jellyfish XY-wings XYZ-wings Conjugate Pair Chains Multi-colouring XY-chains Forcing chains and loops Nishio Nice Loops Even the easiest puzzles in the book (which were, in fact, somewhat lower than the solving ability I had already achieved) were made more challenging and more pleasurable in the doing because Stephens put in three solving time estimates - one for "genius", one for "expert" and one for "improving solvers". I got the greatest kick out of trying high speed solving to see if I could achieve the "genius" time estimate. In the earliest puzzles, I could come very close to the "genius" time and invariably beat the "expert" time. But it didn't take long for Stephens to feed me a dose of humility. By the time I got to the middle of the book, I was feeling more than adequately challenged and felt that I was improving my skills with every puzzle that I looked at. This is NOT for beginners nor could it by any stretch be considered a "Sudoku for Dummies" but if you're already a competent solver looking for challenges and a way to stretch your puzzle solving abilities with more esoteric techniques, then look no further than this delightful book. Highly recommended. Paul Weiss

An irreplaceable book for those wanting to work on strategy

I'm astonished by the negative reveiws of this book -- the only explanation I can see for them is absolute ignorance as to the purpose of the book. So, as a reminder for those who left negative reviews as to the authors stated intent, I'll copy-paste an excerpt from the introduction: "Before the puzzles you'll find a 10-page quick reference guide to the solving techniques you'll need to complete this book. This isn't a full sudoku-solving tutorial (for that try my book Mastering Sudoku), but should be enough to jog your memory" (I.e. the book isn't meant as a replacement for a more comprehensive strategy tutorial...)
