I have a few books on solving Sudoku in my collection, some I bought on my own and some presented to me. Here are short reviews of these books.
There are two Teach Yourself books and two by Carol Vorderman.
First, Teach Yourself Sudoku by James Pitt
This book has only 16 pages of instruction on how to solve Sudoku and covers only the basic technique. So this is only good for very basic beginners. The rest of the books are just Sudoku puzzles (156 of them to be exact) of various levels of difficulty. Personally, I do not like the print of the numbers in the puzzles, they are too small for the cell size. (Is it because of this that I found myself struggling in the very first puzzle in the beginner's section??) My verdict would be to give this a miss and if you like Teach Yourself series, go for the one below, it gives better value for money, in my opinion.
Next, Teach Yourself Advanced Sudoku and Kakuro by Nick Afka Thomas
In this book the instructions are more detailed and in depth and covers right up to the tough nuts in the first 118 pages. These are interspersed with puzzles that uses the technique described earlier. There are only 60 puzzles of the normal Sudoku but you can always get books or magazines with just Sudoku puzzles if you need more.
Next there are 36 pages on Kakuro, another popular Japanese number puzzle that ranks just behind Sudoku. And finally there are 28 pages on Killer Sudoku, which is a combination of Sudoku and Kakuro. This uses the Sudoku grid but has no numbers given in the cells but just some arithmetic clues as in Kakuro.
To me this is definitely a better buy than the earlier Teach Yourself Sudoku book since you get more detail solving instructions and also something more that you can move on to once you are getting a bit tired of the normal Sudoku and want something for a change.
The next two books are by Carol Vorderman.
First, the simpler of the two. The UK version with the title - How to Do Sudoku.
This is the US version with the title - Master Sudoku.
As the blurb on the cover says "Step by step, I will show you how to be a Sudoku master" so Carol covers all the techniques, step by step. She even shows the steps from start to finish on doing 4 levels of Sudoku, easy, medium, difficult and super-difficult. But whether you'll be a Sudoku master is debatable. This book is good for the general Sudoku solver from beginner upwards. There are also 200 Sudoku puzzles.
Next is a bit more advanced. The UK version is titled "How to do Extreme Sudoku"
The US version is simply titled "Extreme Sudoku"
This book is more for the advanced Sudoku addicts as it summaries the techniques covered in the first book within the first 50 pages. This is then followed by 175 Sudoku puzzles of the more difficult variety. Next comes the chapter on Squiffy Sudoku (odd shaped grid) with 25 puzzles included. This is followed by 25 puzzles of Sudoku 16, which is Sudoku using 16 numbers on a 16 x 16 grid instead of the usual 9 numbers.
The last quarter of the book is devoted to Killer Sudoku with 48 pages on "How To" followed by 16 pages of a start to finish example. Finally there are 75 puzzles of Killer Sudoku for you to practice what is taught.
If you just want to do the normal Sudoku, go for the first book but if you want to try something different or prefer tougher Sudoku puzzles, then go for the second one.
And how does the Teach Yourself Advanced Sudoku compared with this by Ms. Carol? If you judge a book by its cover, I would go for Ms. Carol anytime. Who wants to look at a bald-headed man scratching his head when you can watch a long hair brunette? (With due apologies to all bald-headed men out there!) Well, her book uses simple language, is less technical and thus less complete when compared to the Teach Yourself book where you'll learn jargon such as X-wing, Swordfish, Jellyfish and so forth. For a beginner and intermediate solver, I would recommend Ms. Carol but if you are a purist and want to learn and apply all the advanced Sudoku jargon, go for the one by Nick.
There is one more Sudoku solving book in my collection. And this is one to own if you want to impress your friends or insult your enemies and the title is Mensa Guide to Solving Sudoku by Peter Gordon.
This has all the Sudoku jargon you want plus more including the exclusive Gordonian Logic; it's doesn't carry the Mensa name for nothing. It has 86 pages of solving techniques with 96 puzzles in between for practice. After these there are 704 (yes, 704) puzzles to keep you busy for some time. So if you are just after classic Sudoku, this is the book for you. You'll also get a reprint of the first Sudoku-type puzzles from Dell Puzzle Magazine called Number Place.
So in summary, get the Mensa book if are interested only in classic Sudoku. If you prefer something more such as Killer Sudoku, then go for the Teach Yourself Advanced Sudoku. For lighter reading, get one by Carol depending on your level of interest. You can forget about James.
As in any trade, you cannot become an expert by just reading books. You need to practice, practice and practice. So you need to solve, solve and solve. But don't forget also to enjoy solving your Sudoku.
