(Well, they are difficult puzzles but ...)

(Toughest ever)
The ratings in this little gem suggest that the puzzles range from "difficult" through "very difficult" culminating with a collection of fiendish puzzles. True enough, but ...

The trouble with this set of puzzles is that Nishio's solutions focus too often on a series of the simplest of the advanced skills - box, row and column claims; and hidden doubles, triples and quadruples. Even in the "fiendish" puzzles, the solutions only rarely venture into the use of such tools as conjugate pair chains, x-wings, swordfish, or xy-chains. And, in those few instances that these tools are required to squeeze out the solution, the entire back of the puzzle is typically broken by a single application of the more advanced technique.

I confess that I haven't completed every solution in the book yet but I haven't found a single instance of a puzzle that required two really advanced techniques to reach a solution.

That said, I'm happy to recommend this particular book to advanced Sudoku freaks who enjoy a challenge. Of particular interest is the small set of Sudoku variations included at the end of the book. In the context of this review, it would simply take too long to describe the rules of the variants that Nishio has created but, (trust me here) these are far more devious and challenging than the regular puzzles.

Well done, Mr Nishio. I've still got more enjoyment to go in this book and I'd happily pick up any other puzzles books with your byline.

These are very challenging puzzles. They can be lots of fun if you're willing to be patient and persistent.
The continued success of Sudoku means that there's a new breed of Sudoku puzzler: experienced, resourceful, and ready for puzzles that transcend the rote specimens one encounters in the daily newspaper, online, or in mass market magazines. It is this sector
of puzzle solvers that grows every day, and the sector for which Vertical has conceived its line of Sudoku books.

Sudoku is a logic puzzle that was originally created in the U.S., but which achieved its popularity in Japan. Hence the Japanese name. The goal is to fit the numbers 1 through 9 into blocks of nine squares, using each numeral only once. Until recently, these basic Sudoku puzzles have been created with simple computer software. Easy to create, yes, but formulaic
and unchallenging. The puzzles inSudoku Hellare conceived by Japan's greatest puzzle mind, Tetsuya Nishio, who takes extreme pleasure in creating his puzzles as devilishly devious as possible. And, as with Vertical's previous collections, there are an array of Sudoku-inspired variant puzzles inSudoku Hell, which offer unique new ways to entertain and drive puzzlers mad with pleasure.

(Great for the Novice)

(Great Sudoku Book for All Levels)

(COULD HAVE GONE FARTHER)

(Good for non-experts.)

(GOOD INSTRUCTION AS WELL AS PUZZLES)
I had never done a sudoku puzzle so I bought this book and loved it. So much so that I'm now online to get my next Vorderman Sudoku book.

Her method takes you through 4 levels of difficulty explaining techniques for solving at each level and diagramming solutions as they are worked out.

She also has scores for the puzzles which adds a little spice. For example, if your time is less than X minutes you get Y points, etc. The harder the puzzles the longer you have to solve them, but the times are often pretty challenging.

Interestingly, I found that I trusted Carol to provide solvable puzzles. Some of the books I've picked up have puzzles that don't seem to be solvable - one of them even had wrong anwers in the back, i.e. the grid in the answers didn't match the grid given for the puzzle.

I recommend this book to anyone wanting to learn how to solve Sudoku puzzles.
*****
This is a great sudoku book for all levels, but especially good for those who wish to increase their sudoku proficiency and MASTER sudoku. There are 200 puzzles, only one to a page, printed large enough for marking up. There are places to record your time, too, and you can accrue points based on how quickly you can do a puzzle. This is nice, because although I prefer difficult puzzles now, it's fun to go back and do an easy one faster and faster. There are different techniques involved in the different levels of puzzles and timing them makes them all continue to be challenging.

If you're a beginner, you can start out with the easy puzzles and work your way up. There are medium puzzles, too, as well as difficult and super-difficult. There is plenty of technique instruction, and there are many examples, so this could serve as a first book for adults. It was not my first sudoku book, but it is still one of my favorites, and I find myself going back to it again and again.

Highly recommended.
*****
I WAS HOPING THAT SHE WOULD HAVE GONE INTO THE SOLVING OF MORE DIFFICULT PUZZLES. HOWEVER, I THINK SHE DID A GOOD JOB IN SOLVING THE MEDIUM PUZZLE SOLUTIONS.
Good basics. A good springboard, and you can go to more advanced techniques later. Her favorite epressions are "slicing and dicing." Took a while for me to figure out that all she's telling you is to look horizontally, and vertically.


VERY HELPFUL. SHE DOESN'T LEAVE YOU WONDERING WHAT CAN I DO, OR TRY, OR WHERE TO START. IT'S ALL THERE FOR BEGINNER OR DIFFICULT PUZZLE SOLVER. THE ONLY BOOK OF IT'S KIND OUT THERE ...I.B.E. MASS.

(Disappointing implementation)

(Sudoku-Play at Joe's)

(moderately decent game, horribly inconvenient)

(Great Brain Food!)
I bought this game after looking at several choices on store shelves, and deciding this was the best choice I bought it. I immediately discovered that my choice was a poor one.

On the surface, this looks like a very capable version of computerized Sudoku, which is exactly what I was looking for. I wanted something with LOTS of puzzles, some variety in difficulty levels, the ability to print, and an intuitive GUI for playing. This version does all four of these. For that, it is to be commended - it has the features most serious players will desire.

That said, the implementation and additional features make this game a less than ideal choice.

One of the most annoying features is that it requires the CD to be in the drive when playing, and for some that is inconvenient.

More of an aggravation, though, are the sounds for the game. There is background music that serves only to be distracting. There also happens to be a voice element to announce the numbers as they are placed - the voice sounds very much like you would imagine for an anime schoolgirl that's entirely too happy for her own good. I cut the speakers for that one. With no sound, gameplay is a lot more pleasant and is acceptable.

The game allows the player to show mistakes during play. HOWEVER, once that setting is turned on, it is not possible to turn it off except when there is no game being played. For players that are learning to play, this is fine, but once a player knows the lay of the land, either the current game needs to be quit in order to toggle this setting, or it needs to be turned off at initial launch.

In the box with the CD was a bright orange card that stated that there was an update to the game available to patch a problem with printing. While I realize that this likely went in the box after the golden image was sent to the duplicator, it still is annoying to find that your brand new game is already outdated.

I looked for another Sudoku game the very next day and found a better one with more features, a better interface, and a smaller price tag. If you want a good Sudoku game for your computer, I cannot recommend Play at Joe's Sudoku Challenge unless there are no other options available. Your money is better spent on other choices.
the games cannot be identified so that you can save them and do later. I like to print out the blank game, then print the possibilities and then see the answers. I tossed this product as unusable for me.
Play at Joe's Sudoku is a moderately decent version of Sudoku, not half as nice as the shareware version I had downloaded. I bought this version because I wanted a CD, rather than paying for a software key that could get lost. Boy did I miss the point! This game REQUIRES the CD to start. Who does it that way today and why? I like to play games like this while I'm busy with other tasks, like burning copies of home movies for relatives. Unless I remember to start the game first, I'm out of luck. And I've got to keep that CD on my desk, available in case I want to play it. In other words, I DON'T play it, I'm back to playing Solitare. I spent $20 on a totally worthless game.
I got hooked on Sudoku when I traveled to the UK on business. Everyone there was doing puzzles daily. I got caught up in the madness! These puzzles are great for keeping your mind sharp and are a great exercise for school children to learn logic and deduction. Not only am I hooked now, but my wife, 9 yr old, 12 yr old and 16 yr old all take a daily dose of Sudoku.

I had bought Sudoku software while in the UK, but the puzzles were not true Sudoku puzzles- meaning that they fudged the puzzle and many of the puzzles could not be completed correctly. The Play at Joe's puzzles are formulated in the same way as the Japanese masters have done for centuries. Play at Joe's Sudoku Challenge is authentic and addictive!

The Sudoku Challenge is a great game for anyone who loves crosswords, word searches, mahjongg, brainteasers, solitaire or any addictive game. You can even print out puzzles to take along for your commute. Highly recommended game!

Sudoku Challenge is the Japanese numbers game that's driving everyone mad. We guarantee that once you've tried one Sudoku puzzle, you'll be hooked! The deceptively simple goal of Sudoku is to fill in the missing numbers in a 9x9 grid. All it takes is some brains and concentration. Maybe it sounds easy, since it doesn't require any calculating or special math skills -- but trust us, this challenge to your logic and reasoning will keep you busy for hours!

(Of course you can pencil-in candidates)

(Not as good as the original)

(Not as versitile as other versions of SuDoKu)

(Perfect computerized Sudoku)

(Good, but not great)
The review given here by Professor says that Classic Sudoku does not allow you to "pencil-in" the possibilites for each entry. He says that the program does that for you. This is not true. You can add your own possible numbers which appear in a smaller size than the final one. The game does not have that automatic "fill-in" feature he mentions--you'll have to do the work yourself. Professor must have been reviewing another Sudoku product and by mistake included it here.

I am very happy with my purchase. This software is easy to use, it has several levels of difficulty...it fulfilled my expectations.

With the original version, multiple games could be printed on one sheet of paper to complete at your leisure. In this version, more trees are killed because you only have the ability to print one game per one sheet of paper. Other than that, this game software is what I anticipated and I am satisfied with the product.
I was very disappointed with this CD, as I was hoping for the ability to add and erase my own pencil notes rather than only having the choice of the program adding them or not.
This one is the best of what I've tried. It allows you space to put in trials before actually entering the answer. Best of all it doesn't clutter up the program with a lot of extraneous graphics that slow down the program and shrink the playing area. However, it does have nice graphics and a choice of backgrounds so it is a pleasant environment.
There are 4 puzzle levels: easy, medium, hard and impossible. There are 5 "themes", but these are only background frames. There are settings for error-checking and timing. The numbers are large and boldface, easy to see/read. There is a "flash me" setting for hints if you get stuck. There is no annoying "theme song" to be silenced. The only "sound effects" are beeps for errors and at completion of the puzzle, but it would be nice to have some kind music or sound when a puzzle is finished correctly. (The bells-drums-shouts at puzzle end on the USAToday and Washington Post online Sudoku games are fun -- a sort of Pavlovian trigger which makes one want to solve another puzzle!) You get good value from this CD version.

(Buttons small)
There are too many things to do before playing a game or checking an entry. The buttons for everything are small and the writing on the instructions is very tiny. I did not like it and gave it away.
Our Super Electronic Handheld Sudoku puzzles are all top of the line. Each model includes over 1,000,000 puzzles built in. We use a super high resolution large LCD display for easy viewing with Indiglo backlight built into four different models (sk-838, sk-888, sk-898, sk-8011) for playing in the dark. 3-5 Levels of play (depending on the model) - the number of givens goes down with each higher level. Each Sudoku game comes in sealed packages with instruction booklet. Please see below for exact model specifications, colors and dimensions. sk-683 Features: Size: 5.4" x 3.3" x 0.9" Screen: 2 x 3" 3 modes: time, date, alarm clock Millions of sudoku games, you can select any game difficult or easy as you like Functions: drafting function, reading function, redoing examination function, and double-mode operation Power supply: 2 x AAA (not included) Color: silver, blue, green or purple (random color) Sudoku is a logic-based placement puzzle, also known as Number Place in the United States. The aim of the puzzle is to enter a numeral from 1 through 9 in each cell of a 9 x 9 grid made up of 3 x 3 sub-grids (called regions), starting with various numerals given in some cells (the givens). Each row, column and region must contain only one instance of each numeral. Solving the puzzle requires patience and logical ability. Its grid layout is reminiscent of other newspaper puzzles like crosswords and chess problems. Although first published in 1979, Sudoku became popular in Japan in 1986 and took the United Kingdom by storm.
