Sudoku book

The Book of Impossible Sudoku is an ideal gag gift. It contains 100 different Sudoku puzzles that all look possible at first glance, but turn out to be impossible to solve if you dare to try!

From the final page of the book:

If you've attempted to solve any of the Sudoku puzzles in this book, you may by now have noticed that they are rather difficult to complete; in fact, all of the puzzles in this book are truly impossible.

Every puzzle has been derived from a set of valid Sudoku puzzles. Each valid puzzle consists of 24 initial values and was analysed to ensure that there is a unique solution.

One of the numbers in each valid puzzle was then altered, such that the apparent integrity of the puzzle was preserved. This simply means that the change did not result in more than one identical number appearing in the same row, column or box. Each new puzzle was exhaustively analysed to ensure that there were no possible solutions.

All puzzles that turned out to have no possible solutions were included in this book. The process of generating the impossible puzzles was carried out automatically using a Java program, and exported to EPS format using the EpsGraphics2D package at www.jibble.org.

So — you may now be wondering, "What is the point of The Book of Impossible Sudoku?" Well, you're reading this page, so it's clearly got your attention somehow.

This book was originally envisaged as a joke — a gag gift that you can give to your Sudoku-loving enemies; or maybe you simply want to keep a copy on your bookshelf to taunt your guests? Either way, you can enjoy watching people's frustration as they attempt to solve the puzzles in this book, only to reach the inevitable deadlock where they are unable to proceed — possibly believing that they have made a mistake somewhere along the line.

Of course, the nature of this book will become apparent when your victims stumble upon this page; however, the solution is simple: find a pair of scissors and you will realise why this is the last page in the book...

PrintSudoku.com offers three free printable Sudoku books with 25 puzzles each. Book one features 25 very easy Sudoku puzzles, book two has 25 easy Sudoku puzzles, and book three has 25 Sudoku puzzles of medium difficulty. The books are in Adobe Acrobat (PDF) format.

Electronic Handheld Sudoku Game

Despite Sudoku's recent boom in popularity the game itself has been around for yonks. So it's rather surprising that nobody has ever bothered to produce a handheld electronic version. Well, guess what? They have now, and it's here at Firebox!

Electronic Sudoku is, as you may have surmised, a handheld LCD version of the world's favourite numbers puzzle, and it's just as fiendishly addictive as the printed game seen in every newspaper in the land. The difference here is that you won't get your mitts grubby or be distracted by pages of non-stories as you play.

If you're reading this and wondering if Electronic Sudoku transforms into a radio controlled spacedog, fires edible scorpions or plays DVDs, then the answer is no. So how come Firebox is selling it, then? Well, the fact is Sudoku really is as ridiculously compelling as everyone says. And this electronic version might not feature dive-bombing aliens or mallet-happy plumbers, but it's just as unputdownable as the Donkey Kongs and Galaxians of this world.

Basically, the object of Sudoku is to solve mind-mangling number puzzles and enter your solutions on a crossword-style grid. Yes, we know that sounds about as interesting as... er, solving number puzzles played on a crossword-style grid, but believe us, the minute you start playing you'll be hopelessly hooked. A bazillion Carol Vorderman fans can't be wrong, can they?

Indeed, Electronic Sudoku has impressed us so much we're selling two different versions: the standard pushbutton/joypad edition features over 750 puzzles, 3 skill levels, a puzzle timer and sound effects. Perfect for Sudoku fans on the move. The ultra-chic touch screen edition contains over 100,000 puzzles and features 2 modes with 4 skill levels a piece. Simply input your solutions via the easy-to-use touch screen stylus. Ideal for roving Sudoku sophisticates.

If you're eager to sample the delights of Sudoku but would sooner be caught reading Anorak Weekly than seen travelling with a puzzle book or a pile of papers, Electronic Sudoku is most definitely for you. In fact, old-style Sudoku's number could well be up!

Electronic sudoku

Sudoku (Su Doku) is a logic based placement puzzle, sometimes referred to as Number Place in the United States and Canada.

The New York Times Touch SuDoku contains more than 800 puzzles, all selected by world-renowned puzzle expert Will Shortz.

The aim of the puzzle is to enter a numeral from 1 through 9 in each cell of a 9×9 grid made up of 3×3 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 logic. Its grid layout will remind you of other newspaper puzzles like crosswords and chess problems.

Sudoku puzzles:

Sudoku puzzles do not require any knowledge of mathematics to solve. Move mouse pointer over the sample puzzle to see the solution. However, Sudoku does require logic and reasoning. The use of numbers offers one method of identification – letters, colors, symbols or anything else can offer identifiers for the cells. Some children's games use animals.

Sudoku is a puzzle with a grid containing nine large blocks.

Each block is divided into its own matrix of nine cells. The rules for solving Sudoku puzzles are very simple: each row, column and block must contain one of the numbers from "1" to "9". No number may appear more than once in any row, column, or block. When you’ve filled the entire grid, the puzzle is solved.

How to Play Sudoku
