The New Sudoku Players' Forum

[Moschopulus]

Several posts have reported products with sudoku puzzles having more than one solution. I propose we maintain a list of these.
(Wayne, please move to the non-Pappocom forum if you think appropriate)

To start with, I have seen the following:

Bicycle Sudoku Cards (volume 1)

The Times Su Doku tabletop version
http://forum.enjoysudoku.com/viewtopic.php?t=2720

Sudoku volume 3 at http://www.sudokurewards.com/
http://www.setbb.com/sudoku/viewtopic.php?t=515&mforum=sudoku

There must be many in newspapers.
The third one that appeared in the Daily Telegraph (February 12, 2005) had 4 solutions.

The Times Samurai of October 22, 2005.

A Dutch newspaper 'Haarlems Dagblad' December 2005.

The Times Killer Sudoku of 4 February, 2006.
http://forum.enjoysudoku.com/viewtopic.php?t=3097

This is not exactly a multiple solution problem, but in late January and early February 2006, the Daily Telegraph got their ratings wrong and extremely difficult puzzles were published under the rating 'medium'. http://www.sudoku.org.uk/discus/messages/1/549.html?1138917140

Anyone got any others?

[Chessmaster]

yeah some of the electronic handheld sudokus

[gfroyle]

Anyone got any others?

What about the big one emblazoned on the hillside in Britain somewhere? I guess that is probably no longer there..

wow! if they put that in a corn field it would be a "Crop Sudoku"

[Pi]

That sky one sudoku has to take the prize if you think about the effort and cost that must have gone into it only to find that it had 1905 solutions.

Gutted


One in a magazine called "hola" had 158 solutions once.

and of course there is the time that "The Times" (england) reported about the national championships which they organised and they printed the competition puzzle wrongly and it had 2129 solutions

[deam3r]

wow that picture they made in the grass is awsome!

[Chessmaster]

people just have to learn that ture sudokuist like their puzzles to have one solution. on this handheld puzzle that is used it got down to the last four numbers. two of each a 4 and a 5 and any one of them could have gone into each spot. i put them in a way that they worked and it said i was wrong.

[Moschopulus]

What's the name/make of the handheld?

[Chessmaster]

Techno Source makes it and it is just called sudoku. i think that all of the Techno Source sudokus have many soultions

[Moschopulus]

We can add the Texet electronic sudoku handheld to the list:

Hi

I saw a link to this site www.fudoku.com offering various levels of puzzle.

The first one I tried to verify with the Pappocom programme. No luck so I tried Simple Sudoku it told me the puzzle was invalid as there were 4695! solutions. I tried another this time Simple Sudoku said there were too many solutions to count!

I gave up after that!

I found a lot of sites that use www.free-sudokus.com as a source for their sudokus. This site is flooding the web with multiple-solution sudokus.

[shurd12]

Out of the first 10 puzzles in this book, three have more than one solution. The book I have is "Sudoku ?" book #2 out of 4, published by Hinkler Books, Pty Ltd. This is a very elementry book so I guess they are just sloppy??

[Elroy]

A recent online-playable SuDoKu at Puzzle-iT www.puzzle.ro/en/sudoku had 3 solutions;
Where DOES one find valid (free) ones online, anyone know?
