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)http://forum.enjoysudoku.com/viewtopic.php?t=2836
The Times Su Doku tabletop versionhttp://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.http://forum.enjoysudoku.com/viewtopic.php?t=3097&start=14
A Dutch newspaper 'Haarlems Dagblad' December 2005.http://forum.enjoysudoku.com/viewtopic.php?t=2464
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?
