[Bug 690989] Re: Every sudoku puzzle should have only one valid solution

 

A comment left on the upstream bug:

https://bugzilla.gnome.org/show_bug.cgi?id=656613#c1

1. This report is poorly substantiated.  If you've found a game that doesn't
have a unique solution, you should be able to explicitly show that.  For
example, you could fill in all of the squares, then identify which entries can
be swapped to yield a different solution.

2. The solver at http://www.sudokuwiki.org/sudoku.htm has a "solution count"
feature that returns 1 for this puzzle.  See
http://www.sudokuwiki.org/sudoku.htm?bd=010406309000030850000000060060500702250607013407002090070000000094050000603904070

Title:
  Every sudoku puzzle should have only one valid solution

Status in GNOME Games:

Bug description:
  Binary package hint: gnome-games

  Hello,

  Per my understanding of Sudo Puzzles, each puzzle should only have one correct answer (Unique Solution).
  If there is more than one solution the puzzle is considered "not properly formed".

  On a personal level I feel that its very frustrating that the Sudoku
  puzzles comes to a point where I have to "Quess" which number to pick,
  as this is not Logical. And Soduko is suppose to be a logical game.

  Please refer to:
  * http://en.wikipedia.org/wiki/Sudoku
  * http://www.dailysudoku.com/sudoku/faq.shtml

  Also refer to my attachement of a game I can not complete with out
  guessing.

  Request:
  Please fix the Sudoku that comes with Ubuntu to allow me to Force it to give me only "Properly Formed" one solution puzzles.

  Regards,
  Christoff Erasmus
