On February 1, 2006, “Le Matin” will publish a magazine with 50 Sudoku puzzles from Perfect Sudoku.
There will be 30 classic Sudokus plus 20 Sudoku X puzzles.
It is likely that there will be more magazines with our puzzles published in Switzerland.
UPDATE: You can chat about this issue of “Le Matin” in the forum: http://www.djapedjape.com/sudoku/forum/viewtopic.php?t=18
the x puzzle number 44 has a multiple solution (r6c9 can take a 2 and give a complete different solution). Is there an easy way to avoid multiple solutions ? 😉
antoine,
please post the entire solution that you have. I’m pretty sure that this puzzle has a unique solution – but I need to see your other solution so I could tell you where you went wrong.
