hi guys
i'm having a little problem with the puzzles on diophante.fr. it's a french site dealing with math in particular diophantine equations(...). well the problem is that the first few puzzles are right, but in some of them i am forced to use trial and error. can anyone tell me whether he can find a solution using only pure logic.
thanks
dominique

Dominique, I'm a rank amateur compared to the talented solvers who post here. Nevertheless, I'd like to take a shot at some of those puzzles. Could you point to a couple of specific puzzles which required you to use trial and error?

Avertissement :
Tous les problèmes sont identifiés par un niveau de difficulté :

très facile
facile
moyen
difficile
très difficile

This allocates one to five stars (etoiles) to the list above
very easy; easy; medium, hard, very hard.

$ C230. Sudoku
$ C231. Sudoku : grilles n°2 - 3 et 4
$ C232. Sudoku : grilles n°5 - 6 et 7
$ C233. Sudoku : grilles n°8 - 9 et 10
$ C234. Sudoku : grilles n°11 - 12 et 13
$ C235. Sudoku : grilles n°14 - 15 et 16
$ C236. Sudoku : grilles n°17 - 18 et 19
$ C237. Sudoku : grilles n°20 - 21 et 22
$ C238. Sudoku : grilles n°23 - 24 et 25

None of these grids appear to be hard or very hard.
Thus it would be interesting to compare the grading system.
Is a diophantine medium like a SamGJ medium???

C230. Sudoku

Une grille de Sudoku, puzzle très en vogue en Japon, est faite de la juxtaposition de 9 carrés 3x3. Chacun de ces carrés comporte tous les chiffres de 1 à 9 une fois et une seule. Il s’agit de compléter la grille de telle sorte que chaque ligne et chaque colonne du carré 9x9 comportent elles aussi tous les chiffres de 1 à 9 une fois et une seule.

version imprimable du problème C230

Unfortunately the clip board does not transport the actual puzzles!!

The instructions are then repeated for each set of grids.

C231. Sudoku – Grilles n°2,3 et 4 $
C232. Sudoku – Grilles n°5,6 et 7

Ci-après trois grilles distinctes qui font suite aux grilles déjà proposées dans les rubriques C230 et C231.
C233. Sudoku – Grilles n°8,9 et 10

Ci-après trois grilles distinctes qui font suite aux grilles déjà proposées dans les rubriques C230 à C232 :

C234. Sudoku – Grilles n°11, 12 et 13

A noter : ces trois grilles comportent le minimum de données intiales connu à ce jour (17 en l'occurence) avec solution unique.

This suggests that the puzzles have the minimum number of
initial clues - seventeen.

It was such a shame not being able to transport some of the
puzzles from that other site. I was able to post them into a
MS-Word document using Paste Special. Is there an equivalent
way to get them into a post in this forum?

The alternative is to transcribe the grids off the screen onto paper and
then to retype them - an error-prone process if ever there is one!
I would wish to post grids 11,12,13 quoted under C234.
