Grille de la semaine #14 [League of Extraordinary Ladies and Gentlemen #1]

Comme annoncé lundi, la grille du jour s'inscrit dans le cadre de la Daily League, dont le nom a depuis évolué en League of Extraordinary Ladies and Gentlemen, pas moins ! De quoi se sentir pousser des ailes...
Chaque semaine donc, 7 auteurs parmi lesquels Tom Collyer, Rishi Puri, Prasanna Seshadri ou encore Fred Stalder publieront une grille de sudoku à tour de rôle ; charge aux personnes souhaitant relever le défi de les résoudre en un temps record puis de soumettre leurs chronos (individuels). De surcroît, à l'issue de chaque semaine, un fichier .pdf regroupant les 7 grilles devrait être publié ; la league étant encore en phase bêta, tout ceci est bien entendu susceptible d'évoluer. Pour plus d'informations, il vous suffit de me contacter ou d'en passer par l'un des auteurs pré-cités, ou encore de visiter la page facebook du groupe.

Ma première contribution sera donc sous la forme d'un Arrow sudoku, variante ayant connu, et connaissant encore, un réel succès. La difficulté de la grille est un peu plus élevée que la moyenne, j'espère qu'il ne m'en sera pas tenu rigueur... Bonne chance !

=> To the special attention of the League of Extraordinary Ladies and Gentlemen : good luck with this not so easy puzzle; I hope you will have fun solving it.

Règles :
Chaque ligne, colonne et région doit contenir les chiffres de 1 à 9.
Au sein d'une flèche, le chiffre situé dans le rond est égal à la somme des chiffres situés sur le reste de la flèche.
°°°°°°°°°°°°°°°°°°°°
Each row, column and region must contain the digits from 1 to 9.
Within an arrow, the digit in the circled cell is equal to the sum of the digits on the rest of the arrow.

  1. I did this earlier today, and I must sadly admit that I had a rather "lucky" path to solution. I inadvertently took a pencil mark to mean a fixed digit. :P However, I went back and took in the solve path and this is quite a wonderful construction. I really enjoyed it, thanks. :)

  2. The fact is I got pretty impressed by your time, considering that, in my opinion, this puzzle was clearly harder than the previous ones. The timings of Tiit, Jakub and others convinced me that it was indeed the case and that you had been incredibly efficient. :-) Good for you; after all, luck is part of the game!
    I am glad you enjoyed the "true" solving path. Arrow sudoku has a vast potential and is one of my favorite variants, so I always try to get the best from it. And I always end thinking there are still many things to do with it...
