hopefully lighten the mood for some of you. It should also be a somewhat
easier puzzle than the previous ones.

Opportunely, Cracking the Cryptic recently released a new app dedicated to Killer Sudoku (<a href="https://store.steampowered.com/app/1471910/Killer_Sudoku/">https://store.steampowered.com/app/1471910/Killer_Sudoku/</a> - also available in other stores) and I have had the pleasure of contributing a large number of puzzles, some of which are available at launch while others will get added to the app in future updates. All the puzzles therein are handcrafted and several other talented authors have contributed, so I encourage you to check it out.</p><p style="text-align: justify;">You may rightly feel a bit uneasy at the thought that there are so many killers on the loose... But fear not, they will not stay free much longer. Actually, some of them have already been caught and locked up in a high-security prison, an overview of which I provide thereafter. Now that I think of it, let's hope nobody uses this classified document to plan an escape...<br /></p><p style="text-align: justify;">You can solve this puzzle online using the F-Puzzles interface: <a href="https://f-puzzles.com/?id=y66n7wqw">https://f-puzzles.com/?id=y66n7wqw</a><br /></p><p><br /></p><div style="text-align: center;"><b>Rules :</b></div>

This here puzzle is just another regular Killer Sudoku. Note that it has only 11 cages, which is not the minimum possible but still a rather low number; I have been making a few such puzzles lately. It is also pretty hard and a few years ago I would probably not have published it here, but since there is an evergrowing public for this kind of puzzles, I feel comfortable sharing it. It is definitely not a masterpiece, but there are a few interesting deductions to make along the way.

It has been more than four years since last I shared a puzzle here. Not that I stopped making puzzles, mind you - I have been contributing to sudoku magazines, competitions and more - but circumstances forced me to take a break with puzzlemaking during the fall of 2016, and I simply never found the motivation to resume my activity with the blog. My life was hectic back then - it still is - and forcing myself to make puzzles every week could not fit in it, and still cannot. For nearly four years I focused on making a living out of selling puzzles (with limited success), and it is only recently that I felt ready to try something new.<br /><br />Following the postponement of the World Sudoku Championship 2020 and encouraged by the success of the now world-famous Youtube channel Cracking the Cryptic, I recently tried my hand at making sudoku videos with a focus on speedsolving, since there were almost no such videos available anywhere and I felt like I could fill this gap efficiently. I currently release between one and two videos a week on the Youtube channel <a href="https://youtube.com/channel/UCuiNWH9CJdqRPt52CcQrBOA" target="_blank">81 Cells</a>, and at the moment this is the best place to follow me. I also do livestreams occasionally, on <a href="https://www.twitch.tv/81cells" target="_blank">Twitch</a> rather than Youtube since the Twitch interface is infinitely more friendly for this purpose. The Youtube channel is where you want to go to watch spectacular solves of spectacular puzzles, while Twitch streams are meant to be a bit more casual and informative - at least they should be once I manage to grow a bit of an audience... and to fix some unfortunate issues with my Internet access.<br /><br />Seeing how my previous attempt at sharing sudoku-related content once a week ended, I cannot say for how long I am going to keep this going; but I feel like this is as good a time as any to try. Of course the core of my professional activity remains puzzlemaking, but hopefully this will help me find a balance between the crafting and solving halves of my passion for sudoku.<br /><br />I have not planned to resume publishing puzzles here on a regular basis, but I might share one once in a while. I am going to publish one right now, at the very least. Be warned: though a most common variant, it is rather on the tricky side of the difficulty scale! It comes in two versions, the original one and, purely for the sake of it, a second one that is more visual. Pick the one you prefer. Here are two links to solve the puzzle online using the F-Puzzles interface designed by Eric Fox: </p><p style="text-align: justify;"><a href="https://f-puzzles.com/?id=yxq7d27h">https://f-puzzles.com/?id=yxq7d27h</a> ("minimal" version)</p><p style="text-align: justify;"><a href="https://f-puzzles.com/?id=yy2stfef">https://f-puzzles.com/?id=yy2stfef</a> ("elephant" version)</p><p style="text-align: justify;">Finally, here is a link to Simon Anthony's solve of the puzzle on Cracking the Cryptic:</p><div class="separator" style="clear: both; text-align: center;"><iframe allowfullscreen="" class="BLOG_video_class" height="266" src="https://www.youtube.com/embed/RoVz97O0A_8" width="320" youtube-src-id="RoVz97O0A_8"></iframe></div><p>

<br />
<div style="text-align: justify;">
Then came the puzzles. There is not much to say here, at least regarding my performance; since I did not want to risk making my injury worse, and as I barely had the time to read the instruction booklet before the competition, my intention was to play even more casually than I usually do - and yes, as it turned out, it was possible. Contrary to sudoku, I could not solely focus on the hardest puzzles since there were many of them I would probably never have been able to solve. I picked puzzles somewhat randomly, made tons of mistakes despite my slow pace, and ended up with what was (I guess) my worst result at a WPC, but that was to be expected.</div>
<div style="text-align: justify;">
On the other hand, the team rounds went just fine; of course we did not do anything great in terms of score but we all had a really good time. I even got an occasion to shine with my one-man solving of the Double Block in round 16... on which we brilliantly managed to swap two "3" stickers, awarding us with 0 point.</div>
<div style="text-align: justify;">
<br /></div>
<div style="text-align: justify;">
Regarding the overall results, <b>Endo Ken</b> was first after the preliminary rounds with a solid lead on <b>Ulrich Voigt</b> and <b>Palmer Mebane</b>. And by "solid", I mean that he crushed the competition until this point; it was really impressive. Unfortunately for him the finals can bring their share of surprises, and the very first puzzle (<i>Coded Nurikabe</i>) got him stuck for more than enough time for Ulrich and Palmer to get past him. In the end, it was yet another crowning for Ulrich, followed by Palmer and Ken, with <b>Philipp Weiß</b> as a somewhat unexpected number 4. Congrats to the four of them.</div>
<div style="text-align: justify;">
Also, a special mention to our own <b>Olivier Garçonnet</b> who made it to the under 18 play-offs and got himself a bronze medal. Way to go!</div>
<div style="text-align: justify;">
<br /></div>
<div style="text-align: justify;">
Now for a few words about the championships from a broader perspective.</div>
<div style="text-align: justify;">
<br /></div>
<h4 style="text-align: justify;">
Organisation</h4>
<div style="text-align: justify;">
To say things as they are, I am having a hard time finding something that did not go as smoothly as possible. <b>Zuzana Hromcová</b> did a terrific job as the head of the organising team. The army of volunteers were prompt and efficient, marking was done in a very reasonable amount of time and for the first time, online results were available as the competition was going. I know that was appreciated by people who followed the WSPC. Queries were treated efficiently by <b>Peter Hudák</b> and the group of judges and was there some urgent matter to discuss, it was fairly easy finding someone of the organizing team. Also, I should mention that each and every volunteer was not only efficient but friendly and doing their best to help when needed, which is to be saluted. Hats off!</div>
<div style="text-align: justify;">
</div>
<h4 style="text-align: justify;">
Puzzles</h4>
<div style="text-align: justify;">
For having solved quite an amount of slovak sudokus and puzzles (although not that many in the past two years), I thought I had a good idea of what to expect, i.e. a good variety of rather easy puzzles, nicely made and with quite a lot of original ideas but rarely striking in design. Well, I was completely caught off guard by what <b>Matúš Demiger</b> and his co-authors had done. I was absolutely not expecting a round such as the "Basics" one, and several sudokus had me surprised by the thought that had gone into making them. They were still mostly on the easy side but, regarding their quality, definitely on par with what had been done the previous years.</div>
<div style="text-align: justify;">
<br /></div>
<h4 style="text-align: justify;">
Additional thoughts</h4>
There were several innovations this year; one of them being that tons of additional awards/prizes were given during the ending ceremonies. There was one for guessing who would end at the 11th in sudoku and 25th place in puzzles, one for the worst writer (won by my teammate Olivier Garçonnet, who looks like he will be a great successor to Timothy Doyle in this category), and many more. All in all, it was funny and made the ceremonies more light-hearted than usual, which I enjoyed. <br />
On the evening, some more events were organized such as a "Pyjama Sudoku Contest" and a Team Competition. I did not take part in many of them unfortunately, since I was trying to get all the rest I could to make my arm better; but the echoes I had were all positive.<br />
<div style="text-align: justify;">
Another thing the slovak team added was team play-offs. Well that was, in my opinion, the best part of the competition. It was really, really good and from a player perspective I dearly wish we will see some more of these. The puzzles were nice, the difficulty was spot-on, and there was just enough tactical planning involved to make things exciting while still consecrating the best sudoku-solving team. Also, it was much less stressful than the individual play-offs where you know you have only yourself to rely on and cannot afford a single mistake. I am glad I stayed in the A-team so that I could take part in this.</div>
<div style="text-align: justify;">
<br /></div>
<div style="text-align: justify;">
I could go along but that's enough typing for today. I will complete this or post another message if I find some more matter to discuss tomorrow.</div>
<div style="text-align: justify;">
</div>
<div style="text-align: justify;">
<br /></div>
<div style="text-align: justify;">

<br />
A week. One full week of puzzle solving. And once again, it is as if it ended before it even started.</div>
<div style="text-align: justify;">
<br /></div>
<div style="text-align: justify;">
From the 16th to the 23rd of october, more than 300 puzzle and sudoku enthusiasts gathered in Senec, Slovakia, for the 11th World Sudoku Championship and the 25th World Puzzle Championship. Most of them I already knew, and most of them I had not seen in a year - same old recipe since 2011 and my first participation. But unlike the previous editions, there was a tiny difference this year: I had injured my right forearm just one day prior to my venue, and it looked quite bad as it was far from certain I would even be able to play.</div>
<div style="text-align: justify;">
After having done my best to use my arm as little as possible during sunday, I went to bed with very few expectations since my state hadn't changed a bit between morning and evening. On monday morning things were slightly better though, and I was able to hold a pen but at the condition that I would stop every couple minutes at most to let my arm rest, and so on. I did what I could, but after the first couple rounds it was clear that this was not the year Tiit and pals would have to worry about me.</div>
<div style="text-align: justify;">
<br /></div>
<div style="text-align: justify;">
That being said, I was still able to play. The situation being what it was, I decided to focus on harder sudokus to minimize the writing I had to do, and to use as little pencil marks as possible. My playstyle, if I may say so, has always consisted in making as little use of pencil marks as possible, so it wasn't really a big deal - and since I prefer harder sudokus... well, you get the idea. The difference was much more noticeable on the sprint rounds (of which there were quite a few, unfortunately) than on the longer ones where I managed to perform honorably. The second day went about the same way as the first one, not great but good enough that I would still be able to bring some points to the team, my primary focus.</div>
<div style="text-align: justify;">
<br /></div>
<div style="text-align: justify;">
</div>
<div style="text-align: justify;">
I would not have bet a cent on it but as it appeared when the results were published, I had (barely) managed to make it into the top 10 and, more importantly, we were standing at the fourth place as a team - which meant I would soon have to take part in two play-offs.</div>
<div style="text-align: justify;">
<br /></div>
<div style="text-align: justify;">
The individual finals went as expected. Ahead of me were <b>Qiu Yanzhe</b> (China) and <b>Hideaki Jo</b> (Japan), and I was to start right before <b>Jakub Hrazdira</b> (Czech Republic). I knew I had very little chance to catch up with the first two in my current state, and indeed Hideaki was the one to make his way to the second round. Despite messing up royally on a <i>Palindrome Sudoku</i>, erasing it again and again (which my arm did not thank me for), I still managed to finish second from the round, hence ending at the 8th place. More than satisfying, since 48 hours ago I was considering resigning from my A-team spot!</div>
<div style="text-align: justify;">
<br /></div>
<div style="text-align: justify;">
In the end, and despite <b>Jakub Ondroušek</b> having been very impressive during the rounds, <b>Tiit Vunk</b> clinched victory and earned a long-time deserved world title. Jakub got Silver and, unsurprisingly, <b>Kota Morinishi</b> completed the podium.</div>
<div style="text-align: justify;">
<br /></div>
<div style="text-align: justify;">
Meanwhile, <b>Qiu Yanzhe</b> had had his revenge by taking the crown in the under 18 category, with <b>Chen Shiyu</b> earning Silver and <b>Sun Cheran</b> Bronze. The finals were extremely tensed and it was obvious that all five contestants were doing their absolute best, so I believe <b>Hu Yuxuan</b> (4th) and <b>Dai Tantan</b> (5th) deserve congratulations as well. The Chinese team did shine bright this year, as well in results as in their attitude.</div>
<div style="text-align: justify;">
<br /></div>
<div style="text-align: justify;">
The over 50 category saw <b>Zoran Tanasic</b> (Serbia) crush the finals despite starting in third place, and beating <b>Mark Goodliffe</b> (United Kingdom) who had been easily dominating the competition up to this point. Third was <b>Taro Arimatsu</b> from Japan.</div>
<div style="text-align: justify;">
<br /></div>
<div style="text-align: justify;">
Then came the time of the team play-offs. There was Japan, there was China, there was Czech Republic... and then there was us, France! There was no wonder we were overmatched (after the preliminary rounds we were standing at a modest 17k when the other teams were over 20k), but at least we had made it to the finals and we didn't have anything to lose. The format of the finals was a <i>Weakest Link</i>, meaning all four members of each team would have to solve two puzzles individually before they would be allowed to the team table and given a fifth of a Samurai Sudoku (the fifth - central - puzzle would be waiting for us on the table). There, our task was to reconstitute the Samurai and solve the whole puzzle. There was strategy involved, as it was necessary that the four players would reach the team table at some point in order to complete the Samurai; hence Timothy and I were given the - supposedly - hardest sets, which included a <i>Little Killer Sudoku</i> and a <i>Fortress Sudoku</i>, so that Yannick and Olivier would have an easier time going through their own sudokus and we would all meet at the table at around the same time.<br />
<br />
<div class="separator" style="clear: both; text-align: center;">

</div>
<div style="text-align: justify;">
<br />
Things didn't go exactly as planned but eventually the four of us were standing around the table, struggling a bit to build the Samurai, until we finally figured the correct layout. We went on a rush to solve what was left of the puzzles... then got interrupted by applauses as team <b>Japan</b> had completed theirs and taken the third place. <b>Czech Republic</b> earned the gold, and <b>China</b> was a good second.</div>
<div style="text-align: justify;">
Fourth once again, but with nothing to be ashamed of. All three of our opponents had a fantastic team composition (all four players of China-A were in the top 12!), and considering we started with a 5 minutes handicap on team Japan and would have needed about 2 to 3 more minutes to finish the Samurai... well, between 20:30 and 21:30 on the 18th of october 2016, we were actually faster than team Japan. Well worth the trip to Slovakia!</div>

The rules of <i>Sudoku 6 Parmi 9</i> come from my fellow french player and author Sylvain Caudmont. They are a great twist to the original sudoku rules and allow the creation of really tough 6x6 puzzles. This one in particular isn't devilish but should still keep you busy for a little while, although there are ways to get around the intended path.</div>
<br />
<br />
<div style="text-align: center;">
<b>Règles :</b></div>
<div style="text-align: center;">
<div style="text-align: center;">
La grille comporte 6 chiffres différents à déterminer entre 1 et 9.<br />
Chaque ligne, colonne et région doivent contenir les chiffres en question.<br />De
plus, le nombre en haut à gauche d'une zone délimitée correspond au produit des chiffres de cette zone. <br />
<br /></div>
<div style="text-align: center;">
°°°°°°°°°°°°°°°°°°°°</div>
<div style="text-align: center;">
Use a set of 6 different digits amongst 1, 2, 3, 4, 5, 6, 7, 8 and 9.<br />
Each row, column and region must contain the digits of the set.<br />The
value on the top-left corner of a bounded area is equal to the product of
this area's digits.</div>

Medium-hard sudoku this week; again, this <i>Pointing Evens Sudoku</i> comes from the French Selections 2016. Considering it was the least solved sudoku variant on the whole event, it may have been a little underestimated. What do you think?</div>

Two puzzles this week, to make up for last wednesday's hiatus. The Diagonal Sudoku (round 1) is reasonably easy, the Sum Skyscraper (round 3)... not so much. This last one was the hardest puzzle I contributed to the French selections, only beaten by Timothy's Little Killer Sudoku. Both ended up being correctly solved by only three people, so good luck trying to make your way into it.</div>

Hello there. I know it has been a while, but the break I took since last december was much needed. I can't get back to publishing a weekly puzzle yet, but I will try to post something once in a while; and despite what I just said, I am actually going to publish a puzzle a week for a few weeks since the French Selections for the WSC happened just two weeks ago and I have some brand new puzzles to share.</div>
<div style="text-align: justify;">
I hope you will enjoy them. Have fun playing, and good luck.</div>
<br />

Just like last year, this year's World Puzzle Championship featured an instructionless round (on which I did poorly, but nothing new here). What better occasion to publish another "On your own" puzzle, after <a href="http://enigm-attic.blogspot.fr/2014/08/grille-de-la-semaine-97-et-9e.html" target="_blank">the one I made back from WPC 2014</a>? The rules of this one are supposed to be simpler to figure out, though the puzzle itself might not be that easy. Good luck, and enjoy.<br />

As my 100th puzzle (though I find it hard to believe) contributed to the Daily League, here comes a little something that should keep you occupied until I find the time to redact my thoughts about the 10th World Sudoku Championship and 24th World Puzzle Championship.</div>
<div style="text-align: justify;">
It has been a while since I made a Little Killer Sudoku, though this variant matters much to me. <a href="http://enigm-attic.blogspot.fr/2013/09/grille-de-la-semaine-47-league-of.html" target="_blank">This particular puzzle</a> garnered quite a lot of positive reactions from renowned authors, which felt immensely rewarding at the time. Regarding Killer Sudoku, this variant and I have always been in some kind of love/hate relationship. I enjoy solving Killer Sudoku, consider myself reasonably good at it... and always fail miserably when I encounter one during a competition.</div>
<div style="text-align: justify;">
Combining these two variants felt like a good way to celebrate this milestone. As usual, the puzzle can be solved using a series of purely logical steps, without ever needing guesswork. It is hard, though. You have been warned...</div>
<div style="text-align: justify;">
<br /></div>
<div style="text-align: justify;">
Good luck finding the keys of this Little Killer² Sudoku!</div>

<b>Règles :</b></div>
<div style="text-align: center;">
Chaque ligne, colonne et région doivent contenir les chiffres de 1 à 9.<br />
Les indices à l'extérieur de la grille correspondent à la somme des chiffres dans la diagonale indiquée. <br />
De plus, le nombre en haut à gauche d'une zone délimitée correspond à la
somme des chiffres de cette zone. Un chiffre ne peut se répéter au sein
d'une zone.</div>

<div style="text-align: center;">
Each row, column and region must contain the digits from 1 to 9.<br />
Clues outside the grid represent the sum of digits in the indicated direction. <br />
The
value on the top-left corner of a bounded area is equal to the sum of
this area's digits. No digit can repeat within an area. </div>
