I realized why you are not able to see the score page.
Goto the test page. Click on "Start Fivefold", after that go to the the score page.

I've read all the rules in the first page.

You are not alone. There are 2/3 players who did similar mistake.

it was a great set of puzzles. i had actually thought of doing well before the test . but for the first 10 miutes app. i was still collecting the printouts (courtesy - my printer). and with 70 minutes gone i had done only 4 low pointers and also got the killer wrong . i knew i had goofed up big time. spending the last 50 minutes was terrible with my group sum going wrong. it was a test where i did more wrong than right. but it was a wonderful test

Really great puzzles. It would have been even better had I not dropped almost 200 points because I messed up the cleanup phase of three puzzles *sigh*.

Congratulations on another test well done, Serkan.
Wow. You make good sudokus!
Looking forward to see a lot more exciting tests from you :)

This test was a failure.
Not the test itself of course, just my own performance. As Jan said, the global difficulty was very well estimated. It is just too bad I did a big bunch of big mistakes, in particular during the second hour (the detailed results are very telling). Really too bad because I wasn't in a bad shape.
Puzzles themselves were wonderful. Thanks Serkan and congratulations to the toppers for their results.

I surprised myself by solving relatively cleanly (albeit a fair bit more slowly) using the online interface (alas, no access to a printer here)... it's a bit of a shame I restarted the thermometers 4 times, but generally the puzzles were of at least as high a standard as their WSC inspirations, and there was a lot to enjoy about this test. I'm not so keen about arbitrarily docking points as time goes on, but hey, these tests are the perfect opportunity to play with quirky new scoring systems.

Great stuff!

I loved this set of puzzles. I'm not anywhere near competition standard with my sudoku solving but really enjoy having a go, and it was great to find a competition where I could do just that! One or two of the puzzles were beyond me, some were challenging (have since completed them at my leisure) and some of them were just right for the likes of me, so thanks for a very inclusive test! I made a couple of errors of judgement as regards which ones I could solve quickly, but was especially pleased at getting the full 82 points for the musketry sudoku - one good decision made!

Once again, thanks for a great set of puzzles.

Couldn't compete, but printed the puzzles and they make up one great set! Favorites: Quadruple, Number 5 Still Alive, Distance, Thermometer

And just wondering, where should you start in the double diagonal and the killer, could only get a few digits without trial and error :(

Fivefold is over. Congratulations to purifire, janoslaw, deu for topping the list.

Great set of puzzles, awesome performances from many players, and huge turnout for LMI. Thank you everyone for participating.

Too early morning for Serkan to comment (who has been mysteriously not putting any comments before / during test ), but hope to hear from him soon.

Now that the test is over, feel free to discuss how the points system affected your strategy. There were not many complaints (unlike in Twist), but we would love to hear how it turned out for you.

For the Double Diagonal, you can fill up all the 9s and then all the 1s. Post this, the Diagonal from R9C2 to R2C9 can have only 8 unique digits and the only number missing is the digit 9. Which allows 2 to be placed at R4C7 and subsequently all the 2s are also placed.. post this it becomes easy to fill the grid up.

Rishi

congrats to rishi for beating the best in the world

It was one of the greatest tests at LMI, almost all the good known variants of sudoku were there. Congrats to Rishi (purifire) for his awesome performance. And ofcourse congratulations to all those who participated.

Found out that some player first solved and submitted online. Then towards the end of the test they again submitted using paper mode - both answers being correct.
They thus lost lot of points. We'll fix the score page soon.

But there is no player in the top 40 who will gain points.

Beautiful set of Sudoku's, thoroughly enjoyed solving the test! :)

Done - The biggest gainer is luboign who moved from 79 to 56.

Players are requested again not to do this. It is waste of time and error-prone.

Great set of puzzles. For me a bit disappointing, as I got caught in a misinterpretation of the Quad Sum rules. The phrase that "numbers may repeat around the arrow", I interpreted as "there is no number larger than the number the arrow is pointing at", which meant that for instance I could not exclude the 5 in R8C6. That made the puzzle significantly more difficult, and in the end unsolvable. Cost me a lot of points :(

Congratulations Serkan for a superb test, Rishi for finishing at #1 and Rohan for finishing in Top 11 !!!

In his series of "Puzzle analysis of the week", Nikola has chosen Double Diagonal and Pandigital for this week.

I got completely stuck on the Odd-Even-Big-Small sudoku during the test - put it away after having wasted about 7-8 minutes, and tried it again this morning. Well, it was hard but I nearly reached the end. But there, I found several solutions. No mistake as it seemed, so I searched again and again, wondering what I could possibly have missed. Nothing.

Then I finally read the rules and noticed that they clearly said : "An indicator symbol on the outside says that the first two numbers along that row or column are either odd (1,3,5,7), even [...]


*kick myself*


Anyway thanks again Serkan, I had fun even on sudoku types I tend to dislike.

Hi,

First of all thanks to all participants for spending two hours :)

Congratulations to Rishi Puri, Jan Mrozowski and Hideaki Jo. All three of them took their strategies wisely and all three gained more than 700 points in the first 70 minutes. Hideaki Jo started the test with an amazing performance as he mentioned, but couldn't keep it up. Jan Mrozowski also started well, but near the end he had 3 or 4 broken puzzles. What I admired about him was that he realised and corrected 2 or 3 broken puzzles in the last few minutes. This really shows his confidence. And the winner Rishi Puri, first of all I am so happy to see a new champion. He too started very well and progressed consistently until the end. With the points 779-227-125-40 according to the four stages, he was the only one in the top three to achieve "most points in first stage, least points in last stage" theme.

I am happy that the scoring system worked out well. In my opinion, this kind of scoring shouldn't contain time bonus. Because the author is supposed to design the puzzles in a way that forces the competitor to take a strategy, and time bonus in a twist scoring like this is not so reasonable. The author must be sure of the difficulty of the set and must be sure that there is no need for time bonus. Honestly I was not so sure about the difficulty and I gave time bonus, because in the case that a few solvers completed the test, there could be an unfair scoring due to the twist structure. For example I was so sure about the TVC series, but there happened to be an unfair scoring due to lack of time bonus, so I didn't want to take a risk.

The puzzle with the highest rating was Number 5 Still Alive - 9.5
The puzzle with the lowest rating was Just One Cell - 5.71
221 people started the test and 199 of them submitted at least one answer.

Thanks again to all participants, WSC organizers, LMI, Deb Mohanty, Gulce Ozkutuk Yurekli and Salih Alan.

Best

Serkan

I also enjoyed the test a lot. Great puzzles!

I don't really think the point system has more advantages than disadvantages, but honestly I don't really care either way. One disadvantage is that there are several deadlines to watchduring the test:
I began with those puzzles I thought I was best at. Of course the high-pointers first. Then before the 70-minute deadline I solved several low-pointers. After the 70-minute deadline I began with high-pointers again. I should have done the same (switching high-pointers with low-pointers) at the 90-minute, 105-minute and 120-minute deadline, but for me that would have taken too much concentration away from the puzzles. Thus I ignored all deadlines except the 70-minute and 120-minute deadline...

Stefan

[edit:] There were a lot of forum comments from competitors while the event was still running. Comments on puzzles - how innocently they might be intended - should not be posted. Before taking the test I browse the forum thread of course. I am not happy to read which solvers had problems with which puzzles or which puzzles they were happy to have tackled. It is not easy to let oneself not be influenced in ones own choice of puzzles.

I completely agree with this. I understand it may be difficult to restrain oneself from talking about the puzzles we just solved, but it really is necessary to avoid influencing other players. To deal with this, I usually post a first message right after having completed the test, in which I usually complain about my poor performance due to many mistakes, blah blah blah, and then a second one once the test is over, in which I talk about puzzles themselves.

Please keep it in mind for the future, it will be highly appreciated... at least by Stefan and I.
