When I was little, after completing a painful test, my mother used to tell me "Don't worry, if it is hard for you, then it is hard for everyone" :)

First, I want to say that all these points that have been criticized were our personal choice, we wanted to do something different, but it was not appreciated. I'm sorry for that. I have been preparing puzzles for many years and I've often tried to make some innovative efforts in order to enrich the puzzle culture. These different efforts are generally criticized at first, but some of them are eventually accepted.

Months before, when the date of our GP was set, I had already made my mind that it would be something different and I mentioned those to Deb. So the types were selected according to that. We could build the set with many familiar types that everyone would be satisfied, but we chose not to.

About the fonts: Our starting point was the "check the puzzles" round in WSC 2011. Sudokus were built with many different fonts and the purpose was to challenge the visual perception. We used different fonts in classic Sudokus, based on this purpose. There are two points of view here: Solver's point of view and designer's point of view. The solver dislikes any feature that makes solving harder for them. The designer wants to do something different. That round in WSC 2011 was hard for me, I'm not a good solver and those fonts made everyting harder. I did not like that round as a solver. But when I put on my designer hat, I think it's a great idea. So in this test, we thought as a designer and personally I don't regret this choice.

Overall, in this test, there were many features that were deliberately put in order to deform the usual structure. I suppose too many of them came together and that caused so many reactions. Maybe we should not put them altogether, we're sorry for that.

Thanks for your comments,

Serkan

I agree with most of the criticisms that have been said here but at the same time I want to support Serkan, proven innovator in the world of logic. I suppose he and his team member Salih wanted to bring something new again. Good job!

I'm doing fine in logic sudoku variants. When I saw different fonts in first few grids, I thought the whole test is with such crazy fonts. I told myself, "get used to it!" Once I came out of the classics, the font has become normal . Then I quickly flew to see the point distribution and decided to solve in order, as usual. I am personally very happy that I was able to solve snapshot sudoku in the last 10 minutes of the test, which is not in my case with such tricky puzzles. Last week I failed on duello. Zero was completely out of my mind and author's obvious intention was not to show it in the example. The question for discussion is should samples clearly demonstrate all aspects of the rules of the puzzle? Of course, this reduces the author's maneuver for surprising factor, but I think there is still a lot of "legal" ways for good surprise.

And it seems we have 7 different GP winners. That will be a great final round in Beijing!

Hi Serkan, thank you for your explanation.
I really love Turkish-style puzzles (WPC 2009 was the best WPC ever) and they are still the best from my view. I had no problem with the non-sudoku logic sudokus, but I was really dissapointed when I saw the unusual classics. I asked to myself: "What a hell, why Serkan made such a madness? Is it a shot into a dark, just to catch attention? I do not understand." This moment surprised me so much, that I was not able to continue solving. Before then I have solved some harded puzzles (maybe three and skipped "unsolvable" snapshot sudoku) and consider them very nice, however I have no motivation to continue competing.
Another thing is the huge puzzle booklet. As I complain before (atfer Fugitive Warrant), I still think, that 21 pages are so much for a contest, that wants to invite new competitors. To save some papers and nerves I printed 2 pages per sheet, but some numbers were too small. Please, don´t think that I am looking for another complaints, but I have always dilemma how to deal with such a puzzle booklet.

Thank you for a nice contest, great puzzles (also prefer the term "puzzles") and also valuable experiences :)

Personally loved it (except for the hard to read numbers on the early grids) though I can't argue with those who felt it was as much puzzle as sudoku.

I agree with this point mainly. Each twist on its own would've been only a "little twist" that some liked and some didn't while all together, there was some different thing each individual didn't like which stayed in mind even if they liked the rest. You gave the WSC example, and the point value there was very less compared to the rest of the WSC.

I also agree with, and like the idea of enriching the Sudoku/Puzzle culture. Any new idea/innovative test will always be a risk once provided to the large audience, especially in a test-series trying to get new competitors in. So I respect the fact that you take these risks, and I can understand how bad it must feel when you take a risk and it's not well received. Once again, from my own perspective, thank you and the other authors for a fun test :)

Interesting test. I liked the logic/puzzling emphasis that gave it a fresh feel. I'll echo other commenters that a points summary would have been nice and the change in fonts was distracting.

I like the A or B puzzle type; this particular one was probably overrated for points.
I didn't get to the Bands or Blocks (#20 and #21) during the time limit but enjoyed both of them post test, particularly the Blocks.

GP7 is over. Password removed from Sudoku booklet. Here is the link to solution booklet.

The score page will be public in a while.

I hadn't realized the way to avoid the contradiction that I found during the test on the snapshot! So it's good that finally I learn this idea. I was too fixed in my thinking. That was a very clever twist. I agree with the commenter who suggested that having one twist like that in a test is a nice spice, but having many such twists may just overload us, especially if we're expecting zero twists going in.

I enjoyed the test, though I felt it was overall too hard/long. For me it felt unsatisfying to only solve 7 of 21 puzzles during the test, even if I did spend my time trying to solve the higher point value ones for the most part. I certainly look forward to spending some time on the remaining puzzles later! There is a lot of beauty to be found in these puzzles; none of them are boring, that's for sure!

I enjoyed the puzzles tho' for many of the reasons mentioned above (as well as being sick), I got bogged down and did not submit any answers.
I did not figure out the snapshot puzzle trick (would not have considered that within the description) and have wasted way too much time on it in interim! Glad to learn what I did wrong. Will have to look again. Tho' if rotation is allowed, then that opens up so many more possibilities that I probably wouldn't even have attempted it during the test.
Did manage to solve most of the others by the end of the day.
Good job. Thanks for the effort

Actually, if I understand it correctly, the 6-9 snapshot is the only one that can be rotated because the numbers still stay valid upon rotation.

Results are now public.

I do not like this snapshot twist at all. It was not mentioned that snapshots can be rotated. I spent much time to verify that something wrong in my logic and lost time. Those hidden tricks should not be allowed on that level of competion.

On another note, it will be nice to have standartized fonts.

Overall, the test was really nice. Thanks to authors and administrators.

Congratulations to Hideaki, Daisuke and Bastien for having the top three positions.
The grand prix format let more solvers participate to online competitions. I am a loyal solver of them and this was my first one as an author. Thanks to Deb and LMI for the organization of the test, and also thanks to all participants of the test.
I would like to express my extra thanks to the nine solvers who solved the snapshot sudoku. I was sure that I will receive some bad comments for that sudoku. Serkan came with the idea of rotating of a snapshot with a single digit at a corner. I applied the idea using two digits, assuming this will make it much obvious. Apparently, it didn’t work as I expected. I hope this twist will not cause any discourage for sudoku solvers.

I have two main complaints. One being that there simply wasn't enough time to dig into these puzzles. I don't mind that they were hard and I quite enjoyed completing them after the contest was over. (Except for Snapshot Sudoku that either has an error in the setup of the puzzle or I just can't figure out how to do it.) My other complaint is that the example puzzles in the instruction booklet were often smaller puzzles than the puzzles presented in the contest. Since a lot of these puzzles were novel to me, I didn't get enough practice with the smaller versions to feel prepared for the full-size puzzles in the contest.

See the earlier posts for discussion on this. :)

Also, Instruction booklets aren't given for the sake of practice but to understand the rules. For practice, if you are unsure of where to go for a particular type, just post on the topic before the test starts, and someone will give you some links.
