In sundoku, there are eight possible ray directions. If a ray is not marked (like in the example), does it imply that the numbers on that line CANNOT be in decreasing order.


No, it doesn't mean that ! There are no restrictions on cells where there isn't any ray, no matter if one could imagine a ray in that direction.

(The real fact is that I failed to build a 6*6 grid with an 8 rays' sun - if someone achieve this, I would be happy to see )

To be crystal clear concerning colors : colors don't have any importance, on any puzzle. They are purely decorative ; we were wishing to make this test a "festive" one, so, as Fred said, it was nearly impossible not to put some colors in...

You really need not worrying about that. You'd better worry about the puzzles themselves...!

Starting point are the 2 R's. There are only 2 ways to addition some 1-6 digits with result 18: 1+2+4+5+6 or 3+4+5+6. the consequence is that the 3 should be on first or last position, and on the opposite you have a pair 12. So you have 3 on R4C6 and R6C5, Then also on R2C4 (just classical placement). Then you can study the "E" columns where 2-3 must touch each other and 1-4 also.

I think that give a good start !

Neeraj, look at row 4.... the value of R is 18... now in a 6x6 the sum of all numbers is 21.... so number 3 is the uncommon part of the 2 way sum...
so we need 3 at one end and the numbers 1&2 at the other and 4,5,6 in between. Since 3 is already there in Col 1...R4C6 is a 3 and R4C12 has pencil marks of 1,2.

If the same Sudoku is submitted using both modes and only one of them is correct, it will be left to organizers to decide if points are to be awarded.
I think no points should be awarded in such cases as, otherwise, this system can be (mis)used to make answer guesses.


I think the best decision is to take into account the last submission, whether by one or the other mode. A player can solve on paper, submit, and then realize there is a mistake. Perhaps he choose to solve again with interface, and submit again. Or the reverse situation. Of course, if the first submission is correct and the second one not, it's a pity for the player...
So please, don't submit a false code if you had already submit the right one

That seems ideal. We'll stick to this rule (at least for this test, and revisit in the next test if required)

After reading the translation at sudokufans forum, I'm suddenly having a question about Jigsaw Wordoku.
Will the word (or letters to be used) given? Or players have to be find it as part of solving.
In the example it is clear since U is repeated in one column.

We are making an experiment - this test starts 6 hours earlier than regular LMI tests.
The scheduled end time is same as regular LMI tests timings.

Please check the exact timings in the submission page

We finally take the decision to write the word (whose letters are used in the grid) in the instructions of the puzzle. So if you want to save a few seconds, read the instructions of that puzzle before solving !

Yes, Fred, it is a challenge, but I think I succeeded!



I tried everything and it's really impossible to catch the last cell (R1C1) with the decreasing ray.

I expect a lot of suns and flowers this weekend.

Nice, Nikola ! Good Idea to shorten a Ray to achieve this. I think it's the only way, but I'm not mathematician, so I do not want to do a strict proof

Good luck for the tournament !

Good luck to all and may the best win!

Thank you very much for very nice test! Normally I cannot solve sudoku very quickly, but i tried to do my best :) I broke some puzzles, and i couldnt fix them, especially i am very sad about "mixed", i had almost finished, but i hadnt enough time for it :) In any way, i like very much, and i must say that "Killer 0-8" was amazing!

Thank you very much again,

Thank you, Serkan. I'm sure your comment will reassure Bastien, who was not very satisfied by the killer 0-8 (he's the author) and wanted to remove it from the test. Fortunately we managed to make him change his mind
