For Kropki Sudoku, does the reverse rule also apply? That is, if there is no white/black dot between 2 cells, does it mean that the numbers are neither consecutive nor half/double of the other?

Yes.

I'm unable to solve the Kropki Sudoku. When will the solutions be available?

Solutions will be available only after the test. Check your inbox for solution to this one.

I'm glad that you know D means disqualified.
But do you really not know why you are disqualified ?

Thanks a lot for your reply. I am really not aware of the submission process and that is the sole reason of my post. Once given the proper direction, will submit in the shortest span of time. ;)

In case you've misunderstood the point of these contests, it isn't to just submit answers you already know quickly. You're supposed to actually solve the Sudokus manually. and logically, for the first time once the timer starts. Not just go on making new profiles and submitting answers you already know. Not sure why this needs to be explained, but now that it is, please solve in the spirit of competition like everyone else does. Its for your own "solving" enjoyment, we're not giving out trophies here.

I think you have misunderstood my query and that is the reason you have played with your words in an offensive way. Being rejected all the time, I tried submitting through different names. I have actually solved the puzzles manually and that is the reason I was trying to enlist my name. Anyways, I have understood why I was disqualified and let me clarify with you as well because I feel you do not know the reason yourself. The reason of my disqualification is that I was submitting the paper and the online mode simultaneously. I feel pity for you for not having the appropriate answer. I have nothing to say but to wish you best of luck as a support administrator. hahahaha.....

I am not sure what is not clear in Prasanna's post above, but I will get it straight now. You were disqualified in December as well (for which you didn't protest). Here is the snapshot of your submission details from December test.



I don't know what others read from this table, but I read it as "it is not possible to solve 4 classics sudokus in 216 seconds, in a fair way. More so, about solving 3 variants in 135 seconds. And apart from solving, this time also includes time to get the password, print it in a printer, and entering the answer keys". Refer to the archive page for December for timings of world's best sudoku players.

Please note the word "fair" there. And we have every right to disqualify players, if we think they are not playing fair.

Once a player is disqualified, they will remain so until we manually change it back. That was the reason you got disqualified in Feb. In any case, I have enough reasons to believe that your Feb timings are not fair as well.

Passwords removed and solutions appended to the puzzle booklets.

I clearly don't know how to play the No Knight Step in this beginner's test. Still a lot of fun!

Some time along the solve noting that 7 in box 1 can only be at R3C3 was the key for me.
The Roman on the other hand was much harder - at least it seems so from the score page so far.

Same here. That one took more than than the Roman.

The Classic 3 was really beautiful and adequate difficulty.
Must be a masterpiece!!

Passwords removed and solutions appended.

Classic 3 was truly a master piece.

Thank you! I think making this sudoku was a rarely coincidence.

Thanks to all participants and congrats to top beginners, as well to the fastest experienced solvers!

Can someone please explain how to solve Roman Sudoku.
I didn't get this part.... "Some
cells are either
partially or fully
filled, and it is part
of solving to
determine the cells
that need to be
added to."
How can you determine which of them are fully filled ??

That's part of the solve. Say you have a cell with "III". Now III can either stay III which is 3 or the only element that can be added is a V to make it VIII which is 8. So III will be either 3/8. Similarly a cell with "V" has to be 4/5/6/7/8. An "X" has to become a "IX" which is 9, a "I" can never become a 5. These things and other such limitations are used to determine where an element can be added to make the correct digit.
