Lösungscode: Enter the digits in the 1st, 4th and 7th rows (left to right).
For each red cell enter the smallest digit first, then the larger digit.
For each black cell enter the digit 0. (That is, 27 digits in total)

Thanks Dina, I'm pleased you found it an amusing solve :-)

Funny theme and quite challenging, thanks!

I really liked the concept!

@Voyager Thanks for persevering with it. Very well done in succeeding with a logical solution, and I'm pleased to hear that it was a helpful experience! :-)

@SudokuExplorer: I finally found a pure logical path; so this puzzle helped me to regain some logical strength. Thanks for this puzzle!

There is also a logical path without seeing this a priori...
But he can't read the hidden comment until he has solved it. If he writes a hidden comment himself, you can edit it and he can read it.

@Voyager There is a trick which makes it easier. See my future hidden comment for a hint.

@voyager: I remember there was a straight logical way. Some tricky steps, but not too hard. It deserves more solvers.

Sadly my logic is not good enough to solve this puzzle - I tried it twice; but I already had a lot of fun with the title!

Btw I totally agree that there is no point in having 5 or so killer sudoku tags. They should somehow combine them into one tag, which everyone should then start using.

But that's strange: If you click on the written label, you find all the old toroidal puzzles. I'm sure they had the picture label...
am 21. September 2020, 21:03 Uhr von Dandelo
Or there was a problem with the server, maybe the picture was not readable.

Rotstein's puzzles also have two toroidal labels ...
Probably someone tries to clean up the labels. We don't need 5 Killersudoku labels, or 2 toroidal labels. You should use the pictures if possible. Don't start a new label, when it already exists.

The picture label has existed for as long as I have used this portal. Also the written toroidal tag has not been deleted.
Maybe they changed the icon to automatically include the written tag (which links to more puzzles than the icon does).

Maybe you have written "toroidal" (he too) and someone has corrected the mistake by deleting the text label and adding the picture label?

@Dandelo It also happened to Rotstein's puzzles...
I initially added the icon when I created the puzzle, but the icon disappeared today.
Now that I only added the disappeared icon again, a written tag has also appeared. That's strange...
am 21. September 2020, 20:44 Uhr von Dandelo
I think it hasn't disappeared. Now you have it twice. Maybe you've forgotten that it is a picture?
am 21. September 2020, 19:20 Uhr von SudokuExplorer
Can anyone explain why the toroidal tag just randomly disappeared from all the puzzles? Was there a recent update to the portal?
If they wanted to get rid of tags, they might as well have got rid of all multiple tags such as for killer sudokus.

Thanks, I'm glad you had a great TimE!
It was my first time trying to make a non-sudoku puzzle. There was a little bit more number theory behind the scenes (just like the toroidal anti-queen sudokus, see the second bonus puzzle of the 7x7 sudoku).

Cool variant! Like a sudoku but more interesting.
am 10. September 2020, 22:38 Uhr von SudokuExplorer
@Dandelo Thanks for giving it a go, even though you're not a fan of latin squares. I'm glad you still enjoyed the break-in and the solution path. :-)
am 10. September 2020, 22:19 Uhr von Dandelo
Nice puzzle, nice break-in, nice solving path, but definitely not my favourite puzzle type.
