Pair up Sudoku - the door number
(Published on 26. February 2021, 04:45 by bigger)
The idea comes from Easter puzzle.
Standard sudoku rules applies. Fill the grid with numbers from 1 to 9 so each digit occurs exactly once in every row, column and 3x3 box.
If the digit outside the grid is n, and the first digit it sees is x and the second y, row x column y would be n.
This puzzle is made by Old Miles from China shortly after SirWoezel one. It's probably the first idea Old Miles took from here. And it's probably the first puzzle that make us interested in here. I kind of forgot this because it's made way too long ago and I wasn't a fan of this type(which made it a four star annoying) But recently theGreatWizard's puzzle remind me of this one. As the idea was taken from here, it's only fair if I give it back. It's the last puzzle for the valentine month. So happy Valentine.
Solution code: Row 5 column 5

es sind wirklich genug Ziffern vorhanden, um einen guten Beginn zu finden. 3 Sterne wären angemessen.

nice. thanks. wouldn't rate it 4 * - enough digits are given in position 1 or 2 from the border of the grid to get a smooth start.
It did not annoy me at all. I encourage setters who are trying to come up with novel ideas, even when some are not a direct hit. One can not claim O.M. isn't trying to please.
Bigger: welk, that's up to you guys. I think this type is annoying. It's not that productive doing that much observation for one digits. So i put it in the four star, the annoyed me ones. It definitely annoyed some of us too. The overloaded clues.
