Sudoku Variants Series (317) - Sudoku Pair Up

(Published on 20. April 2021, 20:07 by Richard)

For this Sudoku Variants Project I have planned to publish a different Sudoku variant every week. I will see how long it takes before I am running out of ideas.

Sudoku Pair Up
Apply classic sudoku rules.
The digit in a cell with an arrow is N. The sum of the Nth digit in the direction of the arrow and that digit N is always 10. Not all possible arrows are given.

Inspiration for this type comes from Old Miles.

Solve online in Penpa+ Thanks to henrypijames.

Solution code: Row 6, followed by column 3.

@bigger:
The number of published puzzles here in the portal has exploded. If you click on the button Statistics on the left of the screen, you see how things developed. With such a vast amount of daily new puzzles, most solvers have to make drastic choices regarding the puzzles they want to try since there are simply too many too handle.

The number of solves on my own puzzles is more or less the same as it has been throughout the years, although the number of active solvers has sevenfolded. So relatively, my puzzles don't seem that popular too.

I understand that you have a strange feeling seeing your idea in another form at another moment. I generalized it, resulting in a type that has potential to be used in competitions or championships.

The list of possible types and ideas will end one day, although I have seen enough interesting ideas here in the portal to keep going SVS for a while. If you are interested in the previous 316 episodes of SVS, simply scroll through the list. They are all still available here in the portal. You can tell Old Miles that he is a wonderful constructor with sparkling ideas who has obviously made a lot of very nice sudokus! :-)

A lot of puzzles I post, if not mentioned published in 2017, has some of my idea. Recently, Old Miles and I are kind of running out of ideas. I would really be appreciated if you can give me some variant suggestion.
This particular idea, pair up, comes up because of valentine. In other words, it's a holiday special. I try to make people feel the feeling of how people pair up around me while I'm still lonely. So for me, seeing the idea with a certain background story again after the love month is really strange. It's like eating turkey after Thanksgiving or eat the bread without the crust. Another thing is your idea get triple the solves of mine. I just don't know how to tell Old Miles about this.

@Bigger: I can only speak for myself. I do solve puzzles from other players, but sometimes I forget to enter the solution code. In the last months I have been extremely busy with my job as well as with other puzzzle related things. (I am board member of the Dutch puzzle association and have many tasks coming from that too.) Currently I have a small pile of solved puzzles of which I have to enter the code.

As for expectations: I don't have any. I just noticed that you have posted some interesting puzzles either made by Old Miles or other authors. If I think a type is suitable for SVS, I make an example of it, post it here and provide a link to where my inspiration comes from. That's all there is to it.

O That's interesting. So you guys actually check the puzzles but didn't solve the puzzles. My only problem is that it's a two month old puzzle. You are kind of telling me that the puzzles I post recently weren't that good as they're used to be. So what kind of variant do you expect from me?

Really nice concept there! I had a lot of fun solving it.

Like usual, guessing is not necessary in this puzzle!
Although the overall difficulty of this puzzle is not that high, there are (at least) two very nice intrinsic logic steps that you have to make to avoid guessing. I have written those as a hidden comment in case you didn't find them (both) for learning purposes.

Well, my logic skills ran dry and I had to take a guess. Apparently it was the right one because it led unstoppably to the finish.

@Big Tiger: I have written two crucial logic steps as a hidden comment for learning purposes.

That was wonderful solve path.

@cdwg2000 thankyou

@wrightbr3

The arrow cell is the number 1, then the next cell is 9, and the arrow cell is the number 2, then the next two cells are 8, and so on.

Doing a lot of Stephane's various pointing sudokus has prepared me well for this one. Still managed to make a dumb and banal mistake (misreading my own pencilmark) repeatedly and had to restart several times.
