On the Straightened Arrow
(Eingestellt am 6. Februar 2025, 19:50 Uhr von marty_sears)
- Normal sudoku rules apply.
- Yin Yang Yong: Colour the grid red, yellow and blue, so that all cells of the same colour are orthogonally connected, and no 2x2 area is fully one colour.
- A red cell's value = double its digit.
- A yellow cell's value = its digit.
- A blue cell's value = half its digit.
- Straightened little killers: Clues outside the grid give the total value of the indicated row or column.
- Equal value lines: A blue line joins two cells with the same value.
Rules:
Please leave a comment if you enjoy :)
Lösungscode: Row 6 from left to right

I loved this puzzle, didn't know how to approach it for quite a long time. And then it clicked. After that the flow was wonderful, it always guided you to the next deduction in line.
Hopefully there'll be a CtC video of this. I'd love to see Simons' thought process on this. I needed an excel table, where I could play with double/single/half-digits and their sum. Doing this in my head alone, no way! My brain would probably melt ;-)
Thanks Marty for another great 6 hours of my life (and I mean that with all seriousness)
Marty: thankyou, and you're in luck! This was featured on CTC last Sunday :)
DonQuichopp: Oh, great, thanks! didn't search for it yet :-) looking forward to watching it.

Extraordinary puzzle! Quite straightforward when you get a feel of it but otherwise not that easy to begin with. After solving it leaves a great feeling of accomplishment. Thanks Marty for setting it!

Harder than 3 for me, but probably due to me not really doing 3 color yin yang before

Almost felt like a fog of war puzzle (in a great way) with how piecemeal the logic was - there was always one single clear place to look, and the whole thing came together one step at a time quite nicely!

Wonderful puzzle. Tricky arithmetic made my head hurt. ;-)
One of these puzzles that seem impossible, but there's always (exactly) one thing that brings you a step further.

This was a brutal introduction to three-colour yin yang, for me who didn't even do that many yin yangs to begin with, but after investigating its dynamic, it became manageable and I definitely came out of it knowing and understanding more about YYY. Thank you for this beautiful puzzle!

The elegance of the path is a japanese garden worthy. Brilliant.

Amazing and entertaining puzzle! Thank you very much for creating and sharing another beauty. (To the best of my knowledge the idea of Yin Yang Yo/ung goes back to at least 1998, when such a puzzle was made for the WPC.)

What a brilliant puzzle! How do you even come up with such things? :)

Silverscree - I made one a while ago. Don't know whether Marty or I had the idea first but mine came out as "Yung" instead, ha ha.

Marty: yes I definitely didn't come up with the idea of 3-colour yin yang, definitely there were several examples before mine. But I do enjoy setting them, probably more than normal yin yangs

I finally solved a Marty Sears puzzle! And all on my own, ha ha!

I've always loved three-colour yin yang (I also have always secretly added a yong to the rule in my mind) and this one doesn't disappoint. Thanks Marty :)

Bloody lovely.
