Herringbone
(Published on 26. October 2021, 18:02 by Qodec)
- Normal sudoku rules apply: Each row, column, and region indicated by thick borders in the grid must contain the digits 1 to 9 once each.
- Thermometers: Grey paths with circles indicate thermometers. The digit in the bulb (circle) is smaller than the digit in the tip.
- Palindromes: Grey paths without circles indicate palindromes. The digits in both tips are equal.
- Killer cages: An area surrounded by a dashed line is a 'killer cage'. Digits in a cage sum to the number in the upper left corner.

Solution code: Row 5 and column 7. I.e. the 9 digits in row 5 from left to right, followed by the 9 digits in column 7 from top to bottom, for example: 123456789123456789

This rang very vague bells and I see it was featured on CTC, but happily I couldn't remember my solve so had the pleasure all over again of discovering this supremely elegant construction.

Wow, what a puzzle!
I absolutely loved the break-in, which I solved without hurting a set. But the second break-in was much more difficult for me. Over 2 1/2 hours! Thanks for the brain twist.
I loved the 5 cage, when I discovered its effects.
The 20 cage was my nemesis, took me forever to figure this one out.

This is one of my favorite puzzles I have solved of yours, and I was already a huge fan of your puzzles. This had some really fun logic that I don't recall having to use in other puzzles that made it a joy to solve.

Thanks for the tips, SudokuExplorer. I have definitely already solved Mitchell's puzzle, and the one from Sonic was on my radar at least.

The break-in was well-telegraphed and the difficulty remained consistent. Thanks for the lovely puzzle! :-)

This had some really elegant, new (to me) logic. And so much fun!

I was slightly perplexed at the beginning, but once I understood the setup, it was not actually that hard to solve. Very satisfying, especially since it is a first of your puzzles I managed to solve. Thanks.
