Third Order Logic
(Eingestellt am 26. Oktober 2025, 22:57 Uhr von Die Hard)
Normal sudoku rules apply. Digits on a pink renban line form a consecutive set in any order. Box borders divide blue lines into regions of equal sums. Every three digit sequence on a teal modular line consists of one digit from each of the sets (1, 4, 7), (2, 5, 8), and (3, 6, 9). A digit on one side of a black kropki dot is double the digit on the other side. Digits on an arrow sum to the digit in the attached circle.

Lösungscode: All 9 digits in row 1.

Beginner here, can anyone give me any clue at all. At least explain what third order means. Thanks
Die Hard: As has been mentioned in other comments, the puzzle title does offer a clue as to how to start the puzzle. I won't explain this further as this would give it away. Since you have noted you are a beginner, I would recommend you find some 3 and 4 star puzzles to tackle and come back to this puzzle later once you have built up your experience. I'd also recommend watching the CTC channel - you will periodically see puzzles solved that require the same solving techniquies required in this puzzle.

One of my favorites. Quite a while just staring at it looking for something--anything--to help me in. Then I saw it, and it was a beautiful and consistent solve.

Really cool puzzle. It is one you can stare at for a long time making little progress but if you see the right thing it unlocks a really interesting puzzle which has depth and uses the clues beautifully. Everything works together through the solve.

Very neat and cleverly set puzzle! It's a consistent flow till the end for me too, but I really like how well it made use of the main results throughout :)

Great puzzle. Including my favourite type of modular lines - ignorable till they solve themselves. Thanks for setting

Sublime! I stared at the puzzle this morning in total wonder, gave up, noticed the title this afternoon and then suddenly understood what I was supposed to do. Really smooth and beautiful puzzle after the break-in. Thank you
Die Hard: I had hoped someone would get an ah-ha moment from the title, and I am glad it was you!

I found it very tricky and possibly would not have gotten there without some assistance. (Thank you, Calvinball!) But what a fantastic ride this has been! If you keep asking questions, the grid gives and gives and gives. Thank you for this wonderful construction, Die Hard!
Die Hard: I especially liked how the kropkis interacted with the various types of lines. I'm so glad you enjoyed it and thank you!

Very enjoyable, and not actually so tricky.
