Mounting Pressure (Between Lines)
(Published on 3. September 2024, 11:57 by Blashyrkh)
Mounting Pressure
My first time using Between Lines! Not an easy constraint to work with, but in the end I managed to implement my ideas.
I think I got some pretty unusual logic out of the lines, so the puzzle turned out quite challenging.
Thanks to Fool On A Hill from the CtC Discord for testing and discussions :)
Rules:
- Sudoku: Place the digits 1-9 into every row, column, and box.
- Between Lines: Digits along a grey line must be strictly between the digits in the attached circles.
Solution code: row 5

Absolutely incredible. Took me over 170 minutes, worth every second

You and geometry are a dangerous combination.

I would like to join the choir and give props to the creator for this beautiful puzzle. It deserves the five-star rating, but when you are done and go through the steps again, you realise how simple it could've been if you understood the logic from the start. Elegant and a must-solve for anyone in doubt.

I know it's been almost a year, but I just realized this is one of the greatest pieces of feedback I have ever received.
"but when you are done and go through the steps again, you realise how simple it could've been if you understood the logic from the start."
What better reaction is there to elicit from a solver? This is exactly what I am aiming to achieve - puzzles that are impervious to case-bashing, but crack when the proper razor-sharp logic is applied :D

This was so brutal, I spent almost a hour only thinking about what was going on with those circles. Brilliant idea :)

I had something of a headstart on this puzzle having used those Between line shapes myself (see 'Tete a tete'). Even so, I thoroughly enjoyed solving this and it was an excellent construction!

Just wonderful! This is a very intricately set puzzle that only reveals its secrets after intense questioning. It is also very rewarding. Thanks a lot for this beautiful construction, Blashyrkh!

Cool puzzle - I'm so glad you got the thematic logic to work - it was a pleasure to work it out

Mounting pressure? Yeah, enough to make a diamond. Great job!
