Build Your Own Lockout Lines
(Published on 10. September 2022, 20:46 by wooferzfg)
This puzzle was created by Jakhob and wooferzfg.
Normal Sudoku rules apply.
There are hidden lockout lines in the grid. Each pair of diamonds with the same letter must be connected by a line. Lines can only move orthogonally and cannot branch. Lines cannot cross themselves, other lines, or other diamonds.
Digits on a lockout line cannot be between or equal to the digits on the diamond endpoints. Digits on the endpoints must differ by at least 4.
Here is an example puzzle on a 6x6 grid, with endpoints required to differ by at least 2:
Solution code: Row 3 followed by Row 4

Built it ! Looks like electric schematics when it's done. And you litterally telegraphed this one with letters :)

I typically am frustrated by lockout line puzzles. I haven't seemed to crack instinctual logic in them like I have other variants. But, this version of it was so thoroughly enjoyable. It was clever and interesting. It unfolded neatly, but I never felt it was obvious. It was continuously rewarding up until the end.
