Entropic Whispers
(Published on 23. May 2024, 17:23 by gdc)
This puzzle introduces a new line constraint which is a combination of entopic lines and whisper lines. It is inspired from the Run-on-nabneR ruleset from JC Godart (see LMD#F1H). Thanks to the testers!
- Normal Sudoku rules apply.
- If two digits are one or two steps apart on an entropic whisper line, their difference is 3 or more.
- For example: if r2c5 is 5, the remaining 4 cells on the line in box 2 could not contain 3, 4, 5, 6 or 7.

These lines are a new invention but I also published a second puzzle that utilizes them called Razor Blade.
Solution code: Column 6, top to bottom (9 digits)

I'm not sure if I am a fan of this ruleset.. Maybe it just doesnt suit my brain :)

@SparklePuzzle I believe r9c3 should resolve those cells, by the presence of the 8 in box 8.

I believe there is ambiguity in r249c13 but doesn't impact solution code

A delightful new Sudoku invention. This one is full of surprises and is a clean showcase of just how much potential this new line type has. An absolute pleasure to solve!

Such an inspired blend of logic, that could only come from the mind of gdc. You're the best at what you do (and what you do is very nice).
