Every Third Knight
(Published on 4. February 2022, 17:00 by JeremyDover)
Raumplaner and I are pleased to finish up our series of entropic lines puzzle with this most difficult offering in the series, which combines entropic lines with the anti-knight ruleset. However, we are sure this is not the end of entropic lines, as we have already seen puzzles by other setters that will take entropic lines in exciting new directions!
If you are new to entropic-lines we recommend you begin with an easier puzzle of this series or watch this video by BremSter first.
Rules
Normal sudoku rules apply.
Anti-knight rules apply: cells a chess knight's move apart cannot contain the same digit.
Entropic lines: Any set of three sequential cells along an entropic line must contain a low digit (1-3), a middle digit (4-6), and a high digit (7-9). Digits may repeat on a line, if allowed by other rules.
This is puzzle #6 of the entropic lines introductory series.
previous puzzle (#5)
next puzzle (#7)
Solution code: Solution code: Row 6 followed by column 3 (18 digits, left to right, top to bottom, no spaces/commas).

Fought through step by step. No bifurcation, just a lot of small deductions. Made it to the end! Thanks!
