The penultimate puzzle in the entropic lines introductory series! JeremyDover and I offer another entropic lines puzzle, this time pairing with the anti-king constraint.
If you are new to entropic-lines we recommend to start with an easier puzzle of this series or watch this video by BremSter first.
Rules
Normal sudoku rules apply.
Anti-king rules apply: Two cells adjacent either orthogonally or diagonally cannot contain the same digit.
Entropic Lines: Any set of three sequential cells along an entropic line must contain a low digit (1-3), middle digit (4-6) and high digit (7-9). Digits may repeat on a line, if allowed by other rules.
CTC
This is puzzle #5 of the entropic lines introductory series.

Lovely puzzle! I echo nyxie's comment though - I got a surprisingly far way through before remembering the anti-king constraint, at which point it solved very very quickly. I suppose that is kind of an inevitable "issue" (if you want to call it such) with this combination of one early-game and one late-game constraint.

Much easier once I remembered there was an anti-king constraint!
