Numbered Corridors 1 (Entropic Lines, Numbered Rooms)

(Published on 30. January 2023, 15:00 by Crusader175)

First puzzle of my Numbered Corridors series, exploring Numbered Rooms or Numbered Sums clue forms lines constraint.
Rules:

Normal sudoku rules apply.

Entropic Lines: Any set of three sequential cells along a peach line must contain one low digit (1,2,3), one middle digit (4,5,6), and one high digit (7,8,9). An entropic line of length 2 may not contain two digits from the same strata.

Numbered Rooms: Clues outside the grid indicate the digit which has to be placed in the Nth cell in the corresponding direction, where N is the digit placed in the first cell in that direction.

Every Numbered Rooms clue forms a straight Entropic Lines starting from the N to Nth cell (Length 1 lines is possible).

I dont understand the third rule. N to Nth? If N was 4, that would say from 4 to 4th, it would be the same cell.
Nth from the edge? Nth from the given number?

Reply: N is first cell near the clue. So it will be line of length N in that direction. Example: https://f-puzzles.com/?id=2d9a5hbl

Very interesting puzzles! Combined with the third rule in the ruleset, it also seems to make numbered rooms less intimidating.
(Because this is one of the types of questions that I am quite afraid of, I have done several related puzzles before, and each one took me a long time...)

Oh, and it's easy to make mistakes if you don't notice "N=1 is possible" when reading the ruleset.
(yes, I'm the guy who didn't notice that in the first place, and caused the answer to go wrong...)

Reply: Thank you! I try to make it not too difficult for the first puzzle in this series. Glad you like it. :)
