Entropic Lines

What is the Entropic Lines rule?

Entropic Lines is a variant sudoku rule: any three consecutive digits along the line must form a full set of low (1–3), medium (4–6), and high (7–9) digits in any order.

In every puzzle here the setter’s own rules text is shown beside the board, so the exact wording for the puzzle you are solving is always one glance away. All normal sudoku rules apply unless the setter says otherwise.
