This puzzle continues my series which utilizes lines that are both region sum lines as well as another line constraint, this time being paired with entropic lines.

Rules:

Normal Sudoku rules apply.

All lines are both region sum and entropic lines.

-- Region sum lines: Digits along a line must sum to the same total in each region the line enters.

-- Entropic lines: Each set of three consecutive digits on a line must be one each of a low [123], middle [456] and high [789] digit.
