Double Equals

(Eingestellt am 13. August 2022, 23:59 Uhr von josh_johnson)

Rules:

  • Normal sudoku rules apply.
  • Region Sum Lines: for each line, digits on the line have an equal sum N within each box it passes through.
  • Doublers: One cell in every row, column, and box contains a doubler cell. For purposes of region sum lines, a digit in a doubler cell counts for twice its value. Every digit from 1 to 9 is doubled exactly once.

Splendid puzzle, thanks, and not as horribly difficult as I thought it might be. That said, I did caught out by doubler arithmetic in box 8 and had to backtrack a little.

Based on feedback, an extra clue has been added to smooth the solve path.

Wow, wonderful puzzle! But so easy to make a mistake even being super-accurate.

It took me ages to realize that two region sums in box 7 reaching >45 does not make the box broken. It just because one of the digits is doubled.

Quite tricky, easy to make a wrong deduction and break the puzzle (as I did several times). But the logic is solid and very satisfying to figure out.
