Interval Sums

(Published on 30. October 2021, 12:42 by RockyRoer)

The Rules:

  1. Normal sudoku rules apply.
  2. Interval Sums: Let A and B are the two cells nearest an outside clue. Then the outside clue represents the sum of the digits in positions A through B. Some examples are shown in the solution to the 6x6 example in the picture.
    • Example: 4 [231564] 15
      The 4 clue sums the digits in columns 2 through 3 (3+1=4)
      The 15 clue sums the digits in columns 4through 6 (5+6+4 = 15).
  3. In the full puzzle, the three clues marked x must sum to the same total (which must be deduced). The two clues marked y must sum to the same total which must be deduced. x and y may or may not be the same.

Fun concept; solves nicely!

I kept having to remind myself that the positions are absolute positions, i.e. counted from the top/left rather than from the direction of the clue (which would have been more intuitive for my brain).

REPLY: Thanks for solving! And yes -- I toyed with the variation you described for a bit too - but eventually settled on keeping the positions absolute because then it is symmetry breaking.

Always appreciate the early comments!
