Opposite Day

(Published on 29. April 2023, 05:00 by Will Power)

Normal Sudoku rules apply. Numbers on green lines are at least 5 apart from their neighbors on the line. Numbers in cages sum to the number in the top left corner of the cage. Numbers with a white dot between them are consecutive. One of the numbers (from 1-9) appears in only one cage, in box 1. No other cages contain this number. There are no other negative constraints. Expect the unexpected.

Thanks! I saved the rule about the caged digit only in box 1 to near the end. But I never needed it in the solve! I did check it at the end to make sure I got the right solution.

Nice puzzle, I was struggling a bit with the break-in but then it went smoothly.

I had to start over several times, but that just makes the solving that more satisfying. I love your puzzles, Will Power.

I pencil-marked a guess in Box 9, thinking it would quickly lead to contradiction. Eighty digits later, all pencil-marked, I lucked into the solution. Someday I'd like to understand the proper break in on this one!
