Line of Sight Chaos Production (9x9)

(Eingestellt am 4. Februar 2022, 03:10 Uhr von RockyRoer)

Since a 7x7 version of this puzzle was well received, here's a full size version.

The Rules

  1. Normal Irregular Sudoku Fill each row, column and 9-cell region with the digits from 1-9. The boundaries of the regions must be determined by the solver.
  2. Line Of Sight Products Clues in the grid indicate some of the cells that can see at least two cells in its same region both horizontally and vertically. Every digit it sees horizontally is summed, and every digit it sees vertically is summed, and these sums have been multiplied together. Region boundaries stop the line of sight.

    Examples:

    • The 30 clue in the example puzzle sees 1+2 vertically and 5+2+3 horizontally and 3*10 = 30.
    • A clue could not have been placed in R3C3 because it does not see at least two cells vertically.
Example:
Play on f-puzzles or on CTC App

The Puzzle

Play on f-puzzles or on CTC App

Lösungscode: The number of regions in each row from top to bottom, followed by the digits in column 4. (For the example it would be 2332141523)

Wow, took me a while to figure out one of the tricks (will not tell precisely which one here, not to spoil anything...), but I finally saw the light ! Great construction and great use of prime numbers as a hidden constraint ! Loved it !

Reply: Yay! So glad to see you finished and that this puzzle has an official rating now! Now that it’s been a few months, I need to try it again as I have forgotten many of the tricks!

It seems like the 700 clue didn’t work out very nicely. ;) I should give this one a try.
