Doomsday Killer Sudoku

(Eingestellt am 19. Oktober 2022, 15:50 Uhr von bodemeister)

This puzzle is a killer sudoku with hidden, non-consecutive adjacent cage sums that must be determined by the solver.

  1. Normal Sudoku Rules Apply: In each row, column, and 3x3 box, the digits 1-9 must appear exactly once.
  2. The digits in each cage form a unique sum. The sum of each cage must be determined as part of the solve.
  3. If two cages touch along an edge or corner, then the two sums of those cages must not be consecutive integers.
  4. Numbers outside the grid are the sum of the first two digits on the diagonal indicated by the arrow.
Here is an example of this puzzle type on a 6x6 grid along with its solution. You can also solve the example puzzle here.



Below is the 9x9 puzzle. It is also available online at f-puzzles and CTC. Have fun solving!


Lösungscode: Row 4, column 8

Very cool puzzle!
Cool ruleset that makes for some interesting and unusual deductions. A very intricate and complex break-in that I really enjoyed, and then it stayed difficult until the end.

Thanks for the feedback! I'm glad you enjoyed the puzzle! I had a lot of fun setting it. I totally agree the difficulty level could be 5. It's hard for me to rate since I know the puzzle well and an "intended" solve.

What an amazing puzzle! It was a tough nut to crack, but interesting, fun and well worth it. Thank you :-)

It felt like i needed a tough initial break-in and then another tough exquisite break-in in the middle, which is quite an amazing setting feat :-)

BTW, felt to me more like a 5*

Planning to solve this later but I just wanted to point out the striking coincidence between the title and the puzzle ID ("000BOY")
