I Refuse to Give Sums!

(Published on 26. April 2023, 18:07 by LittleNightmaresLady)

I wanted to share a killer sudoku puzzle with no given totals. I'm not really sure what difficulty it is though, but judging from testers on discord, it might be at least a 3. I hope you enjoy it!

Rules:

-Normal sudoku rules apply.
-Digits in a cage must not repeat and must sum to the number in the top left corner of the cage. A ? means a single digit sum and a ?? means a double digit sum. Note that ? and ?? aren't necessary the same for all cages.

Links:

Solution code: Row 7 followed by Column 4, with no spaces.

What a difficult puzzle, but it was rewarding every step of the way! I solved the 6x6, and this masterpiece was suggested to me. Fantastic puzzle!

Thank you for solving and feedback! It was fun to set this and I'm really pleased to hear you liked it!

Thanks for pointing me to this 9x9 after I solved the 6x6. it was definitely worth the ride ! Great puzzle, a new kind of "miracle" sudoku if you ask me...

---------

No problem and thanks for solving! It was fun to expand this idea to a 9x9, and was pleased with how it turned out. Though, I think it might be difficult to come up with another break-in if I wanted to make a second puzzle (at least with just killer cages)

F-Puzzles link was broken, so changed the setter name to #4832 to fix it. Thanks to @Realshaggy for pointing this out on Discord!

@henrypijames @FioH @wisty Thanks for solving and feedback on this! After setting the 6x6 killer with no given totals (discord archive #9429), I wanted to make a 9x9 and I'm glad to hear that it turned out nice!

One of those "looks utterly impossible" puzzles. 4½ difficulty for me and very enjoyable, even though I generally don't like killer sudokus. Simon, who's known to be a big fan of killers, is gonna love this one to death.

Might still be a 3-4/5, but upgraded the difficulty just in case (only upgraded it for the beginning, the mid-solve might just be a 3)
