I Refuse to Give Sums!

(Eingestellt am 26. April 2023, 18:07 Uhr von 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:

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

Very, very clever setting! I admit to having had to bifurcate filling in my first digit... Despite having already filled in an awful lot of info, I could not see how to get that first digit with a short enough logical chain to hold in my head without writing it in.

Thanks for solving! Yeah, there is a kinda difficult to spot deduction to get the first digit, but there is a clean way to see it

This puzzle is a masterful work of art created by a true person of genius! It is still hard to believe that it solves and has a unique solution. Every logical deduction is a clear and non-trivial one and it gives you a right feedback as you are able to get it. The balancing and feedback around the grid is just amazing. At some moments you may feel to have broken the puzzle - but that’s just a virtual feeling, and as you believe to have broken in - this is also a dubious thing, as the puzzle keeps resisting right until the end. Simply put, this is one of the best killer sudokus ever with a plethora of just beautiful deductions one after another. This puzzle deserves much wider attention, but it truly is pretty hard to crack. Thank you and take a bow, LittleNightmaresLady!

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)
