Richmond (Killer Diagonal)

(Published on 13. December 2022, 18:03 by tallcat)

I have had a lot of fun solving the "City Killer" series of puzzles by ICHTUES (and recommend them wholeheartedly) and they were an inspiration for setting my first killer sudoku. In setting this puzzle, I was aimins for a more more direct homage and for those interested, "Richmond" is the nearest town to where I grew up in the UK. Happy solving!

Normal Sudoku rules apply

Killer: Digits in cages must sum to the total in the top left corner. Digits may not repeat in cages.

Diagonal: The positive diagonal must contain all of the digits 1-9





Can be played online at f-puzzles or CTC

Solution code: Row 5 (left to right) followed by column 5 (top to bottom). 18 digits, no spaces.

Wonderful killer puzzle, such an engaging solve path with lots of surprises all the way! I certainly enjoyed that opening sequence the most ;)

it took me a long time to solve but i'm glad to say i didn't break it (which happens often). Very nice puzzle, thank you :)

Wow, great killer sudoku. It was very challenging but worth the effort.

I loved that. Definitely needs to be solved on CTC.

Awesome puzzle! Great job on setting and finding the nice geometry dependencies. Thanks!

One problem I had during solving is that I made a mistake in the very beginning and spent hours trying to justify my mistake. When I restarted from the beginning, everything was better. Alas, this is a problem with the solver, not the puzzle. :)

Very nice puzzle. Really enjoyed the break-in. The interaction of the cages was beautiful.

Just sublime, really enjoyable solve path even if it took me longer than I care to admit to get there.

Thanks for taking your time to set this!

Beautiful geometry, and a nice flow. The actual behavior of the diagonal was pleasantly surprising and unusual, if that's not too much of a spoiler.

Amazing puzzle! The logic is beautiful and it's really fun to work out how the cages interact. Loved it!
