Heterochromia (Killer Sudoku)
(Published on 30. March 2021, 00:42 by emmettcito)
A killer sudoku with only 10 cages! I still can't believe this has a unique solution, let alone one with a logical solution path.
Rules: all standard sudoku rules apply. Digits in a cage must not repeat and sum to the number in the upper left corner of the cage.
This puzzle is also available on f-puzzles
Solution code: Row 9 and Column 9

The break-in is very elegant and the 'helper' cages ;-) extremely well-chosen. I'm a sucker for minimalism.
Der Einstieg ist sehr elegant, und die 'Helfer'-Käfige sorgfältigst ausgewählt. Hat mir in der Minimalistik sehr gut gefallen!

Absolutely wonderful! What I love about it is how the break-in isn't necessarily hidden, it is mostly tricky because it needs to be carefully executed. And then once you think you cracked it, there is another obstacle. What a beautiful puzzle.

This is a sudoku delivered from the heavens! It looked like there wasn't enough information, but slowly it revealed its secrets. This is one of my favourite killer sudokus I've ever solved. :-)

@abed hawila and @CaneloC thank you :) I purposefully designed this to make it still put up a lot of resistance and require
some interesting logic after the break in.

Incredible puzzle! Very nice break-in and the mid-solve logic was also interesting. :-D

Unbelievable puzzle!

I enjoyed this a great deal. It is probably the most involved break-in that I have ever successfully found (speaking as a relative newcomer to Sudoku variants), and even after figuring that out it still took me most of an hour and required some logical leaps. Nice work.
