X-Sums killer sudoku #2

(Eingestellt am 10. Oktober 2022, 21:08 Uhr von udukos)

Recently published puzzles from KNT and jovi_al inspired me to have another go at this ruleset.

Normal sudoku rules apply.

An area surrounded by a dashed line is called a cage. Digits may not repeat within a cage. The numbers outside the grid are X-Sums clues. They indicate the sum of the first X cells in the row/column from that direction, where X is the first number in that row/column.

A double-digit X-Sums clue inside of a cage prevents both of its digits from appearing anywhere else in the cage (this does mean 11, 22, 33, and 44 are disallowed as X-Sums clues, as those would repeat digits in a cage). A double-digit X-Sums clue may include zero (10, 20, 30, and 40 are valid X-Sums clues).

Have fun! :)

What an absolutely gorgeous puzzle. 5* seem to be too less for it. What looked impossible for the first one hour of staring on two previous abandoned attempts, started to slowly look a wee bit possible on the third, and yet it kept resisting until you reach the next aha moment. Pure joy. Thanks, @ udukos:). It is a miracle that this can even exist.

How the hell...

Instantly added to the favorites list. Wow wow wow. A miraculous construction with one of the most amazing solving paths I've experienced in a while. Thank you so much udukos, and I'm so glad I could inspire you to make this.

Wonderful puzzle - clean logic and some really nice deductions.

Note in case it helps anyone: Xenonetix in "A Mathematical Phenomenon" introduced me to a pencil-marking scheme for outside double digit numbers on the CtC app, which I found very useful here - corner marks for 10s digits and centre marks for units.

I find it incredible that such a puzzle without cage totals even exists, let alone the beautiful solving path. Thanks a lot for this treat, udukos!

Such an incredible puzzle! It's quite unbelievable that no cage totals are given and it solves so smoothly. Great job :)
