An Easter Miracle
(Eingestellt am 9. April 2023, 01:06 Uhr von Farkov)
Rules:
Normal sudoku rules apply.
Mark nine cells such that there is one marked cell in each row, column and 3x3 box.
The digit in the first cell of a row, column, or 3x3 box gives the position of the marked cell in that row, column or 3x3 box.
(See disambiguation below for examples).
Each digit appears in exactly one marked cell.
Othogonally adjacent digits may not be consecutive.
In boxes 1, 2 and 3 each digit's position number within a box must equal that digit at least once.
For example, in row 3 an 8 must appear in either R3C2, R3C5 or R3C8.
Disambiguation:
Example: If R5C3 is a marked cell then then R5C1 would be a 3 (row position), R1C3 would be a 5 (column position), and R4C1 would be a 6 (box position).
Clink the link to see Simon from CTC explain the rule set for the original puzzle that gave me the inspiration:

The way this puzzle came together was pretty amazing. I'll include the tale in the comments below. Enjoy :)

Once you get your grips around the ruleset (it took me a few minutes at first to understand it) the solve itself is a pleasure. Pretty easy with a really smooth flow of logic. I really enjoyed it, thank you Farkov!

Hi Farkov, I loved your puzzle. It inspired me to create a miracle sudoku with even fewer rules, which you may find interesting:

Beautiful puzzle!

Very cool. This rule was just begging for an empty grid puzzle, so I'm glad that this exists.

Mind-blowing puzzle! Very smooth too.

Lovely puzzle! Not sure how difficult it is because I could rely heavily on the logic I used in the Jay Dyer puzzle the other day/week to get through most of the break-in

I became aware of this rule set after solving a Jay Dyer puzzle that featured on CTC. That was Thursday afternoon. The next day (Good Friday) I realised that a non-consecutive constraint might be interesting with that particular rule set. I quickly discovered that the addition of that constraint actually gave a unique grid! Unfortunately, after much trying, I was unable to find a human-solvable solution path; so, on Saturday, I posted my findings in the testing section of the CTC Discord server. It was picked up by TopAutism who worked on it, like a machine I might add, for hours and, by Saturday night, was able to nail down an amazingly succinct addition to the ruleset that makes the puzzle work.
So, having searched for a blank starting grid for years, this miraculously fell into my lap in such a fashion that I went from having nothing on the morning of Good Friday to being able to post this puzzle on Easter Sunday morning. I cannot thank Jay Dyer and TopAutism enough. Without Jay Dyer's rule set, and TopAutism's hard work and genius, this puzzle simply wouldn't exist.
