Somewhere Around Seven
(Published on 8. January 2025, 19:45 by sujoyku)
I like to thank ChinStrap and gdc for testing and wish you joyful solving!
DECONSTRUCTION SUDOKU
- There exist nine non-overlapping 3x3 square regions which must be located. Each region contains the digits from 1 to 9 once each, such that no digit repeats in any row or column.
- All cells that do not belong to a region contain a 0.
COUNTING PALINDROMES
- The digits on a grey line form a palindrome, i.e. they read the same forward and backward.
- Along a palindrome, there may not be two consecutive 0s.
- Any digit greater 0 that lies on a palindrome indicates exactly how many of its up to 8 surrounding cells contain a 0.
GERMAN WHISPERS
- Adjacent digits on a green line must have a difference of at least 5.
Here you can solve the puzzle online (note: solution check requires entering all 0s):
Solution code: Row 10 from left to right (11 digits from left to right)

Did this one in testing but hadn't registered my solve yet. Loved this! The counting palindrome rule made this a fresh and smooth solve throughout. Great approachable decon puzzle!

Utterly beautiful puzzle. As I am new to self constructing regions (no Idea what it is called), I had to look up some theorem that states, which 9 cells are guaranteed in boxes in a 11x11 grid, before I even could start solving, from which the whole solve was smooth sailing when following the rules. Awesome job!

Thank you for your comment, TheKyoshiroFan! I am glad you enjoyed the puzzle.

I loved it! At first I thought it was irregular regions and I thought impossible! Maybe not, but re-reading the rules sure helped! Finding the 3x3 boxes was easier for me than the sudoku. That's always a challenge on the 11x11 puzzles. Thanks for setting this Sujoyku! Impressive!

You are much welcome, RedBarchetta, thank you for your comment! It is great to know that you liked the puzzle. I agree with you that the region-building is easier than the Sudoku that follows.

I'm impressed this is your first deconstruction puzzle, it's excellent! I enjoy the open-ended nature of deconstruction puzzles when they're approachable like this one is.

Very good fun. Cool with counting constraint on the palindromes. Worked really nicely. Thanks

loved the counting palindromes (even though i totally missed the counting part for a good 20 minutes, lol)

Deconstructions are fun, and this one is no exception, but seldom are they this approachable. An enjoyable snack. Thank you!
