Thorny Tie (Killer Deconstruction)
(Published on 12. July 2022, 09:00 by Agent)
Rules
- Normal deconstruction rules apply. The grid contains nine non-overlapping 3x3 regions which must be located. Each region contains the digits 1 to 9 once each, such that no digit repeats in any row or column. Cells outside regions do not contain digits.
- Digits in cages cannot repeat and must sum to 31. Cells outside regions do not contribute to the cage total.

What a puzzle! LMD needs to make its difficulty scale go up to 6, or perhaps even 11. A beautiful start - even though I did know the deconstruction secret I was slow to spot it. But then it flowed beautifully until the sudoku started and I hit a wall. I think this is one of those puzzles where you need to have a few particular insights. Very satisfying to solve, thanks Agent for a wonderful puzzle.

Absolutely brilliant. I'd say more, but this puzzle has already taken up too much of my time today :)

Beautiful grid ! Both the construction and filling part contained cool logic! Learned a lot of things about 31 cages !!
-- Thanks @Christounet, glad you enjoyed both parts of the puzzle!

What a beauty and what nicely placed gaps!
-- Thank you @bansalsaab. And yes, all the gaps are there for a very specific reason :)
