Took me almost 77 minutes, it was hard at first to spot things, but once you understand how to move, you have a lot of fun :)

Solved as part of a group solve on Twitch, beautiful puzzle!

I wouldn't have thought it possible to have a classic deconstruction with fewer givens than are required for a normal sudoku. Amazing discovery!

Nice proof of concept with some neat leftover logic. It's counterintuitive that the minimum number of given is this much lower for a Deconstruction.

This is a puzzle for the connoisseurs of Sudoku curiosities - and also solvers who like an interesting challenge - it defies belief that such a construction is possible. The solve is challenging in parts, it is true, but what do you expect in a puzzle with just 14 given digits? lepton, thanks so much for this wonder.

Cool puzzle! Interesting that less givens are needed than for a classic sudoku.

10x10 threw me for a start. I had assumed 11x11 before counting, as that is usual for deconstruction puzzles.
But a very nice challenge. Took me a good while but nut unreasonable time.
