Great puzzle! I lost a few hours by focusing on the wrong digits combined with a silly and wrong assumption. Luckily I realized my mistake in the end and then the puzzle unfolded really nice. Thank you for this wonderful puzzle and for your generous and flattering reply to my comment on the previous puzzle of yours that I have solved. I am not sure how I deserved that, but I'll take it gladly anyway! I will certainly try some more of your puzzles next week.

Thank you so much Snookerfan! I think this is one of the puzzles I am proudest of, along with Cutting a Diamond and the Fillomino Sudoku with a Loop. I love setting in such a way that the constraints create some communication between cells that needs to be fully utilized in order to break through. I think here I fully achieved it, whereas in Cutting a Diamond I might have left the door open for Bifurcating a Diamond which is of course not the way to go:) I apologize, I am starting to ramble. Thank you as always for your solves!

Whoa, what an amazing puzzle, and it does its title justice. Not going to lie, this was an exceptionally hard puzzle for me. There were multiple break-ins required, and I loved every one of them.
