This amazing sudoku challenges me enough that New Line would turn my solve into a trilogy.
My solve of "Courtyard" by Sotek; a sudoku using Killer and Diagonal constraints.
I deliberately went out to do this one blind, knowing it was a hard puzzle. Apologies for the length of the video.
Update: This has now been featured by Cracking the Cryptic. Not need to recommend it any more.
