This is a puzzle I made about a month ago. It’s one of the few puzzles I feel I actually constructed, as opposed to just browsing the shelves of the Puzzle Library of Babel, trying layouts and seeing what works out.
I set out to make a harder version of Hitori. I’m not quite sure whether the puzzle successful or not, as it isn’t that hard. Adding blank cells as givens might improve the puzzle.
I hope I was clear with the rules.
