I was originally going to stick this hitori puzzle in yesterday – it is a much superior puzzle to Friday’s – but I felt it wouldn’t be doing this puzzle justice. I want to talk about this a little bit and that seemed out of place with yesterday’s nostalgic waffle. Suffice to say, some of the logic is quite involved in this puzzle, but what really interested me whilst constructing this puzzle was the whole idea of having so-called “minimal hitori”. The thinking here is that if the numbers in the grid which at no stage feature in any meaningful deduction weren’t even printed in then it might make for a puzzle with a nicer solving flow.
Being the sadistic contrarian that I am, I’ve decided to take a different approach. Most nikoli.com hitori usually feature an “ascending solve” – that is the first deduction will usually be with 1’s, then 2’s and so on. This is true of this puzzle – however what I’ve tried to do with superfluous clues is to disguise them (albeit on a fairly superficial level) amongst what you should really be looking for. Let me reiterate again, this is a tough solve.
Instead of writing “Sorry, Thomas”, I’ll instead go with “Sorry Thomas”. Or perhaps that should simply be: “Enjoy!” :)
