Friday Puzzles #21

So perhaps things have been getting a little too mathsy; and certainly I could do with a sudoku break. So, here are a couple of easy Heyawake puzzles, themed with a small number of numbered rooms. Obviously when you focus on just one of the rules of a puzzle, then you lose some of the richness and variety, and this is the case with these two puzzles. As such they are both pretty easy. Still, I hope they still prove to have at least some fun factor coming from their novelty value.

I am wondering whether it is possible to do a Heyawake puzzle with no numbered rooms at all – at this stage I’m sort of conjecturing that with enough fiddling about with thin rooms in the corners it ought to be doable…whether that translates into any sort of a fun solve we shall have to see.

  1. It has been done before apparently, according to glmathgrant here: http://glmathgrant.livejournal.com/5427.html

    He did note however that it was not a fun solve. :P

  2. Cheers for the link – the ambiguous room puzzle is here: http://www.janko.at/Raetsel/Heyawake/031.a.htm . It’s a bit small but I think it’s fairly pointless trying to make a puzzle like that any larger.

    The glmathgrant puzzle with just that one initial empty room was interesting too. I wouldn’t say elegant, but definitely interesting.

    Congratulations on being a far more prolific puzzle writer than I am by the way!
