But what better than a drunken puzzle to liven up any party!? Especially one as tricky as this Heyawake. Some careful thinking is required here to avoid tripping yourself up; indeed, that’s why I had to unfortunately break the symmetry of this puzzle to make sure everything was above board. Still, the solve itself was well worth tinkering with to get right, and so that’s why this one gets to be published. Enjoy!

P.S. Incidentally, I thought the Hitori yesterday was harder than this puzzle – but a very helpful testing session with this puzzle has probably changed my mind. Thanks Agnieszka!
