Don’t Masyu look so much better with a nice bit of symmetry!? This week’s puzzle would probably count as a medium if it were 10×10 rather than 18×10 – but perhaps that’s only because I don’t believe you can have a hard 10×10 Masyu. I’d say it’s definitely hard by nikoli.com standards. Included in this puzzle is a twist on an old chestnut, which nevertheless I haven’t seen before. Maybe I’ll send it to 11 some other time. Still, I reckon this puzzle isn’t so bad either. Enjoy!
