### Friday Puzzles #54

Again, I find myself in two minds as to how this puzzle ought to be classified. You see, the problem is most Hashi that I do are fairly generic, and probably require a solving set of about five moves applied with various degrees of imagination. With this Hashi, there are two polarised solving experiences that I can envisage you, dearest reader, having. Either something clicks, and everything gets pretty standard pretty quickly, or else you’ll struggle a little bit and the solve will turn into something of a slog.

It seems to me that the best case scenario for me as the author is that everyone manages to click. In which case there seems to be only a minor pay-off before everything gets standard. Still, having steadfastly argued earlier this week that an otherwise unspectacular puzzle still had some merit to it based on a novel and interesting move to finish it off, I suppose I should be happy with this. Enjoy!

Update: My thanks to Bryce Herd who pointed out that an earlier version of this puzzle failed to satisfy a basic theorem of graph theory!

### Friday puzzles #53

Well, there are two puzzle due before the end of the day if I’m going to get my numbering on track, and both of them are going to be Hashi. If you’ve never seen this puzzle before – after all, it is the first time they’ve been featured on this blog – then as ever there’s a handy link in the “How To Play” section there on the left.

This should be a nice warm-up for you – there’s a harder one coming this evening. After all, if you can’t win a game of noughts-and-crosses (or, I guess, tic-tac-toe for my American readers) then at least you should be able to solve a puzzle! :)
