Friday Puzzles #134

I was up quite late last night writing puzzles, with the intention of putting up a sudoku puzzle. But apparently I wasn’t quite up to it, and went back to some loop puzzles. I thought yajilin might be a good idea, firstly because I’ve been having a little fun playing with some relatively unknown tricks, and secondly because it gives me a chance to give an alternative presentation another go. I think the way I’m currently rationalising things is that the bordered squares represent holes in the grid, and whether you put clues in these holes is up to you. This works perfectly provided you don’t have too many holes next to each other!

Anyhow, you’ve been spoiled this week, dearest reader, because here are two puzzles to brighten your day. Or something like that. Enjoy!

#164 Yajilin – rated easy

#165 Yajilin – rated hard
