Friday Puzzles #128

I’m running about as low on inspiration for a spiel this week as my laptop is its battery charge. Here’s a Nurikabe puzzle. It feels a little contrived but perhaps I’m just a little tired. Enjoy.

Friday Puzzles #127

So another Masyu again this week. I had wanted to send one of the tricks from last week to 11, but then all of a sudden it was 11pm last night and I wanted to sleep. I guess I’ll just wait until I’ve got a nice long stretch of time to myself, perhaps on a train or a plane or something. Anyway, more twisted symmetry. You’d almost think they were easy to put together! Enjoy.

Friday Puzzles #126

Wow – an entry on time – what is the world coming to!?

Well somethings never change. It’d have been really great to have pulled off this masyu with perfect symmetry, but as it is I’ve had to add an extra pearl to take the solution count down from 2 to 1. Can’t have it all eh? Still, I think there’s more than enough here to keep you entertained, and you might even need to use a slight twist on an old masyu chestnut to get you going. Enjoy!

Friday Puzzles #125

I’ve been at a wedding and will busy until at least Sunday. I’m afraid it’s more delays. In other news, I’m considering a career managing the the West Coast mainline.

EDIT

OK, here we go. Tom Collyer writes another easy sudoku. But not trivially so. Enjoy!
