The Art of Puzzles: Cave & Nurikabe
So I've had two of my wackier puzzles published as part of Oddity week over at GM puzzles. Here's the Cave and here's the Nurikabe. And yes, you do bloody well have to prove your solutions are unique!

Friday Puzzles #186
So the whole WPC series has lost a little momentum, and of the two remaining rounds I was supposed to cover, I was lacking a bit of inspiration. I've also been writing a ton of sudoku puzzles recently, but you'll soon see some of those over at LMI, and the rest are a much more long term project.
Instead I'm going to provide another Cave puzzle, following the fun I had in putting last week's puzzle together. And yes, I suppose that is me giving support to "Cave" over "Corral." I'm not sure I have my head around the difficulty levels of Cave just yet, but I reckon this is probably on the harder side of medium. I think it's harder than last weeks anyway. Enjoy!

Friday Puzzles #185
Round 10 of the WPC was anthology, but I'm going to use this as an excuse to make a Corral puzzle. Should I persist with these, dearest reader, bearing in mind Corral is apparently a nikoli puzzle, albeit one with no set of rules I can poach from here?
For now, I'll do what I've done before, and slavishly copy from the WPC instructions. Enjoy!
Rules: (as taken from the WPC instructions)
Draw a single closed loop, going along the gridlines. The loop cannot touch or cross itself. The area enclosed by the loop represents a cave. All numbers inside the grid must be inside the cave. A number in a grid cell indicates how many cells (including the cell with that number) can be seen from that cell to the nearest wall in four directions, horizontally and vertically.
N.B. For anyone who hasn't solved these before, don't treat this as your average loop puzzle. Shading in squares which are either inside or outside (but not both!) is how you will solve these puzzles. In this respect I'd argue corral has more in common with nurikabe and heyawake than, say, slitherlink or masyu.
