Nurikabe by Thomas Snyder

[This is a repost from our archives with new notes at the top: The final Nurikabe (original post) of week two was one of our “best of” puzzles in our launch year 2013, with an interesting visual clock theme and again a different kind of use of wide open white spaces for that unexpected number (if it was going to be anything, it had to be a 13! There might come a time you might need a clock that can point at that).]
