[This is a repost from our archives with new notes at the top: This Nurikabe (original post) still draws from some aspects of Nikoli puzzles at the start, but by the end starts to apply more global constraints and visualization that is very rarely seen from that publisher. Whether this is that they have a different audience than mine or something else is an interesting discussion. Fifteen years ago I learned from many of the styles/ideas they published; one goal of mine is to see that future generations of solvers draw inspiration from my prior work and my own style of puzzle design.]
