I'm finding my life has been consumed by Kami 2, partly because I seem to have achieved some "insight" and am able to solve the puzzles reliably, almost always on the first try.
The rules are simple: Each move consists of replacing any one contiguous colored region with one of the available colors (from a palette provided). The goal is to have filled the entire image with a single such color in a given number of moves (indicated in the toolbar).
But whatever this "insight" is, it's not enlightenment. I don't know why or how I'm doing it, I just am.
I wonder if there is some simple algorithm for solving these puzzles reliably (involving, I assume, some underlying graph theory).
