Enjoyable, after getting the hang of the "full rows/cols" variant it became like popping packing bubbles.. I kind of wanted to keep playing with the kaleidoscopic shapes you can make with the near-complete positions.

I'd seen the "adjacent only" variant before but not the other two, I'm glad the default was one I hadn't seen or I might not have noticed there was a choice!

Have you considered allowing the all-white state as a terminal state too? First time I completed it was with a detour to there (I know the text says make them red but my instincts went with the lights-out being to the color matching the background)

Thanks for the diversion. On the 5x5 my scores went from ~100 to dozens (sometimes 8-10). On larger boards I'm not as consistent but also not as interested in path length.
