Show HN: Darkenn – Lights Out style puzzle game with global leaderboard

from the show-hn dept.

I used AI coding tools to create a single-player logic game called Darkenn. It is like a single player version of Go. Every move flips one cell and its neighbours. Under the hood it is linear algebra over GF(2), and the solver computes a minimum-move solution rather than just any solution. I have been personally drawn towards games and what they teach us. Darkenn teaches us seeing dependencies over one action and its flow towards the final goal.

Fun! Would you want to write up the math of how this works?

EDIT: clicked through to the "About the game" section. Nice.

During development of the game I went through many articles on how the math of of this works, some notable ones are: 1. https://oeis.org/A093614 & https://mathworld.wolfram.com/LightsOutPuzzle.html 2. https://imois.in/posts/the-properties-of-lights-out-the-game...

I was not expecting an OEIS reference. You must have had a lot of fun with this one. Thanks for the links!
