This is Lights Out as a browser game. Your goal is to turn off all lights. The catch is that each time you toggle a light all the neighbors are toggled as well.

This game is written with HTML and CSS only. No JavaScript is required! Check out the code over at GitHub.

This demo uses the :has selector. It seems that your browser does not support it. You can check caniuse for more info about browser support.
