Lights Off is a Lights Out clone.

Quote:

This is my version of Lights Out. It has several variants built in. You can change variants by using the sliders to the right of the game board and you play the game by trying to turn off all of the lights.

When you click on a button it toggles between its different light settings (in the most basic mode, this is a simple on/off action, but in the more advanced variants there are multiple light states). Not only that, but the lights to either side of it as well as above and below it toggle as well.
