This puzzle is a clone of the Lights Out
puzzle - and
consists of a grid of red and green lights. You can pick from 12 different varieties based on the number of rows and columns,
3 color sequences and whether to enable torus mode... for a total of 72 variations! Clicking on a light
causes that light to toggle its color. The light above, below, to the left, and to the right also toggle.
Click on the lights until all the lights are green.
