Welcome to PuzzleZite!

This site contains several puzzles based around the popular handheld game Lights Out. The aim of the game is to extinguish all the lights on the playing board by pressing buttons on the playing board. Pressing a button on the board doesn't just toggle on and off that light however, it also toggles the 4 adjacent lights to that button (diagonal buttons remain unaffected).

Here is an example board for you to look at. You can see that some of the nodes are lit (represented with the colour green and the number 1). Clicking anywhere on the board will cause the selected node, and the adjacent nodes (the shape shown on the board) to toggle on or off. Try clicking anywhere on the board to see the behaviour for yourself.

Solution:

The obvious solution to this puzzle is to click the center node.
