Lights Out Puzzle - Instructions

The object is to turn off all the light bulbs on the board. This game trains logical reasoning and concentration.

NOTE: The instructions below are for the old Adobe Flash version of the game.

Turn off all the bulbs on the board. Clicking a bulb toggles its own light and the lights of adjacent squares on and off.

This game includes 52 levels of mind-bending fun. The lower levels are easiest, with the game getting much harder as you progress higher and higher.

HOW TO PLAY. Your goal is to click the light bulbs in an order that results in all the bulbs on the board being lit. When the game starts, some of the bulbs are on, and some of them are off.

Clicking a bulb turns that bulb on or off, and it also switches the "state" of all bulbs next to that bulb. In other words, if the adjacent bulb is off, then it turns on and vice versa.

An evil-looking fellow sits to the left monitoring your progress. Be careful about asking him to solve the level for you (by clicking the SOLVE button). He might ask you a very uncomfortable question to see just how badly you want the solution!

If you somehow manage to solve the 52 built-in levels, click the RANDOM button to scramble the board for endless All Out fun.

As the in-game help says, "All Out is a devlish game indeed, and it will most certainly put those brain cells to the test."
