What is Lightout?

Lightout, also known as Lights Out or Lights Off, is a puzzle game that involves turning off all the lights on a grid. The game was invented by mathematician and programmer, Eric Solomon in 1995. It gained widespread popularity in the 1990s, especially with the release of the electronic handheld version by Tiger Electronics.

How to Play

The Lightout game consists of a rectangular grid of lights, which can be either on or off. The goal of the game is to turn off all the lights, ideally with the minimum number of moves.

Each move in the game consists of pressing any of the lights on the grid. Pressing a light will toggle it and its adjacent lights on or off. For example, if you press a light that is on, it will turn off, and its adjacent lights will turn on. If you press a light that is off, it will turn on, and its adjacent lights will turn off.

The catch is that pressing a light will also affect the adjacent lights on the same row and column. This means that you have to think about the sequence of moves you make to turn off all the lights on the grid.

Solving Strategies

As mentioned earlier, Lightout may seem simple, but it can be quite challenging to solve. There are a few strategies that can help you beat the game:

  • Work from the edges: Start from the edges and work your way inwards. This strategy can help you reduce the number of moves and simplify the game board.
  • Unpressing: In some cases, you may have to undo some of your previous moves to turn off a light. This technique is known as “unpressing.”
  • Patterns: Pay attention to patterns on the grid. Some patterns only require a few moves to solve, making the game easier to beat.

Online Versions

If you don’t have a physical Lightout game, you can still enjoy it online. There are hundreds of online versions of the game, from simple ones to more complex and challenging ones.

One of the most popular online versions of Lightout is available on Simon Tatham’s Portable Puzzle Collection. The game is free to play and offers a variety of grid sizes and difficulty levels for you to choose from.

The Lightout Effect

Aside from being a fun and challenging puzzle, Lightout has also been used in various studies and experiments. Researchers have studied the effects of playing Lightout on problem-solving and critical thinking skills, and some have even used it to uncover patterns in neural networks.

“The Lightout game is an excellent tool for testing the hypothesis that people modulate the attentional focus they apply to the world to optimize perceptual performance.” – Taito Sakurai, Behavioral Scientist

So the next time someone says that playing games is a waste of time, you can tell them about the Lightout effect.


The Lightout game is not just a classic puzzle; it is also a symbol of simplicity and versatility. It has been adapted into various versions, and is still being studied and used in different fields today. So the next time you’re looking for a mind-boggling challenge, give Lightout a try, and experience the satisfaction of turning off all the lights.
