About Lights Out Game

Lights Out is a classic electronic puzzle game that challenges your logical thinking and strategic planning. The board consists of a grid of lights. When the game starts, a random pattern of lights is turned on. Clicking any light will toggle its state, as well as the states of its adjacent neighbors (top, bottom, left, and right). Your ultimate goal is to switch off all the lights on the board.

How to Play Lights Out

Mastering Lights Out requires careful planning and pattern recognition:

Click to Toggle: Tapping a tile switches it from on (yellow) to off (dark), and does the same for its direct orthogonal neighbors.
Choose Your Challenge: Select between 3x3, 4x4, or 5x5 grid sizes using the difficulty selector to match your skill level.
Minimize Moves: Try to clear the entire board using the fewest moves possible to set your personal best.
