Lights Out: A Mathematical Grid Puzzle Game

By

Summary

The article describes 'Lights Out,' a mathematical puzzle played on an n×n grid where cells are either red or white. The objective is to make all cells red by clicking on cells, which flips the color of the clicked cell and its adjacent neighbors (north, east, south, west). The original version uses a 5×5 board with this adjacent neighbor flipping rule.

Lights Out is a mathematical puzzle that lives on an $n \\times n$ grid where each cell of the grid is one of two colors: either red or white.
The goal is to eventually get all the cells in the grid to be red.
Clicking a cell will not only flip the color of that cell, but also flip the color of all the neigbors to its north, east, south, and west (call this rule Adjacent).
The original setup involves a $5 \\times 5$ board, on whose cells a user may 'click.'
