Each entry is an element of Z 2, the field of integers modulo 2. The 5×5 grid of Lights Out can be represented as a 25x1 column vector with a 1 and 0 signifying a light in its on and off state respectively. In 1998, Marlow Anderson and Todd Feil used linear algebra to prove that not all configurations are solvable and also to prove that there are exactly four winning scenarios, not including redundant moves, for any solvable 5×5 problem. Secondly, in a minimal solution, each light needs to be pressed no more than once, because pressing a light twice is equivalent to not pressing it at all. Firstly, the order in which the lights are pressed does not matter, as the result will be the same. Several conclusions are used for the game's strategy. If a light is off, it must be toggled an even number of times (including none at all) for it to remain off. If a light is on, it must be toggled an odd number of times to be turned off. The goal of the puzzle is to switch all the lights off, preferably in as few button presses as possible. Pressing any of the lights will toggle it and the four adjacent lights.

When the game starts, a random number or a stored pattern of these lights is switched on. The game consists of a 5 by 5 grid of lights. Lights to toggle to turn off a fully-lit 5×5 board
