Lights Out is a simple puzzle game where you must turn off all the lights. Tap a square, and it and its neighbors' states will swap. You have the option for a quick game of a 3x3 grid, a good-length game of a 5x5 grid, or a large game of a 7x7 grid. You can choose to randomize the board, or also choose to customize the board, allowing you to set the width and height. If you wish to mute the game, the button is below the board.
This was just a quick and simple project I made over a few days. In the initial release, puzzles were unsolvable, but I have made it so that they're all solvable now.
