Lights Out

Games

About this app

Turn off every light on a 5ร—5 grid, built with pure React (no game engine). How to play Pressing a light toggles it and its neighbors above, below, left and right. Turn every light off to solve the puzzle, in as few moves as you can.

Features

  • Numbered puzzles: every puzzle has a number from 1 to 99,999. The same number always gives the same board, so you can replay it. The game opens on a random puzzle.
  • Every puzzle is guaranteed solvable.
  • New puzzle picks a random number, or type a number under Play a puzzle by number.
  • Move counter, Undo and Restart.
  • Best moves saved for each puzzle number in localStorage.
  • Stats: puzzles solved, how many different puzzles, average moves and fewest moves. Reset stats clears them and every puzzle's best, after a Yes / No confirmation.
  • Sound effects made with the Web Audio API (a light coming on or going off, undo and solved), with a ๐Ÿ”Š toggle.
  • Settings: theme (same as the device, light or dark), and sound on or off, saved in localStorage.
