Lights Out

How to play

The classic toggle puzzle on a 5×5 grid. Clicking a light also toggles all of its orthogonal neighbours. Turn every light off to win.

Rules

  • Click any light to toggle it and its up-to-four orthogonal neighbours.
  • A lit cell glows yellow; an unlit cell stays dark.
  • Your move count is tracked live below the grid.
  • Turn every light off to win.

Tips

Work top-to-bottom, row by row — fix row 1 by clicking the lights directly below any that are still lit in row 2, fix row 2 the same way using row 3, and so on down the board.
