How to play

Learn the objective before jumping into a new run.

  • Choose Easy 4x4, Standard 5x5, or Hard 6x6, then tap lights to toggle them.
  • Each tap flips the selected light plus its up, down, left, and right neighbors.
  • Clear the board by turning every light dark.

Controls

Keyboard and touch instructions for this game.

  • Mouse or touch: tap a light to toggle it and its four neighbors.
  • Keyboard: tab to a light and press Enter or Space.
  • Use New puzzle to generate a fresh solvable board.

Tips

Small habits that can improve your score.

  • Work from the top row downward so earlier rows stay solved.
  • If a light remains on in a row, press the cell directly below it in the next row.
  • Hard boards are still solvable; they just need more careful row-by-row planning.
