Lights Out: rules and examples

Use a short break to learn the rhythm of Lights Out. Turn every light off. Every supplied starting state is made by valid flips from an all-off board and is therefore solvable. Use the example below to understand a decision. Treat the first round as a chance to learn the controls. Look at what changes after your first action.

Try a more deliberate round

Keep the stated aim separate from side details such as animation or appearance. Progress is measured by the game’s own completion or scoring rules. Notice the feedback after each input.

Your objective

Turn every light off. Every supplied starting state is made by valid flips from an all-off board and is therefore solvable. An attractive position is not enough unless the goal is met. Return to the instructions when a step is unclear.

Start here and follow along

  1. Select a light or an unlit tile.
  2. The selected tile and its orthogonal neighbours switch state.
  3. Plan flips so that previously cleared rows stay cleared.
  4. Use Undo to try another approach.

Controls

Use the on-screen controls with a mouse or touch. Keep the playing area visible while using these controls. Return to the rules if the result is unexpected.

Work through an example

Tapping the centre changes five cells. Tapping a corner changes three. Diagonal neighbours are not affected. Focus on why the action is allowed, not only its outcome. Verify the rule before continuing.

One detail worth checking

An unlit tile can still be tapped; it may be necessary to solve the board. Compare the situation with the worked example. Choose one rule to keep in mind for this round. Apply it consistently rather than guessing what another version might allow.
