Lights Out: learn through an example

Start Lights Out by looking at the playing area and its controls. 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. Choose a comfortable screen position before beginning. Choose a clear next step rather than rushing through the instructions.

Take a closer look while playing

After a move, check what changed. Decide which rule explains the new state before acting again. Notice the feedback after each input.

The challenge in front of you

Turn every light off. Every supplied starting state is made by valid flips from an all-off board and is therefore solvable. Use the instructions to see which actions move you towards it. Try to explain the aim in your own words.

Making your moves

  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.

Your inputs

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. Compare this with the rule that governs the move. Take a moment to compare.

Keep this in mind

An unlit tile can still be tapped; it may be necessary to solve the board. Read the feedback to see why an action did not have the expected result. Before your first action, say what you are trying to achieve. Then compare the result with the goal.
