Your guide to Lights Out

Try Lights Out at your own pace and keep its objective in view. Turn every light off. Every supplied starting state is made by valid flips from an all-off board and is therefore solvable. Look at what changes after your first action. Choose a comfortable screen position before beginning. Choose a clear next step rather than rushing through the instructions.

Build familiarity through play

Locate the buttons and input area before beginning a long round. Use the on-screen labels to avoid an accidental restart. Use the example to check your reasoning.

What counts as success

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.

Step by step

  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.

Choosing and moving on screen

Use the on-screen controls with a mouse or touch. Read a button’s label before selecting it. Check any mode label before starting.

Put the rules into context

Tapping the centre changes five cells. Tapping a corner changes three. Diagonal neighbours are not affected. Use the example as a guide rather than a substitute for reading your board. Consider the next action carefully.

Notice this detail

An unlit tile can still be tapped; it may be necessary to solve the board. A different version of the game may use a different rule. Choose one rule to keep in mind for this round. Apply it consistently rather than guessing what another version might allow.
