Rules, controls and help for Lights Out

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. Look at what changes after your first action. Treat the first round as a chance to learn the controls. Look at what changes after your first action.

Give this approach a try

Take enough time to read a new position. If a game has a timer, learn its controls first rather than searching for them during the round. Make the next step deliberately.

What you are aiming for

Turn every light off. Every supplied starting state is made by valid flips from an all-off board and is therefore solvable. Read that aim before choosing your first action. Notice how the game responds to your input.

Follow these playing steps

  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.

Put the rules into context

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. Read the matching step again.

An important reminder

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. 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.
