Rules, controls and help for 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. 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.

An idea for your next attempt

Before your first action, say what you are trying to achieve. Then compare the result with the goal. Keep the objective visible.

Aim for this result

Turn every light off. Every supplied starting state is made by valid flips from an all-off board and is therefore solvable. Keep that objective in view throughout the round. Review the board or playing area as it changes.

How a round unfolds

  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.

The controls to know

Use the on-screen controls with a mouse or touch. Use the control method described here for this activity. Contact us with the game and device if a control does not respond.

Follow the example

Tapping the centre changes five cells. Tapping a corner changes three. Diagonal neighbours are not affected. Apply the same reasoning to the position in your own round. Keep the controls nearby.

Pay attention to this rule

An unlit tile can still be tapped; it may be necessary to solve the board. Take a moment to reassess the position before continuing. After a move, check what changed. Decide which rule explains the new state before acting again.
