Lights Out: a guide for your next round

Read the aim of Lights Out, then make your first move. 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.

An idea for your next attempt

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 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. The feedback beside the game helps you follow the round. Check the rules when you are unsure.

The order of play

  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.

Making selections and moves

Use the on-screen controls with a mouse or touch. Read a button’s label before selecting it. Use one clear input at a time.

Follow the example

Tapping the centre changes five cells. Tapping a corner changes three. Diagonal neighbours are not affected. Your next round may have a different position, so inspect it before acting. Choose a deliberate next step.

Check this before moving on

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. Compare the worked example with your own position. Use the reasoning, not an answer copied from a different board.
