A practical guide to Lights Out
Choose a round of Lights Out and settle into its rules. Turn every light off. Every supplied starting state is made by valid flips from an all-off board and is therefore solvable. Check the relevant rule before repeating a move. Choose a comfortable screen position before beginning. Choose a clear next step rather than rushing through the instructions.
Bring this focus to a round
When a decision goes wrong, compare it with the common mistake described below. Start again only when you intend to leave the current round. Keep the objective visible.
Your objective
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. Follow this game’s rules rather than another version’s.
How to proceed
- Select a light or an unlit tile.
- The selected tile and its orthogonal neighbours switch state.
- Plan flips so that previously cleared rows stay cleared.
- Use Undo to try another approach.
Input guidance
Use the on-screen controls with a mouse or touch. Read a button’s label before selecting it. Avoid pressing the same control repeatedly while a move is being processed.
Follow the example
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. Check the stated objective.
One detail worth checking
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. When a decision goes wrong, compare it with the common mistake described below. Start again only when you intend to leave the current round.
