Lights Out: a guide for your next round
Open Lights Out, check the instructions and begin a round. 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. Choose a comfortable screen position before beginning. Keep the game area visible while you use its controls.
A focus for your next round
Before your first action, say what you are trying to achieve. Then compare the result with the goal. Notice the feedback after each input.
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. Try to explain the aim in your own words.
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.
Using the playing area
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.
One way to understand the rules
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. Read the matching step again.
A common point of confusion
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. When a decision goes wrong, compare it with the common mistake described below. Start again only when you intend to leave the current round.
