The essentials of playing Lights Out
Use a short break to learn the rhythm of Lights Out. Turn every light off. Every supplied starting state is made by valid flips from an all-off board and is therefore solvable. Keep the game area visible while you use its controls. Treat the first round as a chance to learn the controls. Look at what changes after your first action.
Practice with a purpose
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. An attractive position is not enough unless the goal is met. The example below illustrates a decision.
Follow these playing steps
- 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.
Your inputs
Use the on-screen controls with a mouse or touch. Read a button’s label before selecting it. Use the visible help when you are unsure of the next input.
A closer look at one 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. Notice the change in the playing area.
Avoid this misunderstanding
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. After a move, check what changed. Decide which rule explains the new state before acting again.
