The Lights Out playbook
Bring your attention to one round 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. Check the relevant rule before repeating a move. Begin with the solo mode shown on the page. Use the example below to understand a decision.
One thing to notice as you play
Locate the buttons and input area before beginning a long round. Use the on-screen labels to avoid an accidental restart. Make the next step deliberately.
Your goal
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. Keep the controls in easy reach.
Work through the instructions
- 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.
Making selections and moves
Use the on-screen controls with a mouse or touch. A careful first action helps you become familiar with the layout. Read the example below alongside these instructions.
Work through an example
Tapping the centre changes five cells. Tapping a corner changes three. Diagonal neighbours are not affected. Compare this with the rule that governs the move. Read the matching step again.
Avoid this misunderstanding
An unlit tile can still be tapped; it may be necessary to solve the board. Compare the situation with the worked example. Read one step at a time and try it on the playing area. Match the instruction to the control you use.
