Lights Out: rules and examples
Try Lights Out at your own pace and keep its objective in view. 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. Keep the game area visible while you use its controls.
Something to practise
When a decision goes wrong, compare it with the common mistake described below. Start again only when you intend to leave the current round. Make the next step deliberately.
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. Try to explain the aim in your own words.
The playing sequence
- 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.
Keyboard and screen controls
Use the on-screen controls with a mouse or touch. A careful first action helps you become familiar with the layout. Use the visible help when you are unsure of the next input.
Follow the example
Tapping the centre changes five cells. Tapping a corner changes three. Diagonal neighbours are not affected. Focus on why the action is allowed, not only its outcome. Read the matching step again.
Watch out for this
An unlit tile can still be tapped; it may be necessary to solve the board. Take a moment to reassess the position before continuing. Read one step at a time and try it on the playing area. Match the instruction to the control you use.
