Lights Out: rules and examples
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. Look at what changes after your first action. Choose a comfortable screen position before beginning. Keep the game area visible while you use its controls.
Something to practise
Before your first action, say what you are trying to achieve. Then compare the result with the goal. Make the next step deliberately.
What you need to achieve
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. Follow this game’s rules rather than another version’s.
Making your moves
- 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.
How to use the controls
Use the on-screen controls with a mouse or touch. On a smaller screen, keep the active part of the board within view. A new-round button replaces the current round.
Work through an 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.
Check this before moving on
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. Choose one rule to keep in mind for this round. Apply it consistently rather than guessing what another version might allow.
