Lights Out: what to know before playing
Lights Out gives you a focused activity to play in your browser. 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. Make your first input carefully and watch the result. Use the example below to understand a decision.
Build familiarity through play
Before your first action, say what you are trying to achieve. Then compare the result with the goal. Keep the objective visible.
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. Start with a deliberate move.
From the start of a round
- 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.
Controls
Use the on-screen controls with a mouse or touch. Keep the playing area visible while using these controls. Make sure you are interacting with the game rather than the surrounding page.
Work through an 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. Verify the rule before continuing.
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. Take enough time to read a new position. If a game has a timer, learn its controls first rather than searching for them during the round.
