How to play Lights Out
Choose a round of Lights Out and settle into its rules. 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. Keep the instructions close while learning this activity. Choose a clear next step rather than rushing through the instructions.
Something to practise
Before your first action, say what you are trying to achieve. Then compare the result with the goal. Use the example to check your reasoning.
Your objective
Turn every light off. Every supplied starting state is made by valid flips from an all-off board and is therefore solvable. Keep that objective in view throughout the round. Take a moment to understand the current position.
How a round unfolds
- 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 interact with the game
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.
Learn from a sample situation
Tapping the centre changes five cells. Tapping a corner changes three. Diagonal neighbours are not affected. Apply the same reasoning to the position in your own round. Verify the rule before continuing.
Avoid this misunderstanding
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. Watch the feedback after an action. A message can explain whether the input was accepted or whether a rule needs attention.
