How to play Lights Out
Make Lights Out your next activity in the game library. Turn every light off. Every supplied starting state is made by valid flips from an all-off board and is therefore solvable. Use the example below to understand a decision. Make your first input carefully and watch the result. Choose a clear next step rather than rushing through the instructions.
Notice the feedback
Watch the feedback after an action. A message can explain whether the input was accepted or whether a rule needs attention. Use the example to check your reasoning.
Your goal
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. Start with a deliberate move.
Step by step
- 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. A careful first action helps you become familiar with the layout. Check any mode label before starting.
A useful 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. Keep the game’s format in mind.
Watch out for this
An unlit tile can still be tapped; it may be necessary to solve the board. A different version of the game may use a different rule. 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.
