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. Check the relevant rule before repeating a move. Keep the instructions close while learning this activity. Use the example below to understand a decision.
Build a steady rhythm
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. Make the next step deliberately.
Your goal
Turn every light off. Every supplied starting state is made by valid flips from an all-off board and is therefore solvable. The feedback beside the game helps you follow the round. Review the board or playing area as it changes.
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. Keep the playing area visible while using these controls. Use one clear input at a time.
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. Look for the relevant detail.
Watch out for this
An unlit tile can still be tapped; it may be necessary to solve the board. Check the rule before repeating the action. Compare the worked example with your own position. Use the reasoning, not an answer copied from a different board.
