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. 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.
Notice the feedback
Watch the feedback after an action. A message can explain whether the input was accepted or whether a rule needs attention. Keep the objective visible.
Your goal
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. Check the rules when you are unsure.
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. Read a button’s label before selecting it. Return to the rules if the result is unexpected.
A useful example
Tapping the centre changes five cells. Tapping a corner changes three. Diagonal neighbours are not affected. Focus on why the action is allowed, not only its outcome. Notice the change in the playing area.
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.
