Rules, controls and help for 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. Keep the game area visible while you use its controls. Treat the first round as a chance to learn the controls. Look at what changes after your first action.
Practice with a purpose
After a move, check what changed. Decide which rule explains the new state before acting again. 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. Keep that objective in view throughout the round. Try to explain the aim in your own words.
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.
Making selections and moves
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.
See the idea in action
Tapping the centre changes five cells. Tapping a corner changes three. Diagonal neighbours are not affected. Use the example as a guide rather than a substitute for reading your board. Keep the game’s format in mind.
Pay attention to this rule
An unlit tile can still be tapped; it may be necessary to solve the board. Compare the situation with the worked example. Locate the buttons and input area before beginning a long round. Use the on-screen labels to avoid an accidental restart.
