Your guide to Lights Out
Bring your attention to one round of Lights Out. 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. Choose a comfortable screen position before beginning. Keep the game area visible while you use its controls.
Try a more deliberate round
After a move, check what changed. Decide which rule explains the new state before acting again. Refer to the controls when needed.
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.
Making your moves
- 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 use the controls
Use the on-screen controls with a mouse or touch. Keep the playing area visible while using these controls. A new-round button replaces the current round.
An example to follow
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. Read the matching step again.
Keep this in mind
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. Before your first action, say what you are trying to achieve. Then compare the result with the goal.
