Lights Out: how a round works
Open Lights Out, check the instructions and begin a round. 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. Treat the first round as a chance to learn the controls. Look at what changes after your first action.
Practice beyond the first move
Read one step at a time and try it on the playing area. Match the instruction to the control you use. Notice the feedback after each input.
Understand the aim
Turn every light off. Every supplied starting state is made by valid flips from an all-off board and is therefore solvable. Read that aim before choosing your first action. Try to explain the aim in your own words.
How to proceed
- 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 your actions work
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. Use the example as a guide rather than a substitute for reading your board. Consider the next action carefully.
Pay attention to this rule
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. Compare the worked example with your own position. Use the reasoning, not an answer copied from a different board.
