Lights Out: a guide for your next round
Read the aim of Lights Out, then make your first move. 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. Choose a comfortable screen position before beginning. Choose a clear next step rather than rushing through the instructions.
Build familiarity through play
Compare the worked example with your own position. Use the reasoning, not an answer copied from a different board. Make the next step deliberately.
Aim for this result
Turn every light off. Every supplied starting state is made by valid flips from an all-off board and is therefore solvable. An attractive position is not enough unless the goal is met. Notice how the game responds to your input.
How a round unfolds
- 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. Use one clear input at a time.
Put the rules into context
Tapping the centre changes five cells. Tapping a corner changes three. Diagonal neighbours are not affected. Your next round may have a different position, so inspect it before acting. Keep the game’s format in mind.
Avoid this misunderstanding
An unlit tile can still be tapped; it may be necessary to solve the board. Take a moment to reassess the position before continuing. 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.
