How to play 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. Choose a clear next step rather than rushing through the instructions. Choose a comfortable screen position before beginning. Keep the game area visible while you use its controls.
An idea for your next attempt
Compare the worked example with your own position. Use the reasoning, not an answer copied from a different board. 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. Start with a deliberate move.
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.
Using the playing area
Use the on-screen controls with a mouse or touch. On a smaller screen, keep the active part of the board within view. Use the visible help when you are unsure of the next input.
Try this 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. Look for the relevant detail.
One detail worth checking
An unlit tile can still be tapped; it may be necessary to solve the board. Check the rule before repeating the action. 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.
