Lights Out: instructions and practice
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. 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.
A focus for your next round
Compare the worked example with your own position. Use the reasoning, not an answer copied from a different board. Refer to the controls when needed.
What the game asks you to do
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. Notice how the game responds to your input.
Step by step
- 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. A careful first action helps you become familiar with the layout. Check any mode label before starting.
An example to follow
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 controls nearby.
One detail worth checking
An unlit tile can still be tapped; it may be necessary to solve the board. Compare the situation with the worked example. 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.
