The essentials of playing Lights Out
Choose a round of Lights Out and settle into its rules. 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. Check the rule that explains your first action. Choose a clear next step rather than rushing through the instructions.
A small practice goal
Keep the stated aim separate from side details such as animation or appearance. Progress is measured by the game’s own completion or scoring rules. Refer to the controls when needed.
What counts as success
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. 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.
Your inputs
Use the on-screen controls with a mouse or touch. Use the control method described here for this activity. A new-round button replaces the current round.
See the idea in action
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. Verify the rule before continuing.
Avoid this misunderstanding
An unlit tile can still be tapped; it may be necessary to solve the board. Compare the situation with the worked example. Locate the buttons and input area before beginning a long round. Use the on-screen labels to avoid an accidental restart.
