Read before your next round of Lights Out
Use a short break to learn the rhythm 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. Use the example below to understand a decision. Choose a comfortable screen position before beginning. Keep the game area visible while you use its controls.
A focus for your next round
Locate the buttons and input area before beginning a long round. Use the on-screen labels to avoid an accidental restart. Make the next step deliberately.
The goal to keep in mind
Turn every light off. Every supplied starting state is made by valid flips from an all-off board and is therefore solvable. The feedback beside the game helps you follow the round. Follow this game’s rules rather than another version’s.
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.
How your actions work
Use the on-screen controls with a mouse or touch. Use the control method described here for this activity. Avoid pressing the same control repeatedly while a move is being processed.
See how the rules apply
Tapping the centre changes five cells. Tapping a corner changes three. Diagonal neighbours are not affected. Apply the same reasoning to the position in your own round. Keep the game’s format in mind.
Watch out for this
An unlit tile can still be tapped; it may be necessary to solve the board. Check the rule before repeating the action. After a move, check what changed. Decide which rule explains the new state before acting again.
