Your guide to 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. Choose a clear next step rather than rushing through the instructions. Treat the first round as a chance to learn the controls. Look at what changes after your first action.
Try a more deliberate round
Compare the worked example with your own position. Use the reasoning, not an answer copied from a different board. Keep the objective visible.
The objective of a round
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.
Start here and follow along
- 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.
Input guidance
Use the on-screen controls with a mouse or touch. Keep the playing area visible while using these controls. Return to the rules if the result is unexpected.
Try this example
Tapping the centre changes five cells. Tapping a corner changes three. Diagonal neighbours are not affected. Compare this with the rule that governs the move. Choose a deliberate next step.
Pay attention to this rule
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.
