Lights Out: a guide for your next round
Start Lights Out by looking at the playing area and its controls. Turn every light off. Every supplied starting state is made by valid flips from an all-off board and is therefore solvable. Keep the game area visible while you use its controls. Check the rule that explains your first action. Use the example below to understand a decision.
A small practice goal
When a decision goes wrong, compare it with the common mistake described below. Start again only when you intend to leave the current round. 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. Review the board or playing area as it changes.
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 interact with the game
Use the on-screen controls with a mouse or touch. On a smaller screen, keep the active part of the board within view. Check any mode label before starting.
A useful example
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. Read the matching step again.
Watch out for this
An unlit tile can still be tapped; it may be necessary to solve the board. Take a moment to reassess the position before continuing. Compare the worked example with your own position. Use the reasoning, not an answer copied from a different board.
