How to play Lights Out
Make Lights Out your next activity in the game library. 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. Treat the first round as a chance to learn the controls. Check the relevant rule before repeating a move.
One thing to notice as you play
Watch the feedback after an action. A message can explain whether the input was accepted or whether a rule needs attention. Notice the feedback after each input.
The challenge in front of you
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. Take a moment to understand the current position.
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.
Choosing and moving on screen
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.
Learn from a sample situation
Tapping the centre changes five cells. Tapping a corner changes three. Diagonal neighbours are not affected. Use the example as a guide rather than a substitute for reading your board. Verify the rule before continuing.
A mistake to avoid
An unlit tile can still be tapped; it may be necessary to solve the board. Check the rule before repeating the action. Before your first action, say what you are trying to achieve. Then compare the result with the goal.
