Read before your next round of Lights Out
Bring your attention to one round 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. Look at what changes after your first action. Choose a comfortable screen position before beginning. Choose a clear next step rather than rushing through the instructions.
Try a more deliberate round
Read one step at a time and try it on the playing area. Match the instruction to the control you use. Use the example to check your reasoning.
What the game asks you to do
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.
The order of play
- 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.
The controls to know
Use the on-screen controls with a mouse or touch. On a smaller screen, keep the active part of the board within view. A new-round button replaces the current round.
An example before you play
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. Check the stated objective.
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. Locate the buttons and input area before beginning a long round. Use the on-screen labels to avoid an accidental restart.
