THE PLAYBOOK · BXBZYS
Making your first moves in 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. Keep the game area visible while you use its controls. Begin with the solo mode shown on the page. Check the relevant rule before repeating a move.
One thing to notice as you play
After a move, check what changed. Decide which rule explains the new state before acting again. Make the next step deliberately.
Aim for this result
Turn every light off. Every supplied starting state is made by valid flips from an all-off board and is therefore solvable. An attractive position is not enough unless the goal is met. Try to explain the aim in your own words.
A walkthrough of the rules
- 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.
Keyboard and screen controls
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 to follow
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. Keep the game’s format in mind.
A mistake to avoid
An unlit tile can still be tapped; it may be necessary to solve the board. Read the feedback to see why an action did not have the expected result. Watch the feedback after an action. A message can explain whether the input was accepted or whether a rule needs attention.
