Play Lights Out with the rules at hand
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. Check the relevant rule before repeating a move. Choose a comfortable screen position before beginning. Look at what changes after your first action.
A small practice goal
Keep the stated aim separate from side details such as animation or appearance. Progress is measured by the game’s own completion or scoring rules. Use the example to check your reasoning.
Your goal
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. Notice how the game responds to your input.
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.
The controls to know
Use the on-screen controls with a mouse or touch. Read a button’s label before selecting it. Make sure you are interacting with the game rather than the surrounding page.
Put the rules into context
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. Look for the relevant detail.
A useful caution
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. When a decision goes wrong, compare it with the common mistake described below. Start again only when you intend to leave the current round.
