Lights Out: instructions and practice
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. Use the example below to understand a decision. Read the objective before making your first input. Keep the game area visible while you use its controls.
Practice with a purpose
Take enough time to read a new position. If a game has a timer, learn its controls first rather than searching for them during the round. 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. An attractive position is not enough unless the goal is met. Return to the instructions when a step is unclear.
From the start of a round
- 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.
Input guidance
Use the on-screen controls with a mouse or touch. Read a button’s label before selecting it. A new-round button replaces the current round.
A closer look at one example
Tapping the centre changes five cells. Tapping a corner changes three. Diagonal neighbours are not affected. Your next round may have a different position, so inspect it before acting. Keep the controls nearby.
Where a round can go wrong
An unlit tile can still be tapped; it may be necessary to solve the board. Take a moment to reassess the position before continuing. 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.
