Lights Out: how a round works
Use a short break to learn the rhythm 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. Keep the game area visible while you use its controls. Choose a comfortable screen position before beginning. Choose a clear next step rather than rushing through the instructions.
Practice beyond the first move
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.
The objective of a round
Turn every light off. Every supplied starting state is made by valid flips from an all-off board and is therefore solvable. Use the instructions to see which actions move you towards it. Follow this game’s rules rather than another version’s.
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.
Making selections and moves
Use the on-screen controls with a mouse or touch. Use the control method described here for this activity. Look at the feedback after the action.
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.
Check this before moving on
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. Locate the buttons and input area before beginning a long round. Use the on-screen labels to avoid an accidental restart.
