Lights Out: from controls to your first round
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. Choose a comfortable screen position before beginning. Choose a clear next step rather than rushing through the instructions.
Bring this focus to a round
Choose one rule to keep in mind for this round. Apply it consistently rather than guessing what another version might allow. Notice the feedback after each input.
The goal to keep in mind
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. 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.
How to use the controls
Use the on-screen controls with a mouse or touch. On a smaller screen, keep the active part of the board within view. Use one clear input at a time.
An example before you play
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. Verify the rule before continuing.
A useful caution
An unlit tile can still be tapped; it may be necessary to solve the board. Compare the situation with the worked example. After a move, check what changed. Decide which rule explains the new state before acting again.
