Lights Out: from controls to your first round
Take a moment with Lights Out before moving to another game. 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. Choose a comfortable screen position before beginning. Choose a clear next step rather than rushing through the instructions.
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.
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. Read that aim before choosing your first action. The example below illustrates a decision.
Work through the instructions
- 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. Read a button’s label before selecting it. Check any mode label before starting.
See how the rules apply
Tapping the centre changes five cells. Tapping a corner changes three. Diagonal neighbours are not affected. Focus on why the action is allowed, not only its outcome. Notice the change in the playing area.
Keep this in mind
An unlit tile can still be tapped; it may be necessary to solve the board. Check the rule before repeating the action. Choose one rule to keep in mind for this round. Apply it consistently rather than guessing what another version might allow.
