Lights Out: from controls to your first round
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. Use the example below to understand a decision. Compare the starting position with the example in the Guide. Choose a clear next step rather than rushing through the instructions.
Something to practise
Watch the feedback after an action. A message can explain whether the input was accepted or whether a rule needs attention. Refer to the controls when needed.
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. Follow this game’s rules rather than another version’s.
The steps to play
- 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.
Controls
Use the on-screen controls with a mouse or touch. A careful first action helps you become familiar with the layout. Use one clear input at a time.
Follow the example
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. Consider the next action carefully.
Where a round can go wrong
An unlit tile can still be tapped; it may be necessary to solve the board. A different version of the game may use a different rule. After a move, check what changed. Decide which rule explains the new state before acting again.
