Practice beyond the first move
Choose one rule to keep in mind for this round. Apply it consistently rather than guessing what another version might allow. Use the example to check your reasoning.
Understand the aim
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.
The playing sequence
- 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.
Getting comfortable with the controls
Use the on-screen controls with a mouse or touch. A careful first action helps you become familiar with the layout. Check any mode label before starting.
An example to follow
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. Consider the next action carefully.
Notice this detail
An unlit tile can still be tapped; it may be necessary to solve the board. Compare the situation with the worked example. Locate the buttons and input area before beginning a long round. Use the on-screen labels to avoid an accidental restart.
