Something to practise
Watch the feedback after an action. A message can explain whether the input was accepted or whether a rule needs attention. Keep the objective visible.
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. Read that aim before choosing your first action. Start with a deliberate move.
The order of 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.
How to use the controls
Use the on-screen controls with a mouse or touch. Keep the playing area visible while using these controls. Return to the rules if the result is unexpected.
An example to follow
Tapping the centre changes five cells. Tapping a corner changes three. Diagonal neighbours are not affected. Apply the same reasoning to the position in your own round. Verify the rule before continuing.
Keep this in mind
An unlit tile can still be tapped; it may be necessary to solve the board. Take a moment to reassess the position before continuing. Before your first action, say what you are trying to achieve. Then compare the result with the goal.
