What counts as success
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.
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.
Using the playing area
Use the on-screen controls with a mouse or touch. On a smaller screen, keep the active part of the board within view. Return to the rules if the result is unexpected.
Follow the example
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. Keep the controls nearby.
Pay attention to this rule
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. Locate the buttons and input area before beginning a long round. Use the on-screen labels to avoid an accidental restart.
