One thing to notice as you play

Before your first action, say what you are trying to achieve. Then compare the result with the goal. Make the next step deliberately.

Your goal

Turn every light off. Every supplied starting state is made by valid flips from an all-off board and is therefore solvable. An attractive position is not enough unless the goal is met. Check the rules when you are unsure.

Follow these playing steps

  1. Select a light or an unlit tile.
  2. The selected tile and its orthogonal neighbours switch state.
  3. Plan flips so that previously cleared rows stay cleared.
  4. Use Undo to try another approach.

Input guidance

Use the on-screen controls with a mouse or touch. A careful first action helps you become familiar with the layout. Return to the rules if the result is unexpected.

Try this 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. Look for the relevant detail.

A mistake to avoid

An unlit tile can still be tapped; it may be necessary to solve the board. Read the feedback to see why an action did not have the expected result. Take enough time to read a new position. If a game has a timer, learn its controls first rather than searching for them during the round.
