A useful example
Tapping the centre changes five cells. Tapping a corner changes three. Diagonal neighbours are not affected. Your next round may have a different position, so inspect it before acting. Notice the change in the playing area.
Watch out for this
An unlit tile can still be tapped; it may be necessary to solve the board. Compare the situation with the worked example. Compare the worked example with your own position. Use the reasoning, not an answer copied from a different board.
