To see the lightning bolt, you have to solve the jigsaw puzzle. Some of the jigsaw pieces maybe upside down. To turn one over, hold the “T” key and left-click your mouse. Also keep in mind that pieces can hide behind each other, so move the pieces (or your partially completed puzzle) around the board to find those stray pieces.
