Fandango is gearing up for the March 23 opening of feature film The Hunger Games by giving away 10 promotional mockingjay pins via the movie’s Facebook page.

For those unfamiliar with The Hunger Games, Mockingjay is the title of the third book in the three-book series, and main character Katniss Everdeen wears a pin depicting a bird called a mockingjay throughout much of the story.

Facebook users who like Fandango’s Hunger Games movie guide are eligible to enter by posting one comment apiece to this entry naming one of the three books in The Hunger Games series.

The promotion runs through Sunday, when Fandango will randomly select 10 winners to receive mockingjay pins.
