Mastermind is a short story about a little girl named Ivy reflecting on her favorite game she's ever played, 'Mastermind,' during Taylor Swift's The Eras Tour. As she reflects back on her time following the tour, Ivy recounts funny inside jokes, frustrations, and game strategy while playing Mastermind, but more importantly shares tales of the strong sense of community she developed with fellow Swifties throughout The Eras Tour. Mastermind was written and illustrated by Betsy Sedlak, who created all of the Eras outfit drawings in the Swift Alert app, and was edited by Kyle Mumma, Swift Alert's creator. The tale is a thank you to our 1 million + Mastermind players around the world, and hopefully can serve as a keepsake to reflect on the most fun we've ever had (we'd do it over, and over, and over again). We've had the time of our lives with you!
