Introducing the New Jack Stalwart App

Just in time for summer!

Jack Stalwart App


Eight priceless treasures have been stolen in eight countries around the world. Your mission is to identify and find each of these treasures by solving coded messages, cryptic riddles, tricky tile puzzles and dastardly search and finds. Each time you find a treasure, you’ll earn a passport stamp. Collect eight passport stamps, and you’ll receive a free Jack Stalwart prize download at the end. The ultimate prize is one of three GPF Gadget Trading Cards found only in the app!

The Secret Agent Jack Stalwart app is based on the award-winning series of chapter books created by Elizabeth Singer Hunt.  For more information about the series, visit www.elizabethsingerhunt.com.
