Based on the award-winning 'Secret Agent Jack Stalwart' children's book series.

In the app, children become 'secret agents' on a mission (as Jack, Kate or an alter ago) to try and find the location of eight stolen treasures and the villains behind each theft.

Each time they rescue a treasure, they earn a passport stamp. After collecting all eight, they win a downloadable and collectible prize from the series.

Like the books, the 'Secret Agent Jack Stalwart' app was designed to educate children about world culture and geography. The 14-book series has won awards, been named a 'must read' for boys by the British Education Secretary, serialized by BBC Radio, and featured on Virgin Atlantic Airways' international flights. Millions of copies have sold, and it's been translated into multiple languages. ​​

Puzzle problem

My son got to Egypt and it crashed on the puzzles. He really enjoyed the game. Four pieces of the puzzle are the same therefore he can't properly finish it.

Got this app for my grandson Morgan! He can't get enough of Jack Stalwart. Loves his books, website and app.

Love the App. Kept the kids interested on a long car ride while helping them learn something. Not just another arcade game, but equally does not make kids feel like they are in school. Nice.
