What Makes This a Great Family-Friendly Activity?
Mystery City Games offers a unique outdoor adventure that transforms the streets of Paris into a giant puzzle. Part treasure hunt, part escape room, and part walking tour, this experience invites players to discover the city in a completely different way.
In our Paris game, Marie Curie’s Secret Weapon X, players follow a trail of clues left by the famous scientist at the start of World War I. By decoding messages, solving puzzles hidden in the architecture, and uncovering secret connections between historic locations, teams work their way through the city to reveal the final secret.
Each team receives a backpack filled with beautiful game materials including treasure maps, puzzle books, and mysterious tools. Using these props, players visit several locations in central Paris where they must work together to solve challenges and unlock the next step of the adventure.
The experience blends storytelling, teamwork, and exploration. Along the way, players discover fascinating pieces of Parisian history while navigating charming streets, historic squares, and iconic landmarks.
Mystery City Games is designed for friends, families, tourists, and corporate groups looking for a fun and interactive way to experience the city. The game is private for your group and can be played at your own pace.
Unlike most city games, this is not an app-based experience. Everything is physical and tactile, creating a more immersive and memorable adventure.
