The Story:

WWI has just broken out. As soldiers are leaving Paris in taxis headed to the battlefield, you have a special mission: find the secret weapon left behind by France’s most famous scientist, Marie Curie. Do you have what it takes? Explore the city and solve puzzles in this outdoor escape game to find out!

What is it?

Mystery City Games are a mix between a treasure hunt,  escape room, and walking tour. It’s a bit like the Da Vinci Code or National Treasure – it’s about using clues hidden in the architecture of the city to solve a mystery. It’s an outdoor escape room in Paris like no other and should definitely be included in your ‘top 10 things to do in Paris’!. No app or phone is needed – we think treasure hunts are more fun with real treasure maps, locks, and beautiful pieces. 

How It Works:

  • You will meet the Game Master at Hint Hunt in the Marais to pick up a backpack containing all of the materials that you need to play: treasure maps, boxes, locks, and beautiful tools
  • Follow an ancient treasure map as you walk through Paris city center discovering must-see city sites and monuments
  • Solve puzzles while exploring Paris’ top attractions and having fun with your friends or family on a holiday, bachelorette party, or weekend out. If you only have one day in Paris, this is the way to see it!
  • Learn true stories from the city’s history
