The History of Mystery City

Dear Visitor,

It was a rainy night, many years ago, when a night at a Pub Quiz planted the seed that would become our many year obsession. After a few drinks and a near-loss, we began to talk about a better way to explore the city. The original idea was to create a historical adventure. We quickly got to work, finding stories, creating puzzles and two years later... we had created a puzzle game that people loved to play!

Our mission is to show people another way to explore. To take them away from their phones and their guided tours and give them the tools they need to see the city in detail. Along the way, we'll teach a little bit of what makes our city so fantastic!

Our puzzles are challenging, fun, and historical. They're perfect for friends, families, or colleagues. You can learn more about how it works here.

Love and puzzles,

A Secret Sender

Who are we

We are Geert Benjamin Sillevis and Emilie Mendes de Leon, a couple of friends who wanted to play the Da Vinci Code in real life. So we created treasure hunts for grown-ups: well researched, historically accurate games that ask players to solve puzzles around a real event or phenomenon that happened in the city.

We love spy stuff, finding gable stones, and spending too much time in the city archive. These are games that we'd want to play if we were visitors or long-time residents - we hope that you feel the same!
