If you’re visiting Amsterdam and looking for something a little different from the usual canal cruise or museum visit, Operation 45: An Adventure in Diamonds might just surprise you. This interactive tour is designed to blend history, puzzles, and city exploration into a fun, engaging experience that’s perfect for curious travelers. It promises to reveal a lesser-known chapter of Amsterdam’s WWII past while giving you a chance to challenge yourself and your travel companions.
What really stands out about this experience is its personalized approach — you can create your own schedule and go at your own pace, making it flexible for different groups. Plus, the fact that it’s just for your own private group means no worries about strangers in your puzzle-solving adventure. That’s a big plus for those who prefer a more intimate, tailored experience. We also appreciate how affordable it is, especially given the quality and uniqueness of the journey.
On the flip side, a potential consideration might be the reliance on good weather, as the experience takes place outdoors around Amsterdam’s streets. If rain or poor weather is forecasted, it’s good to be prepared or consider rescheduling. This tour is especially suited for those interested in history, puzzles, or simply someone who wants to see the city from a different angle without feeling like they’re just ticking off a list of sights.
In short, Operation 45 is best for travelers who enjoy a hands-on exploration, aren’t afraid to think on their feet, and love discovering lesser-known stories from a city’s past. It’s a creative and interactive way to spend a couple of hours in Amsterdam, with enough flexibility and privacy to fit different travel styles.

Exploring Operation 45: What It’s All About
This tour isn’t your typical city sightseeing. Instead, it offers an engaging walk-and-play experience centered around Amsterdam’s WWII history, specifically the story of industrial diamonds and resistance efforts during the Nazi invasion. The tour starts at Mystery City Games on Zwanenburgwal 178, and it takes about 2 hours—a nice chunk of time to dive into history without feeling rushed.
The storyline is fascinating: on May 10, 1940, when the Netherlands was invaded, a secret mission was launched to keep the city’s diamonds out of Nazi hands. Then, after the end of the war, the final mystery is to uncover what happened to those priceless diamonds. The game unfolds as you walk through the city, stopping at interesting buildings and monuments, while solving puzzles that reveal the story of resistance and survival.
What makes this experience particularly appealing is the interactive nature. Instead of passively listening to a guide, you and your group will actively participate through puzzles and clues, making history feel alive and personal. The possibility of splitting into competing teams for six or more players adds a fun, competitive twist — or you can keep it a cooperative effort if that’s more your style.
The tour emphasizes learning true stories from Amsterdam’s past, making it both educational and entertaining. It’s great for those who love a bit of mystery and want to connect with the city’s history on a more personal level. The fact that it’s private for your group means you won’t be distracted by strangers and can focus on your own adventure.
