A detective game through the fortified town of Brielle: start at the Arsenaal and follow the trail out to the ramparts.
The Balthasar case is open in Brielle, and it stays open until somebody walks the route and reads it properly.
This is a self-guided murder mystery game you play outdoors, at your own pace, with Brielle for a board. Your phone carries the case file and the city carries the evidence. Clues to gather, digital characters to question, codes to break and a name to give at the end - a detective game with no host at a meeting point, no timetable and no group to keep up with.
The case takes you past Sint-Catharijnekerk, Historisch Museum Den Briel and Markt.
The Route Through Brielle
Add Kaaipoort and Langepoort to that. The whole thing measures 3 to 4 km, which is a comfortable afternoon rather than a hike.
How the Murder Mystery Game Works in Brielle
The story arrives as you move. Every location holds something to work out, and the digital characters you meet each know one piece of what happened to Balthasar. Reckon on 1.5 to 2 hours and 3 to 4 km, but there is no clock: break for lunch and pick it up afterwards. The reasoning runs the way it does in a Sherlock Holmes story: small observations first, the accusation last.
Friends, Families and Colleagues in Brielle
With friends. Four people, one phone, one case. Somebody will back the wrong suspect early and refuse to let it go, and that is the part everyone remembers.
With your team. Buy a ticket per four, put every team on the same murder, compare the answers over lunch. Nothing to hire and nobody to brief, so a company outing in Brielle survives people turning up late.
With kids. Eight years old is about the floor. The distance is not the problem it sounds like, the photo tasks are where children beat adults outright, and the codes end up being solved by the whole family at once.
Frequently Asked Questions
How does the murder mystery game work?
You play it through the Loquiz app on your own phone. It opens in Brielle, the story moves with you, and every stop holds a puzzle, a code or a photo task standing between you and the next piece.
How long does it take?
Set aside an afternoon. The case itself takes 1.5 to 2 hours across 3 to 4 km, but nothing counts down and nothing shuts, so the breaks are free.
How many people can play on one ticket?
One ticket covers one to four players on a single device, €19.95 in total. Bigger groups buy one ticket per four and race each other through the same murder.
Do we need to book a time?
You pick a date, not a time slot. Start at nine or start at four; nothing in Brielle is waiting on you and no guide is standing anywhere.
Is it suitable for children?
Eight and up handle it well. Nothing along the way is beyond them, and more often than you would expect it is the youngest player who notices the detail that decides the case.
What happens if it rains?
Nothing forces you to keep walking. Duck into a cafe, let it pass and carry on when you feel like it - there is no time limit on any part of this.
Is this a detective game or a walking tour of Brielle?
You get the walk either way. The difference is that you arrive at each place with a question, and a question makes people look at a building far harder than a plaque ever does.
What else is there to do in Brielle?
You can play more than one: other city games in Brielle use the same streets for another case, and the rest of the Netherlands is one list away.

I had a fantastic experience with CityGame! The concept is creative, engaging, and a great way to explore a city in a completely new way. The games are well-designed, combining puzzles, storytelling, and adventure so you’re constantly discovering something interesting around every corner. What I especially love is how CityGame turns a normal walk through the city into an interactive experience. It’s perfect for friends, families, or team outings, and it makes sightseeing much more exciting than the usual tours. Everything was easy to use, the challenges were fun and clever, and it really encouraged us to look closer at the city and its hidden details. Highly recommended if you’re looking for a unique and memorable way to explore!

This is an interesting way to conduct a self-guided Amsterdam city tour. It used the GPS on your phone to guide you to stops on a route. There are mini quizzes once you arrive at the stops on the path. The quizzes draw your attention to features in front of you or to a brief history of the place. In many cases, we visited a spot that would not have been obvious as a regular passer by. The tour as a whole was interesting to us as newcomers, but I would have liked more information on many locations we visited - a few links outside of the app for each place would have been helpful. Beyond that, the interface was a bit clunky and sometimes awkward to navigate. We definitely don't regret trying this out and feel like we got our money's worth on the experience.

This was a fun game! It had a few challenges which was good and surprises. It got me to go around and explore Queenstown, New Zealand. I got to places in Queenstown, New Zealand I hadn’t been to before while on holiday here. Thank you for that and it gave a feel what it would be like to be the actual Sherlock Holmes!
