Step into the story
A murder in the city
You are Sherlock Holmes, and Watson is at your side. Balthazar has been found dead, four people had a reason, and only one of them did it.
- 1.5–2 hours
- 1–4 players per team
It beginsAnd we need you to find out who killed Balthazar.
It goes wrongYou ring the bell. Nobody opens the door but you catch a shadow moving through the house! Somebody is home!
Your moveWalk the city, question the witnesses, gather the evidence and name the killer. Good luck, and have fun.
Every player takes on one of these roles.
The Reasoner
The Lookout
The Photographer
The Casebook
Somebody killed Balthasar in Thessaloniki. The evidence never left the neighbourhood, which is where you come in.
A self-guided detective game, played on foot in Thessaloniki rather than around a table. The app keeps the case file, the streets keep the proof, and the murder mystery only moves when you do. There is no guide, no start time and no group - which is exactly the appeal.
The case takes you past Church of St. Demetrios, Λευκός Πύργος της Θεσσαλονίκης and Μονή Βλατάδων.
The Walk Through Thessaloniki
Επταπύργιο and Agia Sofia are on the route as well. Anyone keeping decent notes will find they only have to confirm there what they already suspect.
Had great fun playing secrets of Haarlem!
Playing the Detective Game in Thessaloniki
You walk and the case reaches you in pieces. Digital characters wait along the way, each with part of the truth and each wanting something first: a puzzle, a code, a photograph. Whatever you solve crosses a name off the list. Allow 1.5 to 2 hours over 3 to 4 km, though nobody is timing you - stop for an hour and the case waits. The habit is the one the Sherlock Holmes stories are built on: notice the thing nobody else bothered to look at, then say out loud what it means.
For Families, Friends and Teams in Thessaloniki
With friends. Four of you on one phone and everybody gets a say. Somebody always commits to a theory early, loudly, and wrongly - that is half of what you will talk about afterwards.
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 Thessaloniki survives people turning up late.
With kids. Eight and up manage it comfortably. Children are usually quickest on the photo tasks, and teenagers who have stopped being impressed by old buildings get competitive about the puzzles instead.
Before You Book
How does the murder mystery game work?
It runs in the browser on your own phone, no app download needed. Open it at the starting point in Thessaloniki, and from there the case comes to you: someone to question at each location, something to solve before they talk, and a name to hand in at the end.
How long does it take?
Between one and a half and two hours for most groups, across 3 to 4 km. Slower is free: nothing is timed and nothing expires while you are having lunch.
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. Start at nine or start at four; nothing in Thessaloniki is waiting on you and no guide is standing anywhere.
Is it suitable for children?
Yes, from about eight. The difficulty is easy, the walking is gentle, and children tend to be the fastest in the group at the photo tasks.
What happens if it rains?
Rain is an interruption, not a problem: you choose the moment to start and you can stop as long as you like. Plenty of groups split the case over a morning and an afternoon.
Is this a detective game or a walking tour of Thessaloniki?
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 Thessaloniki?
You can play more than one: other city games in Thessaloniki use the same streets for another case, and the rest of Greece is one list away.

Wir (Mein Mann, unsere 9-jährige Tochter und ich) haben heute ganz spontan das Spiel "Moordmysterie Düsseldorf" gebucht und gespielt. Die Buchung verlief schnell und reibungslos. Es hat super viel Spaß gemacht! Die Story, die Rätsel, das Konzept, die Route, die Gestaltung der App... richtig gut!!! Das Spiel würde ich vor allem Familien mit Kindern empfehlen. Für Erwachsene waren die Rätsel (meiner Meinung nach) zu einfach. Aber trotzdem wegen der schönen Route durch Düsseldorf, der Story, den lustigen Anweisungen zwischendurch eine schöne Aktion, die man zusammen machen kann.

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.
