Hunt down Magnus and the stolen formulas in Leiden on foot, from the Stadhuisplein past the Vismarkt to the Pieterskerk.

A theft, a man called Magnus, and a city he thinks he can disappear into. Leiden is where you start looking.

Think of it as a secret agent game played on real streets. The Syndicate runs on your own phone through the Loquiz app, with Leiden as the board: stand somewhere that matters and the location gives up a riddle, a cipher or a photograph to take. Your group divides into characters, each with a job in the mission, so the case gets solved by all of you rather than by one person.

You will pass Vismarkt, Hooglandse Kerk and Dullenbrug. The case does not pause for the walking, and nothing you need is handed to you on screen — you have to be standing there and looking.

You also reach Hartebrugkerk and Pieterskerk. At some stage the group stops seeing streets and starts seeing evidence.

The Outdoor Escape Game Version, on the Streets of Leiden

Take the part of an escape room you actually enjoy — the ciphers, the logic, the moment it clicks — and put it on the streets of Leiden. You cover 3 to 4 km on foot over two hours, nobody is locked in anywhere, and no facilitator is rationing hints or resetting anything for the next group. Stuck on something? Keep walking with it.

A Team Building Escape Game You Can Organise in Leiden Today

This one takes about a minute to organise: book a date, and let the teams start when they are ready. There is nothing to book a room for, nobody to hire and no schedule to hold everyone to — the case, the route and the puzzles are already built around Leiden, and it runs about two hours over 3 to 4 km on foot. One ticket covers a group of two to five people on a single phone for €19.95, so a department of twenty is four tickets and four teams racing the same case. If you have been asked for company outing ideas and would rather not book another restaurant, this is the version where somebody else did the work.

A Heist Game for Groups of Almost Any Shape in Leiden

Teams. A team building escape game that needs no facilitator, no room booking and no scheduled start. Buy one ticket per five people, send the teams into Leiden on the same case, and compare who cracked what. Running several groups at once is what turns it into a competition, and it is the reason this works as a company outing rather than just an afternoon out.

Friends. Everyone in the group takes a character with a job to do in the mission, which is the part that stops one person doing all the thinking. A heist plot, a city to search and no host watching the clock.

Couples and pairs. The whole case fits on one phone between two of you at €19.95. Nobody to tag along with, nothing to catch, no guide — you decide how fast it goes and where it pauses.

Families. It works from about age eight, and 3 to 4 km is a walk children manage without trouble. They are usually the ones who spot the detail on the wall that the adults walked past, and the code-breaking is the part you do together.

Frequently Asked Questions

How does the Syndicate city escape game work?

You book a date, get a link by email and download the Loquiz app. At the starting point in Leiden you open the game on your phone. It knows where you are, and each location holds a riddle, a code or a photo task. Solve one and the next location unlocks, until you have enough to catch Magnus.

What is the story?

A set of formulas has been stolen and Magnus is the one carrying them. Your job is to reach him first. Each player takes a character with a specific role in the operation, so it plays as a role-playing game and not as a sequence of riddles.

Is this an escape room?

It is not. Nothing is locked, nobody is hosting, and there is no room to be let out of — it is an outdoor escape game on real streets. The thinking will feel familiar to anyone who does escape rooms; the walls are simply gone.

How long does it take?

It runs about two hours, covering 3 to 4 km on foot. There is no time limit and no fixed start — you pick a date when booking and then begin whenever suits you on that date, so a slow group simply takes longer.

How many people can play on one ticket?

One ticket covers a group of two to five people playing on one device, at €19.95 in total. Groups larger than five buy a second ticket, which also lets them play against each other.

Is it hard?

The difficulty is intermediate. The puzzles need looking and lateral thinking rather than local knowledge, and nothing is so obscure that a group gets stuck for good.

Is it suitable for children?

Eight and over is the usual guide. Nothing about the 3 to 4 km is demanding for them, they tend to win the photo tasks outright, and they notice things on walls that adults have walked past twice.

Do we need to book a time?

You pick a date when booking, then you begin whenever you like. There is no meeting point, no guide and no group to join.

What happens if it rains?

You decide when to play and you can pause whenever you like. If a shower comes over, step inside somewhere, wait it out and pick up where you left off — nothing is counting down while you wait.

What size group does it work with?

Two to five people share one phone on a single ticket, so two is the smallest group. If you would rather have a murder to solve or a scavenger hunt than a heist, the other city games in Leiden cover that.

    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!
