Groningen Self Guided Sherlock Holmes Murder Mystery Game
The most interesting feature here is that Groningen becomes your crime scene. You follow a Sherlock Holmes story from your phone, searching for clues, solving codes, and working through the murder of Balthasar at your own pace.
I like the freedom to start anytime on your selected date, and I like the private format for up to four people per ticket. The puzzles are rated easy, so families can join in without needing expert detective skills.
The main concern is your phone battery. One player reported losing most of the charge within the first 20 minutes. Bring a well-charged device, and remember that the Loquiz app lets you return later through Laatste sessie hervatten, or Continue Last Session.
Key points to know before you play

- Start at Grote Markt: The game begins in Groningen’s main square and ends back at the same meeting point.
- One ticket covers up to four people: Larger groups can buy additional tickets and play in separate groups.
- Play whenever you choose: Pick any start time on your selected date rather than joining a fixed departure.
- Sherlock Holmes story: Your case is the murder of Balthasar, told through digital characters, clues, codes, and plot twists.
- Easy difficulty: The puzzles suit families with children as well as adults who enjoy casual detective games.
- Plan for battery use: The game runs on your smartphone through the Loquiz app, so a full charge matters.
A detective case that uses Groningen as its playing field

This is not a guided walk with a local expert explaining Groningen’s monuments. It is a self-guided mystery game that uses the city as the setting for a Sherlock Holmes story.
Your mission is to investigate the murder of Balthasar. The plot unfolds through the Loquiz app, which gives you instructions, story details, digital characters, puzzles, and tasks. You move through the city while the phone guides the next part of the case.
That format changes how you experience the center. Instead of simply following a guide from one sight to another, you watch for clues and discuss what you see with your group. The city becomes a practical game board. Still, keep your expectations clear: the activity does not include background information about Groningen’s highlights or a guide who interprets the streets for you.
The game lasts about two hours. That is long enough for a proper outing, but short enough to fit around a meal, museum visit, or other plans in Groningen. Since there is no fixed departure time, you can choose a cooler morning, a quiet afternoon, or an evening slot that suits your day.

Starting at Grote Markt in Groningen
The meeting point is Grote Markt, the central square in Groningen. This is a useful starting place because it gives your group an easy location to find and a clear point to gather before opening the game.
After booking, check your email for the instructions. You will need to download the Loquiz app and use your smartphone or another compatible device to play. The exact process is designed to be handled without a guide, so take a few minutes before starting to make sure the app is ready.
The game ends back at Grote Markt. That return to the starting point makes planning simple. You do not need to arrange transport from a distant finish, and you can leave your bags or onward plans based on the same central location.
Because the activity is self-guided, you should allow a little time to get your bearings before the first puzzle. Gather your group, charge the phone, read the instructions, and decide who will hold the device. Small choices like these can make the game easier to manage.
How the two-hour mystery unfolds

The story begins with the murder of Balthasar. From there, you follow a chain of clues and challenges through the app.
You might be asked to read information from a digital character, work out a code, or complete a photo task. The supplied details do not identify every location or puzzle in advance, which is part of the point. You discover the sequence as the case develops rather than being handed a full route before you begin.
The game is built around story-driven play, not a list of sightseeing stops. Each solved puzzle moves the story forward and brings you closer to the truth. If your group enjoys discussing possibilities, the pauses between challenges become part of the fun. One person may spot a clue while another sees the pattern in a code.
The photo tasks add a physical and social element. They give you something active to do instead of keeping your eyes on the screen for the entire two hours. For families, this can help younger players stay involved. For colleagues or friends, it gives the group a reason to cooperate rather than letting one person solve everything alone.
The plot includes twists, so you should expect the case to change direction. The difficulty is described as easy, which makes the game approachable. It also means experienced puzzle fans may find the challenge fairly light. If you want a very demanding escape-room style test, this may feel more like a relaxed city activity.
Playing alone, with family, or in a small team

The game works for one person, but the group format is likely the better choice. One ticket covers up to four people using one device. That keeps the cost low and lets everyone follow the same story.
With four people, you can divide the work naturally. One person can read the app, another can search for clues, and the others can test possible answers or handle photo tasks. The game does not require a separate device for each person, which helps keep the group focused.
For families, the easy difficulty is a real advantage. Children can take part in the search and photo challenges without needing to solve every code alone. Adults may need to guide the group through the story, but the activity is not presented as an advanced puzzle competition.
Friends and colleagues can use the game as a casual team activity. It asks you to communicate, but it does not require a formal team-building program or a guide standing over you. The private format also means your group can discuss clues without sharing the experience with strangers.
Solo play offers the most control, but it also places every task on one person. You must read the story, operate the app, solve puzzles, and complete the photo tasks yourself. The easy difficulty makes that possible, though some of the social fun naturally disappears.
Larger groups can buy multiple tickets and play in separate groups. That allows several teams to tackle the same case, though each group will need its own ticket and device setup.

What the Loquiz app adds, and what it demands

The app is the engine of the experience. It delivers the instructions, story, characters, puzzles, and tasks directly to your phone.
That arrangement gives you flexibility. You are not waiting for a guide, and you can begin at any time on your chosen date. If your plans change during the day, the lack of a fixed start time is useful.
The tradeoff is that the quality of your outing depends partly on your device. You need to bring your own smartphone or another device, and the game is not supplied with a phone. Keep the screen visible, make sure the app is installed, and check that the battery is in good shape.
The battery warning deserves attention. A player reported that the phone had used about 70 percent of its charge in the first 20 minutes, making it impossible to finish at that time. The support response noted that the game can be resumed later in the app through the Continue Last Session option.
That does not remove the problem, but it does make a pause possible. I would start with a fully charged phone and, if you have one, carry a portable charger. If several people have the app or access to the game, that may also give you a backup if one phone runs low.
The app-based design is best for people who are comfortable following digital instructions. If you prefer a human guide, printed clues, or a tour with spoken explanations, this activity will not provide those things.
The value of $31.07 per group
The listed price is $31.07 per group of up to four people. At the full four-person capacity, that works out to roughly $7.77 per person.
That is a reasonable price for a two-hour private activity, especially for a family or group of friends. You are paying for a shared story, puzzles, photo tasks, and the freedom to choose your starting time. There is no guide fee to add, and the same ticket covers the whole group within the four-person limit.
The value drops if you play alone, since one person pays the full group price. Even then, the flexible schedule and private format may matter if you want an activity that fits between other plans.
Remember that the price does not include a smartphone, transport, food, or a guide. It also does not provide a formal explanation of Groningen’s major sights. You are buying a game rather than a conventional city tour.
For a group that enjoys solving mysteries, the cost is easier to justify. For someone mainly interested in Groningen’s architecture, local stories, or museum collections, a guided walking tour may offer more useful information.
The city setting, without a traditional city tour

The activity uses Groningen as the place where the case unfolds, but it is not designed to teach you the city in depth.
You will move through public areas and use the scenery around you as part of the game. That can make familiar streets feel different. You may pay closer attention to signs, buildings, corners, and public spaces because the story has given you a reason to look.
Still, do not book this expecting a guide to point out major landmarks or explain local history. The experience is focused on the murder mystery. Any connection with the city comes through the route, the setting, and the clues rather than through commentary.
That distinction is important when comparing options. I would choose this for play, teamwork, and a change of pace. I would choose a guided walk if my main goal were to understand Groningen’s past or see its highlights with expert context.
Timing, accessibility, and practical planning
The game takes about two hours, and you choose the start time on your selected date. Since the activity begins and ends at Grote Markt, it is simple to place within a day in Groningen.
The activity is near public transportation, and service animals are allowed. Most people can participate. No special physical requirements are provided, so you should use your own judgment about comfort with walking and phone-based tasks.
Wear practical shoes and keep your phone easy to reach. The exact route and amount of walking are not specified, so do not assume that every challenge takes place in one small section of the square.
You can cancel for a full refund if you do so at least 24 hours before the start time. Changes or cancellations within 24 hours are not accepted for a refund. The cut-off follows local Groningen time.
The activity is private, meaning only your own group participates. That is useful if you want to keep the mystery within your party and move at your own pace.
Who should book this Groningen mystery game?
I would recommend it to friends looking for a light puzzle outing, families who want an activity that involves children, and colleagues who enjoy informal teamwork. The easy difficulty and flexible start time make it simple to fit into a busy day.
It is also a good choice if you have already seen some of Groningen and want a different way to walk through the center. The Sherlock Holmes theme gives the outing a clear purpose, while the digital format keeps the group in charge.
I would hesitate if your phone battery is unreliable, you dislike app-based activities, or you want detailed local commentary. The activity also may not satisfy serious puzzle fans who want difficult riddles or a timed challenge.
Should you book it?
Book this if you want a private, flexible mystery game rather than a conventional guided tour. The $31.07 group price is fair for four people, and the two-hour format fits neatly into a Groningen itinerary.
Before you go, charge your phone fully, install Loquiz from the instructions email, and consider bringing a portable charger. If you value teamwork, simple puzzles, and a Sherlock Holmes plot more than detailed sightseeing information, this is a practical and affordable way to spend part of a day in the city.
