Discover Leuven while playing! Escape game – The alchemist
A witch hunt turns Leuven into your puzzle board. The Alchemist mixes a self-guided city walk with a story about Josyne, a villager accused of witchcraft, and asks you to solve clues from witnesses before choosing where you stand. I like the freedom to play at almost any hour, and I like that the private format keeps your group together rather than mixing you with strangers. The main drawback is practical: you must bring a charged smartphone, and the small screen may feel cramped during a two-hour game.
The experience begins at De Bruul Park and returns there at the end. You follow the game through Leuven’s streets, using your phone to find and solve the puzzles. It is not a traditional guided tour, so you will not have a person explaining the city in front of you. Instead, the story gives you a reason to pay attention to your surroundings while your group works through the case.

Key Points at a Glance

- Josyne’s accusation drives the story: You investigate a strange witchcraft case and decide whether to defend her or support the charge.
- De Bruul Park is both start and finish: The route begins and ends at Raoul Claesstraat in Leuven.
- Your smartphone is the game tool: Bring your own phone and battery, and consider a tablet if your group prefers a larger screen.
- Play when it suits you: You can access the game for about two hours at any point between midnight and 11:30 p.m.
- The price works best for a group: The listed cost is $23.65 for up to six people, making the per-person cost low when you fill the group.
- The experience stays private: Only your own group takes part, with online support available around the clock.
The Story Begins at De Bruul Park

Your starting point is De Bruul Park, on Raoul Claesstraat in Leuven. This gives you a clear place to gather before opening the game, and the fact that you finish at the same meeting point makes the route easier to manage.
The story places you in the role of an alchemist investigating a bizarre accusation. Josyne, a villager, has been charged with witchcraft, but the reason behind the accusation is not immediately clear. You must question the story through a series of witness puzzles and decide what you believe.
That setup gives the walk a useful sense of purpose. You are not simply moving from one city sight to the next while listening to facts. Each puzzle is part of the case, and each witness adds another piece to the problem. I like that the final decision is not only about finding an answer. Your group must choose to defend Josyne or support the accusation.
The exact witness sequence and puzzle content are not provided in advance, which is useful if you want the mystery to remain intact. You should expect the route and story to guide you through Leuven rather than hand you a fixed sightseeing checklist.

Leuven as Your Playing Field

The game takes place in the streets of Leuven, so the city itself forms the setting. The attraction here is the combination of movement and problem solving. You get a city walk, but the phone keeps you looking for clues, discussing possibilities, and checking your conclusions.
I would not book this expecting a conventional history tour. The included experience is described as a fun city tour, but the main focus is the alchemist story and its puzzles. You may gain a different feel for Leuven by walking with a mission, yet the app is unlikely to replace a local guide who can explain architecture, politics, or daily life in detail.
The street format also means your pace depends on your group. A sharp team may move quickly, while a group that likes to debate every clue can use most of the two-hour period. That flexibility is part of the appeal. You are not being hurried along by a scheduled guide, and you can stop to regroup when the case becomes confusing.
At the same time, a phone-led game asks you to divide your attention. You will be watching the screen while also navigating public streets. Keep your group together and stay aware of traffic, other pedestrians, and where you are walking. The experience is designed for most people, but the information does not promise a fully step-free route or describe the surface of every street.
How the Two-Hour Game Unfolds
The opening stage is simple: meet at De Bruul Park, open the game, and take on the alchemist role. From there, the story sends you toward its witnesses and puzzles. You are likely to spend the first part getting familiar with the app, understanding the case, and agreeing on how your group will share the work.
The middle of the game is where the format should work best. One person may read the information, another may watch for clues, and others can test theories. With a limit of six people, the group is large enough for lively discussion but still small enough to stay organized. If six people all try to control one phone, though, the experience could become crowded. A group of two to four may find it easier to give everyone a role.
As you meet the various witnesses in the story, the accusation becomes the central question. The puzzles are not just isolated riddles. They are meant to help you understand why Josyne was accused and what may have happened. I like this structure because it gives your decisions some story weight, even though the activity remains a game.
The final stage brings you back to De Bruul Park. At the end, you receive a summary of your adventure with photos. That gives the group a record of the outing and adds a pleasant closing touch, especially if you are playing with friends or family.
The advertised duration is approximately two hours. Allow yourself enough time to solve clues without rushing, but remember that the activity is not described as a full-day tour. If you have dinner, a train, or another timed booking afterward, leave a buffer.
The Smartphone Question Matters

You need to bring your own smartphone and battery. Those items are not included, and the game depends on the phone, so arriving with a low charge could spoil the fun before the mystery gets going.
The small screen is the clearest practical weakness. Feedback about the experience specifically pointed out that reading and playing on a smartphone could be harder than using a tablet. The provider said the app can be used on a tablet, although tablet performance is still being improved.
My advice is straightforward: bring a phone with a full charge, carry a power bank if you have one, and consider using a tablet only if your group is comfortable with the app on that device. A larger screen can help several people read the same clue, but you should not assume the tablet version is fully polished.
The activity includes 24/7 online support. That is useful because you are not meeting a guide who can solve a technical issue on the spot. If the app or a puzzle causes trouble, online help gives you a way to ask for assistance while you are out in the city.

Flexible Hours, With One Odd Detail

The game can be accessed for two hours at any time between midnight and 11:30 p.m., from Monday through Sunday. The listed operating period runs from April 3, 2021, through March 22, 2027.
That schedule is unusually flexible. You can fit the game around a day of sightseeing, play after other plans, or choose a quieter time. Families and small groups may appreciate being able to avoid a fixed morning departure.
The midnight start listed in the schedule is worth reading carefully. The practical promise is broad access throughout the day, but you should select a start time that leaves enough room to complete the approximate two-hour experience before your plans or transport require you elsewhere.
The activity is listed under Brussels, yet the actual starting point is in Leuven. Pay attention to that distinction when planning your day. Leuven and Brussels are separate cities, so do not head to central Brussels expecting to find the starting point there.
Is $23.65 Good Value?

The listed price is $23.65 per group of up to six people. That is a strong price if you can fill the group. At six people, the cost works out to about $3.94 per person. At three people, it is roughly $7.88 each, and for two people, about $11.83 each.
That price covers the game, the city walk, 24/7 online support, and the end-of-game summary with photos. It does not cover food, drinks, or the smartphone and battery you use. You are mainly paying for the story, puzzle design, app access, and the chance to explore Leuven in a playful way.
I see the best value for friends, families with older children, or a small group that enjoys solving problems together. For one or two people, the cost is still reasonable, but the group price loses some of its advantage. If your main goal is detailed city history or expert local commentary, spend your money on a guided walking tour instead.
The included photos are a small but useful extra. They are not a substitute for a professional photo session, but they give the group a reminder of the case after the game ends.
Who Will Enjoy The Alchemist Most?

I would recommend this for people who like escape rooms but want to play outdoors. You get the shared puzzle solving of an escape game without being locked inside a room. You also get movement through Leuven, which can make the activity a better fit for a sightseeing day.
It suits groups that enjoy talking through clues rather than racing silently toward an answer. The private format is especially helpful for families or friends who want to set their own pace and make their own decisions about Josyne’s fate.
It may be less suitable if you dislike using your phone during an outing, want a guide to explain every stop, or prefer a highly polished tablet interface. The small screen issue is real enough to plan around. You should also choose your companions carefully: a group that cannot agree on how to read clues may spend more time arguing over the phone than solving the mystery.
Most people can participate, and service animals are allowed. The meeting point is near public transportation, which makes the start easier to reach, though the supplied information does not specify which lines or stops are closest.
Booking Flexibility and Practical Planning

Confirmation is provided when you book. The game is valid for up to three years, which gives you far more flexibility than a normal fixed-date attraction. That long validity can help if your Leuven plans change or you are buying the experience as a gift.
You can cancel for a full refund if you do so at least 24 hours before the scheduled start time. Cancellations or changes made inside that 24-hour window are not accepted for a refund, and the cut-off follows Leuven’s local time.
Bring comfortable walking shoes, a charged smartphone, and any backup battery you normally use for a long city outing. Since no food or drink is included, plan refreshments separately. The activity ends where it begins, so you can arrange the rest of your day around De Bruul Park.
The game is private for your own group. That is worth highlighting because privacy changes the feel of an escape game. You can discuss the accusation freely, choose your own pace, and avoid being paired with people you do not know.
Should You Book This Leuven Mystery?
Book The Alchemist if you want a low-cost, flexible activity that adds a mystery to a walk through Leuven. It is a particularly good pick for a group of four to six people, since the flat price becomes excellent value and the puzzles can support several opinions.
Skip it if you want a traditional guided tour, guaranteed tablet-quality presentation, or a detailed account of Leuven’s sights. The phone is central to the experience, and the route details are part of the mystery rather than something explained in advance.
For most groups, the strongest reasons to choose it are the private format, the unusual Josyne witchcraft case, the free timing, and the chance to make your own final judgment. Just bring a charged device, remember that Leuven is the real location, and allow the full two hours for the investigation.
