Discover Leuven while playing! Escape game – The alchemist
Leuven turns its streets into a puzzle board. The Alchemist is a self-guided urban escape game built around a witchcraft accusation, giving you a playful reason to explore the city while following a story. You take the role of an alchemist investigating why a villager named Josyne has been accused, then solve challenges set by witnesses who may help reveal what really happened.
I like the freedom of the 24-hour access window, since you can begin at almost any time from midnight until 11:30 p.m. I also like the private format and low group price, which makes this a practical choice for a family or small group already spending time in Leuven. The main drawback is that you must provide your own smartphone and battery, and one participant found the small phone screen less comfortable than a tablet.

Key Points Before You Book

- A story about Josyne and witchcraft: You investigate a strange accusation and decide whether to defend her or support the charge.
- Starts at De Bruul Park: The meeting point is on Raoul Claesstraat in Leuven, and the game ends back there.
- About two hours of play: The activity combines puzzle solving with a self-guided city walk.
- Flexible timing: You can access the game any time between midnight and 11:30 p.m. during the operating period.
- Private group format: Only your own group takes part, with up to six people covered by the listed group price.
- Photos and an adventure summary: After finishing, you receive a recap of your game with photos.
The Story Begins at De Bruul Park
Your starting point is De Bruul Park, on Raoul Claesstraat in Leuven. This is more than a place to meet. It is the point where the game shifts from an ordinary city visit into a fictional investigation.
The premise is clear and easy to grasp: you are an alchemist trying to understand a bizarre accusation of witchcraft against a villager called Josyne. You will question or interpret clues connected to different witnesses, solve the puzzles they pose, and decide what conclusion the evidence supports.
That setup gives the walk a purpose. Instead of simply passing through streets and checking off sights, you have a mystery to follow. I like this kind of city activity because it can make a familiar center feel new, especially for children or adults who prefer a task to a standard guided walk.
The details of the individual witness locations and puzzle answers are not provided in advance. That is part of the appeal, since knowing too much would weaken the investigation. You should expect to use the game application on your phone as you move through Leuven and respond to the challenges as they appear.
The route returns to the starting point at De Bruul Park. That makes the activity easier to fit into a day, since you do not need to arrange transport from a distant finish point.

Solving Witness Puzzles Across Leuven

The central part of The Alchemist is a chain of puzzles linked to the story. Each witness provides part of the case, and you work out how those pieces relate to the accusation against Josyne.
This is not a conventional escape room inside one building. It is an urban escape game, so your surroundings form part of the activity. The city walk is included in the play rather than being a separate sightseeing stop. You will need to pay attention to the game instructions and to your position in Leuven as you go.
That format suits groups who enjoy talking through clues together. One person may read the next instruction, another may spot a detail, and someone else may take charge of the answer. Because the game is private, you can work at your own pace without being paired with strangers or worrying about keeping up with a guide.
The private arrangement also helps if your group has different ages or energy levels. You can pause briefly, discuss a puzzle, or move on when ready within the available access period. The game is listed at approximately two hours, but the broad daily availability gives you room to choose a convenient start.
The trade-off is that you are responsible for making the game work. There is no in-person guide leading you from clue to clue. You need a charged phone, a working connection to the game application, and a group willing to read instructions carefully. Online support is available around the clock if you run into trouble.
Choosing Josyne’s Fate

The story builds toward a decision. After following the clues and sorting through the witnesses’ information, you must decide whether to defend Josyne or support the accusation of witchcraft.
That final choice gives the experience a little more weight than a string of unrelated riddles. You are not only trying to finish quickly. You are also trying to understand the case well enough to make a judgment.
I would especially recommend this format to groups who like light role play. You do not need costumes or acting skills, but the alchemist premise gives everyone a simple character to inhabit. It can help younger players stay interested during the walking sections, while adults get a mystery to debate.
The story is also a useful way to see a different side of Leuven. The provided information describes the activity as a fun city tour, but it does not promise a full historical tour or detailed commentary on major monuments. You should book it for the game and the walk, not as a substitute for a traditional guide explaining Leuven’s architecture, history, or food scene.
A Two-Hour City Walk With Flexible Hours

The game is available from 12:00 a.m. to 11:30 p.m., Monday through Sunday, during the stated operating period from April 3, 2021, through March 22, 2027.
That is unusually flexible. You might play during the afternoon between other plans, or start later in the evening when the city visit has slowed down. The broad time window is useful if your schedule depends on train connections, a restaurant booking, or another activity.
Still, an access window is not the same as unlimited time to wander without preparation. The experience itself takes about two hours, so you should leave enough room to complete the puzzles and return to De Bruul Park. Starting close to the end of the daily window would be a poor choice, even though access is technically offered until 11:30 p.m.
The flexible schedule is also helpful for private groups with different routines. Families can choose a daytime slot, while friends may prefer an evening game. Since the activity is self-guided, you are not tied to a fixed departure led by a staff member.
The stated operating dates are important if you are planning well ahead. Check that your chosen date falls within that period before booking, especially if your Leuven visit is scheduled near the end of the availability range.

Is $23.65 Good Value for Six People?

The listed price is $23.65 per group of up to six people, not per person. If six people play together, the cost works out to less than $4 per person, which is strong value for roughly two hours of entertainment and a city walk.
A smaller group pays more per person, but the private format still has an advantage. You are not paying for a conventional guided tour with a fixed route and live commentary. Instead, you are buying access to a story-driven game that your group can play privately at a chosen time.
The value depends on what you want from Leuven. If you want a serious historical explanation, this will not replace a local guide. If you want an inexpensive activity that gives structure to a walk and encourages everyone to take part, the price is appealing.
The package also includes 24/7 online support and a summary of your adventure with photos at the end. Those extras do not turn it into a full sightseeing tour, but they make the activity feel more complete than simply downloading a set of riddles and walking around on your own.
Food and drinks are not included. That is easy to manage in Leuven, but you should plan refreshments separately. Your smartphone and its battery are also not supplied, so arrive with a fully charged device. A power bank would be sensible, although the supplied information does not require one.
Smartphone Screen or Tablet?

The game uses an application, and the phone screen is central to following the instructions. One participant described the game as playful and entertaining for discovering Leuven, but noted that reading everything on a small smartphone screen was less comfortable than using a tablet.
The provider replied that the application can be used on a tablet, although the tablet version is not yet fully optimized and is still being improved. That is useful advice for groups who find phone text tiring. If you plan to use a tablet, make sure the device can run the application and that you are comfortable carrying it around the city.
For most groups, a phone should be enough, but the screen issue is worth considering. Puzzle games often require several people to look at the same clue. A larger screen may help the group work together, while a phone is lighter and easier to handle during a walk.
The practical answer is simple: charge the device before starting, bring the phone or tablet your group prefers, and remember that the equipment is your responsibility.
Who Will Enjoy The Alchemist Most?

I think The Alchemist works best for groups who enjoy solving problems together and want a break from standard sightseeing. It should appeal to families, couples, and friends who like a little story with their walk.
It is also a good option for repeat visitors to Leuven. You may already know the main streets, but the game gives you a fresh reason to move through them. The investigation creates small moments of attention that a normal stroll may not provide.
The activity is private, so it suits groups who prefer not to interact with strangers. Most people can participate, and service animals are allowed. The activity is near public transportation, which makes reaching the starting area easier, though the available information does not specify a particular bus or train line.
You should be comfortable using a smartphone and reading game instructions. If your group dislikes puzzles, phone-based activities, or self-guided tours, the format may feel more like an assignment than a holiday treat.
Booking, Cancellation, and Practical Details

Confirmation is received at the time of booking. Free cancellation is available if you cancel at least 24 hours before the experience start time, with a full refund. Changes or cancellations made less than 24 hours before the start time are not accepted for a refund, and the cut-off follows Leuven’s local time.
The booking is valid for up to three years, which gives you considerable flexibility if your plans change. That long validity is useful when buying the activity as a gift or arranging it before your Leuven dates are fixed.
The experience is supplied by Coddy. It is listed as English-language, so English is the safest choice for groups who want to follow the story and puzzles comfortably.
Although the starting location is in Leuven, the tour summary identifies the broader location as Brussels, Belgium. For planning purposes, rely on the specific meeting point: De Bruul Park, Raoul Claesstraat, 3000 Leuven, Belgium.
Should You Book The Alchemist?
Book it if you want a low-cost, flexible, private way to explore Leuven while solving a mystery. The Josyne storyline gives the walk a clear purpose, and the final decision about the witchcraft accusation adds a satisfying sense of involvement.
I would be more cautious if you are looking for detailed local history, a live guide, or a carefully explained route through Leuven’s major sights. This is a game first and a city tour second.
For a group of up to six, the price is especially attractive. Bring a charged phone, allow about two hours, and consider a tablet if your group finds small text difficult. With those limits in mind, The Alchemist is a smart add-on to a Leuven visit, particularly for families and friends who would rather solve clues than follow another standard sightseeing circuit.
