Review · NANTES
Discover Nantes while playing! Escape game – The alchemist
Nantes becomes your game board. L’Alchimiste sends you through the city with a phone, a mystery, and a string of puzzles tied to a witchcraft accusation. I like the freedom to play privately with up to six people, and I like the way the route brings a simple family activity into the streets of central Nantes. The low group price is another strong point.
The main caution is that this is more of a self-guided puzzle walk than a full city tour. The sightseeing explanations are brief, and one puzzle may depend on access to a site that can sometimes be closed. If you want deep history or carefully guided storytelling, this may feel thin.
Key points at a glance

- A witchcraft mystery in central Nantes: You play an alchemist investigating the accusation against Josyne, a villager whose fate depends on your choices.
- A private game for up to six people: Your group plays together, with no strangers added to your team.
- A phone is your main equipment: You follow the Coddy mobile application from point to point and solve puzzles or complete missions.
- The route includes major Nantes sights: The start is at Place Marc Elder, with the château and cathedral among the places connected to the game.
- Flexible timing: You have about two hours and can begin at almost any time of day, from midnight until 11:30 p.m.
- A very low group price: At $23.22 for up to six people, the cost can be excellent for a family or group of friends, though the experience is light on guided history.
A witchcraft case begins at Place Marc Elder

The game starts at Place Marc Elder, in central Nantes. From there, the Coddy application guides your group through the streets, sending you to points connected with the story.
Your role is an alchemist investigating why Josyne has been accused of witchcraft. The basic question gives the game a clear purpose: find out what happened, work through the testimony of different witnesses, and decide if you will defend Josyne or support the accusation.
That choice gives the walk more shape than a list of disconnected riddles. You are not simply hunting for random clues around Nantes. You are gathering evidence for a case, one puzzle at a time. I like that setup for families and friends because it gives everyone a reason to discuss the answers instead of letting one person simply lead the way.
The story itself is deliberately playful. Do not expect a serious historical investigation into witch trials or a detailed account of Nantes in the past. This is a modern urban game built around a fantasy plot, with the city used as its setting.

How the Coddy app controls the route

You need a smartphone to take part. The application is called Coddy, and downloading it before you arrive is a sensible step. One participant had to contact support after not realizing the app was required, but assistance came quickly and the setup problem was explained.
That small detail matters. A self-guided game can lose its charm if the group is standing at the starting point, trying to work out which app to install. Download Coddy in advance, check that your phone is charged, and make sure your group knows who will hold the device during the walk.
The application leads you to different points of interest. At each stop, you may need to answer a question, solve a puzzle, or complete a mission. The available information does not provide the full sequence of stops, so you should think of the route as an app-directed city walk rather than a fixed sightseeing itinerary with a guide waiting at each location.
I like the control this gives you. You can move at your own speed, pause for a drink, or let younger players take time with a puzzle. The tradeoff is that no guide is present to explain a confusing clue in person or add local color between tasks.
The château and cathedral bring the city into play

The route includes well-known Nantes sights, including the château and the cathedral. These stops give the game a useful sense of place. You are not solving puzzles in an abstract digital world. You are standing in a real city, using the surroundings as part of the activity.
Still, keep your expectations in check. The sightseeing information is limited, with only short explanations attached to some sites. If your main reason for visiting the château or cathedral is to learn their history, you will want to spend extra time exploring them separately.
The cathedral creates a practical issue. One of the puzzles can involve the cathedral, and access may not always be possible. A closure can make that task frustrating, especially if the game expects you to inspect something inside or nearby. Before starting, check the conditions at the site if you can. The game is designed to last about two hours, but a closed location can interrupt the flow.
This is also why I would not treat L’Alchimiste as your only introduction to Nantes. It can point you toward important places, but it does not replace a proper city walk, museum visit, or self-guided history tour.
Solving witness puzzles as an alchemist

The central activity is solving the puzzles connected with the witnesses in Josyne’s story. The questions are designed to be playful rather than academic, which makes the experience accessible to mixed-age groups.
You can expect discussion, guesses, and some trial and error. That social element is the real strength of the format. A family can divide tasks among adults and children, while friends can compete over who spots the clue first. Since only one group takes part, you do not have to keep pace with strangers or worry about giving your answer in front of a larger crowd.
The game also gives you a reason to look around. Even when the historical explanation is short, the puzzle may encourage you to notice a building, square, or detail you might otherwise pass without a second glance.
The downside is that the story may not work for everyone. The plot has been described as silly and lacking interest by one participant, and that is a fair warning for adults seeking a polished mystery. The premise is light, and the quality of the experience depends heavily on how much your group enjoys role-playing and solving simple urban challenges.
I would choose this for people who like games first and sightseeing second. If your group prefers long historical explanations, expert commentary, or carefully researched storytelling, the activity could feel underdeveloped.

Why the private format matters

The booking covers up to six people, and the activity is private. That is important for the mood. You can talk freely, debate the evidence, and make the final choice about Josyne without strangers crowding your group.
A six-person limit is large enough for a family or a group of friends, but small enough for everyone to take part. With the maximum number, you may want one person to read the instructions aloud and another to keep track of the answers. With only two people, the game may feel more focused but also places all the puzzle work on both of you.
The private format also lets you move at your own pace. You are not part of a timed race against another team. The stated duration is about two hours, and you can access the game for a two-hour period at a time that suits you.
This flexibility is particularly useful in Nantes. You can fit the game around lunch, other sightseeing, or an evening plan. The listed opening window runs from midnight to 11:30 p.m. every day, so the available start times are unusually broad. In practical terms, you should choose a start that gives you enough daylight if seeing the streets and exterior sights is part of your plan.
What $23.22 really buys you

The listed price is $23.22 per group of up to six. That makes the arithmetic attractive. A full group pays only a few dollars per person for roughly two hours of entertainment in central Nantes.
I see this as good value for a family or group that wants a low-cost activity. You are paying for a private digital game, a city route, and a shared challenge rather than a guided tour with a local expert. At this price, the lack of a guide is easier to accept.
The value becomes less clear if only one or two people are playing and you expect a full sightseeing experience. The low group price does not change the fact that the historical explanations are short. You may finish the game feeling entertained but still need another activity to understand Nantes properly.
The best way to judge the price is to ask what you want from the afternoon. For a playful break between major sights, it works well. For a detailed introduction to the city, I would spend the money on a conventional guided visit instead, or combine this game with one.
Timing, walking, and practical planning

The experience lasts approximately two hours. Because the route takes place in the streets of Nantes, you should plan for steady walking between the puzzle points. The exact distance is not provided, so I would avoid scheduling it immediately before a fixed appointment.
The starting point is Place Marc Elder, and the activity ends back there. Returning to the same place is convenient if you plan to continue sightseeing nearby or use public transportation afterward.
The game is available every day, with access listed from 12:00 a.m. to 11:30 p.m. This wording covers a very broad daily window. I would not assume that every location along the route will be equally pleasant or accessible at every hour, especially late at night. The app may be available then, but public sites and the atmosphere around them can vary.
Most people can participate, and service animals are allowed. The activity is near public transportation, which helps if you are staying outside the center. Specific information about step-free access, seating, or the route surface is not provided, so contact the provider if those details matter to your group.
You can cancel free of charge up to 24 hours before the start time for a full refund. Changes or cancellations inside that 24-hour window are not accepted for a refund, and the cut-off follows local Nantes time.
The main strengths and weak spots

I see three clear strengths. First, the game gives you a reason to walk through Nantes instead of simply looking at a map. Second, the private format works well for families and friends. Third, the price is hard to ignore when six people share the booking.
The support service is another positive. If you miss the instruction about downloading Coddy, help is available and response time has been described as quick. That matters more than it might seem because the app is essential to the activity.
The weak spots are just as clear. The narrative may feel childish or uninteresting if you want a serious mystery. The history attached to the sites is limited, and the route may include a puzzle affected by cathedral access.
The experience also depends on your phone and the app. A weak battery, poor preparation, or a confusing instruction can make the first part less enjoyable. I would treat the app as part of the equipment, not as a minor detail.
Who should book L’Alchimiste?
I would recommend it to families with children, groups of friends, and visitors who like puzzles more than formal tours. It is especially useful when you want a private activity that fills two hours without committing to a full-day excursion.
It also suits people who already plan to see the château and cathedral. The game can add a playful layer to places you might otherwise visit quickly.
I would be more cautious if you are traveling alone, although the booking structure allows up to six people rather than requiring a group of that size. I would also hesitate if your priority is expert history, obscure corners of Nantes, or detailed explanations at every stop.
Should you book this Nantes escape game?
Book L’Alchimiste if you want a cheap, flexible, private puzzle walk with a clear fantasy story. Download Coddy before you arrive, bring a charged phone, and allow the full two hours.
Do not book it as your main history tour of Nantes. Think of it as a playful way to connect the château, cathedral, and city streets, with enough story to keep a group moving. At $23.22 for up to six people, it offers solid value when your goal is shared entertainment rather than deep sightseeing.
