Review · NANTES
Outdoor escape game | Vikings – The Relic of Odin
The real hook here is that Nantes becomes your game board. You help Viking leader Ragnar Lodbrok recover Odin’s relic before Moriarty, Sherlock Holmes’s enemy, gets there first. Along the way, you look for details on buildings, decode runes, and learn how Viking raiders reached Nantes in the ninth century.
I like the way the game mixes a walking tour with a puzzle challenge, rather than putting your group in a locked room. I also like the built-in help: a chatbot gives you the mission and clues, while a phone number keeps support within reach if a riddle stops you cold. The main caution is that the quality of your outing depends on careful observation, a working phone, and a willingness to wrestle with a few tricky clues.
Key points to know before you play

- A Viking quest through central Nantes: Start at Place du Bouffay and return there after following clues through the city.
- A story with an unusual villain: Ragnar Lodbrok needs your help, while Moriarty is after Odin’s relic.
- Phone-led gameplay: One internet-connected smartphone per team is required, though one phone per player is recommended.
- Riddles reward close looking: You may need to inspect mosaics, church details, street features, and objects above eye level.
- A social activity for private groups: Your booking is limited to your own party, with group discounts available.
- A low-cost city activity: At $17.74 per person, it offers about two hours of entertainment and sightseeing for less than many guided activities.
Starting the Viking hunt at Place du Bouffay

The game begins at Place du Bouffay, a practical starting point in central Nantes. You do not meet a costumed guide for a traditional walking tour. Instead, you begin a chat with the game’s chatbot and enter the access code supplied with your booking.
The digital companion then gives you the mission details. From there, your group moves through the streets, using the city itself as the setting. This format gives you more freedom than a fixed tour, but it also means you must keep track of the story, the clues, and your position.
The private format is useful for families, couples, and groups of friends who want to set their own pace. You are not sharing the challenge with strangers, and nobody outside your party controls how quickly you solve a puzzle. It also suits team-building outings, since the tasks call for communication, patience, and shared attention.
You should allow roughly two hours. One detailed account describes the game as taking about an hour and a half, so your actual time may depend on how quickly your group spots the clues and handles the harder puzzles. Do not schedule something immediately afterward if you dislike being rushed.

Following Ragnar Lodbrok through ninth-century Nantes
The story gives the walk a clear purpose. Your group is not simply checking off monuments. You are helping Ragnar Lodbrok recover a divine relic connected with Odin, while Moriarty works against you.
That combination is playful rather than academic, but it gives you a reason to notice Nantes in a different way. The activity introduces the Vikings who came to invade the city in the ninth century, their gods, and their runic alphabet. You learn these details while trying to advance the plot, which can make the history easier to remember than a string of dates.
The game also asks you to look at ordinary urban details. A doorway, church feature, mosaic, sign, or decoration may become important. One clue involves identifying a concealed mosaic showing a mythological animal, while another takes place around a basilica and is considered one of the more difficult steps.
That difficulty has a benefit: you are pushed to inspect rather than merely glance. It can also create frustration if the object does not match your expectation of what the clue describes. Read the wording closely, check nearby details, and use the support number printed on your team card before abandoning the mission.
How the phone-based puzzle system works

The game is built around a chatbot. You open the conversation, enter your access code, and receive the mission instructions. As you progress, the digital companion helps direct the next stage of the quest.
You need at least one charged smartphone with internet access per team. One phone per player is recommended, especially if you want several people to follow the clues at once. In practice, you do not all need to stare at screens for the whole game. One person can manage the chat while the rest of the group studies the surroundings and discusses possible answers.
The phone system is convenient, but it changes the feel of the activity. This is not a guide-led walk with stories delivered at each stop. Your group must read, interpret, test ideas, and decide what to do next. The phone gives structure, but the real work happens on the street.
A second or third phone can help a larger group take part. Still, more screens do not automatically mean better teamwork. I would choose one person to manage the chatbot, then have everyone else search and reason together. That keeps the group from splitting into silent phone users.
Bring a portable battery if your phone drains quickly. The game depends on your device, and a low battery would be an avoidable problem.
The clues reward looking up and looking twice

The strongest part of the experience is the demand for close observation. You are not only searching at street level. One piece of advice from the game’s own feedback is simple: remember to look up.
That matters in a city activity because many groups naturally focus on doors, pavement, and the next instruction on the screen. Architectural details above eye level can be easy to miss. Pause at each location and scan the full view before moving on.
The puzzles are varied enough to keep the walk from feeling like a basic treasure hunt. You may need to recognize a symbol, interpret a runic reference, compare visual details, or connect the location with Viking mythology. The challenge is mental as well as physical.
Some clues appear to be more direct, while the basilica puzzle can take longer to decipher. If you get stuck, do not assume the game is broken. The support line remains available during the activity, and the clues are intended to provide a route forward. At the same time, you should know that asking for help can reduce the satisfaction of solving a difficult step on your own.
This is best for people who enjoy puzzles with a little ambiguity. If you prefer a smooth walk with clear facts and no wrong turns, a conventional guided tour may suit you better.

What the walk feels like for families and friends

The activity works well when everyone has a role. One person can read the chatbot’s instructions, another can search for visual evidence, and someone else can work through the Viking names or runes. Children may enjoy the chase and the story, while adults can help keep the group organized.
It is also a good choice for a couple, though two people may have fewer eyes searching than a group of four or five. A larger party can share ideas more easily, but too many opinions can slow down a clue. The private booking means you can choose the group size that fits your style.
The activity has also been used for outings designed to bring young people together. That makes sense because the tasks require listening, cooperation, and shared decisions. It is not a passive sightseeing product. You need to communicate if you want to finish.
The physical demand is moderate. You walk through the city for around two hours, so comfortable shoes matter. Bring water and, if you tend to tire between meals, a small snack. There is no indication that the activity requires strenuous exercise, but anyone with limited mobility should consider the length of the walk and the ordinary surfaces of a city route.
Service animals are allowed. The activity is near public transportation, which makes the starting point easier to reach without a car.
What to pack for a smoother two-hour game

Keep your preparation simple:
- A fully charged smartphone with mobile internet
- A notebook and pencil for each team
- Comfortable walking shoes
- Water
- A snack if needed
- An external battery for your phone
The notebook and pencil are not decorative extras. Writing down letters, symbols, numbers, or partial solutions can help your group see patterns that are easy to lose in a chat window.
One phone per team is mandatory. One phone per person is recommended, but you can decide how much screen access helps your group. If you have connection trouble or cannot add another player, contact the operator during the game rather than spending too long trying to fix it alone.
Is $17.74 good value for Nantes?

At $17.74 per person, this is a reasonably priced way to spend part of a day in Nantes. You receive a self-guided city walk, a themed story, puzzles, digital instructions, and roughly 90 minutes to two hours of activity.
The value is strongest if you already enjoy escape games or puzzle hunts. You are paying for the structure and story, not for a live guide’s commentary. If you compare it with a standard walking tour, you will get less continuous explanation of Nantes and more active problem-solving.
Group discounts can make the price more appealing for a larger party. Since the activity is private, your group also avoids the social uncertainty of being placed with people you do not know.
There are a few practical limits. The experience depends on your phone, and the route may take longer if your group struggles with a clue. You should also be comfortable spending much of the outing looking for evidence rather than simply listening to a guide.
For a budget-conscious visitor, the combination of entertainment and city orientation is sound. You get to see central Nantes while doing something that asks you to pay attention.
The tricky points you should expect
The game’s clues are designed to lead you forward, but not every step will feel obvious. The basilica puzzle has a reputation within the game for being especially hard to decipher. Before asking for help, reread the clue, inspect the area again, and check whether you missed a detail nearby.
A clue describing a mosaic may also require careful interpretation. The relevant object may not look exactly like the word suggests at first glance. This is where the experience can divide people. Some players enjoy the need to question their first impression. Others may find the wording too loose.
The operator can be reached by phone throughout the adventure. That safety net matters, especially if you are playing with children or have a limited time window. Use it when needed, but try to preserve some of the challenge for your group.
The game is not designed to reward rushing. You need to observe, talk, and confirm. If you race from place to place while focusing only on the screen, you may miss the details that make the walk worthwhile.
Booking, cancellation, and practical limits
You receive confirmation when you book. The activity is offered daily, with the listed operating hours covering the full day and night. Since the game starts when you launch the chatbot, you should still choose a sensible daylight time so that street details are easier to see.
The meeting point is Place du Bouffay, 44000 Nantes, France. The game ends back at the same meeting point, which makes it easier to plan your next stop.
Free cancellation is available if you cancel at least 24 hours before the local start time. Cancellations or changes made less than 24 hours ahead are not accepted for a refund.
The activity is private, and group discounts are available. It requires a moderate level of physical fitness, mainly because you will be walking and standing while searching for clues.
Should you book Vikings: The Relic of Odin?
Book it if you want to see central Nantes through a game, enjoy solving riddles, and like activities that make you inspect the city closely. It is especially suited to friends, families, couples, and organized youth groups who enjoy working together.
Think twice if you want a detailed, guide-led account of Nantes or if phone-based activities annoy you. The hardest clues may test your patience, and the outing works best when everyone is willing to look carefully and discuss possible answers.
For $17.74, this is a good-value choice for an active two-hour break in Nantes. Bring a charged phone, paper, pencil, and comfortable shoes. Most important, slow down enough to notice what the city is showing you.
