Tickets & booking
I need an invoice for my booking.
We can send you an invoice for your booking. Please email the Fever Support Team at hello@feverup.com.
Please include your ticket ID and billing address.
How do I book tickets for a school class?
School classes can make a group reservation without making an immediate binding purchase. Pupils can become ill, so this avoids the cancellation work for school classes. Larger groups such as school classes are always divided into several teams on the LONDON TRACK and PARIS TRACK, with a maximum of 6 people each. They start in parallel and one after another.
In our menu, open "EVENTS & BIRTHDAYS" and select "SCHOOL WITH A DIFFERENCE". There you will find the reservation link to our Fever ticket shop.
Please note:
If there are children under 11 in the group, the following applies:
Every team containing a child under 11 must include an adult who is booked as an active player and joins in.
In addition, each class needs the group consent form completed by the person responsible for supervision. Bring the printed and completed consent forms on the day of the event.
What should I bear in mind for an event or children's birthday party?
*Players are divided into teams on site.
*Arrival time for EVENT PACKAGES: Please come to reception with your team on time for your booked appointment. You will divide the players into teams here. At this point, please tell our team about any food intolerances or vegan/vegetarian requests for your event meal later.
*Schedule for the LONDON + PARIS EVENT PACKAGES:
A short briefing, access to your event room and time to change.
20 minutes after arrival: Start your track, then return to the event room for your family-style event meal, 1 soft drink per player and water in carafes, followed by time for presents if applicable.
*Schedule for the KIDS and MIX EVENT PACKAGES:
A short briefing, time to change and an immediate start on the tracks.
Afterwards, take your reserved table in JIMIS Bistro for 90 minutes to enjoy a family-style event meal and 1 soft drink per player.
*Would you like to bring a birthday cake? You can. Please bring your own plates and knives. Bringing a cake does not replace the event meal. Event meals are a fixed part of the event booking! Bringing your own drinks or food beyond small snacks and cake is not permitted.
Can I make a reservation?
Reservations are only available for school classes. All other tickets must be fully booked and paid for.
Can I cancel or reschedule tickets?
Bookings are generally binding. In certain cases, such as illness or severe weather disasters, we may be able to reschedule your event. In that case, email the Fever Support Team at hello@feverup.com. Please include your ticket ID.
Can we add individual people on site?
To a limited extent. Additional players can be added as long as there is capacity in the relevant team (2 to 6 players per team).
If adding a player exceeds the maximum team size, another team must be booked.
This is often possible at short notice from Monday to Friday. However, high demand may mean that all places are booked on Saturdays and Sundays. We recommend checking the ticket shop in advance.
Can I reduce the number of people after booking?
Unfortunately not. The ticket is tied to the number of people booked.
However, tickets are not tied to named individuals, so another person can take the place of someone who cannot attend.

Which languages can we choose for the games at KJ Adventure World?
Each team can choose GERMAN or ENGLISH for its mission at reception.
Is KJ Adventure World suitable for people with impairments or disabilities?
Unfortunately not. The 25 adventure rooms focus mainly on physical tasks, particularly jumping, balancing and climbing. The KJAW dining area is accessible and open to everyone.
What is KJ Adventure World and who is it for?
KJ Adventure World is an interactive indoor attraction in Hamburg combining a fun arena, jump house and escape room. Teams complete physical and mental missions in several rooms in a race against time.
It is for children, teenagers and adults aged 6 to 99, depending on the track. It is suitable for families, groups of friends, school classes, companies and events.
How long does a visit take?
Depending on the track, playing time is between 45 and 64 minutes, plus check-in and a briefing. Event packages last about 2.5 hours.
Which tracks are available and how do they differ?
The tracks differ in theme, number of missions, playing time and minimum age. You can choose from:
LONDON TRACK: Ideal for first-time teams | 10 rooms | 64 min playing time | ages 9 and over
PARIS TRACK: For everyone looking for more of a challenge | 10 rooms | 64 min playing time | ages 9 and over
HAMBURG TRACK: A shorter track to try it out | 6 rooms | 45 min playing time | ages 9 and over
KIDS TRACK: The perfect track for children | 7 rooms | 45 min playing time | ages 6 and over
Almost all 25 adventure rooms are different. The exceptions are the Ninja Parkour, included in LONDON, PARIS and KIDS, and the pixel rooms, included in all 4 tracks. We do not reveal further details about the individual tracks. Book according to availability and try the different tracks!
How many people can play in one team?
A team consists of 2 to a maximum of 6 people. If you book for 8 people, for example, the players are divided into two teams. Teams are formed on site at check-in. Teams do not have to contain the same number of players.
Can several teams play at the same time?
Yes. If you have booked the same track several times, teams start at staggered intervals and play the same rooms one after another. This also works well with the optional Team Battle booking.
Alternatively, you can book different tracks for the same time, subject to availability. In that case, you play different rooms but start at the same time and meet each other several times in the playing area.
Is there a minimum or maximum weight?
No, we have no fixed weight limits. Everyone is welcome.
Please listen to your body and decide for yourself whether you feel comfortable with the activities. Some areas contain smaller or narrower passages. If you feel uncomfortable there, you can skip them at any time.
Does height matter?
In some cases, yes. Some passages require a certain height or reach, which is why certain tracks are only open to players aged 9 and over.
For the London, Paris and Hamburg Tracks, we recommend a minimum height of about 140 cm.
If a room feels too tight or uncomfortable, you can skip it and move straight on.
How fit do I need to be?
A basic level of fitness is helpful so that you can enjoy the activities comfortably and without strain. Peak performance is not the aim. You should be able to move freely in everyday life and have no acute health problems. Ultimately, you decide what is right for you.
Is KJAW suitable for pregnant players?
In principle, an uncomplicated pregnancy does not rule out participation. Please always use your own judgement and listen to your body. You can take breaks and skip individual rooms at any time.
Please note:
The London Track has a room in which padded beams move out of the wall. We do not recommend this room during pregnancy because of the risk of impact to the abdominal area.
Please also note that you participate at your own responsibility and we cannot accept liability for this.
Are there rules and restrictions at KJ Adventure World?
Yes!
*You enter the Adventure World rooms without shoes. You can bring your own grip socks or add KJAW socks during the ticket booking process or on site.
*Mobile phones are also prohibited in the adventure rooms to protect you against losing them during the game. You can store valuables in a locker. Adventure World GmbH accepts no liability for valuables.

Team Battle
What is a Team Battle and how do I book it?
A competition between at least two teams with a high-score ranking and a winner's certificate at the end. It can be added free of charge as an extra during the booking process.
To book: Choose a track in the Fever ticket shop, book at least 7 people or several teams, then select the "TEAM BATTLE" extra in the next step of the ticket booking process.
