Q: Is escape room MYSTERIUM suitable to play with children?

A: Every child is different, of course. A child who is very scared might not like our room less enjoyable (we are absolutely not a horror room, but the music does become more exciting, for example). Therefore, we do not have a minimum age requirement. However, we do ask that at least one adult always accompanies children under 15. For children's parties, we have an age limit of 11 years, and we also expect at least one adult to accompany them. The maximum group size of 10 people also applies here.


Q: Is an escape room in Utrecht a suitable teambuilding activity?

A: Trust me. This is more exciting than eating sushi or bowling together. I have been organizing corporate events and team building activities in Utrecht for years, and discovering an escape room gave me such a thrill. This really works! An escape room is such a good way to learn to communicate better and more sharply again. During this hour, it's important to work together and listen to each other. And it's still fun and exciting too.

A: MYSTERIUM is the ideal breakout during a meeting. It's a chance to get your mind off things and get to know each other better. I also have the most beautiful meeting room in Utrecht for you: de Grote Werf. Take a look at

A: Mystery can be played in Dutch and English. Please specify your preferred language when booking.


Q: Is escape room MYSTERIUM wheelchair accessible?

A: Unfortunately, escaperoom MYSTERIUM is not wheelchair accessible; they didn't take this into account in my time... There is a chair in the room for people with limited mobility to sit on  


Q: How much time will we spend in the escape room?

A: We work with fixed time slots to welcome as many people as possible in a day. The actual escape experience lasts a maximum of 60 minutes, but with the introduction, debriefing and photo afterwards, people are in for up to 90 minutes. Additionally, the host needs time to prepare the room for the next group. As a result, there is a 1 hour and 45 minute gap between each shift.


Q: Are you recording us in the MYSTERY? Can you send me the tape?

A: What do you think? A MYSTERY always remains a mystery. The cameras are there for your own safety and for the control room to guide you through this real-life puzzle. All riddles and challenges never leave the MYSTERIUM.
