Overview of artificial intelligence

AIThe majority celebrate the atmosphere, storytelling, and level of detail, especially with the actor. The puzzles are mostly easy and rather few; the focus is clearly on immersion and jump scares. The team is seen as warm and attentive; once, a door was accidentally not properly secured. Some find the room a bit old or dusty, which others feel suits the mood.
WeaknessesPuzzles are on the easier side and not very numerous; puzzle fans might miss more brainteasers. Isolated quality issues like an accidentally open door and, for some, a slightly dusty, dated look.
StrengthsFantastic sets, strong sound and lighting effects, and tight, gripping staging. The live actor clearly raises the tension and delivers real goosebumps. Friendly, committed staff and a fitting showdown.
SecurityThe team comes across as attentive and steps in via radio when needed. A one-off case of a door not correctly locked was reported; overall, guests felt well taken care of.
Level of fearVery scary and nothing for the faint-hearted; sensitive players or children should avoid it. Without the actor it's milder; with the actor it gets really intense.
Actors' gameThe actor is optional but extremely effective, playing precisely on the group's nerves. Some skip it or abort the add-on because the intensity is very high.
Quality of riddlesFair and mostly well guided, but rather easy and limited in number. The focus is clearly on atmosphere and story instead of complex logic. If you want puzzles, you get solid fare; if you want horror, you're in for a treat.
PlotYou follow the trail of the missing girl Sandy through basements, corridors, and secret passages and stumble upon a diabolical secret. It tells the Nun's backstory; your goal: rescue, survive, escape.
Difficulty levelPuzzle-wise, easy to medium; the thrill is the real opponent. Beginners will do fine; experienced puzzle pros might wish for more depth.

We treated ourselves to The Unknown and it was insane. The two of us were so scared that we asked them to call off the actor in the first room; otherwise it would have been too much. Everything is perfectly done and unbelievably scary, the team is super lovely — it took us hours to calm down.

We played Unknown and The Nun and can warmly recommend both. You’re immersed in the story from the very first second; the effects and sets are lovingly executed, sound and lighting are perfectly coordinated, and both feature a strong showdown. Great team, multilingual, and for me among the top rooms Europe-wide.

I’ve been to many escape rooms, but this one blew me away. The team is friendly, the puzzles aren’t too difficult, and it’s the story and atmosphere that really make it. Props are top-notch, and the acting is the crowning touch — a must for horror fans.

Strong atmosphere, but the puzzles were too obvious for me. Still: top-notch staging and very polished overall—especially if you’re after horror rather than mind-bending puzzles.

We left out the live actor and it was still really creepy. The story grabs you right away, and the lighting and sound are on point. Highly recommended for anyone who likes to get scared.

A solid, quite creepy room with an exciting layout and cool effects. The puzzles are rather easy and mostly obvious; it becomes challenging because, with all the tension, you make slower progress.
