" Erg leuke escape room! Goede ontvangst, duidelijke uitleg en veel variatie in de opdrachten. Zeker een aanrader! "


" Very cool escaperoom. There were five of us (family aged 11-42) and it was great fun for all of us! It was our first escaperoom, but more will definitely follow! The kids were also very enthusiastic! "

Mare Huizinga

" An escaperoom full of surprises, a good and exciting storyline. The puzzles are fun for everyone. You really have to think differently, which is exactly what makes it accessible. A must play for any escaperoom lover. "


" Fine experience where you spend an hour with 4 to 6 people learning to work together and think differently to find the right solutions. Well designed and with nice surprise elements, and where it is good to ask questions for help. One hour to reach eternal life, this is only possible at Mysterium in Utrecht. You have to experience this once. "
