Once again the Chamber has done it! Opus Magnum was definitely one of the best games we played in Prague. Our roommaster was Johan and he was incrediby good at the introduction and helping to the immersive experience. Thank you! (source)

We did Opus Magnum and it was just awesome! The decoration and all the puzzles were just fantastic. To be honest we were not the smartest players, but luckily our roommaster Vasek was very nice (and funny!) and he helped us with some hints throughout the game. we loved it so much that the next day we did another game!

An amazing, thrilling experience, with great “roommaster’s” who clearly care about their craft. The room itself was wonderfully designed and highly immersive. With impressive props, great lighting and music served to amplify the thrilling feel of the game. The puzzles presented in the room are very well thought out and led to many great “Eureka!” moments for me and my girlfriend. Overall, a fun mystery, with world class puzzles and setting. We cannot recommend The Chamber enough. (source)
