The Museum has two different puzzles and for some reason we chose to go to the second one, which is more difficult. Because one person bailed on us at the last moment, the host was a bit worried that we won't be able to finish it, because usually teams of 4-10 people solve it. But we did it in 71 minutes \:D/
The concept is the same, you are locked in a room and you have to solve various puzzles to find the key to get out. These range from finding keys hidden in various place, finding numerical combinations for locks, opening puzzle boxes, decypher cryptic messages and so on. It's really fun. This one is bigger than The Dungeon and you have to coordinate better to be able to solve it anytime soon.
One thing that I didn't understand was what is the connection between the story that is posted on the website and all the items that we found in there.
I strongly recommend The Museum and I can't wait to go to another room escape game!
