Haunted-House Murder Mystery Party Game Synopsis:
The cast of the Chamber of Screams Haunted House has spent the Halloween season working hard to terrify the unsuspecting townsfolk of Blackwood Falls. From bloodcurdling screams to perfectly timed jump scares, they’ve earned their stripes in fright.
In appreciation, management has planned a mini Halloween celebration—held right in the employee break room during the nightly intermission. Each night, the haunted house shuts down briefly so the crew can reset scenes and catch their breath. Some say management does it just to build hype and grow the line—but no one’s complaining…except for the guests waiting outside.
Get ready to clock in at the Chamber of Screams. Although a peculiar chill keeps creeping down your spine. Something about your next shift feels… off. This is where your story begins

The murder mystery was great, the only negative I felt was that there was too much information to process on the 2nd round- I think the pre murder and post murder clues should have been on separate cards.
I've attended a few murder mystery parties, which while they were enjoyable, felt alot like people sitting around a dining table reading out bits of a story to each other. This is the first time I've hosted a mystery party and wanted it to be more interactive. Boy did I get my wish! The instructions for hosting we're excellent and gave us much inspiration for food, additional mini games, decor and format. We had a great time with people moving about the party talking to each other and getting really into their characters. The Round clue cards were excellent, giving prompts to give information to certain characters which really helped with the mingling. We were a mixed group of 10 adults and 9 teenagers who did not all know each other. We had some unreliable participants, some did not turn up, others were less enthusiastic. The party pack gave great advice on how to deal with this, and it worked far better than expected. We highly recommend the Chamber of Screams, and we can't wait to do another party from My Mystery Party. The only con I would say is that the instruction video did not do the party pack justice. It was very uninspiring including pictures of people that looked like they were in a really boring lecture. This did turn a few people off.
The game was fun. The story line was easy to follow. There was no direction for the host to leave a murder weapon in the victim kit though.
We ran this murder mystery for a group of Girl Scouts and they had a blast! Watching them go from questioning each other to working together to solve the murder was great.
Great ; game as always
