Murder Mystery Party Game Synopsis:
The monsters of the International Monster Association are preparing to climb the treacherous paths of Mount Immortality for their annual Monster Summit—also known as the Monster Mash.
This highly classified gathering will take place inside the echoing chambers of the Cave of Misfortune, just beyond the oozing edges of Glop Lagoon. The world’s most fearsome creatures will reflect on the past year’s chaos, chills, and carefully planned terror while preparing their haunts and scares for the year ahead.
Grimoth Jones, the infamous Head of Horrors, is rumored to make an important announcement and recognize the monsters who have demonstrated excellence in monstrous conduct.
You have received your summons. Whether you earned your invitation through cunning, fright, or sheer monstrosity, one thing is certain—the Monster Summit will be an event to die for. This is where your story begins.

Had the minimum (12), and the game flowed well. I was surprised at how many details the boys remembered from the statements. They all seemed to like it.
The 4/10 difficulty seemed appropriate for teens.
Requesting guests to dress up in character worked out great, and added a level of fun.
Although I am very unhappy with my first purchase as we were unable to use it, this game was purchased in its place. My husband and I hosted this party for our employees as a thank you for their positive attitudes and flexibility through all of the Covid 19 mandates that we have endured. We and everyone who attended had and amazing time. There were 18 players, all different ages and all different walks off life. Instructions we easy to understand, flow of game and timeline were excellent . This was the first murder mystery for several that attended and they can't wait to do it again.
So much fun. The twists in this one were wild. We had 18 people from all walks of life and everyone had a blast.
