    Mystery Synopsis

    The most highly anticipated VIP party in Las Vegas is almost here! The Cosmo Casino & Resort is set to host a world class soiree for celebrities, news media, and a few Vegas locals that were lucky enough to score tickets. Some of the most prominent figures of our time will be in attendance and this will certainly be a night to remember. However, there is a situation. The city of Las Vegas has been terrorized by a serial killer with an MO of attending VIP events held on the strip. The killer, known as the Sin City Slayer, chooses victims from unsuspecting party guests. The Las Vegas police are currently working with federal agencies to catch this deranged predator. Hopefully, the killer doesn’t have a ticket to this event. This is where your story begins.

    How to Host a Large Party

    • 18 unique players from the main game.
    • 12 unique players from expansion pack #1 (purchased separately)
    • 8 unique players from expansion pack #2 (purchased separately)
    • Up to 15 paparazzi expandable duplicate players to play with Reagan Paratzy (expansion pack #1, purchased separately)
    • Up to 15 Monster Muggies Cast member expandable duplicate players to play with Logan Mack (expansion pack #2, purchased separately).

    The expandable players are not unique story lines, but rather are supporting players for Reagan Paratzy & Logan Mack. They will, however, have duplicate clue cards each round, they mingle each round like everybody else, and they still guess whodunit. The only difference is that they will not have a unique story line. These players are great for shy/reserved players, last minute RSVPs &/or adult guests who may consume a few too many cocktails.

    If you wish to host this (or any other) game for profit, you will need a commercial license or provide us with your 501C number for a charity fundraiser - click here.   Note: we are not issuing waivers between September 2020 and January 2021.

    1. Great party!

      After I mentioned having done a MMP at a restaurant, my daughter was determined to do one at home for her 11th bday with family. She looked at all the options, picked this one, and I bought the download package. There was a lot to go through and it seemed a little overwhelming at first, but after my second read through, it became clear that you actually don’t have to do much except hand out the clue cards and your guests will take care of the rest. We had a younger child and and adult I knew would not be participating no matter what was going on around them, so we assigned them non-required parts—i printed out the character sheet for my daughter to pick roles and just made sure her assignments would work with the story and people so she didn’t know whodunnit. If you are in character, your guests will be immediately in character. I answered the door as the wealthy socialite, and my guests immediately responded as their characters, and it turned out great. It was hysterical. My son was the magician and he learned a card trick to do with people as he walked around. My husband was the poker player/comedian and would randomly pull out his phone and loudly give a really corny joke. It all flowed really well. We played a nerf gun poker game between rounds to space things out. Took about 3 hours to complete with the game and food in between. Multiple people said it was a great change and asked if we could do another one at xmas! A month later now and family members are still treating each other like the game. Will definitely be doing another one. on Nov 25th 2021

    2. Great evening and convincing plot

      This murder mystery was actually written so that guests could identify the murderer. The characters were all funny and unique. on Nov 7th 2021

    3. So much fun!

      Our group of 12 women had so much fun playing this! It was even better that everyone dressed up as suggested and played along the whole time. We will definitely be playing again soon! on Aug 29th 2021

    4. Totally awesome evening!

      This is the second murder mystery I’ve done and every person in attendance has completely enjoyed ourselves and we plan on doing it again. Ending/revealed can be a little confusing and could use a little more clarification but we have no complaints and absolutely loved it! on Jan 4th 2021
