What happens in Vegas, stays in Vegas!
As the largest and most extravagant casino on the Las Vegas strip, The Paramount Casino is throwing a party of epic proportions. With the highest rollers and the gutsiest gamblers, the stakes are going to be high and there is no limit to what could happen.
Everyone who is anyone in Vegas is sure to be in attendance for this grand event. From the powerful politician to the sexy showgirl, the cunning cocktail waitress to Elvis himself–the guest list of this casino murder mystery is as unlimited as the possibilities of how the night will end.
Like everything else in Vegas, the party will be a gamble and there is no certainty to the events of the evening. Whose secrets will be exposed? Which lies will be uncovered? And who will fall victim to the lawlessness of the night? Your bet is as good as mine.
In this Las Vegas party game, prepare for a sinister night in a city known for its secrets and scandals!

Excellent Question! And one that needs more explaining, please see the “How to Play” Page of our site and/or download a preview file to get a complete understanding of how our mysteries are run!
Absolutely. We make it easy with two types of downloadable invites:
Before you purchase:
Use our RSVP invitations to invite guests and confirm your headcount (we highly recommend this step!)
After you purchase:
You’ll receive email-ready invitations that include each guest’s character description, so you can assign roles and send everything out in just a few clicks.
YES! As host, you get to decide how much or little you know about the murder.
If you want to play along, you will want to read the host’s guide in full to ensure that you are setting the game up correctly WITHOUT letting you know who the murderer is in this murder mystery party game!
In most Night of Mystery parties, the victim doesn’t sit out—they become the investigator for the second half of the game!
Since the victim doesn’t know who killed them, they can jump right back into the action—questioning suspects, gathering clues, and trying to solve their own murder.
