Choose the best type of murder mystery for your Halloween party:

  • Scripted or turn-based murder mystery games where all players receive scripts from reading and are prompted with staged questions.
  • Interactive Murder Mystery games provide players with details of their characters before or at the game's start and solve the mystery through interacting with other characters.
  • Dinner Theatre Murder Mystery games are professionally catered troupe of actors with live staging and interaction with the audience at a venue.
  • Flexi Murder Mystery games are games where the murderer is chosen randomly at the start of the game, usually by drawing a guilty card in secret.
  • Digital/virtual murder mystery games are played on virtual hosting platforms such as Zoom or Discord, which are interactive, scripted, or Flexi.

Murder mysteries are fun for your guests, whether you choose to do a murder mystery dinner party or play together online from the comfort of your home.

2. Choose a murder mystery theme

You can host any number of themed murder mystery parties, and you don't have to limit yourself to monster or ghost themes. You can choose a 1920's jazz club, a pirate ship, or a masquerade ball. It's up to you and your guests!

If you instead do not choose a specific genre, keep it simple as a Haunted house Halloween party murder mystery! Your guests dress in traditional Halloween costumes, which is so much fun. And don't forget, a virtual Halloween party also benefits from a mystery party theme. Never underestimate the power of fancy dress!

Some popular Halloween murder mystery dinner party themes right now are:

3. Send Invitations

Make a guest list. Getting guests to RSVP to your murder mystery party as early as possible is a must. Know your participants to plan character assignments for the murder mystery game early. Typically, a murder mystery game requires six or more people, so confirming the guest list is essential to the game. We recommend sending invitations a minimum of two weeks in advance to allow sufficient planning. Ensure to include everything your guests need to know, including theme, costume requirement, and expectations.

Create invitations that match the party theme. You can use paper or e-invite. Some murder mystery game kits contain invitation templates. Nonetheless, ensure your guests have an easy way to RSVP. You'll closely track RSVPs to ensure you have enough people for the game to work.

4. Assign character roles

Your guest list will also set the tone of your party. Extroverts will play up your dramatic character, while introverts will enjoy roles that don't take center stage and give them the freedom to sleuth. Ensure you know which roles will suit which friends or family members.

If you have more guests than characters or some who sustain from gameplay, you can assign bystanders or audience members non-participant roles that allow them to dress up and mingle but not play the game. You may want to give these individuals roles to help with prize award giving. However, our experience is that even the shyest people will enjoy a murder mystery game.

You can assign characters;

  • in advance and send out character information with the invitation, or
  • wait for your RSVPs and then assign roles.

We recommend finalizing your guest list before assigning roles. When you assign a role, include costume suggestions to make or break the illusion of the theme. Ensure characters know their roles and costume suggestions in advance, which is why you need at least two weeks to plan.

5. Decide on an event space

Choose a venue suitable for your guest list. Unless you're hosting a large-scale game or murder mystery dinner theater show, your home will usually be the best venue. You may want to use multiple rooms for the game to facilitate private discussion amongst guests in character. If you have a small group placing multiple smaller tables around the room also gives your guests opportunities to have private conversations while in character. If you want to avoid large clean up, you can use party venues. Take inspiration from your theme, and rent out a space to convert into an asylum, cocktail bar, vampire den, or mansion to set the scene.

6. Plan your Halloween party menu

Are you planning on serving dinner? How about snacks or drinks? These games take several hours, so providing sustenance is a must. Some people choose to do a murder mystery dinner party as a formal sit down, especially popular in murder mystery theatre and performances. However, planning a murder mystery game and cooking a three-course meal is difficult to pull off. If you have the budget, consider catering for the party, which allows you to focus on the party.

We recommend finger foods and hors d'oeuvres that encourage your guests to mingle. Multiple designated snack areas encourage your guests to conjugate in different areas around your party space and give you more options for decorations. Ensure your menu reflects the Halloween theme for the evening.

If you're planning a virtual murder mystery party, get creative with a menu! Snack breaks are a must, so encourage your participants to make Halloween treats and snacks in advance to bring to the video call.

7. Decide on drinks

Halloween party cocktails

You may wish to include a signature cocktail or mocktail for your murder mystery party. Mocktails and cocktails add decorations and flare to your event, offering interludes between game rounds. If your budget permits or you prefer a more comprehensive selection of beverages or elaborate Halloween mixtures, hire a professional bartender or mixologist. You may also opt for a simple BYOB approach or stock your fridge with pre-mixed or bottled beverages. This ensures cleanliness and cuts back on cleaning at the night's end.

If you're planning a virtual murder mystery party, get creative with drinks! There is no reason why your participants can't win up a fancy Halloween treat of their own at home. Consider sending your guests a signature cocktail or drink list with instructions and ingredient lists.

8. Decorate party space

Decorations allow you to set the mood of your Halloween murder mystery party theme. Transform your room into a haunted mansion, asylum, or vampire den. Be as elaborate or as simple as you'd like— remember, a bit of imagination goes a long way when the game is afoot.

Some easy decoration ideas include:

  • Fake cobwebs
  • Floating candles, lanterns, and fairy lights
  • Skeletons, tombstones, bats, brooms, and black cats
  • Classic pumpkin art
  • Bottled potions, cauldrons
  • Anything black!

Consider using center pieces and Halloween place settings if you plan to have tables for your dinner party. Multiple smaller tables also allow your guests to have private conversations while in character.

As a Zoom murder mystery party host, you can add spooky ambiance and thematics with Halloween Zoom backgrounds.

9. Create Halloween music playlist

Set the ambiance with your spooky Halloween playlist. YouTube, Amazon Music, Spotify, or other streaming services are an easy way to play music at your Halloween party. Consider creating a playlist ahead of time. Ensure your music fits your party theme: 20s jazz, 80s Pop, or spooky Halloween-themed music; ensure your playlist lasts the entire night - or at least until the murderer is revealed! Murder Mystery kits may include video clues and sound effects, so ensure that these do not interfere with the party music.


10. Play the game

Plan your night

Party prep also includes planning the structure for the evening to move the game forward. If planning a dinner party, ensure you schedule mealtimes between rounds. You may wish to serve food at the beginning of the evening, then start the game. Or, you can include snack and drink breaks between the rounds. For murder mystery kits usually provide guidelines and recommendations for beginning rounds, new clues, and game elements.

At the end of the game, leave some time to allow people to debrief and explain their theories or game perspective. So much can happen between guests and secret story plots, so the "wrap-up" should be included in your game structure.

Make name tags

Part of the fun of murder mystery parties is acting in character, but it's not always easy to remember all your guests' names—especially if you have many guests. Name tags allow your guests to stay in character throughout the night. Prepare the name tags in advance.

Layout the rules

Before the game starts, you'll want to inform your guests of all the game rules and other information. Sending out a secondary invite or reminder as a guide to your night is recommended, and it would include:

  • Character information booklet
  • Costume suggestions
  • Clue cards
  • Gameplay, schedule, and rules
  • How your players can win
  • A guide to how long the game will last

To ensure you can run the game properly, reiterate these rules at the start of the night and give a rough guide as to when you expect the game to end.
