So, you’ve seen the dramatic photos, you’ve heard your friends rave about the plot twists, and you’re ready to become the proud owner of a living room full of suspicious suspects. Congratulations, Detective — you’re about to host a murder mystery party!
But if you’ve never done it before, you might be wondering: How does this work? Will my guests know what to do? Do I need to build a secret passage under my house?
Fear not — this walkthrough will take you step-by-step through exactly how to play (and host!) your very first murder mystery party, so you can relax and enjoy the thrill without a single dramatic fainting spell on your end.
In case you missed our Beginner’s Guide: a murder mystery party is an interactive group game where guests take on the roles of colorful characters involved in a fictional crime — most commonly, a murder.
The goal? Figure out whodunnit, how, and why, before dessert is served. Or, if you’re the guilty party, your goal is to keep your secret hidden until the big reveal.
Unlike a regular board game, there are no dice, no pieces to move, and no sitting silently waiting for your turn. It’s all about mingling, sharing juicy secrets (real or fabricated), analyzing clues, and accusing each other with flair.
First things first: choose your story!
At Whodunnit Mysteries, we offer an ever-growing collection of plots: posh Regency-era tea parties, suspicious island retreats, spooky haunted manors — you name it.
Here’s what to consider when picking:
Group size: Each game specifies how many characters it includes (some are flexible).
Theme & tone: Do your friends want something light and silly? Or dramatic and spooky?
Age-appropriateness: Some mysteries are better for teens are tweens; some are better suited for adults. All of them are family friendly.
Once you’ve chosen, download your game kit. You’ll get everything you need: character profiles, host instructions, and even prop suggestions (check out our Pinterest Board).
Now comes the fun part: casting your suspicious cast!
Most mystery games come with a list of characters, each with a short backstory and a motive. Some games have essential roles — meaning you need certain characters for the plot to make sense — and some have optional extras to expand your guest list.
Pro Tip:
Send your invitations well in advance, and include each guest’s character sheet. This gives them time to pick an outfit, practice an accent (if they’re feeling dramatic), and get into the spirit.
Modern etiquette bonus: mention the expected vibe in your invite. For example: “Costumes encouraged but not required! Bad fake mustaches welcome.”
A great murder mystery party is all about atmosphere. Good news: you don’t need a Hollywood budget.
Here’s what helps set the mood:
Decor: A few themed props go a long way — candlesticks, faux cobwebs, old books, or an ominous note pinned to the door.
Music: Play ambient background music fitting your setting — eerie strings for a haunted manor or elegant piano for a Victorian drawing room.
Food & Drinks: Keep it simple and easy to eat while mingling. Finger foods, punch, and themed cocktails/mocktails are perfect. Hungry detectives lose focus!
When guests arrive, greet them in character if you like — it’s not mandatory, but it sets the tone right away. Hand out any physical clue cards or additional instructions they need.
Take a moment before diving in to explain:
The game’s goal: figure out who committed the crime.
How they should share or hide information: honesty is not always the best policy!
How and when you’ll pause for clue reveals or plot twists.
When everyone will make their final accusations.
Reassure shy guests: it’s not about acting perfectly — it’s about having fun, being nosy, and laughing at outrageous theories.
This is where the magic happens. There’s no rigid structure, but a typical game goes like this:
1️⃣ Opening Introduction — You, the host, read or announce the opening story: where you are, what happened, and who the victim is (sometimes the victim is a guest character who stays in the game as a ghost or witness in games not written by Whodunnit Mysteries).
2️⃣ Round 1 Mingling — Guests circulate, ask questions, gossip, and share (or hide) secrets.
3️⃣ Clue Drops — At intervals, you (the host) may reveal new clues: a suspicious note, a piece of evidence, or a shocking confession from a side character.
4️⃣ Second Round of Interrogation — Guests re-strategize, accuse each other, and maybe form secret alliances.
5️⃣ Final Accusations — At a designated time, everyone gathers and votes on who they believe the culprit is.
6️⃣ Dramatic Reveal — You read the solution or let the guilty party make a dramatic confession. Cue gasps, laughter, and perhaps a toast to the cleverest detective!
While it’s optional, many hosts love to end with small prizes:
Best Detective (correctly guessed the culprit)
Best Actor (most dramatic performance)
Best Costume (self-explanatory!)
Best Red Herring (the best at misleading everyone)
Prizes can be silly — a magnifying glass, chocolate trophy, or cheap fake mustache pack, or a t-shirt.
“What if my guests are shy?”
Mystery games are amazing ice-breakers. Even quiet folks open up when they have secrets to guard. Plus, the scripts give shy players plenty of guidance.
“What if someone shows up late?”
Assign them a minor character or secret witness — you can weave them in at a convenient plot moment. (Pro tip: Plan for 30 mins of mingling before the game starts to allow late arrivals to settle in.)
“What if people don’t stay in character?”
Honestly? That’s half the fun. Some will improvise wildly. Others will break character to giggle. It’s a party, not Broadway — embrace the chaos!
✅ Read the host guide ahead of time — so you know when to hand out clues.
✅ Have name tags — guests forget who’s who once they’re deep in scandal.
✅ Take photos and video snippets — you’ll want to relive the dramatic accusations later.
✅ Relax! — the best moments come from unscripted laughter and surprise confessions.
In a world where we spend so much time glued to screens, a murder mystery party invites people to be playful, creative, and a little bit devious — all while bonding face-to-face.
It doesn’t matter if you host one in a fancy dining room or your cluttered living room: once the scandal starts flowing, your guests won’t care about the furniture. They’ll be too busy whispering conspiracies, bribing each other for secrets, and squealing with delight when the murderer is unmasked.
Now that you know exactly how a murder mystery party works, you’re ready to grab your suspect list, assign those dramatic roles, and transform your next get-together into an unforgettable night of laughs and gasps.
Whodunnit Mysteries makes it foolproof — clear instructions, juicy plots, and enough twists to keep even your cleverest friends guessing.
So don your detective hat, gather your co-conspirators, and remember: in this game, trust no one. Happy sleuthing!
