How to Host a Murder Mystery Dinner Party – The Complete 2026 Guide

A murder mystery dinner party is a fun at-home event where 8 to 20+ guests get to play as characters in a murder mystery story. Everyone will have a role (detective, bartender, musician), a backstory, a secret, and sometimes a motive. Over the course of the night, a murder occurs and guests will have to look at evidence and question each other to try find out who is the killer. Some games have scripted lines for guests to say, while others let you mingle normally and improv your dialogue..

I’ve hosted a ton of these games over my lifetime and been a guest at even more. They’ve been in small flats, large homes, gardens and a few corporate events in restaurants. The majority of them have been a lot of fun, mainly because the host was organized and didn’t leave things until the last minute.

This guide will cover every part of organizing your own game: choosing a publisher/kit, picking the right theme, planning the logistics before you even invite anyone, running the night, and avoiding the mistakes that most people make. By the end, you’ll know exactly what to do and in what order.

You can check out the types of murder mystery dinner party games we create and how they work to have a better overview while reading this article. These games are for 8-20 people

If you have a smaller group of 1 to 4 people, I’d recommend going the route of playing murder mystery case files to solve at home instead. This isa completely different format without any costumes or acting, and is covered in its own guide.

What Is a Murder Mystery Dinner Party?

There are a ton of murder mystery games, ranging different formats and for different audiences. The terms get jumbled a lot, especially when search engines can’t tell the difference between them either.

Murder mystery dinner party games are when a group of friend come over to your house, dressed as characters from the kit you’ve purchased and try to solve a murder mystery. The game kit gives your guests new names, backstories and some secrets that they don’t want anyone else to know. There’ll also be evidence that’s “found” by the host after a murder occurs that gives players clues as to what happened. All the guests will both by trying to find the killer, as well as discover the secrets of every other guest at the party.

It adds a lot of fun to what would be a regular gathering or dinner. At the end of the night, everyone writes down who they think is the killer and why. The host will then read the conclusion from their kit that reveals the killer’s name, and whoever gets it right will become the game’s winner. The host can give them an award certificate that they’ve pre-printed out, or a prize.

You definitely don’t need to be a good actor to play this type of game. It’s really just friends having a bit of fun.

How Many Guests Does It Work For?

The short answer: 8 to 20 players. Depending on the type of kit you purchase, you can increase this amount dramatically, but for the regular party, 8-20 people is the easiest to handle.

Group Size What Works What to Watch For
4-8 guests Intimate, everyone talks to everyone Fewer kits available; very easy to pick the killer
8-15 guests The sweet spot – enough characters/suspects, easy to host Can be managed in most flats/homes/gardens
15-20 guests The story expands with more players; more secrets to uncover Needs more hosting control to keep things on track
20+ guests Works in a hall or large venue; good for networking Hard to manage without a co-host; more intimidating

Guest count is one of the biggest factors for these types of games, and it affects which kits you can purchase. Read our guide on how many guests to invite and why it matters first before you start planning.

If your guest list is uncertain – people that may drop in/drop out, or you’re not sure how many people will confirm – look into murder mystery flexi kits that that have a certain number of primary characters (that must be there in order to play) and everyone else is a secondary character that can cancel without affecting the ending.

How the Night Flows – From Start to End

Guests can’t stay for an unlimited amount of time. They have babysitters waiting, plans for the next day, etc. and need to know that they’ll be home by a certain time. You’ll want to plan your timeline in advance, so that guests aren’t kept too late.

There are lots of different types of these games. Some have a seated dinner, others have snacks, some are scripted, others are improv, some have one murder while other have multiple. In this timeline example, I’m going to roughly use timings from my own games – so it’ll be a party that has snacks, is improv-style and has 3 deaths.

1
Arrivals and pre-drinks (30-40 min) Guests will arrive in costume. You’ll hand out character sheets (guests will have received a copy in advance, but it’s best to provide everyone with a fresh hard copy when they arrive. This is casual mingling time. Guests will slow start settling into their characters.
2
The Murder or Murders (15-20 min) You tap a specific guest on the shoulder and tell them that they need to play out their death scene. This could be a stabbing, shooting or poisoning. That guest will have to do their best acting for this scene. You’ll then announce that you’ve found some evidence on the victim, and show some pre-printed evidence (invoices, diary pages, etc.) This evidence will provide guests with things that they need to question each other about. If there’s more than other murder, they’ll typically take place 30 minutes after the first one.
3
Mingling and Investigating (60 min) This is the total time after deaths combined.Guests will discuss the clues that they’ve found and what they might mean. These could point toward the killer, their motives, or lead to the uncovering of some characters secrets. Some secrets are also motives. The more guests talk, the more they’ll figure out what’s going on.
4
Conclusion (20 min) You’ll hand out cards for guests to write down who they think the killer is. You’ll then read the story conclusion from your kit that will break down all parts of the story piece by piece. Whoever guesses the killer correctly is usually the winner. If there are multiple winners – you can choose from them who is the overall winner.
5
Awards (5-10 min) Most games come with award certificates that you can print out and give to the overall winner, the best dressed person, the best detective, etc. You’ll simply write the winners names on the card before handing them off. You can also give an award prize, like a box of chocolate or bottle of wine if you want to.

Total running time: 2 to 3 hours. I recommend building in an extra 30 minutes of buffer for people that take longer to arrive, and for unexpected things happening (spills, calls, etc.).

Step 1 – Choosing the Right Kit

There are tons of kits out there to choose from. They’re set in different time periods, for different age groups, and for different numbers of players. The most important part of your night is choosing a game that both you and your friends will truly enjoy. A good kit will have interesting characters, red herrings, is well-written and has very clear instructions on how to play.

Things to check before buying:

  • Does it match your guest count, or at least fall within the range?
  • Is there a detailed host guide, leaving nothing to chance?
  • Is the theme one your specific group will enjoy?
  • Are the printable assets high-quality?

For a full breakdown of what to look for, and which factors matter most depending on your group, see our buyer’s guide for choosing a murder mystery kit.

If you’d like to read up our our printable murder mystery dinner party kits, we’ve got detailed information on what they contain and how easy it is to get started.

Step 2 – Picking Your Theme

Theme is a big part of these types of games and will decide the costumes worn and whether guests will want to attend or not. While dressing up in medieval clothes sounds fun to me, most of my friends won’t enjoy or know where to even find the right costumes. So you’ll want to take this into account when choosing your theme.

The most popular themes across the parties I’ve hosted have been:

Theme Category Guest Excitement Costume Effort Required
1920s Speakeasy / Prohibition Very high – everyone knows the Gatsby look Low – flapper dresses, flat caps, feather headbands
Victorian / 19th Century High – interesting costumes, strong atmosphere Medium – corsets, top hats, pocket watches
Hollywood / Film Noir / 1940s High – easy to dress for, glamorous Low – suits, red lips, wide-brim hats
Modern Day / Workplace High – no costume stress, very easy to dress for Low – casual or office wear
Fantasy / Medieval Medium – great for gaming and pop culture fans High – can feel like too much effort for some
Sci-Fi / Futuristic Medium – strong for the right crowd Medium to high

We’ve put together a ranked list of the 15 best murder mystery party themes that guests are mostly likely to enjoy. If you are hosting a 1920s theme specifically, we also have a dedicated 1920s speakeasy murder mystery guide with everything you could possibly think of from cocktail recipes to decorating ideas, along with some free customizable templates that you can download to make your space look era-accurate.

Step 3 – Planning the Details (4 Weeks Out)

Once you have a kit with the right theme, you need to start planning. Four weeks is a pretty comfortable window. Two weeks is workable, if your friends can plan quickly enough. One week is just too tight.

If it’s your first time, the planning might seem like a lot, but our step-by-step planning guide for first-time hosts will walk you through every task in order to get things done the right way – from buying your kit to setting up the table on the night.

If you have specific questions before you start – things like “what if some guests don’t want to dress up?” or “do I need a co-host?” – read these 10 questions every first-time host should answer before starting.

Step 4 – Characters and Invitations

Send character briefs out at least 3 to 4 weeks before the party. These days, most people don’t send invitations by post, but if you do, your dinner party kit, will usually have printable invitation cards for you to fill in. Regardless of whether it’s by post, email or instant messaging, you’ll want to send information from the invitation, a copy of their individual character sheet, as well as costume information.Do not tell them about anyone else’s character. They’ll find out on the night.

The invitation should tell guests:

  • Date, time, and location
  • That it is a murder mystery dinner party
  • Their character information
  • Dress code guidance based on their character or the theme
  • Also mention if you want them to stay in character from arrival or just from when you officially start the game

Tell guests they don’t need to memorise anything. If it’s a scripted game, you’ll have everything ready for them to read, and if it’s an improv-style game, you’ll have a printed version of their character sheet ready with their talking points on arrival.

Host tip: Assign characters based on personality. If I have a game where someone has to dress as a metalhead, I know exactly which person loves rock music enough to play the part. And they’ll enjoy having an excuse to dress up like some of their heroes.

Step 5 – Food and Drinks for the Night

The majority of murder mystery dinner game kits revolve around finger foods. Guests walk around and chat to each other in smaller groups throughout the night, and having snacks that they can carry with them makes it a lot easier. If you’d prefer to have a seated meal, it’s best to search for a game that explicitly lists this in their description, as they’ll include times for eating and base the entire game around it.

In all other games, you can put together some easy finger foods for guests to snack on. Snacks don’t have to be themed, but you absolutely can do that if you want to go the extra mile. Most of my friends are fine with ordering pizza on the night, so that’s also an option. Just avoid anything that might require you to be in the kitchen often or to do a lot of rewarming.

For 20 specific food ideas that I think work great for these evenings – including options for buffet style, seated dining, and dietary restrictions – see our murder mystery party food guide.

For drinks, you can make some themed cocktails/mocktails in bulk the night before, or simply provide some wine and hard drinks that guests can mix themselves. If you’re providing wine, our free murder mystery wine labels can be personalized to match your theme, or be used to make unique gifts for the winners.

Step 6 – Decorations and Atmosphere

Decorations don’t have to cost much at all. In fact, I use mostly free printout to make my place look great. It’s really going to depend on the theme of your how much decorating you’ll need to do, but short of a big Halloween dinner party, you can get away with very little decorations.

For specific decoration ideas with budget in mind, see our list of 10 murder mystery party decoration ideas. For a deeper look at how lighting, sound, and room layout work together, read how to create an immersive murder mystery atmosphere.

Our free murder mystery posters are also worth downloading and printing – they are can be customized to match your theme and event.

Step 7 – Costumes

Costumes are a really fun part of the night. So, it’s important that you make it clear if you expect guests to dress up or not. If you’ve given short notice and the majority of people can’t dress up, it’s better to have everyone dress normal than have half in costume and half without.

If you’re throwing a 1920s murder mystery game, it’s very easy for guests to mix and match items in their closet to put something together that’ll work for the night. The same is obviously true if you’re hosting a game set in modern times.

However, if it’s something that requires guests to go our their way to get hold of, or is expensive – you might have a harder time convincing people to join. If you’re set on a theme that’s a bit strange, I’d recommend looking up some cheap homemade combinations and forwarding those to your friends. In this way, they’re aware that low cost alternatives are absolutely fine, or they can splurge on something more expensive if they want to. You don’t really need elaborate costumes. A hat, headband, or some plastic jewellery is usually enough to look pretty good. Most guests already have something in their wardrobe that could work with a little imagination.

For 25+ specific costume ideas – including no-shopping options – see our murder mystery costume ideas guide for every theme.

Awards and Prizes

Most games will come with an award certificate that you can download and print out in advance. These will have a space for the winners names, that you can fill in on the night. You might want to print out awards for The Best Guesser, The Best Detective and The Best Dressed. These are the most common awards. If your game doesn’t come with this, no worries, you can use our template to personalise our free award certificates for these awards and any other fun awards you can think of.

It’s also not required to give a gift to winners, but it’s a nice touch. I don’t spend a lot of prizes. A box of chocolate, a nice detective novel or a “World’s Greatest Detective” mug are pretty cheap and work really well. For 10 more prize ideas that are low-cost, check out our murder mystery party prizes guide.

Common Mistakes First-Time Hosts Make

After going to enough of these parties, I’ve sees the same mistakes happen repeatedly. They are all avoidable.

Buying the cheapest/most expensive kit available. If you’re having some fun with your extended family without dressing up, free murder mystery party kits are absolutely fine. It’s not super serious and no one is spending money on costumes. But when inviting friends or coworkers over, you’ll have to be willing to spend at least $30 on a good kit with a great story that will keep everyone interested. On the opposite end of the scale, you don’t need to buy a $99 case to have a good time. There’s nothing extra that a publisher could add that can push a game into that price range. $30-$50 is standard for these games.

Not sending character sheets in advance. You’ll hand our printed character sheets at the door, but you absolutely must have sent every guest a copy way in advance. They may very well hate the character or have objections to the things that character does. Always, always, always, tell your friends in advance who they will be playing for the whole night.

Choosing flaky friends for important roles. Games will generally have primary characters and secondary characters in them. Primary characters are required to complete the game. They’ll include the host, the murderer, the victim/s and characters with vital story/evidence. If one or more of these people cancel, you’ll have to take on their role or ask someone to quickly switch roles in order to complete the game. Secondary roles still have fun backstories and unique secrets to discover, but don’t break the game if the guest can’t make it. Choose carefully when matching your friends to characters.

Over-catering the food. If you’re going to cater instead of making finger foods, don’t overspend on food. Guests will be walking around talking, drinking and looking at evidence. You’ll likely end up with way too much leftovers. Either have some plastic containers around to give the extra food away, or order less and keep some store-bought snacks around in case people are exceptionally hungry.

Not keeping track of time. There’s a lot going on during the night and you might need to adjust your timeline a bit. Just be sure that you’re still trying to keep things from ending too late. If guests need to relieve their babysitter, they might be forced to leave before the conclusion. I heard of one game where the killer actually left before the end of the game, which made the ending very anticlimactic.

Too many players in a small space. You want enough room for guests to be able to walk around and join different groups of people that are chatting. You also want to have enough place for guests to sit and relax if they’re too tired to stand after a long day at work. If you have to include your bedroom in the mix for extra space, do it. But don’t force everyone to stand shoulder to shoulder for hours.

Not playing music. Depending on your party, you’ll probably want to add some background music for guests. The first 30 minutes or so can be a little awkward, so background music can help a lot. It can also make the theme feel more realistic, like playing jazz music in a 1920s speakeasy murder mystery.

What About Birthday Parties and Corporate Events?

Murder mysteries work really well at birthday parties – particularly for milestone birthdays where guests expect something more memorable. It gives everyone a chance to dress up and, if you don’t mind knowing who the killer is in advance, you can always set the birthday person up as this character.

For a full breakdown of how to adapt the format for a birthday party, including how to give the birthday person a central role, check out our guide to murder mystery birthday parties.

For corporate settings, the same structure works in a function room or private dining space. The only difference is managing guests who might not know each other as well at the start. Our guide to murder mystery group games for 8 to 20 players covers kit selection for corporate events and large group events of up to 20 guests.

Murder Mystery Dinner Party vs Murder Mystery Case Files

These are two different products that are sometimes confused. You’ll find that search engines will show you both when trying to find a kit to choose.

A murder mystery dinner party has a generally large group of people, in a social setting, trying to solve a murder. It usually involves dressing up in costume and acting.

A murder mystery case file is played alone or with 4 people total. Players look through evidence – photos, newspaper clippings, witness reports, secret codes, maps, lab reports, etc. and try to solve a murder. There’s no dressing up, or acting.

If someone asks whether they should buy a dinner party kit or a case file, the answer is: how many people, and what kind of evening is it? Groups of 8 or more who want to have a social event need a dinner party kit. Couples or solo players who want to feel like detectives and don’t want to do any pre-planning will want a case file.

Frequently Asked Questions

How many people do you need for a murder mystery dinner party?

Most kits are built for 10 to 20 players as most games have around 15 players. Our games are for 8-20 players, so they can work for slightly smaller groups too. Below 8, and it’s too easy to guess the killer. Above 20, it gets harder to manage.

How long does a murder mystery dinner party last?

Our games take 2-3 hours, but always leave some extra time for arrival delays and any problems that may arise. If it’s a seated dinner game, then it will probably go longer.

Do guests need acting experience?

No. Good kits give every character a personality brief and some talking points. No acting experience is required. In fact, it’s a lot more fun when players can’t act.

What is the difference between a murder mystery dinner party and a case file game?

A murder mystery dinner party is a pre-planned event for 8 to 20 people where everyone plays a character, dresses up, and solves a murder. A murder mystery case file is a solo or small-group game (1 to 4 players) where you examine evidence and puzzles, and try to solve a case without acting or dressing up. You can print and play a case immediately without any pre-planning.

Do I need to be good at hosting to run one?

No. The kit does most of the work. Your job is to keep everything organized before the game, and timekeeping during the event. A good kit has a host guide that walks you through every step as if you’ve never done one before.

Can you host a murder mystery dinner party at a restaurant?

Yes, but you need a private room. The game involves guests moving around, speaking in character, and playing out death scenes. A shared open dining room makes that very hard to manage. Book a private hire space and be sure to tell the restaurant what you are doing in advance.
