To run an office murder mystery game night you need five things: a story everyone can follow, a role for every person who turns up, clues that keep the whole room working at once, food that survives being ignored for an hour, and somebody willing to be game master instead of playing. Budget two to three hours. Whether you are calling it an office murder mystery party or a game night, the planning is the same, though the two names set different expectations: a party suggests costumes and characters, a game night suggests puzzles, and that is really a question about which box you buy. The step most organizers get wrong is the third one, and this guide spends most of its time there, because a night where two confident people solve everything while the rest watch is the standard failure and it is entirely preventable.
We design at-home escape room games for a living, so the puzzle half of this is our day job. The catering advice you can take or leave.
Choosing a theme and planning your office murder mystery game night
The theme decides your cast, your clues and how much your colleagues have to pretend, and that last one is the part to think hardest about. If you have already advertised the evening as an office murder mystery party, people will arrive expecting to dress up and play somebody, so work out whether that is what you are actually running before the invitation goes out. A 1920s speakeasy or a country house weekend gives people costumes and accents to hide behind. A theme set in a fictional company gives them almost nothing to hide behind, which is funnier for four people and excruciating for everyone else.
Our rule of thumb for a work crowd: pick a setting far enough from the office that nobody's real job is in the room. We have written up ten murder mystery themes that work at home and three that reliably do not, and the ones that fail are almost always the ones that ask shy people to improvise as themselves.
On logistics, decide these before you invite anyone. How long you have, including the half hour at the start where people arrive and get drinks and nothing happens. Whether the room can be rearranged into small groups, because a single long boardroom table is the worst possible shape for this. Whether attendance is genuinely optional, and whether you have said so in a way people believe.
A note on scale. Most boxed games in this category are built for somewhere between four and six players. If your team is twenty-four, you are not running one game night, you are running four tables of six in parallel, and that changes your shopping list and your room. It also makes the evening better, because tables finish at different times and start comparing notes.
Selecting characters and assigning roles
Count the people who have actually said yes, then add two, because somebody always brings a partner or a colleague who heard about it. Scripted murder mystery kits usually specify a player count and get awkward outside it, so buy for the number you expect rather than the number you invited.
Assign the talkative roles to people who want them. This sounds obvious and it is routinely ignored in favor of casting against type for comedy, which works on television and fails at work. The person who has to deliver a tearful confession in front of their manager did not consent to that when they replied to a calendar invite.
Give everyone their character notes at least a day ahead, and keep them short. One page. Half of your team will read it in the elevator on the way up, and a one-page brief survives that. Four pages of backstory does not.
Two roles worth creating that most kits do not include: somebody whose job is to write things on a whiteboard as the room discovers them, and somebody who is explicitly allowed to sit out the acting and work only on the physical clues. That second role is what stops your quietest colleague from having a bad evening.
Creating clues and puzzles that keep the whole room busy
This is the section we can help with more than anyone else writing about office parties, because it is what we do all day. We publish the rules we design escape room puzzles by, and four of them decide whether an office murder mystery night works.
The first and most important is that a puzzle has to survive a group. If a puzzle has a single thread running through it, one person picks that thread up and solves the whole thing, and everybody else watches them do it. In our own testing that is grounds for rejecting a puzzle outright, no matter how elegant it is. At an office event it is worse than it is at home, because the two people most likely to grab the thread are the two most senior people in the room, and now your quiet half is standing near the snacks watching their boss solve a riddle.
The fix is parallelism. Build clues that come in several strands which have to be worked at the same time and then combined: three people each holding part of a phone number, or a cipher whose key sits in a different envelope from the message. Anything where the final answer physically cannot be produced by one person is doing the work.
One of our boxes laid out. The number of separate physical pieces is what lets six people work at once instead of watching one person think.
The second rule is that everything needed has to be in front of them. Every element required for the solve is present in the room, and nothing required is assumed. Homemade office mysteries fail here constantly, because the organizer knows something the players do not: that the finance team sits on the third floor, or that Dave once had a beard. If the clue needs it, put it on the table.
Third, difficulty should live in the insight rather than the hiding. You can make the leap less obvious, or you can make the paper harder to find, and only the first is design. Taping an envelope under a chair buys ten minutes of furniture inspection, no thinking, and a real chance the cleaners get there first.
Fourth, every puzzle should announce what kind of answer it wants before it asks for one. If the answer is a four-digit number, the solver should know it is looking for four digits. A stuck room should be stuck on something specific rather than stuck on what the question even is.
Two more practical things we would not skip. Set a twenty-minute ceiling: if one clue holds the room up for longer than twenty minutes, that is a fault in the clue, not in your colleagues, and your game master should hand out the answer and move on. And spread the difficulty deliberately, so that only some clues sit at the hard end and the rest are a step easier. A night where every single puzzle is a twenty-minute wall is exhausting rather than satisfying, and at 9pm on a Thursday people will simply leave.
One more, and it is the one nobody does: get somebody else to test it. You cannot test your own puzzle, because you know the answer and knowing the answer makes the path look obvious. Find one colleague who is not coming to the event and walk them through it cold. You will find at least one clue that only works inside your head.
Your game master should also prepare hints in three levels for each clue, rather than improvising them. The first nudges toward what kind of puzzle it is, the second toward the mechanism, the third gives the answer outright. Improvised hints are almost always too generous, and a room that gets handed answers stops trying.
If that list reads as more work than you were expecting to take on, there is a section further down on buying a box instead.
Decorations and props for an office murder mystery party
Decoration matters less to a murder mystery game night than lighting and seating do, which is not what most guides tell you. Two lamps instead of the overhead fluorescents will do more for the atmosphere than any amount of themed bunting, and moving the chairs into clusters of five or six is worth more than either.
For props, the rule we use on our own components is that physical design carries instruction. A card with a folded corner invites folding. A wheel with a rivet through the middle invites turning, with no explanation needed. If you want people to hold a document up to the light, put it in a stack of things that are obviously meant to be handled, not pinned to a wall.
If your theme is a 1920s speakeasy, a few period objects on the table beat wall decoration every time, because people pick objects up. Ask before you stick anything to the walls or the windows, and check whether your building has rules about candles, because a lot of them do.
Food and drinks that survive a game night
Food at a game night gets eaten in the first forty minutes and is then ignored completely, so plan for that rather than for a dinner. Things that can sit at room temperature and be picked at with one hand while the other hand holds a clue. Anything requiring a knife and fork competes with the game and loses.
Keep the food on a separate surface across the room from the clues. Grease on a document is funny once, and then the document is gone and your game master is reading the answer out.
On drinks, one thought from having watched a lot of people solve puzzles: alcohol and ciphers do not mix, and the drop-off is steeper than people expect. If the puzzles matter to you, put the bar after the reveal. If the social part matters more, accept that the game will be a backdrop and buy something easier.
Put out non-alcoholic options somebody would actually choose, and find out about dietary requirements before the day rather than at the door. This is a work event, so the ordinary rules about not making people announce their restrictions in front of colleagues apply.
Should you write your own or buy a boxed game?
Writing your own is a bigger job than it looks from the outside. Between drafting a story, making the clue materials and getting somebody to test them, reckon on a couple of full days rather than an evening, and expect the finished thing to run shorter than you planned. If you have that time and you enjoy the work, nothing off the shelf will fit your team as well.
If you do not have that time, buy something. For a classic whodunit where everyone plays a character with a script and a secret, you want a dedicated murder mystery party kit. We do not make those, so we are not the right answer for that format and would rather say so than sell you the wrong thing. Publishers who do make them, such as Night of Mystery, whose own 15-step hosting guide is worth reading, will serve you better. If you go that way, the hint structure and the twenty-minute ceiling above still apply.
What we make is different, and for a lot of offices it is the better fit: at-home escape room games where a table of up to six works through physical materials together, checking answers in an online companion guide as they go. Nobody has to act or improvise in front of their manager, and everyone has something in their hands. If the group-survival problem described above is the thing you are worried about, this format sidesteps it by design.
Three of ours suit a work crowd:
- Blackbrim: 1876, our Victorian detective game, is the closest we come to what people mean by a murder mystery, though it is honestly a manhunt rather than a whodunit: you work as a private detective chasing a criminal called Reager Skinner. 1 to 6 players, 2 to 4+ hours across two parts, ages 14+, 4.8 stars from 525 reviews.
- The Fifth Column, set in Manhattan in June 1945, has your table stopping a Nazi plot after Germany has already surrendered. It is a wartime thriller, so there is nobody to accuse and no part for anyone to play, which is what makes it easy on a work crowd. It outsells everything else we make, and it is the least expensive of these three to buy four of. 1 to 6 players, 2 to 4+ hours across two parts, ages 14+, 4.9 stars from 151 reviews.
- La Famiglia, set in 1929 Chicago, puts your table on the FBI side of bringing down a mafia organization. It tends to land well with groups who want crime without a corpse in the room. 1 to 6 players, 2 to 4+ hours across two parts, ages 14+, 4.8 stars from 99 reviews.
The practical detail for an office: nothing in our boxes needs cutting or writing on, so a game comes out of the evening intact and the next team can play it. For a company running the same event across several offices, that is the difference between a per-head cost and a one-off one.
For groups of twenty and up we handle it directly instead of making you place a large web order. Our corporate gifting page covers orders of twenty games or more, and the fastest route is to email gifting@puzzlingpursuits.com with your headcount and your date so we can sort quantities and shipping with you. Do this arithmetic before you ask for a budget: four tables of six needs four boxes, not twenty-four.
The clues played to different family members' strengths, giving everyone the feeling of participating.

Our final tips for a successful office murder mystery game night
These are the things that only show up once you have actually run an office murder mystery game night.
- Send the details and the expectations well ahead, including how long it will run and whether costumes are genuinely optional. People plan their evening around your answer.
- Say the rules out loud at the start even though you emailed them, and say how to ask for a hint. Rooms that do not know hints exist will sit stuck rather than admit it.
- Appoint a game master who is not playing. Somebody has to hold the answers, watch the clock and notice which table has gone quiet, and that person cannot also be solving.
- Give the quiet people a job with an object attached. Sorting documents, running the whiteboard, operating a cipher wheel. Participation follows having something in your hands.
- Decide in advance what happens if a table finishes early, because one will. A short bonus puzzle beats twenty minutes of them talking loudly beside a table that is still working. Our free Puzzle Archive covers this: fifteen puzzles graded from introductory to expert, solved in the browser with optional hints, so there is nothing for you to prepare. Ten of them are also free to print if you would rather have paper on the table.
- Take photos, and ask first. It is still work.
If part of your team never makes it into the office, the planning is different enough to need its own guide. We wrote one on escape room team building for remote teams, including what a boxed game really involves once you are shipping to a dozen separate addresses.
Common questions
These are the ones we get asked most by people organizing a work event rather than a party at home.
How long does an office murder mystery game night take?
Plan for two to three hours from the moment people sit down, and add half an hour at the start for arrivals and drinks. Scripted murder mystery party kits usually run 90 minutes to two hours. Our boxed games run two to four hours or more across two parts, which is longer than most weeknight work events want, so a lot of offices play part one only and send the box home with somebody.
How many people do you need for an office murder mystery?
Most boxed games and party kits are built for four to eight players and get awkward outside that range. For a bigger team, run parallel tables of five or six rather than one large group, because a group of fifteen around one set of clues means most of them are spectators.
What if some of my team do not want to act?
Assume some will not, because they will not. Either pick a format with no acting in it, such as a cooperative escape room game where the table works through physical materials together, or make sure your scripted game has genuine non-speaking roles with something practical to do. Do not cast a reluctant person in a talkative part and hope.
Can you run a murder mystery night in a normal office?
Yes, and the two things that matter are seating and light. Break the room into clusters of five or six rather than using one long table, and turn off the overhead fluorescents in favor of lamps. Check your building's rules on candles and on sticking anything to walls before you plan around either.
Is it better to write your own or buy one?
Writing your own is a couple of full days of work once you count making the materials and testing them on somebody, and it will fit your team in a way nothing off the shelf can. If you do not have that time, buy something. The one part you should not improvise either way is the hints, which work best prepared in three levels: what kind of puzzle it is, then the mechanism, then the answer.
How many boxes do we need for the team?
One box per table of up to six, rather than one per person, and that is the detail that changes the arithmetic most. A game is priced per box no matter how many people sit around it, so a team of twenty-four is four boxes and not twenty-four. Add food, and add nothing for decoration if you are willing to move furniture and turn off the overhead lights instead.
