Team building has a bit of a reputation.
Mention it at work and some people immediately picture trust falls, forced icebreakers or standing in a conference room trying to think of an interesting fact about themselves.
It doesn't have to be like that.
The best team building activities give colleagues something genuinely enjoyable to do together. The teamwork happens naturally because people are trying to solve a problem, create something, compete in a challenge or simply have a good time as a group.
Indoor activities are particularly useful because they don't depend on the weather and can often be organised directly at the office, in a conference venue or as part of a company kick-off.
Here are 20 indoor team building activities that can work for everything from a small office team to a larger company event.
1. Solve a Murder Mystery
Give the team a fictional crime and see if they can solve it.
An investigation-style murder mystery can work particularly well for team building because colleagues have to examine information, discuss different theories and eventually agree on what they think happened.
The evidence might include police reports, suspect interviews, photographs, messages, maps and other documents. Different people naturally notice different things, which means the team needs to combine its observations to understand the case.
For a larger company event, participants can be divided into smaller investigation teams and given the same case. Each team investigates independently before submitting its final theory.
That turns the mystery into a competition without requiring anyone to perform, exercise or stand in front of their colleagues.
If this sounds like the right format for your team, we've put together a separate guide to murder mystery team building, including how to divide participants into teams and organise the investigation.
2. Office Escape Room
An escape room gives a team a series of puzzles and challenges that must be solved within a limited amount of time.
You can visit a physical escape-room venue or create a simpler version in the office using boxes, locks, clues and puzzles.
The format naturally encourages communication because information is often distributed across several challenges. One person might solve a numerical puzzle while someone else notices a hidden clue that connects everything together.
For larger companies, divide participants into several teams and compare completion times.
3. Build the Tallest Tower
Give each team exactly the same materials and ask them to build the tallest freestanding tower possible.
The materials can be deliberately simple: paper, tape, straws, spaghetti, cardboard or whatever you have available.
Set a time limit and establish a few basic rules before starting. For example, the tower must stand independently for at least ten seconds and cannot be attached to the table, wall or ceiling.
It sounds simple until everyone starts disagreeing about structural engineering.
That's part of the point.
4. Run an Office Quiz
A quiz is easy to organise and works with almost any group size.
Instead of relying entirely on general knowledge, mix several categories. Include music, films, geography, visual questions, company-related trivia and perhaps a few questions submitted anonymously by colleagues beforehand.
Teams of around three to five people allow everyone to contribute without making the groups unnecessarily large.
The quiz doesn't need to last an entire afternoon either. A focused 30–45 minute competition can work well between meetings, before dinner or at the end of a company conference.
5. Try a Blind Drawing Challenge
Divide everyone into pairs and give one person an image that the other person isn't allowed to see.
The first person has to describe the image without explicitly saying what it is, while their partner attempts to draw it based entirely on those instructions.
Compare the original image with the final drawing when time runs out.
The results are usually terrible.
Fortunately, that's exactly what makes the activity entertaining.
It's also a simple exercise in communication: giving instructions that seem perfectly clear to you doesn't necessarily mean another person interprets them in the same way.
6. Create a Mini Office Olympics
Turn several small challenges into one larger competition.
You might include paper-plane distance, cup stacking, desk-chair curling without the actual curling, memory challenges, throwing paper balls into a basket or other harmless activities that can be completed indoors.
Divide colleagues into teams and award points for each event.
The advantage is variety. Someone who has absolutely no talent for throwing a paper aeroplane may suddenly become extremely valuable when the memory challenge begins.
Keep the events short so the afternoon moves quickly and nobody spends twenty minutes waiting for another team to finish.
7. Hold a Creative Problem-Solving Challenge
Give each team the same hypothetical problem and ask them to develop a solution.
It could be serious:
“How could we improve the first week for a new employee?”
Or deliberately ridiculous:
“Your team has been selected to establish the first office on Mars. What ten things are you bringing?”
Give everyone a limited amount of time and ask each group to present its solution afterwards.
The quality of the presentation matters less than the discussion that happens while the team tries to agree on an answer.
8. Have a Cooking Competition
If you have access to a suitable kitchen or event venue, divide colleagues into teams and give everyone the same culinary challenge.
That could mean making pizzas, decorating cakes, creating the best tacos or preparing a dish from a limited selection of ingredients.
Cooking gives teams plenty of small decisions to make together without feeling like a formal teamwork exercise.
Just make sure dietary requirements and allergies are handled before the activity begins.
And perhaps don't let the accounting department decide that presentation deserves 80% of the scoring criteria simply because their pizza is inedible.
9. Try a Puzzle Race
Give every team an identical jigsaw puzzle and see who can complete it first.
For an additional challenge, mix a few pieces into separate envelopes that can only be opened after the team completes another small task.
This turns an ordinary puzzle into a more structured competition.
It also gives teams an opportunity to organise themselves. Some people start sorting edges, others organise pieces by colour and somebody inevitably insists they have a revolutionary strategy before doing something everyone else was already doing.
10. Organise an Indoor Scavenger Hunt
Hide clues or objects around the office or event venue and create a route that teams need to follow.
Each clue should lead to the next location or require the group to complete a small challenge before continuing.
You can make the hunt company-themed by incorporating familiar rooms, inside jokes or information about the organisation, but make sure newer employees aren't disadvantaged by requiring years of company knowledge.
For larger groups, give teams slightly different starting points so everyone isn't running toward the same cupboard at once.
11. Play Two Truths and a Lie – With a Twist
The classic version is simple: everyone shares three statements about themselves and the group guesses which one is false.
For established teams, make it more interesting by collecting the statements beforehand and turning them into a team competition.
Read three facts without revealing whose they are. Teams first have to determine which colleague the statements describe and then identify the lie.
This works particularly well when people already know each other reasonably well but may not know much about their colleagues outside work.
Keep participation voluntary and avoid questions about personal topics people may not want to discuss.
12. Build Something With LEGO
Give each team the same selection of bricks and a challenge.
Build the ideal office.
Create a model representing the company's future.
Construct the strongest bridge.
Or simply give everyone a strange object they need to reproduce from memory.
The physical nature of the activity makes it accessible without requiring complicated instructions, while the open-ended challenges encourage teams to discuss, plan and divide tasks.
The final models also give everyone something to compare afterwards.
13. Hold a Team Debate
Give teams a harmless subject and randomly assign which side they need to defend.
For example:
Is breakfast food better than dinner food?
Should meetings longer than 30 minutes be illegal?
Would you rather work from a beach or a mountain cabin?
Give each team ten minutes to prepare its arguments and then hold a short debate.
Because the subjects aren't serious, people can focus on building an argument together rather than worrying about whether they personally agree with the position.
Avoid political, religious or otherwise sensitive topics. The objective is collaboration, not creating a workplace crisis for HR.
14. Create a Collaborative Story
Start with a simple premise and ask the group to build a story together.
Each person adds a sentence, paragraph or new development before passing the story to someone else.
For larger teams, divide everyone into groups and give each group the same opening line. After fifteen minutes, compare how completely different the stories have become.
You can also introduce random words or objects that every team must somehow incorporate.
It's a low-pressure activity that works particularly well as a shorter session between more structured parts of a company event.
15. Try a Codebreaking Challenge
Create a series of ciphers, hidden messages and logic problems for teams to solve.
Each solved puzzle reveals information needed for the next stage until the group reaches a final answer.
The activity can be as simple or elaborate as you want. A few printed sheets may be enough for a 30-minute challenge, while a larger collection of interconnected puzzles can become the main activity for the afternoon.
Codebreaking tends to reward different ways of thinking, so encourage teams to pass puzzles around rather than allowing one person to become permanently stuck on the same problem.
16. Run a “Guess Who” Colleague Challenge
Before the event, ask participants to submit an unusual but appropriate fact about themselves.
Perhaps someone has appeared on television, competed nationally in a sport, visited 40 countries or once accidentally met a celebrity in an airport.
Read the facts one at a time and let teams guess which colleague each statement belongs to.
The activity gives people natural conversation starters afterwards without forcing anyone to answer personal questions on the spot.
Again, participation should be optional and submitted facts should be screened before the event.
17. Give Teams a Design Challenge
Provide a problem and a limited selection of materials.
Teams might need to build a bridge capable of supporting a certain weight, create protective packaging for an egg or design a paper vehicle that travels as far as possible.
The limited resources force people to make decisions together.
Should they spend most of the available time planning or start building immediately? Should everyone work on the same design or test several ideas first?
The final test creates a clear ending and usually produces enough failed engineering to keep everyone entertained.
18. Host a Team Game Tournament
Instead of choosing one game, create several short stations.
Teams rotate between activities such as trivia, drawing, word games, logic puzzles and physical tabletop challenges. Award points at each station and combine the results at the end.
This works particularly well when you have a mixed group because success doesn't depend on one particular skill.
It also keeps the pace moving. If someone dislikes one activity, the next one starts shortly afterwards.
19. Create a Mystery Box Challenge
Give each team a sealed box containing several strange objects, documents or clues.
Their task is to work out what connects everything.
Perhaps the objects tell the story of a fictional person. Maybe they reveal a location, password or hidden message. You can make the challenge entirely logical or deliberately strange.
Unlike a traditional quiz, there isn't necessarily an obvious starting point. Teams need to examine what they have, share observations and decide which information matters.
That uncertainty is what makes the challenge interesting.
20. Let the Team Choose the Challenge
Sometimes the easiest way to avoid awkward team building is to give people some control over what they're going to do.
Before the event, present three or four options and let employees vote anonymously.
For example, they could choose between a murder mystery investigation, cooking challenge, office tournament or creative workshop.
You still organise one shared activity, but the group has had some influence over the decision.
That's particularly useful if your company has tried several different team building activities before and you're unsure what people would actually enjoy.
What Makes a Good Indoor Team Building Activity?
The best activity depends on the people taking part.
A highly competitive sales team might enjoy a tournament with points and prizes, while another workplace may prefer something cooperative where everyone works toward the same objective.
Group size matters too. An activity that works brilliantly for eight colleagues may become chaotic with 60 participants unless it can be divided into smaller teams.
You should also consider how much preparation is required, how long the activity will take and whether everyone can participate comfortably. Physical ability, accessibility, language and how well colleagues already know each other can all affect which activity is appropriate.
Most importantly, don't confuse discomfort with successful team building. People don't need to be embarrassed or pushed dramatically outside their comfort zones for an activity to encourage communication.
Indoor Team Building for Small Teams
With a small team, you can choose activities where everyone works together rather than dividing participants into competing groups.
A murder mystery investigation, escape-room challenge, cooking activity or collaborative problem-solving exercise can all work well because every person has room to contribute.
Smaller teams also make discussion easier. If six colleagues are solving a fictional crime together, everyone can hear the theories and examine the evidence without needing a complicated structure.
For very small groups, choose an activity where the number of participants doesn't create a disadvantage.
Indoor Team Building for Larger Groups
Large groups usually work better when divided into smaller teams.
The key is choosing an activity that can be replicated. Quizzes, puzzle races, design challenges and murder mystery investigations all allow several groups to complete the same challenge simultaneously.
For example, a company with 24 participants could create six teams of four and let every team investigate the same fictional murder case. Once time is up, everyone submits their solution and the real answer is revealed.
This creates a shared company activity without requiring all 24 people to participate in one conversation.
Team Building Without Awkward Icebreakers
You don't necessarily need an icebreaker at all.
Give people something interesting to solve, build or create and conversation usually starts because the activity requires it.
That's one reason problem-solving activities work particularly well. Instead of asking two colleagues who barely know each other to “network”, give them a suspicious interview transcript and ask whether they think the suspect is lying.
Now they have something to talk about.
The same principle applies to escape rooms, cooking challenges, scavenger hunts and design competitions. A shared objective removes much of the pressure of having to manufacture social interaction.
How Long Should an Indoor Team Building Activity Be?
A short activity can take 20–30 minutes, while the main event of a company kick-off might comfortably occupy two or three hours.
Match the length to the purpose.
If team building is a break during a conference, a short quiz, drawing challenge or puzzle works well. If it's supposed to be the main social activity of the day, choose something with enough substance to keep people engaged.
Also allow time for instructions, forming teams and wrapping up afterwards. A 90-minute activity rarely occupies exactly 90 minutes on the schedule.
Turn Your Team Into Investigators
If you want an indoor activity built around communication and problem-solving without requiring acting or awkward introductions, a murder mystery investigation is one option worth considering.
Ink & Clues creates downloadable murder mystery cases where participants examine police reports, interviews, photographs and other evidence to determine what happened. The regular investigations are designed for 1–6 players, can be printed or used on screen, and individual cases generally take around 1–2 hours, depending on the case and group.
For a company event with more participants, smaller teams can investigate in parallel, provided the intended use is covered by the relevant licence. The dedicated Murder Mystery Team Building guide explains the setup in more detail.
If you need something for a genuinely large group rather than several small investigation teams, Ink & Clues also has Murder at the Grimoire Hotel, a separate roleplaying murder mystery party designed for 8–30 players.
Whether you choose a murder mystery, an escape room, a cooking competition or something completely different, the basic principle is the same: give people a reason to work together and let the interaction happen naturally.
