Team Building Ideas for 50–100 People: Formats That Keep Everyone Involved

Planning team building for ten people is one thing. Planning it for 50, 80 or 100 is a whole different ball game.

The activity still needs to be fun, but suddenly you’re also thinking about queues, team allocation, sightlines, sound, scoring and just how long it takes a big group to get from one room to another. An idea that looks brilliant online can quickly leave half the company standing on the sidelines.

The best team building activities for 100 people aren’t just small-group games with a longer guest list. They’re formats designed to keep lots of teams busy at once, give everyone a clear role and still bring the whole group together at the end.

What changes once you hit 50 people?

At this size, winging it stops working. You can’t assume everyone will hear one set of instructions, find their team or know where to go next, and a five-minute delay repeated across six rotations soon becomes a big hole in the schedule.

Bigger groups also show up any weaknesses in an activity. If a game gives one person a turn while nine teammates wait, a 100-person event creates an awful lot of standing around.

Successful team building for 50 people needs:

• A clear plan for arrival and registration.
• Teams agreed in advance, or a quick way to sort them on the day.
• Plenty of people taking part at the same time.
• Simple instructions, given in more than one way.
• Hosts who can spot when energy or timings are slipping.
• A reliable way to collect scores.
• Space for people to move around without bottlenecks.

By the time you reach 100 people, these details aren’t the finishing touches. They are the event.

Look at how many people are playing, not just how many it holds

A venue might hold 100 guests, and an activity might be available for 100 guests, but neither tells you how many people are actually involved at any one time.

If one setup keeps eight people busy, what are the other 92 doing? If teams rotate, how long is each wait? Can a second or third setup run alongside it, and is that included in the plan?

Watching can be great fun when the activity is designed around a show. It’s less fun when people have been promised team building and spend most of it in a queue. Sketching out the guest journey from arrival to finish quickly shows where people will be playing, moving, resting or just waiting.

Option 1: A Scavenger Hunt with small teams

A Scavenger Hunt splits a big group into smaller teams who tackle clues and creative challenges along a bespoke route.

It works brilliantly for larger numbers because every team is busy at the same time, rather than waiting their turn on one piece of equipment. The route, start and finish can all be planned around your event, and chatting in a small team feels much more natural than trying to get 100 people talking as one group.

There are a few practical things to sort out. The area needs enough space for every team, instructions need to be crystal clear and the finish venue has to be ready for everyone arriving back. Think about mobility, weather and public spaces too, and how colleagues who’d prefer not to do lots of walking can still play a key role.

It’s a great choice when exploring and teamwork suit your goals, but less so if your group needs to stay in one room or the schedule can’t fit an outdoor route.

Option 2: A one-room hosted show

A single-room format takes away the complexity of multiple activity zones. Magic Bingo combines bingo with live magic and comedy, and works for groups from 20 to 500-plus, so it comfortably covers anything in the 50–100 range.

Everyone can stay at their tables, follow one host and share the same experience. It’s a great fit for an evening social, a conference or an event where a more physical activity might put some people off.

You’ll still need to check the room layout, sightlines, sound and table arrangement, though. “Everyone’s in one room” doesn’t help much if someone’s stuck behind a pillar or the back tables can’t hear the host.

It’s also worth knowing that a hosted show creates a different kind of connection to small-team problem-solving. Decide whether you’re after big laughs and a shared atmosphere or more sustained teamwork.

Option 3: A Personalised Quiz

The Personalised Quiz works for 20 to 500-plus guests, using phones and a live leaderboard, with content tailored to your company.

Quizzes scale really well because lots of teams can answer at once, and they give everyone a natural reason to chat while letting different kinds of knowledge shine. Personalised rounds can make it feel like your event, just keep it fun rather than turning it into a test on company policy, and never use questions that put individuals on the spot.

Check the Wi-Fi, screen visibility, sound and phone charging with the venue in advance. If you’d rather go screen-free, the Team Quiz is a technology-free alternative for 20 to 150-plus people.

Option 4: Multiple Giant Jenga stations

The Giant Jenga Challenge works for 20 to 100-plus people, with multiple towers available for larger tournaments.

Running several towers at once keeps teams playing at the same time and creates plenty of easy-to-follow action. Everyone knows the rules, but it still calls for planning, steady hands and a bit of team debate.

Check how many towers and hosts will be included for your group size, think about the floor surface and safe space around each tower, and make sure everyone can reach and move the blocks comfortably. Teammates can take on tactical or supporting roles, but those roles should feel genuinely useful rather than invented on the spot.

Option 5: Ping Pong tournaments running side by side

The Ping Pong Challenge works for 20 to 100-plus guests, using portable tables in an office, function room or outdoor space.

For a big group, the key question is how many matches can happen at once. Ask how many tables, teams and roles will be running side by side.

Ping pong is naturally a bit sporty, so think about the confidence and physical needs of your group. It’s great for teams who want movement and friendly competition, but less suited to a tight venue, a group after something more laid-back or an event where waiting times can’t be kept under control.

Other options that scale well

Crazy Golf is another good option, with extra courses available for larger groups.

The common thread across all of these is simple: to work at scale, an activity either needs several setups running at once or a format where everyone plays together. You can get a feel for how each one looks in action on The Big Smoke Events’ YouTube channel.

How to split 50–100 people into teams

There’s no magic team size. It depends on how many people can do something useful at once. If a task naturally keeps five people busy, teams of twelve won’t make it better.

If connection is the goal, plan teams deliberately. Mix up departments, office locations and how well people know each other, and avoid dropping one new starter into a group of close friends and hoping the activity sorts it out.

Keep it simple to follow. Share teams in advance where it makes sense, display them at registration and have a plan for no-shows. A colour, a number and a clear starting point usually work better than an elaborate team name. And don’t shuffle people around just to make the numbers perfectly even, as access needs and existing working relationships might justify a slightly uneven split.

Keep everyone involved, without everyone doing the same thing

Getting everyone involved doesn’t mean everyone has to do exactly the same thing. A team challenge might need a puzzle solver, note-taker, navigator, timekeeper, performer or tactician, so let people gravitate towards the roles that suit them rather than pushing them into something they’ve said no to.

Share the practical details in advance, like whether there’s movement, phones, loud sound, outdoor time or competitive scoring, and give people a private way to share any access or sensory needs.

Hosts should invite people in rather than pressure them. Watching can be a valid choice, but the format should give quieter colleagues plenty of ways to join in so they’re not automatically left on the edges.

Stop queues before they start

Queue problems usually show up on paper long before the day. For every station or stage, work out:

• How many teams are arriving
• How many people can play at once
• How long playing takes
• Time for explaining and resetting
• Time to move to the next area
• What happens if a group is running late

Staggered starts can help with a route-based event, extra setups can help with station games and one-room formats skip rotations altogether. Each option affects staffing, equipment and space, so check what’s included. And build a small buffer into the running order, because 100 people never move as quickly as the spreadsheet says, especially after a coffee break.

Choose a format that suits your venue

Team building activities for 50 people might fit perfectly in a venue that feels cramped at 100. Look at total capacity and usable activity space separately, as tables, staging, catering, pillars and fire exits all eat into the space you’ve got.

For outdoor events, check the ground, boundaries, public access, shade, toilets and wet-weather plan. For indoor events, test sightlines, acoustics, Wi-Fi and how people will move around. And ask how long setup takes, because a room that’s free for guests at 2pm might not be free early enough for the event team.

Get the competition level right

A leaderboard can create real buzz across a big group, as teams can see how their efforts add up. Keep the scoring simple and decide how you’ll handle a tie. If different stations use different scoring, convert them into one consistent points system.

Competition should add to the atmosphere, not take it over. Think about awards for teamwork, creativity or the best comeback alongside the overall winner, and leave time for people to just chat. Filling every minute with scored tasks can make a generous event feel like a long exam.

Consider a multi-activity event

Team building for 100 people doesn’t have to mean everyone doing one thing for hours. A bigger agenda could combine an icebreaker, food, a main team activity and evening entertainment, and The Big Smoke Events’ event packages are designed to plan and sequence several experiences around your brief.

Mixing it up can vary the energy and give people different ways to get involved, but it also adds more moving parts, like room changes, transitions and supplier responsibilities. Only add variety if it genuinely supports your goal or makes the day better for guests.

Questions to ask before booking

• How many people will be playing at once?
• How many teams and setups are included?
• What will guests be doing at every stage?
• How will instructions reach the whole group?
• How will access and sensory needs be handled?
• What does the venue need to provide?
• Who’s managing registration, scoring and last-minute changes?
• How long are setup and pack-down?
• What’s the backup plan for bad weather or tech issues?
• Which staffing, equipment and personalisation are confirmed in writing?

Plan for 100 individuals, not one crowd

The numbers matter, but even the biggest event is experienced one person at a time. The best team building activities for 100 people have enough capacity for everyone to play, thoughtfully planned teams, no avoidable queues and useful roles for every guest.

If you’re planning an event for 50 people or more, share your numbers, venue and goals through the enquiry page, and The Big Smoke Events team can help compare formats and shape a plan around your group.
