The Best Large Group Indoor Games for Adults That Actually Work
Large group indoor games for adults aren’t just a way to pass time when the British weather ruins your plans.
They’re one of the smartest ways to bring colleagues together, cut through awkward silences, and inject some energy into your company culture.
If you’re a PA, HR manager, or unlucky volunteer tasked with organising a team day, you need games that actually work — not ones that flop after five minutes.
So, let’s break down which games deliver results, why they matter, and how to avoid the dreaded eye-roll from your colleagues.
Why Large Group Indoor Games for Adults Matter
When you’re dealing with 30, 50, or even 200 people, the wrong game can create chaos.
The right one, though, can transform the atmosphere.
Studies show that companies with highly engaged employees see a 21% increase in profitability and a 17% boost in productivity (Gallup).
That’s not just a stat — it’s proof that a quick-fire game of Human Bingo or a fully facilitated event like Escape the Box can make your team feel more connected, valued, and ready to perform.
Beyond the numbers, large group indoor games for adults help dissolve barriers.
It’s hard to keep your corporate mask on when you’re lip-syncing to Britney Spears or frantically trying to balance spaghetti and marshmallows.
How to Choose Indoor Games for Large Groups
Not all large group indoor games for adults are created equal.
Before you dive in, ask yourself a few questions:
-
Space: Do you have enough room to run around, or is it a boardroom setting?
-
Time: Do you want a 10-minute icebreaker or a 90-minute immersive challenge?
-
Goals: Are you trying to spark laughter, improve collaboration, or practise problem-solving?
-
Audience: Is this a team of interns who love chaos, or a board of directors who’d rather not crawl on the floor?
Once you’ve answered these, you can narrow down your list.
For example, trivia or Human Bingo works for limited space, while high-energy relay charades need room to move.
Professional events from a team building company like Zing are scalable and designed to run smoothly even with 200 people, saving you stress and second-guessing.
Quick Icebreakers for Big Groups
Large groups can feel overwhelming at first, so icebreakers are your best friend.
Human Bingo is a classic. Give everyone a bingo sheet with quirky facts like “has run a marathon” or “can juggle.” The first to fill a line wins. It’s simple, low-cost, and brilliant for networking-heavy away days.
Two Truths and a Lie (Mass Edition) works brilliantly indoors with no props. Everyone shares three statements about themselves, and the room guesses the lie. It’s a guaranteed laugh, especially when you discover your boss once auditioned for The X Factor.
For conferences with minimal time, try Speed Networking. Pair people up for two minutes to answer a silly question, then rotate. You get the energy of a room buzzing within minutes.
Creative Indoor Games for Adults
When you want something that pushes creativity, there are great options for large groups.
Animate, facilitated by Zing Events, lets teams bring stories to life using stop-motion animation. It’s fun, hands-on, and brilliant for sparking imagination while still being structured.
Lip Sync Battle is another crowd-pleaser. Split into teams, pick songs, and perform with full commitment. It works brilliantly as an evening add-on to a company conference or as a way to shake off the afternoon slump.
Story-Building Relay is a simple DIY game: one person starts a sentence, the next adds to it, and so on. The results are often hilarious and surprisingly insightful about how teams collaborate.
Problem-Solving Games for Large Groups
These are perfect if you want to sharpen collaboration and critical thinking.
Escape the Box, a Zing Events classic, is like an escape room brought directly to your venue. Teams crack codes, solve riddles, and race against the clock. It scales from 30 to 200 people indoors, which is why it’s become a go-to for corporates.
Marshmallow Tower is another popular choice. Hand out spaghetti and marshmallows, then ask teams to build the tallest structure. It looks like child’s play, but watch the competitive streaks emerge.
If you want something with more pressure, try Trading Floor, where teams buy, sell, and trade in a high-pressure stock market simulation. It’s loud, frantic, and surprisingly good for bringing out leadership qualities.
High-Energy Indoor Games
Sometimes you need to raise the roof, even indoors.
Squid Play Game Show, inspired by the hit series but much safer, pits teams against each other in tense, competitive, and often hilarious challenges. No one gets eliminated, but everyone gets stuck in.
Relay Charades is another high-energy option. One person acts out a word, the next guesses, then runs to act out the next clue. It’s simple but chaotic in the best way.
Deceivers, Zing’s version of The Traitors, works brilliantly indoors for large groups. Teams must spot the liars among them through deduction and intuition, creating psychological gameplay that sparks plenty of banter.
Charity Indoor Games That Give Back
Why not use your large group energy for good?
Activities like Putt a Hole in Hunger or Food Chain combine fun with social impact. Your team bonds while supporting food banks or local charities.
Charity Challenge is another powerful indoor activity where teams solve tasks that ultimately contribute to a cause. It’s meaningful, fun, and leaves your colleagues with something more than just good memories.
With more organisations focusing on CSR, these games tick both boxes: team bonding and giving back.
DIY vs Professional Facilitation
Here’s a quick comparison to help you decide whether to run your own or call in the experts:
| Option | Pros | Cons | Best For |
|---|---|---|---|
| DIY Games (e.g. Human Bingo, Trivia) | Cheap, quick, easy to set up | Risk of chaos, limited impact for 50+ people | Small budgets, casual settings |
| Professional Team Building Activities (e.g. Escape the Box, Animate, Squid Play) | Seamless facilitation, big impact, scalable for 200+ people | Cost involved | Large corporate groups, conferences, high-stakes events |
If you’re in London, working with a team building company like Zing means you don’t have to worry about logistics, equipment, or whether your CEO will actually join in.
Professional facilitation ensures everyone is engaged, the activity flows, and the outcomes match your goals.
Large Group Indoor Games That Work for Conferences
Conferences can be a tough crowd. You need activities that engage people quickly and can run in hotel ballrooms or office spaces.
Trading Floor, mentioned earlier, is perfect for high-energy simulation.
Deceivers Game Show, inspired by The Traitors, is another conference-friendly option. It’s strategic, fun, and easy to scale.
For something light-hearted, No Ordinary Quiz or Musical Bingo are evening options that get everyone talking without draining energy.
The Zing Show is another standout evening option, combining elements of TV game shows into one high-energy event.
Why Indoor Games Are Perfect for London Teams
London offices don’t always have the luxury of outdoor space, so large group indoor games for adults are a lifesaver.
Whether you’re running something at a venue like The Brewery, a conference centre, or your company HQ, indoor games are weather-proof and easy to adapt.
This is why many organisations searching for team building activities London end up choosing indoor formats. They’re flexible, scalable, and suit both budget-friendly and high-end events.
