This is one of my absolute favorite active group exercises. It sneaks in lessons about teamwork, adaptability, and problem-solving. And it also keeps the energy high and the room full of laughter.
It’s called The Tennis Ball Game. (Or sometimes the Tennis Ball Circuit.) And yes, all you really need is a tennis ball or two (eventually).
Start by dividing your group into smaller teams of about six to eight people. Have each group form a circle with just enough space to toss something across it.
Basic Rules for the Tennis Ball Team Building Game.
The basic rules of the tennis ball team building game are as follows. Hand one tennis ball to a person in each group and explain the objective of the game to them:
Each team competes to complete the most circuits in a given time period.
Here’s how a circuit works:
- Every person in the group must touch the tennis ball once for a circuit to count.
- Once you create a circuit pattern, you must use the same pattern for each circuit.
- Only one person can be in contact with the tennis ball at any given time. That means no handoffs, the ball must be tossed or passed through the air.
- You can’t have people on the team who are standing immediately next to each other touch the ball consecutively.
- If the ball hits the ground, the team must restart the current circuit. For example, if the team gets halfway through circuit nine, and one team member drops the ball, they’d have to start circuit number nine over again. They’d hand the ball to the first person and restart that number.
Once the rules are clear, give teams a few minutes to practice. They’ll start out clumsy and inefficient, but quickly begin to form patterns that make the process smoother.
Here’s the fun part: they’ll naturally begin improving their process without much instruction. That’s the point, teams instinctively improve when faced with a clear goal and a feedback loop (like dropped balls or time limits). Let the team realize this idea themselves before telling them how much better they’ve naturally gotten.
After a Little Practice, Have the Teams Race Each Other.
Once the teams get comfortable and have a good plan, give them a chance to test their plans by starting a race. You can give them a time limit (one or two minutes) to see how many circuits each team can complete. Or, you can make the activity a race to see which team can complete 20 circuits first.
You’d want to pick the version that fits best with the outcome you are looking for. For instance, if you are using this activity as a warm-up for a meeting or a team ice breaker, you’d likely make it a race to see who can complete 20 circuits first.
If you are using the activity to teach the group about teamwork and continuous improvement, you might give them a time limit and debrief the results afterward.
Either way, though, you can repeat the process to make it more challenging (and create more debrief material). The last time I did this with a group, one of the racing teams completed 20 cycles in two and a half minutes. I praised them and congratulated them.
Then, I challenged the entire group to try to complete all 20 circuits in less than one minute. I explained that the fastest group took twice that long in the first round. So, just doing the same thing they did before – faster – was probably not going to work. They’d have to do something different – think outside the box.
I gave them a few minutes to plan and practice just like before. Then we did the activity a second time. Two teams completed all 20 circuits in less than a minute.
It create a fascinating debrief!
This Team Game Is Flexible. So You Can Add Additional Challenges for Specific Business Outcomes.
One of the reasons why I love this team building game is that it is very flexible. And you can create new teaching points by just changing the rules slightly. So, you could shake things up with a few new “real-world” complications. These rule changes help simulate workplace challenges and push the group to adapt their strategies.
A Team Member Calls in Sick
Choose a player from each group to step out of the circle. Announce to the team that their co-worker has called in sick and they’ll need to adjust.
Let them run a few more circuits. You’ll notice something interesting, most groups won’t change anything. They’ll continue passing the ball as if the missing person was never there. But now, the ball is only touching five people instead of six or seven.
Pause the game and ask, “Did you notice that your last few circuits are incomplete?”
This is a perfect moment to highlight a key workplace reality: just because someone is absent doesn’t mean their responsibilities disappear. Someone else has to pick up the slack. Once that lesson clicks, allow the missing team member to rejoin the group.
Double Production
Now for the productivity curveball: introduce a second tennis ball and tell the teams that upper management (you) wants to double production.
At this point, most groups will laugh, then panic a little. That’s okay. The challenge here is maintaining the rule: only one ball per person at a time. Now they have to track two moving objects without colliding, dropping, or breaking their pattern.
Once they stabilize, feel free to add a third or even a fourth ball. The more variables you throw in, the more chaotic and enlightening the exercise becomes.
Observations and Debriefs
This game works incredibly well for reinforcing workplace analogies. Here are a few talking points to use during the debrief:
- Process improvement happens naturally when goals are clear and feedback is immediate. Most teams get faster and more efficient without outside instruction.
- Unexpected challenges test team adaptability. Just like a co-worker calling in sick, or a sudden push to increase output, teams must respond to new constraints without losing sight of the original goal.
- People tend to overlook dropped responsibilities. The missing-person exercise almost always reveals this blind spot. It opens a great conversation about communication and accountability in the workplace.
- Leadership emerges under pressure. Watch for who steps up when things go wrong, and who helps restore order when multiple balls are flying through the air.
Use these observations to guide discussion, connect back to your team’s real-world dynamics, and reinforce the idea that seemingly silly games often carry profound lessons.
Final Thoughts on the Tennis Ball Game
The Tennis Ball Team Building Game is simple to set up, easy to run, and rich with teachable moments. Participants don’t just learn how to pass a ball more efficiently—they discover how communication, accountability, and process design work in real time.
And the best part? They’ll probably laugh the entire way through.
