Some training activities never fail to engage a group, no matter the context, culture, or organizational hierarchy. One of my absolute favorites is the Lockbox activity, a collaborative puzzle-solving challenge that brings teams together in a fun, high-energy way.
I’ve used this activity in executive team retreats, to bring merging organizations together, and most recently, as part of an organizational values workshop abroad. Each time, it delivers powerful lessons in teamwork, communication, and leadership—all while keeping every single participant fully engaged.
How the Lockbox Activity Works
The setup is simple but effective:
- Participants are split into small groups.
- Each group receives puzzle pieces and a locked box.
- Their goal is to assemble the puzzle, which reveals a number combination needed to open the lockbox.
- Inside the box is a surprise—often an item that ties into the training’s broader purpose.
It sounds straightforward, but the magic happens in the depth of teamwork, communication, and collective “aha!” moment when a team cracks the code.
Why I Love The Lockbox Activity
Nobody’s Just Sitting Back
Unlike some exercises where a few voices dominate, this activity ensures everyone is involved. Whether they’re sorting puzzle pieces, testing number combinations, or just hyping up the team, everyone gets pulled into the action. No wallflowers allowed.
Hierarchy Disappears
I’ve run this activity everywhere from Seattle to Delhi to Oaxaca, with teams that have strict power structures and those with shared leadership. But once that timer starts? Job titles vanish. The quiet intern might have the breakthrough idea. The CEO might be the one frantically shuffling puzzle pieces. Teams quickly realize that success hinges on every member contributing ideas, making it a beautiful, chaotic equalizer.
Pure, Unscripted Joy
There’s nothing quite like the moment a team finally unlocks the box. Whether they’re the first or last to solve it, the cheers, high-fives, the sheer relief—it’s 100% authentic and contagious. Even the “serious” folks can’t help but get swept up in it.
A Debrief That Fits Any Objective
The discussion afterward is where the real learning happens. Depending on the training goal, I’ve kept debriefs short (10 minutes) or let them run deep (over an hour). We’ve explored:
- Leading without authority
- Communicating under pressure
- How different thinkers crack problems differently

The versatility makes it perfect for team-building, leadership development, or just breaking the ice in a big way.
Bringing the Lockbox Activity to Your Team
If you want an activity that’s equal parts fun and insightful, I recommend giving the Lockbox activity a try. Use it to bring your values to life, level up your team’s leadership game, or just get everyone laughing and working together. Either way, people will be talking about it long after the session ends.
