We did something similar for our workplace GooseChase and found that the best missions were the ones that mixed teamwork with a little silliness. A few hits were "Office Music Video," where teams picked a random song and filmed a quick lip-sync, "Build the Tallest Tower," using only office supplies, and "Guess That Baby Photo," where everyone submitted an old picture and teams had to match them up. We also threw in a "Random Acts of Kindness" mission-like leaving a funny sticky note for someone-which balanced the humor with a feel-good twist. The mix of creative and collaborative tasks really got everyone engaged, and seeing the photos and videos come in through GooseChase had the whole team cracking up the rest of the day.
