Invite friends and family for a evening filled with fun. Have everyone bring 3 gifts of an agreed amount of say $5. Place the wrapped gifts on the table on arrival as anonymous as possible. Agree on a duration on forehand and set this in the app. The default is 45 minutes. The app keeps track of time and lets you know when it's over. The first person (for example the oldest) starts shaking the phone. The app provides an assignment that has to be performed. After performing the task, the phone has to be passed to the next person. This person now shakes and performs the assignment. Keep repeating this until time is up. If time runs out, the gifts may be unpacked.
