Simple networking game

How to create a simple get to know each other indoor game using Loquiz that works well indoors?

The game is very simple. You go to the person, scan their name badge and get a task. Fulfill the task with the help of that person and move on. Simplest tasks are questions, but you can go wild, of course. You can use T-shirts and print QR codes on them instead of name tags. TRUE-FALSE questions work best because they are simple and quick. Good for the flow. Also, finding the TRUE fact within several FALSE ones also works wonders.

Preparation includes getting some information from all the participants, printing QR codes on name badges and for the players to install and start Loquiz application.
