2. Put the desired kegs in the bag.
3. Everyone randomly takes one barrel (with a number) and does not show it to anyone.
4. According to the map (they are the same for everyone) - he gets his role.

Answer 2

Bluetooth is not very suitable for group chats, at least before it was impossible to gather more than 2 people. And a bluetooth-based network is a rather difficult task that is far from feasible on any phone.
Better than any regular network chat + organizer in wifi hotspot mode.
