Picking a station.
Up to 8 players, each on their own phone, all on the same wifi. One device hosts and shows a code; everybody else joins with it.

Devices connect straight to each other, so they have to be on the same network: the same wifi, or a hotspot from one phone that the others join. Some hotel, school and office wifi blocks this; a hotspot gets round it. PeerJS's free server introduces the devices and sees their IP addresses, never the game.
