Abstract: Methods, systems, and apparatus, including computer programs encoded on computer storage media, for enabling a virtual lobby. In some implementations, a server receives a request from a first client device to enter a function of a virtual lobby. The server generates a pre-selected number of users to include in the function of the virtual lobby based on a plurality of client devices that opted into the function. The server provides data to each of the pre-selected number of users to indicate an acceptance into the function. The server generates a first communication channel between the first client device and a second client device, wherein the communication channel ensures other users cannot access communications between the first and the second client device. In response to closing the first communication channel, the server generates a second communication channel between the first and the second client device outside the virtual lobby.
