How are rooms created for multiple (5) random players?

Question

Programming

I want to play with node.js, write a small application (game).
Can anyone explain how rooms are created for multiple (5) random players.
For example, I press the search for a game and it connects me to the X room in which the largest number of players is < 5/.

Answer 1

You do not understand how to scatter the players in the rooms or how to make the actual rooms?
