Rooms are removed from the list when the maximum amount of players has joined, and players can filter the rooms by what rules the creator has set, including the battle type ( Stock, Time, or both), whether items are turned on, and whether stage hazards are turned on, as well as whether the creators are friends of the player through MGN. Rooms created can then be joined through a list on the menu, which contains each room's name and creator, as well as the location set in the creator's MGN account settings, how many players can join and have joined the room, the latency setting, and the ping to the server in milliseconds. Players can also set the latency of input delay of the matches, as well as the maximum amount of players that can join the room. Rooms created must contain names of at least four characters, and a password can be added to prevent anonymous players from joining them.

Upon logging in, the player enters the Online Lobby, in which they are allowed to create or join a room for other players to play in.
