How do people find your games in Arcade Mode?

Are they all random people who were playing arcade mode or does playing arcade mode put up a lobby for others to join? I have noticed I’m almost always player one in every match I get put with.

as for as i can tell it seems to make you a lobby and you play arcade mode while you wait.

So only people who are manually searching for games in ranked matches will join your game? Arcade mode players aren’t randomly paired with one another then? Is that what you mean?

it seems like it creates a room at first and if that takes to long it will search for an open room.

i could be wrong, iunno.
