In response to PaperKonohamaru
When you host the game one of the options it ask you is:

The way your world appears on the hub and pager is affected by the visibility setting you choose.

Public mode is the default. The game will be seen by everyone on the hub.

Private mode means your friends on the pager will see your game. However if they are logged in, it will also be visible on their pager.

Invisible mode prevents the game from appearing on the hub or pager.
