Yes. You can make a Daily tournament Invite Only.
If you are asking about Live, you can create club tourneys and only members of the club can be in them (though they are Swiss events, not round robin). Just turn off the option that anyone can join and only approve your friends.
Hi,
Is it possible to set up a private tournament here? I have several friends at work that play and we wanted to have a little round robin tournament among ourselves.
Thanks
