How do I make only my own players sign up for my game?

Playbox has no “members only” or “approve each sign-up” setting for games, and community membership is never checked when someone joins. What works instead:

• Make the game “Private” and share its link only in your own group. Private hides it from Explore and public feeds; anyone with the link can still join.

• Restrict players who signed up and did not come: on their profile, “Ban or restrict”, then “Full ban” or “Online payment only” (they can join but only pay online).

• Participation requirements (approved photo, age, rating range, contacts) filter by profile, not by membership.

Regulars first: set a “Scheduled post” time in the “Publishing” section. Announcements and subscriber notifications go out at that moment, but the direct game link works right away, so send it to your regulars before. There is one publish time per game, not one per chat.
