When selecting from the calendar, if you see less than the maximum number of spots available, that means some spots have already been booked and you will be joining those participants. Bookings will remain open until all spots have been filled. If you would prefer to make your escape with only members of your own party, click on "Private Event" to book the entire game for your group.
Maximum players for each game:
The Family Jewels = 8 Contagion = 8
Area 51 = 10 (12 for private parties)
