Social bridge can be arranged at clubs:
You and your friends can book a table, for a session, and play up to 32 boards, at the clubs listed below. These are hosted games, in the sense that they are organised by the club manager, at set times.
Your game is just for you and your friends. You can arrange to swap partnerships or players. The table is there for your party. At any moment in time there can only be 4 persons at the table.
