Running bridge for 12
For 12 players you will need 3 tables, 3 decks of cards, and 3 sheets of paper for the score cards (four to a page).
Give each guest a number. Partners sit across from each other at the table the chart shows. Many party-bridge groups play four deals a round, Chicago style, so every round has a fair mix of vulnerability, then write the score on each card and move.
Each score card lists that player's table, partner and opponents for every round. Want names on them, a different number of rounds or a fresh shuffle? Open this chart in the planner.
