Bridge & other card games/Bridge rotation for 12 couples (Teams) including hosting

Advertisement


Question
We have a bridge Group and we meet once a week for 8 weeks and then we meet the 9th week for an Awards Luncheon and announce the winners.  We have 12 couples (teams) and each team should host only 4 times over the 8 weeks
WOULD YOU PLEASE SEND ME A ROTATION for a 12-couple set up? We play one table @ 6 houses each week. Unlike the question answered for Joyce for 9 games we also need to indicate who is to host each game such that each couple (Team) hosts only 4 times. Thank You for your assistance.      Ron

Answer
Here is the answer that I gave to Joyce over an 8 week period. Below that is a suggestion for the host pair. While it is not evenly spaced over the 8 weeks (some pairs host more near the beginning and others host more near the end), every pair ends up hosting exactly 4 times.

I can answer questions on bidding and on cardplay with the caveat that the former may necessarily involve some subjectivity. I have been playing tournament bridge for over 20 years and I have won several regional tournaments.
