BIDDING BOXES

Swedish invention permitting silent bidding. Each player, instead of making his bid vocally, takes a card from a complete set of indexed cards held in a small holder and places it in front of him on the table. Bidding boxes have become very popular in duplicate bridge and are universal in tournament play. As well as helping to keep down the general level of noise, they avoid a number of ethical problems since bids are generally made in a uniform manner.
