Bridge (game), one of several related card games played by four people with a deck of 52 cards. Two of the players are partners competing against the other two. The term bridge alone is generally used today as an abbreviation for contract bridge, which virtually has displaced other forms of the game. All bridge games stem from whist . Bridge whist, the original variation, was introduced in England late in the 19th century.

In all forms of bridge, 13 cards are dealt to each player. One of the players declares which of the four suits shall be trump (making the 13 cards of that suit higher in rank than the other 39 cards) or declares that there shall be no trump. The method of declaration varies with the form of bridge. The player to the left of the declarer then leads a card. Each of the others in turn plays a card and must play a card of the suit led, if possible. The 4 cards played constitute a trick, which is won by the person playing the highest card of the suit led, or the highest trump if any trump has been played. The winner of the first trick leads the first card of the second trick, and so on for the remainder of the 13 tricks. The scoring depends primarily on the number of tricks won by each side and is different for the different forms of bridge.

I. Auction Bridge

In auction bridge the players bid against one another for the right to declare the trump suit; each bid is an undertaking to win the specified number of tricks, and the winner of the auction is penalized if he or she does not make the bid. Auction bridge was developed in the early 1900s and by 1910 had almost completely replaced bridge whist.


In auction bridge penalty points and bonus points are scored above the line, which means they are not counted toward game; points are scored below the line only by the side winning the auction and only if it makes at least as many tricks as bid. No score is accumulated for the first six tricks; each additional trick counts 6 points if the trump suit is clubs, 7 points if diamonds, 8 points if hearts, 9 points if spades, and 10 points if there are no trumps. A total of 30 or more points below the line completes a game; the first side to win two games completes the rubber and gets a bonus of 250 points. At the conclusion of each rubber the scores are totaled without distinction between points below or above the line.

Penalties for failure to make a contract -that is, the number of tricks bid-are awarded to the defending side as bonuses and amount to 50 points for each undertrick. If the contract has been doubled by the defenders, the penalty is 100 points for each undertrick; if redoubled by the bidding side, the penalty is 200 points. If a doubled contract has been made, the side that made the bid scores double the trick value below the line, plus a bonus of 50 points for making the bid, plus an additional bonus of 50 points each for any overtricks. Corresponding redoubled scores are four times the trick value; 100 points for contract; and 100 points for each overtrick.

Bonuses are given for the holding of honors (the five highest cards of the trump suit, or the four aces if there are no trumps). If one side holds three honors, it scores 30 points; four honors, 40 points; five honors, 50 points. Four trump honors in one hand and one in the partner's hand count 90 points, and all the honors in one hand count 100 points. Bonuses are also awarded for slams; 50 points for a small slam -that is, for taking 12 of 13 tricks-and 100 points for a grand slam, which requires taking all 13 tricks.

II. Contract Bridge

In contract bridge the scoring places an emphasis on skillful bidding. The bidding and play in contract bridge are identical with those in auction bridge, but the techniques are different because of the difference in scoring. The bonuses that are awarded for rubber or for slams encourage bidding the full value of the hands as dealt; however, the penalties for failure to make the bid, especially if doubled, are so severe as to evoke extreme caution against overbidding. Bidding techniques have been developed to such an extent that experienced bridge players rarely fail to contract for games or slams that have a reasonable chance for success.

Bidding in contract bridge begins with the dealer and continues, with a pass, bid, double, or redouble, until the auction closes. A bid is an offer to win a number of odd tricks (tricks in excess of six, with the first six tricks known as the book ) with a named trump suit, or with a bid of no trump. For example, a bid may consist of "two hearts" or "one no trump." Each subsequent bid must overcall (be greater than) the preceding bid. An overcall requires bidding a higher number of odd tricks or, if bidding the same number of tricks, specifying higher-ranking cards. Cards rank as follows (from high to low): no trump, spades, hearts, diamonds, and clubs. A player may double (increase the scoring value) the preceding bid if that bid has not been previously doubled. If the preceding bid has been doubled the next player may redouble the bid, further increasing the scoring value of the trick. The auction closes when three consecutive passes follow a bid, double, or redouble, and every card of the suit named in the final bid becomes a trump. If the final bid is no trump the cards are played without a trump suit. The member of the partnership that specified the suit or no trump in the final bid becomes the declarer, and the number of tricks specified in that final bid becomes the contract the declarer must fulfill when play commences.

Contract bridge was developed about 1925, and by 1930 had almost completely replaced auction bridge. Its popularity has become so great that millions of people currently play the game and thousands of professional bridge experts teach it.


In contract bridge only those tricks bid and made are scored below the line; overtricks are scored as bonuses. The first six tricks are not counted; each additional trick in clubs or diamonds counts 20 points; in hearts or spades, 30 points; and in no trump, 40 points for the seventh trick and 30 points for each additional trick.

A total of 100 points below the line is required for game. A side is not vulnerable at the beginning of each rubber and becomes vulnerable after making one game. The first side to make two games collects a rubber bonus of 700 points for a two-game rubber or 500 points for a three-game rubber.

Honor bonuses are given only for honors all in one hand. Four honors in a suit are worth 100 points; five honors in a suit, or four aces in a no-trump contract, are worth 150 points. Bonuses for slams are given only for slams bid and made. A small slam yields 500 points if the bidding side is not vulnerable, 750 points if vulnerable. The corresponding bonuses for grand slams are 1000 and 1500 points. An additional bonus of 50 points is awarded for making a doubled contract, and 100 points is awarded for a redoubled contract.

Penalties for undertricks are scored as bonuses by the defending side and are assessed at 50 points per undertrick not vulnerable and 100 points when vulnerable. Doubled contracts double the value of the first undertrick and increase successive undertricks at a rate of 200 points not vulnerable for the first three tricks, 300 points not vulnerable thereafter, and 300 points vulnerable. Redoubled penalties are twice the doubled value.

Bridge in Pakistan

Duplicate Bridge was introduced in Pakistan in 1957 by a civil engineer Kh. Azeemuddin, the founder and Managing Director of Associated Consulting Engineers (ACE) private limited. He, with the active support of his colleagues Ashfaq Ahmed, Qavi Khan, Mahmood Ali and Kadir Ali founded the 57-Club at the Nazimabad Club, Karachi. Other such organisations also sprung up and they joined hands to popularise the game. Late Muhammad Tasnim and Dr. R.H. Usmani organised tournament to give boost to the game. No rules had been formulated - that time but their verdict was accepted by all.
