Duplicate bridge is the most commonly played variation of the trick-taking card game contract bridge. In duplicate bridge, the same bridge hand or arrangement of cards is used at every table and is scored based on each player's relative performance.
With duplicate bridge, every bridge hand, strong or weak, is played with others playing the same cards, which heightens the element of skill while reducing the element of chance. In another variation of contract bridge, called rubber bridge, each hand is freshly dealt and scores tend to be more affected by chance.
Most of the bridge played today in clubs, tournaments and online in the United States and Australia is duplicate bridge, while rubber bridge remains popular in homes and clubs in the United Kingdom.
