Bridge

Bridge, card game developed from whist. Contract bridge, the form now universally adopted, was perfected by Harold S. Vanderbilt in 1925–26. It is played by 2 pairs of partners, who make bids according to how many tricks (rounds of cards played) they calculate they can win. Demanding great skill, bridge has become immensely popular as a social and competitive game, with international championships controlled by the World Bridge Federation.
