A one-act play is a play that has only one act, as distinct from plays that occur over several acts. One-act plays may consist of one or more scenes. In recent years the 10-minute play known as "flash drama" has emerged as a popular sub-genre of the one-act play, especially in writing competitions. The origin of the one-act play may be traced to the very beginning of drama: in ancient Greece, Cyclops, a satyr play by Euripides, is an early example.[1]
