Each world has several different terrains and locations. As such, 'world' may refer to a politically or geographically distinct region of land (such as Desert Land or Chocolate Island), a planet, or even an entire galaxy. In general terms, a world refers to any large area of land and space marked off from other regions. 3 was the first Super Mario game to give the worlds distinct names, though some later games return to the standard numerical naming. In earlier games, worlds were simply numbered 'World 1,' 'World 2,' etc. In some three-dimensional Super Mario games, worlds are no longer used now each level stands alone (but each level is sometimes referred to as a world), and the missions are referred to as either stars or episodes. 3, most games have a varying number of levels. 2, each world has three (except the final world, which has only two).

and Super Mario Bros.: The Lost Levels, each world always has exactly four levels, and in Super Mario Bros.
