World 1-1 (Super Mario Bros.)

World 1-1 is the first level of World 1 in Super Mario Bros. The first screen of the level is also the game's title screen when starting it up. It contains the basics of the Super Mario Bros. game, getting the player ready for the journey ahead. The level features Magic Mushrooms, standard enemies such as Little Goombas and Koopa Troopas, a lot of coins, a hidden secret bonus area that allows the player to skip most of the level, Fire Flowers, pits, and a flagpole at the end. According to Shigeru Miyamoto, World 1-1 was one of the later levels to be created, due to the "fun" courses created first being more suited for later in the game when players are more familiar with how the game works. Like all levels in Super Mario Bros., it returns in Super Mario Bros. 35, where it is known as Course 1-1.

Layout
This level starts out on a flat, open path. As Mario or Luigi moves forward, a Little Goomba appears and starts walking towards them. They then reach the first ? of the game, and afterward the six block triangle formation of ?s and regular bricks (with a Magic Mushroom inside the left block). A set of Pipes can be found, with Little Goombas located in between them. The final pipe among the set leads to a bonus area of coins and can be entered to bypass much of the level. After that, assuming the pipe was not taken, there is a hidden 1 up Mushroom block and a pit followed by another ? containing an item, possibly a Magic Mushroom or Fire Flower, depending on the their form. Additionally, Little Goombas start falling down from a long row of blocks above. There is a brick down below contains ten coins that the plumbers can retrieve by jumping repeatedly underneath the brick. There are two bricks after that; the second one contains a Starman. Then there is a ? triangle formation. The top block contains a Fire Flower (or a Magic Mushroom if Mario is small). A Koopa Troopa and more Little Goombas appear. Bricks and ?s can be found, followed by a pyramid-like set of Hard Blocks with a gap in the middle. After that is another pyramid-like set of blocks, this time with a pit in the middle. Just following is another pipe that cannot be entered (which is the exit from the bonus area mentioned earlier), followed by two Little Goombas and four blocks in a row (three bricks and a coin-holding ?). Afterwards is another inaccessible pipe, the ending staircase for the level, and the flagpole, which is reused in all underground and underwater stages in the game.
