World 1 (Super Mario Bros.)

World 1 is the first world of the Mushroom Kingdom in the game Super Mario Bros.

World 1-1
The unforgettable original World 1-1 from Super Mario Bros. is the first level played, and likely memorized, by many Mario fans. This level has been re-created in many games, both fan games and official games alike.

World 1-1 contains the basics of the Super Mario Bros. game, getting the player ready for the journey ahead. The level consists of Super Mushrooms, standard enemies such as Goombas and Koopa Troopas, a lot of Coins, a hidden secret bonus area, Fire Flowers, deadly gaps, and a flagpole at the end.

Description
World 1-1 starts out on a brick path, possibly a path that was once a walkway in a town of the Mushroom Kingdom before King Bowser's violent coup. As Mario moves forward, a Goomba appears and starts walking toward Mario. The red-clad plumber also reaches the the memorable first ? Block and then the six block triangle formation of ? Blocks and regular Brick Blocks (with a Super Mushroom inside the left block). A set of Pipes await Mario with Goombas located inbetween the plumbing. The final pipe among the set leads to a bonus area of coins and can be entered to warp through the level. After that, there is a gap followed by a ? Block containing a Fire Flower inside. Additionally, Goombas start falling down from a long row of blocks above.

Afterward, a block down below contains ten Coins that Mario can retrieve by Jumping repeatedly (at the right time) underneath the brick. Then there is the notable ? Block triangle formation, which contains no regular blocks. The top block contains a Fire Flower (or a Super Mushroom if Mario is regular instead of Super Mario). Upcoming are some more Brick and ? Blocks, follwed by a pyramid-like set of unbreakable blocks with a gap in the middle. After that is another set of unbreakable blocks, this time with a gap in the middle that Mario can fall into and get killed. Just following is another pipe that is unenterable, accompanied by two Goombas and a set of ? Blocks with coins inside.

Lastly, Mario reaches the Ending Staircase for the level, and the Flagpole afterward.
