'''World 8-3''' is the third level of [[World 8 (Super Mario Bros.)|World 8]] in ''[[Super Mario Bros.]]'' and the thirty-first level and penultimate overall in said game. This level is usually called the hardest level in ''Super Mario Bros.''  It is notably the only third level of a world in the game to not be of the athletic level type, meaning it is not based around jumping from high platforms over [[pit]]s. Instead, this is a mostly flat overworld level taking place within [[World 8-4 (Super Mario Bros.)|the final castle]]'s exterior walls.

==Layout==
The player begins in front of a [[Bill Blaster|Turtle Cannon]], which is followed by a [[Koopa Paratroopa]], another Turtle Cannon and a [[Warp Pipe|pipe]] with a [[Piranha Plant]]. After the pipe is a duo of [[Hammer Bro]]thers that jump between two rows of [[Brick Block]]s, and in the second to the right block of the top row is a power-up. After a small staircase, a Turtle Cannon, a Koopa Paratroopa, and some stone pillars is another Hammer Brother duo, and in the second to the left block of the top row of Brick Blocks is another power-up. Beyond a pipe is a row of Hammer Brothers, and at the end of the last castle wall is a hidden [[Coin Block]] (which is in plain sight in the ''[[Super Mario All-Stars]]'' version of the level). After some small [[Hard Block]] platforms is the [[Goal Pole|flagpole]].

===''Super Mario Bros. Deluxe'' challenges===
In ''[[Super Mario Bros. Deluxe]]'', the player can collect five [[Red Coin]]s, find a hidden [[Yoshi's Egg|Yoshi Egg]], and get a medal based on their score. The Yoshi Egg is found in a [[Hidden Block]] directly above the left of the castle decal after the second set of Hammer Brothers, and the score to beat is 28000. The Red Coin locations are:
*Directly above the fortress at the start of the level. A Hidden Block can be found to the left
*Above the top row of Brick Blocks with the first duo of Hammer Brothers
*On the small stone steps
*In a newly placed Coin Block in the center of the top row of Brick Blocks with the second duo of Hammer Brothers
*Above the floating blocks at the end of the level
