World 8-3 (Super Mario Bros.)

World 8-3 is the third level of World 8 in Super Mario Bros.

Layout
The player begins in front of a Bill Blaster, which is followed by a Koopa Paratroopa, another Bill Blaster, and a pipe with a Piranha Plant. After the pipe is a duo of Hammer Bros. that jump between two rows of Brick Blocks, and in the second to the right block of the top row is a power-up. After a small staircase, a Bill Blaster, a Koopa Paratroopa, and some stone pillars is another Hammer Bro. 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 Bros., and at the end of the second castle decal is a hidden Coin Block (which is in plain sight in the Super Mario All-Stars version of the level). After some small stone platforms is the Goal Pole.
