Super Mario Bros. Guides

World 1

1-1
Hidden 1-Up
After the forth green pipe wall slowly forward until about 1/4 of the pipe is out of the screen. Jump up and you should hit the right corner of a 1-Up block. Quickly jump again to get the mushroom.
Coin Room
The forth pipe from the start leads to a coin room. If you do it right, you can get the 1-Up and the coin room.

1-2
1-Up
The brick block above the last block on the floating platform with six coins holds a 1-Up Mushroom. With Super or Firey Mario quickly break the block next to it to make it fall. As normal Mario you can follow it along the top until you come to the moving platforms.
Coin Room
The first pipe after the platform with the six coins leads to a coin room.
Warp Zone
Use the second set of moving platforms to jump atop the brick cieling and run to the right until you come to the Warp Zone. You can choose between Worlds 2, 3, and 4.

1-3
Nothing
Beat this level extra fast just to spit in its worthless face.

1-4
Six Hidden Coins
You can find six coins in hidden blocks in the first pit area of the castle.

Bowser
Bowser can be defeated using five fireball, or by running past him and grabing the axe. Do not attempt to jump on him!

World 2

Hidden 1-Up
If you warped to World 2, there is a hidden 1-Up next to the line of blocks above the Koopas near the start. Below is a hidden coin block you can use to reach it.
Vine
When you come to a place with two groups of coin blocks next to each other with a small break in between and bricks above, hit the last brick above the opening to sprout a vine that leads to coins in the sky.

2-2

Nothing
Nothing to see here, move along (quickly! those fly fish are dangerous!).

First Warp Zone
This level has two Warp Zones. After the first set of moving platforms move under the third brick and jump to reveal a hidden block. Do the same thing to the block to your left, but do not do it to the third one if you are Super or Firey Mario. The first of the three bricks sprouts a vine which leads to an area with coins. Continue to the right to reach a Warp Zone for worlds 6, 7, and 8.
Second Warp Zone
Use the tall pipe near the end to get above the cieling and run over the exit pipe the same way as in 1-2.
Coin Room
The third pipe after the vine leads to a coin room.

4-3
Nothing
Are you seeing the trend here? Third levels suck.

Maze
Once you figure out the maze this is the easiest castle. The correct route is to go up until you reach the stairs, then go all the way down until you reach Bowser.

1-Up
Straight up frim the spring board is a 1-Up.
Coin Room
The pipe after the long pit leads to a coin room.
8-3
Hammer Bros.
This level is infested with Hammer Bros. The blocks each of the two sets of Hammer Bros. each hide a Mushroom / Fire Flower. Try to become Firey Mario before you get past the second set. If you can’t, your best bet is to run in close to the Hammer Bro. where it can’t hit you, and wait to run under when it jumps.
8-4
Maze
Go down the first pipe after the first lava pit. Continue until you come to a pipe in the air. To the left is an invisible coin block to help you reach the pipe. Go down the next pipe after lava. When you come out of the water continue past the Hammer Bro. and on to Bowser. This time, our Princess is not in another castle…
