If you entered the code correctly, the message “Welcome to Secret Challenge Mode” will appear.

To indicate if a level has a secret challenge version, the new right arrow icon in the top right corner of the map screen will light up.
Secret Exit in World 7-4
To locate the secret exit in world 7-4, you will need a mini mushroom (stored, if possible). Move past the mid-level point and up to the left side of the screen (top). It will eventually come to a “?” flying. block. Use the mini mushroom to make Mario smaller and jump on the block to stop him. Then use the block to jump into the small opening in the brick wall. Do a “C” jump (backward C) and jump up and to the left to land on top of the wall. Go through and you’ll see a small pipe that only mini-Mario can fit into. Take this pipe to get to the secret red flag exit.
Secret Exit in World 7-5
Just before you get to the giant Bullet Bill, you’ll see a pipe covered in blocks. Use the Bob-ombs to pop the blocks then access the pipe to reach the secret red flag exit.
Go from World 5 to World 8
Enter the Ghost House of World 5 and get a mushroom from the blocks. Then, go up the stairs until you reach a place with three brick blocks on the left side of the screen. Get on top of them and jump to reveal three invisible blocks. Next, jump the wall on the left side to get on top of them. Stand on the raised block in the middle and crouch down, then jump to reveal a block with a vine on it. Climb up the vine and a Boxing Ghost will appear. Jump off the vine to avoid being damaged. Kill him and go back upstairs, and enter the door. Kill the two Walking Pumpkins and stand in the middle. The platform will wobble and as long as it stays in the center you should be fine. When you reach the top, go outside and jump over the flagpole. A path to the Warp Cannon will open up on the world map. Go inside and use the Cannon to get to World 8.
