The player has to enter the gap and keep moving to an enclosure of bricks near a yellow Warp Pipe that must be shell-dashed into. In the room with the second Star Coin and shifting blocks, the player can find a gap that never closes on the right side of the room. In World 1- Tower, Shell Mario is required in order to reach the secret exit. This leads to a Toad House and a shortcut to World 1.

Exiting through this pipe brings Mario to the red-flag exit. This leads to a small area with a Warp Pipe and the third Star Coin. In World 1-2, on the second tilting platform, Mario must jump onto the terrain above the bricks and coins. Hit it and wall-kick up the newly-revealed gap to get to the coin. Make him move and (you've guessed it) hit the ?-Switch behind him. Enter the door. There is yet another ?-Switch in this room. This time when the wall falls, however, enter the door immediately above you. From here, go right, hitting the ?-Switch you see there. Continue right and you'll see a Big Boo. Go through the same door you entered last time and hit the left ?-Switch yet again.

Go through the door and you're back where you started. The second Star Coin is on your right, at the bottom.

Climb up into the secret attic and enter the door. Hit the ?-Switch in there, and ride the block all the way down. Jump down and go through the door on the right. From here, make your way all the way to the right and enter the top door. In the new area, strike the ?-Switch and go all the way back to the left. Make the Boo move and hit the ?-Switch it was guarding. Hit it and make your way up to find the first Star Coin. Hit the three blocks there and you will find another ?-Switch. When you see some doors, head right, going through the yellow gates. From the start, head down using the ?-Switches.
