New Super Mario Bros. 2: 4-A

To access this level, use five Star Coins in front of the 1-up House. This level features springy pink mushrooms. Making matters more difficult is the fact that the enemies (namely Goombas) also bounce off the mushrooms. So will the coins. Go right, then break the brick blocks to go down and left for the first Star Coin. Just move; jumping will bounce you over the platform. Keep going right, and you'll see some Red Coins. Next, you'll see a blue pipe making infinite Goombas and a green pipe next to it. It's a cannon. The item block on the left will fly away and has a 1-up. The right brick block can become a Gold Block. You'll drop down on the midpoint. Go right and you'll find the second Star Coin high between two blue pipes over a pink mushroom. You can't reach it on your own, so wait for the Goombas to start bouncing on the mushroom and bounce off one to get it. Coins will soon appear from below. Past the red pipe is an item block level with the platform. Pound it to make a Mini Mushroom appear and head to the right. Follow it past some blue pipes and get it, then go under the pipes for the third Star Coin. Go right and coins will appear from below all of the pink mushrooms. Next is the flag.

New Super Mario Bros. 2: 4- Ghost House

The item blocks won't move away from you, but they will float up and down. Go up all the stairs; the first door is fake. Step down to the floor and the walls will close in. They are being controlled by Boos and can change direction at any time. As the walls move right, you'll come across parts of the floor that rise. Stand on the far right part of the floor to make it rise to the ceiling. The walls will move to the left, revealing the first Star Coin. The floor will drop away once you get it. The walls will move right again. Wall jump up the left moving wall once past the rising platform that takes you to the first Star Coin to  reach a door overhead. It will take you a giant Boo and the Red Goal, which leads to 4-B. If you don't go for the Red Goal, you'll see a Red Coin Ring. The Red Coins will appear sequentially with other coins. The walls will be close enough for you to wall jump, so do so continuously after you pass the last Red Coin for the second Star Coin, which is near the ceiling. Drop down and you'll see a P-Switch. It produces Silver Coins. Quickly go up the next area. When you reach the spring, go left immediately for the third Star Coin. The left wall will block it off. Spring up to the next level, as the walls will soon close in on you. Wall jump up the left side to reach a door. It leads to a room filled with coins. The walls will soon close in, so jump up to the door. You'll drop down near the flag, with a spring. This leads to 4-2.

New Super Mario Bros. 2: 4-1

World 4 is a winter world, so some platforms may be icy. This level is filled with snow, Micro Goombas, and rocks. The rocks are damaging, so go over them. Where there is a rope overhead, the first Star Coin is below with four rocks. Either be quick, or wait until you get a certain item to destroy the rocks. To the right, a rock will drop down and roll to the right. Get on the platforms above and quickly go to the right. You'll see two brick blocks in the rock's path. Take a Koopa shell or use a Raccoon Tail to hit the block to the right. It has a Gold Flower, which can destroy the rocks. Go back left. On the middle platform, there is an invisible block. Hit it and jump on it to reach a higher platform that you couldn't see before. There's a P-Switch that makes Silver Coins over this platform. Hop on the platforms to the right to reach the second Star Coin. Carefully drop down to the midpoint. Rocks will be rolling down nearby, so be careful. To avoid some of them, one of which is giant, go through the blue pipe. It will take you to an icy room with on rock and a random coin block. Go through the top pipe to the left. Wait until the rocks go by and hop up the mountain. At the top, get a running start and jump to the left for coins and the third Star Coin. There's a Gold Ring at the top of the mountain, so activate it and get some coins. The brick block on the mountain has a 1-up. Beware that if you send the Koopa shell down the mountain, it will rebound. There's also a rock at the base of the mountain. Just past it is the flag.

This level has lots of saws, so stay out of the water and time your jumps. Go up into the alcove with coins to avoid a saw. Jump up and time your jump left to get the first Star Coin. The door at the top will take you to the midpoint. A giant saw is nearby. The minipipe overhead will take you to a Starman, so you can destroy the saws. Otherwise, drop down into the alcoves. The second Star Coin is on a platform with a Dry Bones in the middle of two saws' paths. This will lead into a maze of saws, so be careful. Once you're out of the maze, the boss door is nearby. Before you go through, hit the invisible item block on the right wall and go over to find coins, the third Star Coin, and a powerup. Through the boss door, we enter a room with four pipes. Wendy appears and the room floods with water while she hops around. Cheep-Cheep appear out of the top pipe. The water will drain and Wendy whistles, summoning Cheep-Cheep to jump up from below. When the water drains, you can hit her. The room will flood after a while, so see if you can get in a couple hits. Once defeated, the key will appear. Morton Koopa Jr. will take Peach to the Fort of World 4.

New Super Mario Bros. 2: 3-B

This level features the Mini Mushroom. Get one from the item block, swim through the water, and choose either the red pipe above or the yellow pipe below. The red pipe leads to a faster area than the yellow pipe. Both are automatic sidescrollers. Get the Gold Block and run on the water. The level will start to move. The first Star Coin is over a Parakoopa. Bounce off another Parakoopa to reach the platform below a green pipe. Go up the pipe and the level will stop automatically scrolling. There are Bill Blasters and coins high in the sky of this Coin Heaven. As Mini Mario, you can bounce off the Bullet Bills without stomping on them. Just bounce on them and let them take you through the coins to the second Star Coin at the end. You'll drop down to the midpoint at the end of the area. You can pick up another Mini Mushroom. Go through the pipe. Regardless of which pipe you took at the beginning, it will lead here, which scrolls slowly. There are Red Coins here, as well as brick blocks to make navigating tricky. The third Star Coin is to the right of one set of brick blocks, so get it quickly and jump over the next set. You'll soon make it to the pipe to the flag. This opens a path around the Ghost House to the castle.

Take the blue pipe underwater. There are Bloopers in the pipes waiting for you to pass by. Beware of the large rolling rock coming in from the upper right. Let it break the stones guarding the first Star Coin near the Blooper Nanny. Go down the yellow pipe near the Silver Coins and swim after the second Star Coin. Dodge a Blooper in a pipe and take the pipe to the left for the midpoint. There's another P-Switch which makes Silver Coins which lead to a blue pipe. The switch will also stop the current. The blue pipe leads to a P-Switch with more Silver Coins. Let the giant stones give you access to the third Star Coin. Take the pipe at the end to the flag.

New Super Mario Bros. 2: 3- Ghost House

This Ghost House is pretty interesting. Hop on the platform and it will be carried by ghosts. Don't worry; they won't hurt you. The platform will dump you off at a door. Go through it and hop on the next platform. Near the top, the first Star Coin is behind a Boo. The platform will disappear and you'll land on a platform below. Transfer again and take the top door. There's a Red Coin Ring. The platform will split up so you can get all the Red Coins. Behind the Boo is a random coin block. Go through the door. There are three platforms at the bottom of the stairs. The middle one will take you to the alcove with the second Star Coin. Take the platform on the right to reach the far right door. It will take you to the third Star Coin. Ride the platform to get it. Take the door on the left. It will return you to the room you were just in. Take the platform on the right again and take it to the second door on the right. The entire floor is a platform, rising up. Stay to the right, even though the platforms will shuffle. When they do, jump to the right for an alcove. Use your Raccoon Tail to break the brick blocks to reach a door. It will take you to Red Goal to the castle. If you can't reach the door, continue up to another door to the regular goal to 3-5.
