World 8 (New Super Mario Bros.)
World 8 is the final world of New Super Mario Bros. Mario and Luigi travel to this world in New Super Mario Bros. after defeating Monty Tank or Lakithunder, or using the World 8 cannon in World 5. This world is divided into two parts: a "dark forest" area, and a "lava" area; both having their separate Towers and Castles. The two bosses of this world are Dry Bowser; and a resurrected Bowser fighing along with Bowser Jr..
Unlike all the other worlds, this world does not feature secret exits or unlockable courses.
World 8-1
The first level in World 8 takes place on a barren wasteland, filled with Crowbers, Bullet Bills, Banzai Bills, Boos, and Splunkins. The first Star Coin is accessed by putting a spring on top of two blocks quite near the start. Mario will bounce up to the coin and drop down near the blocks. The next Star Coin is after the midway point, near a Boo. Mario has to jump on top of on top a Bullet Bill to reach the coin. The final coin is very close to the second, and directly underneath the path of a Banzai Bill. Mario must wait for the Banzai Bill to go over him, then jump down and get the coin.

World 8-2
The next level is an underground level, with ? Switches that cause water to rise inside and give Mario access to pipes. There is also a pipe Mario can enter if Mario is in his mini form. After one area, Mario goes to an area with many sinking barrels and Skeeters in between them. After getting past the barrel area, Mario can either go down the mini pipe or a normal one. The normal pipe leads to an area filled with Brick Blocks, which he can ground pound to get the first coin. The mini-pipe leads to an area with eight Micro Goombas and a Question Block containing a Star. After two more watery areas with Skeeters and ? Switches, Mario will reach the goal.

Bowser's Castle
This stage is the final level of New Super Mario Bros., being Bowser's Castle. Once the Mario Bros. are inside, they will encounter a massive amount of traps, including Rocket Engines and Thwomps. This level is the longest in the game, and some parts of it require pressing one of the many ? Switches to be found. These switches will flip the gravity of the castle upside down, and any enemy along with it. This action is required for getting to certain doors. Because this is the biggest stage, players are given 800 seconds to complete the level.
The first room of the castle involves crossing lava on solid platforms that are close by to each other, in which Mario or Luigi can run across, players have to avoid Podoboos while running across the platforms, after crossing the platforms and avoiding all the Podoboos, there is a door which will lead to the next room. In the second room there is three Brick Blocks and a door that is on the ceiling, the right one contains a Fire Flower and the middle one contains a ? Switch, jump on the ? Switch to rotate the room around to be upside-down and then enter the door. In the third room, there is 3 Brick Blocks at the entrance and Rocket Engines, avoid the Rocket Engines and the Dry Bones in the middle part, then avoid more Rocket Engines on the way across to the right and then enter the door. The fourth room at the entrance has a Super Thwomp and a narrow passage, the player must run passed the Super Thwomp when it starts to rise and then hit the third Brick Block next to the Super Thwomp to reveal a ? Switch and then jump on it to turn the room upside-down and the Super Thwomp will remain in the same part of the screen while the screen is rotating, then avoid the Super Thwomp again and enter the next room. The fifth room contains Rocket Engines and Dry Bones, avoid them while moving left and keep moving left and jump over the long gap containing spikes and hit the lone Brick Block to reveal a red ? Switch, while avoiding the Rocket Engine press the Red ? Switch to make a platform appear, and then move back to the middle part of the room then jump onto the ledge above while avoiding the Rocket Engines and then enter the door. In this room, there are Thwomps, avoid them while moving right, then move left while avoiding the Thwomp and collect the first Star Coin, then avoid the Thwomp again while moving right and avoid the Dry Bones and start moving right on the ledge below halfway and hit the Brick Block on the right which will reveal a ? Switch, press it and the room will turn upside-down with the Thwomps staying on the same part of the screen while rotating, to the right there is a Thwomp and a Dry Bones to avoid before entering the door which will go back to the previous room. Back in this room, there will be a platform that has appeared after pressing the Red ? Switch from earlier, there is a door on the right which will take Mario (or Luigi) straight to the sixth room of the castle, but instead jump onto the platform and enter the door on the left. In this room, move to the right below the stairs to find the second Star Coin, climb up the stairs and enter the door. In the seventh room, climb up the stairs and enter the door. This will take you to a long looping room (about half of the castle). When you come to three platforms, jump on them in this order. (Bottom, Top, Middle. Then pound the bricks and jump and wall jump. This will give you the third star coin and the last of the game.
After crossing the checkpoint flag, the second part of the castle is a long looping room, similar to the looping castles of 4-4 and 7-4 from Super Mario Bros. while players are avoiding a Podoboo and a Firebar, which can be passed by walking on the right platforms; a buzzer noise alerts players if they pass along the wrong platform. After that, collect the 3rd Star Coin which is trapped by some unbreakable blocks, a passable platform and two Brick Blocks, destroy the Brick Blocks with a Ground Pound and then get up the stairs and go back down while sliding to collect the third and final Star Coin. Once that is done, enter the boss door.
Once inside the room, the player will encounter Bowser Jr. on a long bridge over a deep pit. He will toss his father's bones into the cauldron, thus reviving him, much to Princess Peach's horror.
The duo will then fight Mario/Luigi together, with Bowser Jr. using his usual shell-tossing tactic, and his father breathing flames behind him. After the player defeats Bowser Jr., his father will increase his attacks greatly. When Bowser breathes blue fire it can turn Mario/Luigi into Mini Mario or Mini Luigi. Mario/Luigi must then run under one of Bowser's giant jumps and hit the Skull Switch at the end of the bridge, ending the fight and winning the game. Another way to win is if the player has a Mega Mushroom as a stored item; upon using it, the player can jump on Bowser, then make Bowser Jr. fall after hitting the Skull Switch. The player can also hit the Skull Switch without defeating Bowser Jr., causing both him and Bowser to plummet. The player can also defeat Bowser before his son using a Fire Flower, but it will not change how Bowser Jr. attacks. The platform that Princess Peach is standing on will disappear, she floats down saying, "Thank you!" and rewarding Mario/Luigi with a soft kiss.
