World 1 (New Super Mario Bros.)

World 1 is a place that is found in the game, New Super Mario Bros.. This place was actually around Princess Peach's Castle. The ground had grass and flowers growing on it, since it is a grassland-themed world like World 1 in some other games. This is where Mario and Luigi's adventure started as they go around the levels. This world takes place in the Mushroom Kingdom.

Bowser Jr. was fought here for the first time, and Bowser was the first boss in the game, not counting Bowser Jr. who's a mini-boss. After defeating Bowser, the brothers would go to World 2.

World 1-1


The first level in New Super Mario Bros., is a meadow with flowers, bushes, and mushrooms scattering the land. Peach's Castle is visible in the background for the first portion of the level. The level introduces the Goombas and Koopa Troopas.

The first ? Blocks that Mario encounters have 2 Coins in them, and one that has a power-up. Going on into the level, Brick Blocks appear. The top one contains 14 coins and a Super Mushroom. Underneath that one contains 1 coin, while the rest are simple Brick Blocks. Mario then encounters a Goomba, who he stomps on, being next to a Pipe. The Pipe is not able to go down to, however. Another Goomba appears to stop Mario, but he just easily stomps on it, and jumps over an abyss while collecting coins. A block is struck about 1/3 through the level, and a Mega Mushroom is encountered for the first time, making Mario become the huge Mega Mario, destroying everything in its path. However, if the player chooses not to get the Mega Mushroom, they should keep advancing. The player will now see their first Star Coin. There are some Koopa-Troopas and a Goomba in this area. There is also a hidden vine that leads to the sky with Red Coins. It is located inside a Brick Block where the Red Koopa Troopa is walking. The pipe that's currently visible to the player leads to an underground room with a Star Coin in it, and a power-up. The player will see 3 Brick Blocks with coins in them, but if the player jumps on top of the middle Brick Block, a Star will come out of it. Another ? Block will be here, this time containing a power-up. A set of Brick Blocks will be blocking the second Star Coin, the player has to ground pound it to break it and get the Star Coin. Another ? Block will be here, containing a single coin. A couple of Goomba's and Koopa-Troopa's will appear in this area, along with Brick Blocks and Coins. The player will now see the flag and finish the level. They will now gain access to World 1-2. There are a few vines leading to platforms and other things and an Invincibility Star is found above a Brick Block before the end of the level.

 * Star Coin 1 - Found atop a ledge of blocks. Mario or Luigi will either have to jump off the blocks or be Mega to get this coin.
 * Star Coin 2 - By entering the Warp Pipe after the first star coin, Mario or Luigi will need to avoid Goombas and pits to reach the end where the second Star Coin rests.
 * Star Coin 3 - Mario and Luigi will need to ground pound some Brick Blocks to obtain this Star Coin.

 * Goomba
 * Green Koopa
 * Red Koopa

World 1-2


Pursuing the chase after Bowser Jr., Mario finds himself in a strange cave. Adventuring on, Mario finds that many Goombas and Koopa Troopas inhabit this cave. He then sees some ? blocks. Hitting it produces Coins. Mario collects them, and moves on to a strange sight - a Star Coin. He jumps onto the ledge, and collects it. He could also Ground Pound on some brick blocks to collect a bunch of coins. He then moves on, encountering more Goombas. Going forward, Mario finds a block of rock that he can't get through - yet he prevails by smashing the brick blocks above it, and getting through. An abyss is then met, Mario easily jumps over it, but then meets a Star Coin surrounded by some brick blocks. Trying to find out how to get in, Mario jumps to the top and Ground Pounds it - the blocks are destroyed, and Mario gets the Star Coin. A Piranha Plant is then met. Mario jumps over it, and goes down the pipe it was guarding. Mario, finding a passageway, collects the Coins, then hits the Koopa Troopa to break some brick blocks, creating a passageway. Mario crawls under the passageway - he then comes across, and finds some Goombas. Running, he then sees a ? block. A Mega Mushroom pops out. Mario collects it, and destroys all the Goombas and brick blocks. He then goes up a pipe nearby. Mario is then in the main cave again, and jumps carefully over some pipes sticking out of an abyss. He then makes it onto the ground, and runs forward. He then meets a tilting log. He runs over it, and continues through the cave. A pipe then greets him, as he appears out of the pipe, and into the sunshine again, and also near the Flagpole. He then finishes the level. There is an Invincibility Star above the first Brick Block after the first Piranha Plant.

Secret Exit
As Mario reaches the second log, he jumps to the upper solid ground and dashes quickly until he reaches the last Star Coin. He than grabs it and exits from the green pipe thus ending the level.

World 1-3


The level starts off with a few tilting mushrooms where Mario can find a block with a Super Mushroom or a Fire Flower. In the next area, there will be a few spin-jump pads that will make the player spin jump very high. If the player spin jumps onto a platform higher in the area, this one leads the player to a bouncy mushroom that is below the first Star Coin in the level. The player will also find a path of coins in the air. If the player follows the path correctly, the player will easily get another Star Coin and will be halfway through the level. Now the player has to go onto several tilting mushrooms that are moving up and down. The player can get the level's last Star Coin here. Next the player will find a Red Ring which will make Red Coins appear. There are also more mushroom platforms. Then there are two more tilting mushrooms and the player will reach the level's Flagpole.

World 1-Tower


The player starts out on a rising and lowering platform if which the player stays on it for long enough it will go down and this will reveal four coins. Mario then progresses encountering the first Dry Bones of the tower and the game. The player then keeps on going up finding two ? Blocks, one containing a coin and thge other either a Super Mushroom or a Fire Flower depending on what form Mario is. The player continues to progress up the tower but some platforms appear pushing out from the walls. If the player is in between the platforms the player will lose a life. On the last platform he encounters another Dry Bones. Still going up, the player has to jump up a couple of platforms, then the player has to turn right encountering platforms trying to push down on Mario. The player continues to progress up finding finding another group of platforms. The player finally reaches to the last one which Mario is on top of the platforms, here the player also encounters another Dry Bones. The player will also find a Star Coin and two blocks, one is a brick block block and the other a ? block. The normal block contains coins while in the other block there is a Mushroom or a Fire Flower. The player progresses up finding platforms pushing out of the wall which if the player can pass them fast enough they will appear as a stair case. The player has to go up it finding the player in between an unusable door and a Warp Pipe. The player can go into the warp pipe which will shoot the player, making Mario reach the check point.

The player either go up towards the Door or go down to get more coins. If the player decides to go up, the player finds a warp pipe cannon that will blast Mario past a series of moving platforms. If the player times it right Mario will get to the Boss Door easily, if not the player will lose a life by being crushed between the platforms. Here there are two Super Dry Bones trapped in two enclosed platforms. The player also finds a ? Block which contains either a Mushroom or Fire Flower. The player has to enter the door in order to progress. The player will now find Bowser Jr., who challenges Mario to a battle. Bowser Jr. will run around the room, trying to run into Mario.

After his first defeat, Bowser Jr. will then take Peach away with him to the castle of World 1.

Secret Exit
In order to reach the secret exit, Mario will have to be Shell Mario. 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. The player has to enter the gap and jump upwards to find a 1-Up Mushroom, then the player has to jump onto five more blocks. The player has to start the Shell Dash. After destroying all the blocks, the player has to enter the pipe. Next the player will fall to the right after exiting. The player has to jump onto a block to grab another 1-Up while unlocking the Warp Cannon which will shoot the player all the way to World 5.

Star Coins

 * Star Coin 1 - Guarded by a Dry Bones after a few sets of blocks.
 * Star Coin 2 - Taking the path to the upper right will lead the bros. to this coin.
 * Star Coin 3 - In the upper left, there is a yellow door. Taking it will not only lead to a Star Coin, but also the secret exit.

Enemies

 * Dry Bones
 * Super Dry Bones
 * Bowser Jr. (mini-boss)

World 1-4
This level is a grassy meadow, much like World 1-1. The first ? Block (which is on the ground, and not floating, unlike most ? Blocks) contains a Super Mushroom or Fire Flower. A ? Block containing a Mini Mushroom is later found in the level. The Mini-Mushroom can be used to travel into a small pipe nearby that lead to the first Star Coin. A wall made up of Brick Blocks and cement blocks are blocking a Pipe. The wall is shaped in such a way that it's possible to throw a Koopa Shell on it, which will break all of the Blocks and will eventually allow the player to enter it. Alternatively, the player could use a Mega Mushroom to break the block Wall, although the Pipe could end up being accidentally broken, but it's also easy to just groung pound them. The pipe leads to a cave that contains a Star Coin that is reached by using a P-Switch that turn every Brick Block into a coin and vice-versa. The third Star Coin is found in a small gap just before the level's Flagpole that is only accessible by Mini Mario, Shell Mario, or Mario without a Super Mushroom.

Infinite 1-Up Trick
This level possesses one of the few places in the game where it is possible to generate an infinite number of Extra Lives. The Koopa Troopa just before the Block Wall, marching on top of four blocks, must be used. Jump on it and grab the shell. Carry the shell over the block wall and continue right, carefully avoiding Goombas, until passing over a short green pipe just over the lip of a small cliff. Immediately past the green pipe is a small hill; walk to the top of the hill, at which point the player can just see a horizontal yellow pipe with Goombas coming out of it on the right side of the the screen. Release the Koopa Shell while standing at the top of this hill and allow it to bounce back and forth, jumping each time it goes by so Mario won't get hit. Goombas will continue to emerge from the yellow pipe on the right, and the number of points each time a Goomba is hit will climb until every hit results in an Extra Life. It is possible to collect up to 99 Extra Lives, the maximum allowed in the game. (Note: It does not appear to be possible to do this trick by spinning between the pipes using Shell Mario, as Shell Mario only scores a fixed 200 points per Goomba hit; the points per hit will never grow past 8000 to the Extra Life per hit.)

Star Coins

 * Star Coin 1 - Use the Mini-Mushroom in the ? Block to enter the Mini-Pipe to the left. The coin should be in plain sight.
 * Star Coin 2 - Near a mass of blocks is a pipe blocked by a Brick Block. Break it and find the hidden P-switch to turn the coins into blovcks to make steps for the Star Coin.
 * Star Coin 3 - The third Star Coin is found in a small gap just before the level's Flagpole that is only accessible by Mini Mario, Shell Mario, Mario without a Super Mushroom, or by sliding down the nearby slope.

Enemies

 * Goomba
 * Green Koopa
 * Green Koopa Paratroopa
 * Red Koopa

World 1-5
The level starts out on a basic red mushroom, which leads into many pink-colored bouncy mushrooms. Towards the middle of the row of bouncy mushroom is a Star Coin, surrounded by four normal coins. At the end of the bouncy mushroom row, are two dropping platforms (if stood on for awhile, they both fall down), and right after this, is another Star Coin. Afterwards, there are four dropping platforms and a pipe (which can be entered) above the platforms. Inside the pipe is a moving red mushroom, which will move across rows of regular coins (a Star Coin is located in a mushroom formation in the middle of this row). Afterwards, the player then drops downwards (not far from the location of the pipe). Then come another row of bouncy mushrooms and a Red Coin Ring, and, if the player goes into the ring, he or she must grab the eight red coins while avoiding a Goomba and a Koopa-Troopa. Afterwards, there is another long row of the bouncy mushrooms, with a row of brick blocks with coins on them. At the end of the row is the flagpole, resulting in the level being finished.

Star Coins

 * Star Coin 1 - In plain sight. Use the bouncy mushrooms to get it.
 * Star Coin 2 - Use the dropping platforms to reach the Star Coin on top of a mushroom.
 * Star Coin 3 - By entering the aformentioned pipe, ride the mushroom all the way to where the Star Coin is.

World 1-A
First, the player has to go down the Warp Pipe, and the player will see an underwater world. Also, a ? Block with a power up can be found. At this point the screen will scroll automatically: that means Mario will be crushed by solid obstacles if he was hit with that at the most left of the screen. Sushis, will appear at both the top and bottom of the screen, two each time. If it is hit by one of Fire Mario's fireballs it will be defeated quickly.

The player can find a P-Switch while swimming along this level. If the player hits it, it will produce Silver Coins between bouncy obstacles. Then, by going high as possible, the player can grab the first Star Coin. From there Mario will go right, entering the pipe leading upwards, appearing near the second Star Coin.

When entering the underwater world again, take up the random Power-up Block while avoiding the Cheep-Cheeps. The player has to dodge the Sushis coming from the left and the can go through a Red Coin Ring to get red coins. The Sushis will now switch back to attacking from the right, but what makes difficult is the current of bubbles from pipes; there's also a silver coin challenge for the player to try.

The player has to swim right as soon as the Star Coin appears above, grabbing the Star Coin, followed by either ducking to avoid the incoming Sushi or swim back out quickly. There's a pipe that leads to the next Star Coin. Going back out the pipe, the player has to swim past the last few Sushis and head up the pipe, going forward to jump onto the flagpole to end the level.

Star Coins

 * Star Coin 1 - On the top of the level it will be guarded by invisible blocks on the bottom, so approach the coin form the left or right side.
 * Star Coin 2 - Right after the first Star Coin is a pipe. Take it and the bro will be transported above ground where the second coin resides.
 * Star Coin 3 - Mario or Luigi will have to maneuver themselves around a stone structure to the right opening to obtain the final coin.

World 1-Castle
This level is the castle of the first world. It is the location of the game's first major boss fight.

The majority of the level consists of walking on tightropes over lava. Along the way, Mario encounters Podoboos and Dry Bones. There are also several platforms that move up and down, some of which sink into the lava. Eventually, Mario comes to safe ground. However, it is below a ceiling of spikes that slowly lower themselves down to the ground. Mario must jump to in-between gaps before he is crushed (one that has a Star Coin that Mario can wall jump to, and then get through a second lava-filled area (another Star Coin is on a moving platform that sinks into lava). Before making it to the boss door, Mario can jump on the last tightrope to find a hidden pipe with a Star Coin in another room.

Bowser is the boss of the first world. As Bowser Jr. original did not find a proper boss to inhabit this castle, he got his dad to do it. The fight is very similar to the ones from Super Mario Bros.; the fight takes place on a small bridge above a pit of lava, with a Skull Switch (replacing the former ax) at one end. Mario must get either under or over the Koopa King and hit the switch, which will collapse the bridge. After the Koopa King's defeat, he is reduced to a skeleton (Dry Bowser), and is not seen again until World 8.

Star Coins

 * Star Coin 1 - The first Star Coin is placed near the ceiling. Mario or Luigi will need to Wall Jump off the spiked ceiling crushers to get it.
 * Star Coin 2 - Near the end of the level are two platforms. One of the platforms has the coin, but the bros. will need to wait for the second platform to come up to obtain the coin.
 * Star Coin 3 - Right after the second Star Coin is a long stretch of rope. Near the middle of the rope is a Warp Pipe located on the ceiling. Using the rope, jump to the ceiling and go in the warp pipe to obtain the last Star Coin.
