New Super Mario Bros.

New Super Mario Bros. is a side-scrolling platformer game exclusive to the Nintendo DS, starring Mario and Luigi. The game features a solo story mode with Mario or Luigi, a two-player wireless game Mario vs. Luigi, as well as a mini-game mode for up to four players. And players can also access Luigi as a story mode (1 player) character if they press L and R and select a file at the same time. The multiplayer games support both single-card and multi-card play. Most of the mini-games are mostly the same as those featured in Super Mario 64 DS, with the difference that they do not need to be unlocked here. The game received a follow-up, which is New Super Mario Bros. Wii.

Story
Mario (or Luigi depending on who the player is playing as) and Princess Peach are walking together around Peach's Castle, when a mysterious thundercloud appeared, and struck the castle with lightning. Mario/Luigi went to investigate, and while he is there, Bowser Jr. sneaks behind a bush and kidnaps Peach. Mario/Luigi follows, and Bowser Jr. drags her behind him through eight different worlds.

The end of the first world has Bowser as its boss, unusually. Even more surprising, after Mario presses a switch that destroys the floor and Bowser falls into the pit of lava, the king's flesh is burned off and he becomes a Dry Bones-like version of himself (known as Dry Bowser). Later, at World 8, Mario has to face this undead version of Bowser as the penultimate boss in the game. Dry Bowser falls into a pit, but Bowser Jr. somehow finds his father's bones, and he revives him by tossing his remains into a bubbling cauldron, which results in not only Bowser returning from the dead, but growing roughly three times his size.

At the end, Bowser and his son fight Mario together, but Mario defeats them, sending the two into yet another pit. After the ending sequence, Bowser Jr. is shown dragging his unconscious father across the castle floor. When he notices the player watching him, he shouts something and then continues on with his task.

Controls
New Super Mario Bros. is very much like Super Mario Bros. in terms of gameplay, but new features have been added. One of two control options can be selected in the Options menu: Jumping with A/B and Dashing with Y/X, or Jumping with A/X and Dashing with Y/B. Mario is controlled with the D-Pad, and the Touch Screen is only required to activate the stored item, which is used in the same style as in Super Mario World. When Mario enters a pipe to a secret area, the top screen and the touch screen are switched, and gameplay continues on the touch screen as long as Mario is in that area. In that case, the stored item cannot be activated.

Moves and Items
The Wall Jump makes its first appearance in a 2D game since being introduced to 3D Mario games with Super Mario 64. In contrast to the 3D games, Mario has to slide down a wall for a considerable amount of time before being able to jump. This technique lets Mario or Luigi reach new areas by bouncing off the side of any wall or vertical object, and is useful for escaping from a fall down a hole. Mario has the ability to Ground Pound by pressing down when in the air, allowing him to smash blocks downward. There are different power-ups, like the Blue Koopa Shell that lets Mario travel like a kicked Koopa Troopa shell, the Mega Mushroom that makes the player grow about three to five times Mario's size (also seen in Super Mario 64 DS), and the Mini Mushroom which causes Mario to grow about half of Small Mario's size. However, some items remain unchanged, such as the Super Mushroom, the Invincibility Star, and the Fire Flower.

Levels
The game also features a world map, with different and secret paths (like Super Mario World). Alternate paths can be unlocked with Star Coins. There are three in each level, usually adding an extra challenge for the player apart from just reaching the goal. Some are in clear sight while others are hidden in Warp Pipes, up Beanstalks, or other inconspicuous places. On the world map, signs block paths that require five Star Coins to open. After a player defeats Bowser and Bowser Jr. in Bowser's Castle, a new, mysterious blue Toad House will appear just above World 1. It is a market, and for 20 Star Coins, the player can buy a wallpaper for the bottom screen. The fifth and final background is only available after all of the 40 Star Coin Gates have been opened. Mario or Luigi only has to go through six of the eight worlds &mdash; after World 2, the player gets to either of World 3 or World 4, and the world following both of those is World 5. After World 5, the player can get to either World 6 or 7 in the same fashion. Mario or Luigi must defeat the World 2 or World 5 bosses in Mini mode to instead reach World 4 and World 7, respectively.

Another secret is Challenge Mode. This means the player cannot scroll the screen to the left or downward. To unlock it, the player should go to the map screen (any world) and press START, L, R, L, R, X, X, Y, Y. It will also show an arrow pointing right on the world maps and levels touch screen. This means that the player cannot turn back in all the courses (including castles), which adds the feeling of the original game even more.

It is also possible to play as Luigi in single player mode by holding down L+R when selecting a file. There are no gameplay differences between the brothers. The character does not get locked in - players can choose a different character every time they load the game. After the final boss has been beaten, a star appears next to the Save Game function. When the player has completed all levels, there are two stars next to it. When the player collects/spends all the Star Coins in the game, there will be three stars on the save file.

Mario vs. Luigi
In this two-player mode, Mario and Luigi compete for a number of stars. Those stars will appear at random in the side-scrolling stages. The end of each of those stages is their beginning (basically, the stages are never-ending). When Mario or Luigi are hit by enemies, fall down or hit each other, they lose a star, which can then be again collected by any of the brothers. The first brother to reach the previously set amount of stars wins the game. When a brother has a certain amount of victories, he wins the match. The following stages can be played:
 * Grass Stage - A stage that is much like World 1-1 of the single-player game, a meadow near Peach's Castle. It uses also many elements of World 1-1 form the Classic Super Mario Bros. This stage is a relatively simple stage with only Goombas and not many other enemies to worry about.
 * Underground Stage - an underground stage much like World 1-2 of the single-player game, it has covered with many walls of blocks, and has several holes which may be fallen into. Mario/Luigi should be very careful if they get a Mega Mushroom in this stage, as they can easily crush through the bricks that most of the course is made of.
 * Ice Stage - a slippery stage located in World 5. Bullet Bills are hazards in this stage. There is also a Blue Koopa Troopas in this level; jumping on it will reduce it to being a Blue Shell which can be used.
 * Pipe Stage - a pipe world located in World 7, it contains many Warp Pipes and Piranha Plants.
 * Castle Stage - the most hazardous level, located in World 8. It contains Bob-ombs, and moving walls which can crush a brother to death, among other dangers.

References to Other Games

 * Super Mario Bros.- There are two unlockable skins for the bottom screen that resemble something of that game. One shows an 8-bit Mario from that game, close-up. The other one is a secret unlockable skin and it features Mario, Luigi and some Goombas all as they appear in this game, they are even in an area similar to the areas in this game. The overworld Multiplayer stage is based on World 1-1. Bowser and Dry Bowser are defeated the exact same way as in the SMB castles - by hitting the Ax/Skull Switch which makes the bridge he's standing on fall into the lava or a bottomless pit, respectively. The latter also applies to the final battle against Bowser and Bowser Jr. The color scheme of the Mega Mushroom in New Super Mario Bros. is similar that of the Super Mushroom in this game. If the player finishes a level with the last 2 numbers of the time limit the same, the player gets the level complete soundtrack from the original Super Mario Bros.. When the Player loses a life the same music appears from when this happens also happens in this game. It later happens in New Super Mario Bros. Wii.
 * Super Mario Bros. 3 - One of the hazards of the Castle multiplayer stage is the moving roof that will crush players upon contact. This seems to be based on the fact that there were moving roofs in some of the SMB3 fortresses/castles. Also, in Boss Battles, the Super Mario Bros. 3 boss music lintens. Also, the Bowser theme from here is heavily remixed into this game. The two games' worlds are relatively similar. Toad Houses make a return, as well as the various minigames from Super Mario Bros. 3.
 * Super Mario World- an item is stored on the touchscreen, and can be summoned at any time during each level. This derives directly from Super Mario World. Grinders don't appear in New Super Mario Bros., but spiked balls appear in the game, having the same function. Items can be held in a level, just like in the aforementioned game. Also, Small Mario can crouch.
 * Super Mario 64- There are several characters from this game reappearing here, such as Dorrie and Sushi. Many of the Mario Bros.' techniques, such as the Triple Jump, are also borrowed from this game. The theme used for the Invincible Mario Bros. is the same as the theme for Wing Mario and Vanish Mario.
 * Super Mario 64 DS- The characters reappearing from Super Mario 64 are as they appear in this game. Additionally, the effect of grabbing a Super Mushroom in Super Mario 64 DS is much similar to the effect of the Mega Mushroom in other Mario games. Many (if not all) of the minigames in New Super Mario Bros. are the same or very similar to those in this game.

References from Later Games

 * Mario Kart Wii - The Mega Mushroom appears as an item. Also, Dry Bowser is a playable character.
 * Super Smash Bros. Brawl - The Mega Mushroom appears as a sticker. Plus, the main theme is one of the many songs in this game.
 * Mario Super Sluggers - The Castle BGM is used for the Bowser Castle baseball stadium. It is remixed during the process.
 * New Super Mario Bros. Wii - A sequel to New Super Mario Bros..
 * Mario and Luigi: Bowser's Inside Story- The Blue Shell reappears. The Mega Mushroom also appears in one of Broque Monsieur's attack.

Trivia

 * Whenever music is played that has a vocal riff "wah" (or in the case of the underwater levels, a bell tree), some enemies and power-ups move to the beat. This includes the Overworld, Athletic, Underground, Desert themes. This also happens in New Super Mario Bros. Wii.
 * Examples would include: Goombas hop, Koopas turn to face the player, Spinies switch directions, and power-ups hop. Goombas can actually dodge a Koopa Shell with the hop. This is most likely an error.


 * If the player defeats the final boss after collecting the Star Coins in every world, none of the pictures shown in the end credits will say NEW.
 * If the player finishes a level with the last 2 numbers of the time limit the same, the player gets the level complete music from the original Super Mario Bros.. Fireworks also occur, appearing the amount the numbers specify (e.g. 2 blasts for x22, 7 blasts for x77, etc.).
 * During the ending, if the player taps the letters in the credits, they will make sounds from the game, with each letter of the alphabet making a different sound (except for D and E, which share a sound).
 * During Mario World in Dream Figure Skating in Mario & Sonic at the Olympic Winter Games, 3 Backgrounds from this game appear. They are World 1, Bowser's Castle and Peach's Castle. Also, in the Wii version of the game, the same Star-theme plays as from New Super Mario Bros.
 * It is interesting to note that when the Main Theme is uncompressed, it sounds like this . The compressed one sounds like this.
