Super Mario Maker for Nintendo 3DS

Super Mario Maker for Nintendo 3DS is a Nintendo 3DS port of the 2015 Wii U title Super Mario Maker. Despite being a Nintendo 3DS game, it is only playable in 2D. It was initially released in December 2016, roughly 15 months after the Wii U version.

Changes and new features
The game includes almost everything from the original Wii U release, with the exception of the Costume Mario and Big Mario forms and searching for courses by code. It is also possible to play stages from the Wii U version, though not every stage is compatible with the 3DS version due to version differences, such as the removal of Mystery Mushrooms and Big Mushrooms from the 3DS version.

Exclusive to Super Mario Maker for Nintendo 3DS, the game includes 100 new courses designed by Nintendo pre-installed. The courses also include medal objectives, in which the player must fulfill certain criteria, such as collecting every coin in the level, to earn a medal. Players can also send unfinished courses to other players, by way of Local Play, and they can team up, or collaborate, on stages. Stages made in this way have a special icon marked next to it. The editing mode of the game also includes Yamamura's Lessons, an interactive tutorial guided by Mary O. and Yamamura.

Super Mario Challenge
The Super Mario Challenge (called Challenge Courses in the Coursebot) is a challenge mode containing 100 levels. It has Challenge Medals to collect that come in handy for accessing the 19th world.

Gameplay
The 100 levels are divided up into 19 worlds. However, Princess Peach is taken to World 18. The player needs to go through 88 of the 100 levels to rescue Peach. World 19 is unlocked in the Coursebot when she is rescued. The first level in World 19 is dependent on collecting 40 Challenge Medals. The actual mode has the player starts out with 10 lives, but they can increase it to 100 lives. If the player has a Game Over, the player has to restart from the beginning of the world they are on. Lives gain or lost in the Coursebot don't change the lives in the mode. After rescuing Peach, the player can redo the whole entire thing again if they want to with altered text for completing World 19.

The Super Mario Challenge mode also features a map that has 18 worlds. The number of levels start at four (Worlds 1-7, 10-12, 14-16), increases to six (Worlds 8 and 13), then increase to eight (Worlds 9, 17 and 18), and finally to twelve (hidden World 19) with the color of the world map background gradually changing as well (with the exception of World 19 which is exclusive to Coursebot).

Challenge Medals
The are two types of Challenge Medals that can be collect through the playthrough or Coursebot for each level. Nintendo mentioned some of these challenges in trailers before the game came out. The first medal is the Goomba Challenge Medal. It is available on the first time play. The second harder medal is the Bowser Challenge Medal. This one doesn't show up until either it is completed or the Goomba Challenge Medal has been earned. The Bowser Challenge medal can be either a more advanced form, a total opposite, or a non-related challenge of the Goomba Challenge Medal.

Assist Items
Assist Items are items that could appear when the player loses five lives. The player can choose not to accept the item, but they would be asked again if they lose five more lives. If the item is activated, the Challenge Medal would become unobtainable. Assist Items can't be activated past the checkpoint as it too removes the possibility of collecting Challenge Medals.

Ending
After the player rescues Peach, the credits roll while Mario walks. There are coins at the top-left corner possibly meaning lives added. When Mario enters the castle, the score of all 88 levels is totaled. After that, a "To be continued..." message appears due to the player needing to play the 19th world for some bonus stuff.

Glitches
NOTE: All names are conjectural unless otherwise specified.

Headless Bowser Jr.
NOTE: This glitch only works on the New Super Mario Bros. U game style.

For this glitch, the player must have a Bowser Jr. and a Koopa Clown Car, regardless of which type it is. When Bowser Jr. takes any form of damage or is far away from Mario, he hides into his shell and starts speeding towards Mario. If he falls into a Koopa Clown Car while inside his shell, his head will be jammed inside, giving somewhat of a headless appearance.

There is also another way to experience this glitch by using a Spiny Shell on Mario. When Bowser Jr. hides into his shell, the player should wait until he jumps back out to attack. When he is in mid-air, Mario needs to run under him so he takes damage. When he jumps from the damage, Bowser Jr. is headless for a second before retreating into his shell. It is recommended to use Big Bowser Jr.

Trivia

 * By way of a glitch or a possible developer oversight, it is possible to spawn Mystery Mushrooms using a Big Magikoopa. Touching the Mystery Mushroom will turn Mario into Small Mario with the same abilities as Super Mario. This is no longer possible after the version 1.03 update.
 * The New Super Mario Bros. U template lacks the same quality as in New Super Mario Bros. 2, which is also a Nintendo 3DS game. 3D elements do not have anti-aliasing effect, and 2D elements are blurrier than in the original game featuring the same art style, being more akin to the original New Super Mario Bros., for the original Nintendo DS.
