Builders must choose to create a small, medium, or large stage, which will affect the number of parts that can be placed and the location of blast lines. Next, the builder selects a theme: a mountain, a ruined building, or a futuristic chamber. Each theme has its own set of special stage elements, which allow for slight variations in stage design depending on what theme is used. The final step before building is picking a song, which can be any track that has been unlocked. However, only one song may be used per stage. Then, the terrain must be set. There are different structures and building materials the player can use depending on the background chosen earlier. There are also three different sizes for most of the structures. The player, however, is limited in the number of parts they can use per stage. Each piece used will use up so much memory for the map, and some pieces take up more memory than others. Once ready, the player can test the stage through the editor (only Mario can be used though), then switch back to the editing screen if they want to make any more changes. The players can also send stages to their friends, and they are compatible with SD cards. Stages can only be had as long as there is room in the internal Wii memory and SD card.
In addition, this mode comes packed with interactive terrain objects. For example, players can make platforms that will move up or down, or side-to-side. This will create many options for map makers. There are also "traps," like spikes for example, that can be implemented into the map. Ultimately, in this mode, the players are limited by their own level of creativity (and memory usage). Many people have even modeled stages after Super Smash Bros. and Super Smash Bros. Melee stages.
Types of Parts
Types of parts the player can use in this mode range from standard pieces, like blocks and ramps and stairs, to structures, like, ferris wheels, trees and mushrooms and rock arches, to features, like the Drop Blocks, which begin falling if stepped on long enough. Drop Blocks eventually respawn, and can only be activated from above, making it possible to make one-way doors of a sort. However, drop blocks will drop if items are spawned on them. To get the true effect of a one-way door, one must turn off items. There are also ice blocks. Walking/running on them lowers characters' traction (excluding the Ice Climbers) and there is higher chance of tripping. Also the ledges of ice blocks can't be grabbed, which may lead to deaths if not aware of this. If the building area contains only features or structures (excluding the special blocks), the players may get an error message that says they must add horizontal platforms.
They are divided in:
There are three categories of parts: Floors, Structures and Features. In this following part the order will go by name, use, if it varied with the different theme (not texture) and how many cubic squares it uses.
- Platform: A drop through platform, texture, 1x1
- Diagonal Platform: A slanted drop through platform, texture, 1x2
- Short Platform: A halfsized drop through platform, texture, 1x1
Block: a normal block, Probably most used Stage Builder Part, texture, 1x1
- Stair Block: A simple stair block; able to walk up properly, texture, 1x2
- Slanted Block: A right-angle triangle shaped block able to be walked on; characters slide downwards when on it, texture, 1x2
- Long Slanted block: A bigger version of the Slanted Block, texture, 2x2
- Mountains: Slightly slanted object, 2x4
- Ruins: Pillar, good for wall jumping, 3x3
- Chamber: a slanted block, quite simple, 2x4
- Mountains: A stubby platform simply used as a stepping stone or a perch to spam projectiles, 2x3
- Ruins: Stone slanted block, flat then slanted on the right side, 2x4

- Mountains: a tree with low left and upper right branches to perch on, 3x4
- Ruins: slanted stone block, 2x4
- Chamber: little stepping stone like platform, similar to the Mountains's second structure, 2x3
- Mountains: Three mushrooms that act as solid platforms, The largest at the top/middle, the Normal size at the middle/right and the smallest at the bottom/left, 3x4
- Ruins: Small pillar with slanted platform, top platform drop through,
- Chamber: A straight platform with end points that stop any player from falling by running, 2x4
- Ruins: Three pillars together, similar to the mountain's 6th part, 3x4
- Chamber: A special platform that has a pass-through top, a thin middle wall that separates the two sides, all in the shape of an uppercase I, 3x4
- Mountains: A see through platform similar to Norfair's safe area, 3x4
- Ruins: A little house with a floor on the left, home to the right and a chimney to perch on, 3x4
- Chamber: A pillar, good for wall-jumping that has a little top to stand on, 3x3
- Mountains: A pillar with a face, good for wall-jumping, 3x3
- Ruins: A see through platform with a wall on the right side, and a pass-through top, 3x4
- Chamber: A trapzoid shaped block, used on top of 'tower' stages, 2x4
- Moving platforms: One goes up and down and the other goes left and right; drop through, no, left and right 3x1, up and down 1x5
- Ice block: Causes more Prat Falls and makes players slide even when they're not moving, no, 1x1
- Drop block: Drops after about 2 seconds if a character's standing on it and drops until offscreen, no, 1x3
- Spikes: Causes 15 damage when hit by spike, computers hit these a lot and struggle to get away, no, 1x2
- Ladder: Simple climbable ladder, no, 1x1
There are also certain parts and features that can be unlocked to use in the Stage Builder.
There must be an opening in the stage to fall out of in order to unlock parts A, B, and C.
In other words, 15 CD factories can't be made to unlock Edit Parts C. Players must exit out of stage builder when done to unlock the challenge.
- Spring: Green or Orange spring, 1x2
- Conveyor belt: Moving conveyor belt moves all things in one direction, no, 2x2
- Rotating Platform: Spins four platforms in a Ferris Wheel motion, no, 4x5
- Edit Parts A: Play 10 times or more on custom stages.
- Edit Parts B: Create 5 or more stages in stage builder (not including the 3 sample stages).
- Edit Parts C: Create 15 or more stages in stage builder (not including the 3 sample stages).
The stage builder in Smash Bros. for Wii U has been significantly upgraded. The new features are as follow:
- 5 new backgrounds (Skyworld-like sky, outer space, clear sky and ocean, noon city with Smash ball logo and volcanic)
- Freeform draw
- Ability to colour and give texture to drawn platforms
The parts to help you create your stages include:
- Springs (Large and small)
- Cannons (Weak and strong)
- Moving Platform (Large or small)
- Magma (Thick or thin)
- The futuristic chamber background is similar to the background in the Subspace Emissary's Research Facility II, where players fight the two False Samuses or when Samus first encounters Ridley. Similarly, the ruins background can be seen in the distance behind part of The Ruins.
- A computer based stage editor, called Stage Studio, has been created. It allows the user to create a stage and bypass some of the usual stage builder restriction. (It enables blocks to overlap, increased number of blocks can be used, etc.) It also allows players to use the beta block, also known as the "bump" which is just a bump. If a player decides to edit a stage that has a bump on Stage Builder, the platform sprite will show instead of the bump. When a player tries to select a bump or tests the stage, the game will freeze.
- The stage background with the haunted house is the very same one as played in the Subspace Emissary when first playing Ivysaur.
- Some glitches, such as the Jump Through Walls Glitch and the Teleport Glitch, have been found while creating custom stages. Several videos in the internet have proved this.
