Terrain

The grass stage of Pokémon Stadium has many grassy and wood-based floors.

Sections of Summit have slippery floors of ice.

Terrain is the type of material that a platform of a stage is composed of. Super Smash Bros. Melee, Super Smash Bros. Brawl, Super Smash Bros. 4, and Super Smash Bros. Ultimate are all known to use different types of terrain in their stages, and each game introduces new types of terrain for new uses.

Terrain can produce different footstep noises or visual effects when characters and other objects step or land on it. The main functional effect of terrain is traction; some types of terrain can increase or decrease traction, which means characters and objects will slide less or more, respectively, from movement on the terrain. There are also some types of terrain that are used to damage and launch players upon contact.

Terrain also affects the behaviour of some special moves. In Melee, Yoshi's ability to accelerate during Egg Roll and Jigglypuff's ability to turn around during Rollout are affected by terrain. In Brawl, Olimar's Pikmin Pluck has its speed and the type frequency of resulting Pikmin affected by the terrain he is standing on. In Ultimate, terrain affects what materials Steve will obtain through Mine, except for Battlefield form and Ω form stages, which have a standard selection.

Melee terrains

The different types of terrain have little effect on gameplay outside of cosmetics, with the exception of ice and other slippery surfaces. However some special moves such as Egg Roll and Rollout may be minorly influenced by terrain, with Rollout being able to turn around an additional time on grass terrain.

The colours in this table are taken from Melee's debug mode.

Brawl terrains

The frequency of different types of Pikmin from Pikmin Pluck is based on the type of terrain that Olimar is standing on. Ice Climbers are unaffected by any terrain that reduces traction.

Smash 4 terrains

Smash 4 has 33 different terrain types. Most of them only differ cosmetically, but a few have different traction, which is listed as a multiplier in the table below. Several of the terrain types are unknown and may be dummied leftovers from Brawl, while others are known but have unknown usage and may be unused.

In Smash 4 onwards, Olimar's Pikmin Pluck is not random and is not affected by the type of terrain he is standing on.

Terrain	Traction	Description
Basic	1	The default terrain type. Known internally as "None".
Rock	1	Relatively rare; known to appear in Castle Siege part 3 and the rock of Pirate Ship.

Unknown 3	1	Unknown. Appears to use sound effects named "bomb". Could possibly be linked to Target Blast.

Ultimate terrains

Ultimate has 44 different terrain types, with one added in a DLC stage. Most of them only differ cosmetically, but a few have different traction, which is listed as a multiplier in the table below. It appears that most terrain types in Smash 4 carry over to Ultimate, but notably, Grass no longer has increased traction. Additionally, Steve can mine different materials depending on which terrain he is on, though it is less affected by specific terrain than Olimar's Pikmin were in Brawl.

Terrain	Traction	Description
Basic	1	The default terrain type. Known internally as "None".
Rock	1	Used for rock surfaces.
Grass	1	In general, any sort of plant surface.
Soil	1	Earth that's not covered with anything.

Soft	1	Used for soft surfaces, such as the mushrooms on Golden Plains.
TuruTuru	0.1	Appears unused. "Turuturu" is onomatopoeia for a smooth or slippery surface. Reduces traction.
Snow	1	Appears unused, due to a lack of snow on stages.
