The stage is set in Minecraft's Overworld and has a largely standard design, being a flat platform with edges that extend to the lower blast zone. Different materials for mining can be found along the main stage, and breakable blocks of various kinds appear as obstacles. It features a day/night cycle. Two of a randomly selected farm animal (two cows, sheep or chickens) will appear in the background as soon as the stage starts. Some biomes may feature Villagers that perform farmwork during the day. They can be seen occasionally turning to fighters and watching the battle when close. At nighttime, Villagers retire to their homes and two different types of monsters will appear; these may be any pair of a Zombie, an Enderman, a Skeleton, or a Spider, and do not affect gameplay. When morning starts, the monsters will either catch fire and burn up or simply retreat depending on the monster, repeating the cycle.
Normally, the stage randomly loads in different biomes, but a specific biome can be chosen by holding specific buttons before selecting the stage, similarly to Boxing Ring. The stage's biome affects which obstacles will appear. Any obstacles can be destroyed through attacks, including mining, and will not respawn. However, the materials found through mining on the main stage will always be the same regardless of biome.
Ω form and Battlefield form
In its Ω form and Battlefield form, the stage always loads in the plains biome, but retains its day/night cycle. It is largely the same other than lacking any hazards and being resized and reshaped to match Final Destination and Battlefield, respectively. The Battlefield form's platforms are similar to those found on the birch forest, savanna, and stone shore biomes. The main stage is set on a grass path rather than varied terrain, since the terrain of Battlefield and Ω stages does not affect which materials can be mined. Unique to this stage, the 8-player Ω form's main platform is completely different from the regular Ω form's platform, rather than simply being a scaled up version of it, presumably for consistency with the size of the stage's blocks.
With hazards off, the stage will still load one of the six biomes, but all breakable obstacles are removed. The platforms found on the birch forest, savanna, snowy tundra, and stone shore biomes still appear.
In Minecraft, worlds are created through by choosing the "Create New World" option on the world select screen. Worlds are generated based off of seeds, a value that includes negative and positive integers. Seeds are either randomly generated by an algorithm, or can be manually generated by the player by typing strings of letters and numbers in the seed bar.
Within a randomly-generated world, there are a number of biomes, which determine the weather, terrain, and mobs that will spawn in that part of the world. The variations of this stage represent a selection of the biomes.
Villages are unique structures that can be found in a variety of biomes, including Plains, Savannas, Snowy Tundras, and Taigas. The Plains variant, which appears in Smash, is the type that has been in the game the longest and represents the most generic village, where villagers farm in wooden houses. Villages often contain loot, but it is possible to trade with the villagers, as well. At night, all villagers will retreat into their homes to sleep away from Zombies lest they be turned into Zombie Villagers or otherwise killed by one.
Due to its recent release, as well as the general suspension of tournaments during the COVID-19 pandemic, there has not been a decisive conclusion on Minecraft World's legality. As the breakable blocks are removed with hazards off and the specific layout can be chosen, there have been talks of making specific forms of the stage legal—specifically the savanna, forest, tundra, and/or stone shore biomes. However, the stage also provides a mild advantage to Steve due to being designed with his mining mechanic in mind, and its size has proven somewhat controversial.
