'''Stage legality''' refers to the playable status of various [[stage]]s in mainstream [[tournaments]].

==Categories==
In general, all stages fall into one of three categories:

'''Neutral stages''' may be chosen in any game of a set, including the first game. These are also referred to as '''starter stages''' (not to be confused with the [[starter stage|term]] for stages that do not need to be [[unlockable stage|unlocked]] to be used in-game).

'''Counterpick stages''' may be chosen only after the first game of a set, such as games 2 and 3 of a best-of-3 set. Stages in this category tend to give a slight, though not overwhelming, advantage for certain [[character]]s over others, such that it would not be fair to include them in the neutral list. These stages may often (though not always) be chosen for [[counterpick]]ing purposes, hence the name of the category.

'''Banned stages''' cannot be chosen at all. Stages can be banned for several reasons, common reasons including but not limited to:
*Especially poor matchup balance by providing a rather extreme advantage for certain [[character]]s (such as allowing the character to utilise excessive, gamebreaking [[camping]], or utilise infinite [[chain throw]]s, as in the case of {{SSBM|Fox}} in [[Temple]] for the former, or {{SSBB|King Dedede}} in [[Shadow Moses Island]] for the latter).
*Intrusive [[stage hazard]]s that can easily KO players who are knocked into them, or force players to give up an advantage to avoid them. An extreme example of this is [[Gamer]].
*Allowing players to abuse [[glitch]]es in the game.
*Possessing one or more "[[caves of life]]," allowing characters to survive much longer than feasibly possible under usual circumstances, and creating a general over-centralisation on the ability to [[tech]].
*Possessing permanent walk-off [[blast line]]s and walls; the former creates unreasonably powerful camping positions and allows for potential easy [[zero-death]]s that wouldn't occur normally, as well as marginalizing or completely eliminating offstage play (nullifying the value of a good recovery), while the latter also creates powerful camping positions and allow for zero-death or otherwise heavily damaging combos that wouldn't be possible otherwise. Walk-offs and walls that occur only temporarily on a stage are considered detrimental, but acceptable enough to usually not result in a stage's banning by themselves.
*Drastically altering gameplay and the strategies needed to win (such as [[Icicle Mountain]] and [[Mario Bros.]]).
*Possessing elements that causes the stage to be too strenuous on the system's CPU and thus being capable of reducing the game's frame rate mid-match (such as [[Fountain of Dreams]] in ''Melee'' doubles play).

The term '''legal stage''' can also be used to describe any neutral or counterpick stage, or equivalently, any non-banned stage.

In general, due to the wide variety between stages and stage types and the series as a whole not necessarily being designed with serious competitive play in mind, very few stages are balanced enough to be legal for professional competitive play, which is why a majority of stages in all games end up being banned.

Despite the banned stages list, most tournaments feature some variation of the "gentleman rule", a rule that allows players to choose any stage they want, including banned stages, if all players in the match agree to it. This is usually the only way for banned stages to see serious tournament play. However, even with this rule in effect, it rarely sees use to play on banned stages outside a much higher-skilled player letting an opposing more casual or very young player choose any stage they want, as most competitive players never want to willingly play on the banned stages for the same reasons the ruleset had them banned. Even with the rule in effect, TOs may still ban some stages from being played on via the gentleman rule, if the stage has a propensity to delay the tournament by causing much longer matches (such as Temple, [[New Pork City]], and [[The Great Cave Offensive]]).

==Major differences in communities==
There are many [[community]] preferences in terms of stage choices, with there being no agreed-upon standard across all regions on what exactly constitutes a "legal stage", so a stage's legality can be dependent on the region the tournament is in; this is especially true in ''Brawl'' and ''Smash 4'', due to a lack of an officially standardized stage list. [[Pokémon Stadium 2]] in ''Brawl'', for instance, was generally banned in the [[Tristate Area]], while tournaments in [[Texas]] usually allowed the stage to be a legal counterpick choice. 

The commonality of characters can also play a role in what stages are legal or banned. Again in ''Brawl'', the rising prominence of {{SSBB|Meta Knight}} in the [[metagame]] led to stage lists in most regions becoming more restrictive. In the Tristate region, Meta Knight was not banned from tournaments, and as a result, the Tristate tournament scene banned or otherwise restricted stages such as [[Delfino Plaza]], [[Halberd]], and [[Rainbow Cruise]] due to Meta Knight's overwhelming power on such stages. In some regions, however, Meta Knight was not as widely used as the Tristate Area; as such, some of the aforementioned stages have differing legalities, with Halberd sometimes being a starter stage and [[Frigate Orpheon]] going from a banned stage to a counterpick. [[WHOBO 4]], the first American MK-banned major, featured an expansive stagelist that included Delfino Plaza, Halberd, Rainbow Cruise, and Brinstar as counterpicks, even though most of these stages were banned in MK-legal tournaments at the time.

==Stage legality in ''[[Smash 64]]''==
The following is ''Smash 64's'' banlist for stages in tournaments. Until mid-2015, four stages — [[Dream Land]], [[Hyrule Castle]], [[Congo Jungle]], and [[Peach's Castle]] — were legal. Currently, [[Dream Land]] is the only stage that can be used in tournaments. However, with tournaments switching from the vanilla version of the game to the [[19XX]] mod, in some tournaments like {{Trn|GENESIS 5}} or {{Trn|GENESIS 6}}, the stages [[Duel Zone]] and {{SSB|Final Destination}}, which weren't available without hacking, have seen some tournament presence in doubles, though this is generally rare. 

More recently, [[Smash Remix]] has allowed for certain hacked stages in tournaments, such as Zebes Landing (a version of Dream Land without wind), and even stages with a different layout, like 64 versions of [[Smashville]], [[Yoshi's Story]], [[Pokémon Stadium]] and others.

|-
| [[Pokémon Stadium]] (frozen)
| style="background:#ffefbf" | Sometimes legal
| style="background:#ffefbf" | Sometimes legal
| The lack of transformations make for a more balanced and consistent experience. Unavailable without modding. Used in modern online events due to stage transformations causing desyncs when playing online with [[Project Slippi]] and in some offline locals and major tournaments such as [[Riptide]].

==Stage legality in ''[[Brawl]]''==
:''For finer-grained status descriptions, see [[Tournament legal (SSBB)]].
''Brawl'' had a highly fragmented and argumentative community when it came to which stages should be legal. As a result, the stage legality list is significantly messier than the previous two games, with most stages being disputed in one way or another. Additionally, a stage's legal status was heavily influenced by {{SSBB|Meta Knight}}'s legality, as he tends to gain even more drastic advantages on many fringe stages. Thus tournaments that banned Meta Knight tend to allow more stages than tournaments that kept him legal.

Meta Knight's advantage on the stage is so large that it's universally banned nowadays in Meta Knight legal tournaments, but it may see legality in Meta Knight banned tournaments.
|-
| [[Castle Siege]]
| style="background:#ffffbf" | Counterpick
| Second [[stage transformation]] and the transition between stage transformations have walk offs; second stage transformation has no access to a bottom blast line and thus does not allow offstage gameplay; second transformation is very large and allows ease of platform camping.
|-
| [[Corneria|Corneria (Melee)]]

| Close blast lines and an abnormally low ceiling, which gives a disproportional advantage to vertical finishers; excessive camping/stalling behind the big fin; fin allows for wall infinites
|-
| [[Delfino Plaza]]
| style="background:#ffffbf" | Counterpick
| Several stage transformations have walls and/or walk offs; primary section of the stage on the hovering platform allows sharking. Meta Knight legal tournaments that don't intend to be as limited as the Japanese ruleset may ban the stage, solely due to Meta Knight's prowess on the stage.

| [[Frigate Orpheon]]
| style="background:#ffffbf" | Counterpick
| The stage flipping between its two transformations is susceptible to causing what is commonly seen as unwarranted self destructs; the first stage transformation has no grabbable ledge on the right side of the stage, giving a disproportional disadvantage to characters with tether recoveries and other characters who heavily rely on the ledge to recover. Meta Knight legal tournaments that don't intend to be as limited as the Japanese ruleset may ban the stage solely due to Meta Knight's prowess on the stage.
|-

| Stage is overly large; irregular stage design forces major gameplay changes; high camping/stalling potential
|-
| [[Jungle Japes]]

|-
|[[Onett|Onett (Melee)]]
| style="background:#ffefbf" | Infrequently legal
| Irregular stage design; frequent stage hazard in cars disrupt gameplay; walls allow infinites; walk-off blast lines; no lower blast line
|-
|[[Pictochat]]
| style="background:#ffefbf" | Infrequently legal
| The order in which the drawings appear on the stage is random, and the time to prepare for each drawing is minimal; some drawings can cause a player to be KO'd or fail a recovery against their control (such as the Eyes drawing preventing a recovering character from grabbing the left ledge, or the Gusty Gus drawing appearing and stage spiking a character after they have been knocked back); some drawings create walls, allowing wall infinites; some drawings promote camping; overly powerful stage hazards; numerous glitches can occur on the stage, such as the [[Earthquake glitch]] and the [[Spin glitch]].

| Thin lips at the edges of the stage; water transformation has a solid windmill that can create caves of life; walls in fire and rock transformations can lead to camping
|-
| [[Pokémon Stadium 2]]
| style="background:#ffefbf" | Infrequently legal
| Stage transformations can cause what many players see as large, disruptive gameplay changes; wind transformation reduces gravity; ice transformation has slippery terrain; electric transformation has large, fast-moving conveyor belts that disrupt usual gameplay; all transformations but ice have powerful [[camping]] positions and high potential for stalling. One of the most heavily debated stages, as many players have vouched for the stage and argue its transformations to not be as disruptive as commonly claimed, or in some cases that its transformations are even beneficial to gameplay. Many other players, however, adamantly refuse to touch the stage, and thus it remains commonly banned.
|-
| [[Port Town Aero Dive]]
| style="background:#ffefbf" | Infrequently legal
| Randomness of the stage; overly powerful stage hazards in the cars (which can KO under 50%); cars can be difficult to see coming due to the colors and their speed; main platform has no grabbable ledges
|-
| [[Rainbow Cruise]]
| style="background:#ffefbf" | Infrequently legal
| Scrolling stage; some portions of the stage have no grabbable ledges; some portions of the stage have walls, allowing wall infinites or walk-off blast lines, creating an over-centralisation on horizontal KO moves; poor matchup balance, where air-based characters have a significant advantage, most notoriously Meta Knight. Meta Knight's advantage on the stage is so large that it's universally banned nowadays in Meta Knight legal tournaments, but it may see legality in Meta Knight banned tournaments.

| Scrolling stage; gives a disproportional advantage to characters with fast, high jumps; punishes characters who rely on [[Tether|tether recoveries]]; first spike is an OHKO stage hazard if not teched; irregular stage design forces major gameplay changes, given an emphasis on keeping up with the stage instead of fighting
|-
| [[Shadow Moses Island]]
| style="background:#ffbfbf" | Banned
| No lower blast line; walls block access to side blast lines when not destroyed; over-centralisation on teching; game mechanics change too quickly when walls are destroyed or up, giving a disproportional advantage to vertical finishers when the walls are up, and giving that advantage to horizontal finishers when they're down; walls allow for wall infinites; walk off blast lines when the walls are destroyed; a glitch can allow characters to stay on the other side of the walls when they rebuild, allowing the character to safely camp there until the wall is destroyed again
|-
| [[Skyworld]]
| style="background:#ffbfbf" | Banned
| Impassable platforms; cave of life in centre of stage creates an over-centralisation on teching; the combination of "supersoft platforms" and the aforementioned impassable platforms results in frequent onstage [[stage spike]]s, that cause frequent low damage KOs on the stage from what should be a neutral position; potential slowdown in doubles
|-
| [[Smashville]]
| style="background:#dfffbf" | Starter
| 
|-
| [[Spear Pillar]]
| style="background:#ffbfbf" | Banned
| Randomness of [[Pokémon]] attacks; overly powerful stage hazards caused by Pokémon; Pokémon can cause disruptive changes in gameplay, such as slowing down time, reducing gravity, and reversing control; stage design allows the potential for circle camping; lower area of the stage provides a large cave of life
|-
| [[Summit]]
| style="background:#ffbfbf" | Banned
| Terrain is [[slippery]]; lower gravity occurs at one point of the stage; one-hit KO stage hazard of the [[fish]], which quickly drags characters beneath the lower blast line with no hope of survival; ledges are not grabbable, giving a disproportional disadvantage to characters who rely on ledges to recover, especially those with [[Tether recovery|tether recoveries]]; lower area provides a cave of life; stage design allows the potential for circle camping
|-
| [[Temple|Temple (Melee)]]
| style="background:#ffbfbf" | Banned
| Overly large; large cave of life in lower area over-centralises gameplay on teching; multiple areas allow for run away and circle camping; excessive stalling potential; gives an extreme advantage to fast characters (most notably Fox)
|-
| [[WarioWare, Inc.]]
| style="background:#ffbfbf" | Banned
| Random bonuses from Microgames have an over-centralising effect, to where someone can win by being luckier with the bonuses; walk off blast lines during microgames; overly powerful stage hazards during microgames
|-
| {{SSBB|Yoshi's Island}}
| style="background:#efffbf" | Counterpick/Starter
| Shy guys can disrupt projectiles; The Blarggwich can assist in recoveries, but arrival and departure times are random.
|-
| [[Yoshi's Island (SSBM)|Yoshi's Island (Melee)]]
| style="background:#ffefbf" | Infrequently legal
| Rotating block platforms create caves of life; walk off blast lines; marginalizes offstage skills; blast lines are abnormally close to the stage
|}

Additionally, the community at large has never considered the [[sample stages]] in the [[Stage Builder]] as official stages, and as a result, they are all considered banned. Despite this, none of the three stages would be theoretically legal in any ruleset: Hole has no grabbable ledges from the outside and contains a powerful camping location in the lower-left spikes; Bath frequently lacks the lower blast line and has walls that block the horizontal blast lines and allow for infinites; and Maze's irregular design promotes camping, circle-camping, and stalling, and the stage's architecture creates caves of life. Arguably, a large number of setups also often lack the stages, as they interfere with the loading of mods via the [[Smash Stack]].

==Stage legality in ''[[Project M]]''==
The following stages are legal in the ''PMBR 2018 Full Recommended Ruleset'' [https://docs.google.com/document/d/1g9WicZyRo_TRauu4XfuUjD-itUji2p4SAa1pPHuL0Zs/edit]

For counterpicks, the winner of the previous game strikes 2 legal stages after character selection and the loser picks one of the remaining ones.

==Stage legality in ''[[Super Smash Bros. Ultimate]]''==
<!-- Keep in mind that 1) hazards are turned off for tournament play and 2) this list is based on rulesets of competitive tournaments and not by what you consider to be "playable stages" 3) Being similar to a legal stage does not make a stage a legal alternative or affect 2) -->
''Super Smash Bros. Ultimate'', having the most stages in the series and the option to turn stage hazards off, has the most potentially legal stages of any ''Smash'' game. Since the stage list and hazard toggle were revealed, players and TOs have been debating the stage list for the game, and have yet to come up with a definitive answer. Major tournaments have largely erred on the side of having relatively large (eight to ten) stage lists, but some regional tournaments have already cut back to four to six legal stages.

This is mainly due to Town and City usually being the only transformative stage in most competitive stage lists, as well as having a transformation which is duplicative of Final Destination.

|-
|[[Mementos]]
|style="background:#ffefbf" | Infrequently legal || Slight slope in center of stage, asymmetrical layout, top platform can promote camping, stage altogether is large and paired with large blast zones.

|-
|[[Cloud Sea of Alrest]]

|-
|[[Mishima Dojo]]
|style="background:#ffbfbf" | Banned || The stage has large walls on either side and a ceiling which can allow for infinites. While the walls and ceiling are destructible, the blast zones beyond them are close to the stage.
