Peach's Castle

A bumper floats above the center of this stage. Watch where you jump, or you'll get bumped sky-high! Peach's Castle (, Above Peach Castle), known as Peach's Castle (64) in Super Smash Bros. 4, is Mario and Luigi's home stage in Super Smash Bros. In 1P Game, the player fights a team consisting of and  on this stage. Luigi is also fought here in his unlocking battle in the same game.

Even though this stage did not return in Super Smash Bros. Melee, a portion of the music that plays on it plays during the cutscene where takes 's place in Melee's Adventure Mode. Additionally, a stage taking place in the same location called Princess Peach's Castle is a playable stage in Melee.

Peach's Castle returned as downloadable content in both versions of Super Smash Bros. 4 on July 31st, 2015, alongside Hyrule Castle. Like other returning stages from the first Smash game, some of the textures are slightly higher in quality, but the general overall primitive look of the original is retained. Peach's Castle also returns as a familiar stage in Super Smash Bros. Ultimate, alongside the Princess Peach's Castle stage from Melee.

Stage overview
Peach's Castle has two main platforms, one on top of another. The top platform is a soft platform that slants upwards to the left, and downwards to the right. The bottom platform is a solid platform that slopes slightly downwards on both sides. The bottom platform partially comprises a block that moves left and right, which acts as a semisoft platform. On the top two corners, there are two floating, inward-angled platforms, resembling pinball slingshots, that move slowly up and down and prevent characters from being smashed away too easily. These platforms are very easy to DI off of as well.

The stage has a floating Bumper in the middle above the second platform of the stage. This bumper moves slightly left and right (it remains stationary on 1P Mode though).

In Smash 64, it is difficult for most characters to recover on this stage since the two floating platforms limit recovery to the top platform and there are no ledges that can be grabbed. The moving block platform on the bottom of the stage greatly aids recovery, but it isn't always on the side the player is on. In Smash 4 and Ultimate, however, fighters can now grab onto the bottom platforms.

Ω forms and Battlefield form
In Super Smash Bros. 4, the Ω form removes all features but the main platform, which is extended and flattened.

In Super Smash Bros. Ultimate, the main platform of the Ω form and Battlefield form is similar to SSB4's Ω form; however, it is resized and reshaped to match and, respectively. The design of the three soft platforms of the Battlefield form is based on the wooden soft platform in the center of the regular form.

Hazards Off
In Ultimate, with hazards off, the Bumper is not present, the triangle platforms do not move, and the semisoft platform on the bottom is stationary and is completely centered.

Origin
This stage is loosely based on, with its current design debuting in , where it serves as the game's main hub and has appeared in numerous Mario titles since.

In Super Mario 64, the castle is taken over by Bowser, who takes control of the Power Stars and seals Princess Peach inside the fresco over the castle entrance. A, a Lakitu with a camera at the end of its fishing pole, is first seen flying around Peach's Castle at the beginning of the game and follows Mario for the duration, who controls the camera and allows the player to toggle the view. After Mario defeats Bowser and collects all of the game's Power Stars, the cannon in the castle grounds is unlocked, which will allow the player to access the roof of the castle and find Yoshi and three 1-Up Mushrooms there.

This stage features multiple elements taken from Super Mario 64. The stage mainly takes place around a tower spire resembling the center tower spire on the roof of Peach's Castle. The red carpet staircases on each side of the main platform and the black-and-white checker pattern floor in the middle is similar to the carpeted staircases and the floor patterns found inside of the castle. The stage's background also features an aerial view of Peach's Castle.

The bridges are similar to those found in the course. The design of the triangular platforms in the upper corners are similar to the starting platform in the boss course.

In Super Smash Bros., a Lakitu Bro. will occasionally appear as a background character.

Super Smash Bros.
In Smash 64, for a long period according to the old American ruleset, Peach's Castle was usually considered a counterpick stage in singles. This is because of the inability to grab the edges, meaning that some characters can be gimped or edgeguarded much easier than usual, and because of the Bumper hazard and angled platforms on the side of the stage that can prevent KO moves that would have otherwise KO'd. However, the Bumper can be used for various unique combos, and can also be used by characters such as to escape pressure. The stage is often counterpicked by and  players and the lack of edges that can be grabbed serves as a disadvantage to characters such as  and. However, most recently the stage was banned. In doubles tournaments, the stage is usually banned, due to the listed reasons above along with the fact that the stage is too small.

In the Japanese ruleset, the stage is always banned in all formats as is every other stage except for, due to the reasons mentioned above.

Super Smash Bros. 4
Unlike in SSB, Peach's Castle has been banned since launch. Alongside the great advantage the stage provides some characters compared to others, there are also more legal stages to not consider the stage as potentially legal.

Super Smash Bros. Ultimate
Peach's Castle remains banned in Ultimate for the same reasons as Smash 4. There are also now even more stages, further distancing it as potentially legal.
