List of Mario Kart Tour pre-release and unused content

This is a list of pre-release and unused content for Mario Kart Tour.

Closed beta
On April 23, 2019, Nintendo opened applications for participating in a closed beta test of Mario Kart Tour to users in North America and Japan, which began on May 22, 2019 and ended on June 4, 2019. The following lists the features included in the beta version of the game. Several of the characters, karts, and gliders listed were not made available in the final game at launch.

General

 * Rubies were originally emeralds.
 * An element seen in other free-to-play games that was included in the closed beta was a stamina bar consisting of five hearts total. One heart would be consumed every time a player raced, and once the stamina was depleted, players would not be able to play until it recharged. Players would replenish hearts when they leveled up, if they waited out the timer, or if they purchased hearts with rubies.
 * Originally, there was no way to speed up the unlocking process for the cups restricted by timers. In the final game, this can be done using quick tickets.
 * The Daily Selects Shop was only 6 items, not 9.
 * Players could receive Metal Mario, B-Dasher, and the Gold Glider in the final tour gift, which was the first spotlight pipe.
 * Combo bonuses were not implemented.
 * Higher tier karts originally increases speed, while higher tier gliders only increases item-luck.
 * Music and sound effects were different from the final game.
 * The menu had a different arrangement.
 * The jingle when acquiring a Normal item or Grand Stars was different.
 * The countdown sound effect was taken from Mario Kart: Double Dash!! up to Mario Kart 7. In the final game, the sound effect is instead taken from Mario Kart 8.
 * Whenever it is the Final Lap, the text says FINAL LAP!; in the final version, it says 2/2 (or 3/3 for 3DS Rainbow Road).
 * The rear view button was placed in the top right corner, below the options button.

Characters
Most of the characters retain their special items in the final game; however, Baby Peach, Baby Daisy, Baby Rosalina, and Lemmy's special items are replaced by the Bubble, Morton's special item is replaced by the Giant Banana, Larry's special item is replaced by the Boomerang Flower, King Boo's special item is replaced by the Lucky 7, and Ludwig's and Rosalina's special item is replaced by the Dash Ring. Additionally, in the beta, both Rosalina and King Boo were classified as High-End characters, whereas in the final version, they are classified as Super characters instead.

Cups
The beta only featured one tour, named Retro Tour (known as Beta Test).

Karts
Most of the karts retain their rarities in the final; however, in the beta, the Soda Jet and Super Blooper were both classified as Normal karts, and the Blue Seven was classified as a High-End kart, whereas in the final, they are all classified as Super karts.The Egg 1 also hasn't been added to Mario Kart Tour as of the Valentine's Tour.

Gliders
None of the gliders' rarities changed from the beta to the final game.

Characters
After Red Koopa (Freerunning) was added in the London Tour, there was an additional texture set for the Green Koopa.

Karts
Some karts have specific files for their positions on certain karts. Most of these karts are in the game, but there are references to several unused karts, including the Mario Kart 8 appearance of the Blue Falcon (BFalcon8) and the Cat Cruiser (CatC). Additionally, a model of the Green Kiddie Kart with a red and blue color-scheme resembling Mario's overalls can also be found.

Tracks
Several text strings referencing objects of tracks not in the game can be found in the files.

Sprites
When the Para-Wing was added in the London Tour, a sprite was added in the files which appears to be identical to the kart, except with different tires being equipped, instead being the new tires seemingly based off of those of the Pipe Frame, which were also used by the Koopa Dasher.

Icons
Some unused icons know as BoostItem, ItemExchange, PartsScoreUp and PartsSkillUp can be found in the game's files. The BoostItem icons also have icons of them on a ticket.
