Mario Kart Tour

Mario Kart Tour is a mobile game in the Mario Kart series. First announced during a financial briefing on January 31, 2018, it is the third Mario mobile game overall, following Super Mario Run and Dr. Mario World, the ninth main installment in the Mario Kart series, and the sixteenth installment overall. Like Super Mario Run, it is free-to-start from the App Store and Google Play. Unlike Super Mario Run and similar to that of Dr. Mario World, the game more heavily incorporates a free-to-play microtransaction mechanic, where players have restrictions and timers unless they spend some of the various types of currencies in-game, as well as having in the form of items being launched out of pipes. The game reuses many assets from Mario Kart 7, Mario Kart Arcade GP DX, and Mario Kart 8, as well as returning gameplay mechanics such as gliding and character specific special items. In addition, the game introduces some features new to the Mario Kart franchise such as reverse tracks and ability to deploy a large amount of any item during a race, including Spiny Shells and Bullet Bills. On April 23, 2019, Nintendo opened applications for participating in a closed beta test of the game to Android users in North America and Japan, which began on May 22, 2019 and ended on June 4, 2019.

The game officially launched for both iOS and Android devices on September 25, 2019 in 163 territories, which covers nearly the same roster of availability as Super Mario Run, with the exceptions of Belgium and Vietnam, the former of which banned games with loot boxes in 2019. Users who pre-registered acquired the game a day early. Unlike previous Mario mobile games, a Nintendo Account is required to be playable.

On October 31, 2019, Nintendo announced a multiplayer beta test planned for December 2019 exclusive to Gold Pass members.

Gameplay
The goal of the game is to be in first place at the end of each race, using items obtained by driving through Item Boxes. The game is played in a portrait position, while the phone's touch controls are used to play the game, such as dragging the finger across the screen to steer the kart. There are three ways the player can make turns. For the phones supporting it, the gyroscope can be used to steer. The player can choose what action is started when tapping and sliding the fingers on the main area of the screen, with the other action being performed by tapping a small circular button at the bottom and then sliding the fingers if needed. The main setting has the driver jumping every time the screen is tapped, allowing the kart to drift by sliding the fingers. In the other configuration, the kart does not jump when tapping the screen, which results in it steering when sliding the fingers on the screen. After steering for a while, the kart starts autodrifting and charging Mini-Turbos and Super Mini-Turbos, but not Ultra Mini-Turbos that are only charged when drifting. Similarly to Mario Kart 8 Deluxe with auto-accelerate and smart-steering enabled, karts accelerate automatically and can steer players away from walls. The intensity of smart-steering can be changed in the game's settings.

The game's mechanics are based on Mario Kart 7 and most of the Retro Courses are also available as either normal or retro courses in Mario Kart 7. A few features from Mario Kart 8 that required substantial changes to the game, such as Bikes, ATVs, anti-gravity, and 12-player races, are missing, while the 200cc class is present. Other features from Mario Kart 8 Deluxe, such as auto-accelerate, smart-steering and Ultra Mini-Turbos, return. Unlike previous games the player cannot customize their tires.

When a race is completed, the player will be awarded with Grand Stars, experience points for the used driver, kart and glider, and coins. If the player finishes in the top three places, the gauge to level up will be filled, while if the placement is 5th or lower, the gauge will be dropped. When the gauge is already empty, however, the player will not go level down. Grand Stars are awarded depending on whether a certain point threshold has been reached. Experience points for the driver, kart and glider are awarded depending on the placement. The coins obtained are those collected during the race, plus one additional coin for every 1,000 points obtained during the race. Each day, it is possible to obtain up to 150 experience points for drivers, karts and gliders and up to 300 coins by racing. When those limits are reached the player cannot obtain experience points or coins by racing until the next day. In order to continue gaining experience points or collecting coins, the player can use point-boost tickets for the former and can play Coin Rush or get rewards from challenges for the latter. Filling up the gauge to level up gives a reward to the player, increases the points earned when reaching a specific placement in the race and, when level 7 or level 12 are reached, allows the player to buy more items in the shop.

The game features Tour Challenges and Gold Challenges, which reward Grand Stars, and Standard Challenges, which reward rubies, the main premium currency of the game.

Another premium item, bought with real-life currency according to a monthly subscription model, is the Gold Pass, which grants access to the 200cc engine class, additional items from Tour Gifts and Gold Challenges.

Each driver, kart and glider have favored courses, on which they offer advantages if they are used. Each course has three tiers for each driver, kart and glider. Third tier drivers receive one item from every Item Box, second tier drivers receive two items and first tier drivers receive three items. Second tier karts give a bonus points multiplier of 1.5 and first tier karts give a bonus points multiplier of 2. Second tier gliders increase the time between two point-gaining actions to count as combo and give a combo bonus multiplier of 2 and first tier gliders increase the combo-time even longer and give a combo bonus multiplier of 3. The player can enter a Frenzy by obtaining three of the same item at the same time, which allows the player to temporarily use that item an infinite amount of times in addition to granting them invincibility. Super and High-End drivers, karts and gliders have a higher number of points gained when choosing them and more preferred courses. In addition, drivers have their own special items, similar to Mario Kart: Double Dash!!'s item system. Karts have their own driving-related bonus such as increasing the effectiveness of drafting, while gliders increase the likelihood of obtaining a certain item and the points gained when using this item. All drivers, karts and gliders can be leveled up, and they all come with upgrades when done so.

The courses the player can play depends on the tour, which changes every two weeks. Each tour has sixteen cups, and adds new drivers, karts, gliders and courses, including one course that is new to the series. Each cup contains three races and one bonus challenge. Bonus challenges require the player to beat a certain goal with a certain character, kart and glider. Once each of the courses and the bonus challenge is played and enough Grand Stars are obtained, the player can move on to the next cup. Tour Gifts appear between cups which give the player items if enough Grand Stars are obtained. Every week, one of the tour's cups is a ranked cup. In a ranked cup, the player is placed on a leaderboard based on their overall score in the game against nineteen other players. The player gains a reward and may increase in tier at the end of the week if the end position is within the best ten places.

Each tour has three sets of Tour Challenges. The first one is unlocked from the tour's beginning, the second one unlocks after the one week, and the third one is exclusive to Gold Pass members.

Points
Points are collected during standard races and are used to gain Grand Stars and to rank the players, both overall and in ranked cups. There are three ways of obtaining points in races: base points, bonus points, and position points.

Base points
Base points are given at the beginning of the race and are the sum of the base points of the character, kart and glider selected. They range from 800 to 1600 points. The base points can be increased through experience points obtained at the end of the races or through point-boost tickets that provide 50 experience points each. The experience points are used to fill a gauge that when filled will increase the base points until the maximum amount has been reached. The amount of experience points needed to fill the gauge increases every time the gauge is filled.

Bonus points
Bonus points are points awarded every time a special event happens during the race. Said event might be a Jump Boost, gliding for a certain amount of time, finishing the lap in a certain position, hitting opponents or hazards, and various other cases. If a further event happens at least before two seconds have passed from the previous one, the combo indicator goes up and the points obtained are increased. The actual time that can pass between one event an the next can be incresed by choosing a glider of a higher tier in the course, by choosing a glider of higher rarity or by leveling up the glider. The number of points given is calculated as follows:

Points = (base points of the event × multiplier due to kart tiering in the course × multiplier due to kart rarity and skill level) + combo bonus + bonus point boosts + eventual increase from kart's special skill + eventual increase from glider's special skill

The combo bonus is calculated as follows:

Combo bonus = multiplier from glider's tiering in the course × Min{combo count - 1 ; (cc of the engine class) / 10}

For the purpose of the calculation, 200cc is considered the same as 150cc.

The bonus point boost is calculated separately for the driver, kart and glider chosen, that are in the first tier of the course, as follows:

Bonus point boost = base points × (skill level - 1) × [(cc of the engine class) / 30000]

In this case as well, 200cc is considered the same as 150cc. If more than 200 events happen, the bonus point boost is not applied from the 201st event onward.

Position points
Position points are awarded to the player depending on their placement at the end of the race. They are calculated as follows:

Position points = [(position points due to the level of the player + engine class bonus) × position multiplier] + bonus point boosts for position

The bonus point boost for position is calculated separately for the driver, kart and glider chosen, that are in the first tier of the course, as follows:

Bonus point boost for position = base points × (skill level - 1) × number of events happened in the race × position multiplier × [(cc of the engine class) / 30000]

As in the other cases, 200cc is considered the same as 150cc.

The engine class bonus is the following:


 * 50cc: 0 points
 * 100cc: 200 points
 * 150cc: 400 points
 * 200cc: 400 points

The position multiplier depends on the placement at the end of the race and works as follows:

Grand Stars
Grand Stars are the main collectibles related to individual tours. Up to five of them can be earned by reaching certain points threshold in each standard race and up to three of them can be earned by clearing specific goals in each bonus challenge. Furthermore, clearing each day the daily challenge will warrant a Grand Star, and clearing Tour Challenges and Gold Challenges will reward the players with Grand Stars as well. Finally, using a star ticket will reward a Grand Star per ticket used.

They are used to unlock items in the cup bar of the course selection screen, namely cups and gifts. When the last gift will be obtained, coins will be rewarded in place of Grand Stars, and when a new tour starts, the Grand Stars obtained are reset to 0.

Rubies
Rubies are the main premium currency of Mario Kart Tour. Beside being bought with real life currency at the Shop, rubies can be obtained as daily login bonus, as player level up bonus, as part of tour gifts, as reward for the ranked cup and as reward for the Standard Challenges.

Rubies can be used in two different ways: two buy launch pipes and to play Coin Rush mode.

Launch pipes randomly shoot out a driver, kart or glider, all which have their own rarities. A counter keeps track of the number of Normal, Super and High-End items obtained from a certain pipe, so that up to a certain number of Normal, Super and High-End items can be obtained. It is possible that a player obtains an item from a pipe that already has been obtained. When this happens, the level gauge of that item will be increased by one unit. A pipe contains 100 items, including one featured High-End character, kart and glider which are guaranteed to have been launched from a pipe if the player emptied it. A new pipe replaces the former one each week, and the player can reset a pipe manually as well.

The probability of obtaining a certain type of item from the pipe is (number of items of that type remaining in the pipe)/(total number of items remaining in the pipe), the probability of obtaining a specific item is (probability of getting an item of the type of the desired item)/(number of available items of the same type of the desired item).

Rubies can also be spent in Coin Rush where the player can obtain a great amount of coins. Over 300 coins are found in the course. For each tour, another course is available in Coin Rush and Gold Mario is the regular driver. The coins obtained from Coin Rush are multiplied by a certain number, depending on how many rubies a player has spent.

Coins
Coins are collected during a race and rewarded for the amount of points obtained during said race, up to 300 per day. In a single race, the amount of coins earned is

Coins earned = coins obtained during the race + floor((total points earned in the race)/1000)

The coins obtained during the race are capped at 99, while no cap on the coins obtained through points is known yet.

Beside this main way of obtaining coins, coins can also be obtained in Coin Rush and in several rewards, such as obtaining three Standard Challenges, Tour Challenges or Gold Challenges in a row, column or diagonal, in gifts, as daily login bonuses, as player level up bonuses, as rewards for ranked cup placement.

They are mainly used in the Daily Selects section of the Shop, which is renewed each day. The first row is available to all players and doesn't contain any Super or High-End item, the second row is available to player of level 7 and above and doesn't contain any High-End item, the third row is available to players of level 12 and above and can contain any item. When an item’s skill level is maxed out, the item is replaced with a Level-boost ticket of the same rarity and price. The first time an item’s skill level is maxed out, Level-boost tickets of all rarities and types become available as well, having the price of the corresponding item type and rarity.

Since the Paris Tour, in addition to tickets, only a subset of non-tour-exclusive items can be found as Daily Selects:

Courses
In addition to the courses listed below, many alternate courses are also featured in the game; courses can have an "R" (Reverse) and/or "T" (Trick) variant. Courses marked with "R" are driven in backwards orientation; the track will have alterations if necessary to make this possible. Courses marked with "T" feature many additional ramps and trickable obstacles, and are otherwise the same.

Tours
Each tour consists of a series of cups, with each cup containing three courses and a bonus challenge. The featured character of the cup has the preference for every track in it increased by one tier. The following tables list the courses that make an appearance in each tour; "N" indicates a normal course, "R" a reversed course, "T" a trick course, and "R/T" a reversed trick course. Tracks in gray debuted during the respective tour. Click on a cup's icon to access the article of that cup.

Drivers



 * For the tables to convert the Level shown here in the actual statistics used by the game, see Mario Kart Tour in-game statistics.

There are currently 49 playable characters (50 if including Gold Mario, who appears exclusively in the Coin Rush mode) in Mario Kart Tour. Upon launching the game for the first time, players start with either Toad, Toadette, or Peachette. After the tutorial they are granted a free pipe pull which grants either Peach or Bowser. Unlike other Mario Kart games, there are no weight classes between characters, but they are sorted by their rarity of unlocking them, via opening up randomized green pipes with rubies. There are three tiers of rarity: Normal, Super, and High-End. While the Normal characters are easier to unlock, rarer characters have a greater amount of starting points and have more favored courses. Once players clear the tutorial, they are rewarded with a random Super-class character.

So far, the only changes in the main statistics that were found affect acceleration and weight, and depend on the kart size.

Below is a list of all drivers in the game grouped by rarity, displaying the special item, kart size, date of availability and favored tracks, as well as traits, for each driver. Traits, such as a mustache, extended tongue, or shell, may be shared between drivers. Some challenges in the game require the player to perform a certain action or a number of actions using any driver with a certain trait.

Tour-exclusive
These characters can/could only be obtained during certain tours.

Item Box items
Items function mostly the same as in previous installments in the series. As in Mario Kart: Double Dash!!, every character has their own special item that most other characters cannot get. A large change to the item system is introduced; depending on the character and course they're used on, players can get one to three items at once. In the case that a character gets three of the same item, they will activate the new Frenzy Mode, in which they immediately activate a Star and can use unlimited supplies of the respective item until the invincibility runs out. Any item can appear in Frenzy Mode, except for the Star, which is exclusive to certain bonus challenges.

The game introduces seven new items to the series, being the Double Bob-ombs, the Bubble, the Banana Barrels, the Mushroom Cannon, the Coin Box, the Dash Ring, and the Bob-omb Cannon, all of which are character-exclusive items.

Inventory items
These items are collected throughout the course of the game through various means, such as challenges, log-in bonuses, and Tour Gifts.

Hazards, obstacles and other elements
The following table lists elements that slow racers down, crash them, offer them a Jump Boost and/or simply give them points when interacted with in a certain way.

Cameo appearances
The following are only seen as background or intangible elements.

Bonus challenges
Bonus challenges are similar to the Missions mode from Mario Kart DS and the tournaments from Mario Kart Wii, and are found at the end of each cup. In contrast to races, these challenges offer 3 Grand stars instead of 5 when completed with the highest score needed. In most cases, the game will set the character for the challenge, giving them the Pipe Frame and the Super Glider, even if the player has not obtained them yet.

Challenges
Challenges are objectives the player can complete to earn various badges and rewards depending on the type, of which there are three: Standard Challenges, long-term challenges the player accomplishes throughout the course of the game; and Tour and Gold Challenges, challenges that last for the duration of the tour, the latter of which are exclusive to Gold Pass members. Completing Standard Challenges awards the player with rubies, while Tour and Gold Challenges award extra Grand Stars. Each challenge card holds nine challenges aligned in a 3×3 grid, and for every bingo the player acquires (i.e. any horizontal, vertical, or diagonal match), they earn 50 coins (100 coins for Standard Challenges). The player also receives a reward upon completing an entire challenge card.

The following are the Standard Challenges in the game. For the tour-specific challenges, see List of tours in Mario Kart Tour.

Apple Store demo
The special demo of Mario Kart Tour is made playable at Apple Store outlets. Unlike tours from the full version, only four cups are available and Coin Rush mode is inaccessible.

Reception
Initial impressions of the beta have been mixed. Journalists have praised the gameplay and graphics, but have criticized the free-to-play gacha elements of the game. Sam Machkovech of Ars Technica has compared the game's in-app purchases to Spiny Shells, blowing up the classic Mario Kart experience. He has suggested that "the developers pick a side: attach an annoying economy to a deeper control scheme and more legitimate online options, or make it cheaper and less obnoxious to watch Mario drive himself." Ethan Gach of Kotaku has also stated that the game is "a mostly faithful but stripped-down recreation of Mario Kart decked out with all the microtransactions and lottery mechanics mobile games are infamous for" and also lamenting the lack of a multiplayer mode. Steven Asarch of Newsweek has complained about the game's "freemium greed" and that it is "ruined by microtransactions".

As of October 11, 2019, Mario Kart Tour received mixed reviews, with a Metacritic Metascore of 59.

Pre-release and unused content
The beta version of the game saw multiple changes in the final game. The stamina element was removed, and the timers restricting access to certain cups can be sped up using quick tickets. Additionally, rubies were originally emeralds.
