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 es 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.

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. Touch controls can be used in two configurations. The main setting has the driver jumping every time the screen is tapped, making drifting the main way to take turns, controlled by how the fingers slide on the screen. In the other configuration, the kart does not jump when tapping the screen, which results in it steering and auto-drifting as the fingers slide on the screen. This configuration does not allow the charge of an Ultra Mini-Turbo. 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, but a player will get 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. Grand Stars are used to unlock new cups and to receive Tour Gifts that appear in the form of gift boxes in the race selection screen. Experience points for drivers, karts and gliders are used to increase the points earned for a race by selecting a said driver, kart or glider. Coins are mainly used in the shop to purchase items. 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 increases 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.

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. 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.

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.

Original

 * Another New York-inspired course, featuring the and a tunnel road similar to the one found on Maka Wuhu from Mario Kart 7.
 * Paris Promenade, a course inspired by Paris, featuring the Eiffel Tower and the Arc de Triomphe as traversable landmarks.

Mario Kart DS (DS)

 * DK Pass

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 on gray debuted during the respective tour. Click on a cup's icon to access the article of that cup.

Drivers
There are currently 40 playable characters (41 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. 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, have a higher top speed, higher coin-earning rates, likelihood of picking up mid-race weapons and items, and have more favored courses. Once players clear the tutorial, they are rewarded with a random Super-class character.

The following lists the playable characters and their special item.

Future drivers
The following characters have been confirmed to be playable, though their rarities are unknown, as they are currently not available.
 * Shy Guy wearing a chef outfit

Other
The following karts were revealed in the game's trailers:
 * Prancer
 * Bullet Blaster with Monster tires
 * A macaron-themed vehicle

The following karts were present in the game's beta, but are currently unavailable:
 * Zucchini
 * Egg 1
 * Blue Seven
 * Bruiser
 * Bolt Buggy

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 become temporarily invincible 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 six new items to the series, being 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.

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.


 * Ready, Set, Rocket Start: "Pull off a Rocket Start!"
 * Ring Race: "Clear (number) rings."
 * Do Jump Boosts: "Do (number) Jump Boosts."
 * Big Reverse Race: "Aim for 1st!"
 * Goomba Takedown: "Hit (number) Goombas."
 * Glider Challenge: "Glide at least (distance)."
 * Steer Clear of Obstacles: "Don't crash!"
 * Vs. Mega (opponent): "Aim for 1st!"
 * Smash Small Dry Bones: "Smash (number) opponents."
 * Break Item Boxes: "Hit (number) Item Boxes."
 * Time Trial: "Go for your best time!"

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.

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.
