Mario Kart Tour race points system
Race points are earned in three ways: base points from the driver, kart and glider being used, bonus points earned by performing actions during the race, and position points, based on finishing position, driver level, and several other factors. Upon earning enough points in a given race, players can earn from that race up to 5 total Grand Stars, which are necessary to unlock further cups and tour gifts in the current tour.
The base points of the driver, kart and glider selected are added to the initial score of 0 before the race begins. Base points can range from 800 total points for base-level Normal items to 1600 points for maxed-out High-End items. Individual items' 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.
Many actions performed in-game give the player a number of bonus points. There are a wide variety of point-giving actions, ranging from hitting another player with an item to picking up a coin or simply running into a traffic cone. The base points are modified by many multipliers and bonuses before being added to the player's score. The full formula to calculate the bonus points of a single action, as given in the game's FAQ, is as follows:
The final result is rounded up to the nearest whole number. Each of these items is covered in detail in the following sections.
Action base points
Each action in a race has a default number of points associated with it, called the base points of the action.
These actions are performed with specific items or in Frenzy mode.
These actions are performed by interacting with hazards or other elements that appear on one or a few tracks.
These actions can be performed on most or all tracks.
A few tours have introduced elements to every track that give points with a special message when interacted with. These actions have also had one or more associated spotlight drivers, to whom the action awards far more base points.
Interim rank points
Points are earned when crossing a Finish Line to begin lap 2 or enter another segment of the track. The points earned depend on the player's position and the engine class used. 200cc is considered identical to 150cc here, as it is across the rest of the points calculation. The action triggered also allows one extra second on top of your normal combo time before the next action.
Kart bonus-points multiplier
The base points of the action are first multiplied by the bonus-points multiplier of the kart, determined in two parts. The first part is a simple multiplier dependent on the kart's tier on the course: top-tier karts receive a x2 bonus, middle tier karts receive x1.5, while bottom-tier karts receive the default x1. A further multiplier is applied based on kart rarity and level, as shown in the below table. The multipliers stack, so x1.1 on top of x2 becomes x2.2.
Special skill boost
Every driver, kart, and glider has a special skill that separates it from the others. For drivers, the special skill is a unique item, such as the Boomerang Flower or Coin Box; these are covered in the "Item Actions" section above. For karts, the special skill is a boost to a general action, such as Mini-Turbo or Jump Boost, which awards more points and a bigger speed boost when performed. For gliders, the special skill is a boost to a general item, such as the Banana or Super Horn, which increases the chance of rolling that item and awards more points for landing a hit (or simply using the item, in the case of Mushrooms). The point bonus for kart and glider actions is added directly to the score after the multipliers, and depends only on the item's rarity; it is not affected by level or course tier.
Skills with missing points values mean there are no gliders of the given rarity with that skill, as of the Ice Tour. Note that the Coin and Mushroom boosts only apply to rolled items, and not those picked up from the track.
when performing multiple actions within a short period of time, you receive a combo bonus for each successive action. The length of time allowed depends on the level and course tier of the glider used, though time limits are suspended while gliding, riding in a Bubble or in Frenzy mode. The combo points themselves, however, only depend on the glider's tier on the course. The first action in a combo is awarded a combo bonus of 0, and successive actions each get an increase depending on glider tier:
There is also a cap to the combo bonus that depending on engine class:
This leads us to the following table for max combo bonus:
Perhaps the most confusing part of the points system, the bonus-points boost is a single points bonus that is added to every single action performed, up to and including the 200th. The driver, kart, and glider are each considered separately in calculating the bonus. If an item in use is top-tier for the course and at level 2 or above, its bonus points boost is determined by the following formula:
where 200cc is still treated as 150cc. As an example, say you have a level 3 Bowser, maxed out at 675 base points, and you use him for a 200cc race at Bowser's Castle 1T, one of his top-tier courses. Then the bonus-points boost would be:
Thus, you would earn 6.75 extra points per action. Let's say you also use the Bull's-Eye Banzai at level 2, but with minimum 200 base points:
The kart would thus be worth a meager 1 point per action. Finally, on the opposite end of the spectrum, say you use a level 6 Swooper, with max 400 base points:
Your total bonus-points boost for this setup would be 17.75 points per action. You can earn up to 40 bonus points per action in this manner if you use a maxed-out level 6 High-End driver, kart, and glider. The bonus-points boost is reapplied at the end of the race, effectively doubling its total; more on that in the final section.
At the very end of the race, points are given based on the player's level and finishing position, along with another helping of the bonus-points boost. Nintendo gives the position points formula as:
Base position points
The base points you earn for finishing 1st are called base position points. These range from 2000 to 4980, depending on player level and engine class:
When finishing in a rank other than 1st, a simple multiplier is applied to the base position points, with diminishing returns for lower ranks:
The driver, kart, and glider each apply their bonus-points boost again at the end of the race. The formula is largely unchanged, but an extra step is added:
Since the same boost is applied to each action during the race, this will be roughly equal to the bonus-points boost earned throughout the race, although it tends to be slightly less due to the favorable rounding on individual actions' boosts.
