== Gameplay ==
Nickelodeon Kart Racers 4 is a party kart racer with racecourses based on locales from various Nickelodeon animated series. Each race consists of twelve racers, who are able to hinder their opponents with a variety of different items that can be earned by driving through orange Splat Bubbles. Depending on their placement at the end, racers earn a different amount of points (12 for first place, 11 for second, 10 for third, and so on) that determines their overall placement.
When racing on the ground racers can drive over puddles of slime to fill their Slime Meter, which can be used to activate their Chief Skill. Collecting Slime Tokens also fills up the Slime Meter a short amount, as does performing Slime Stunts after going off ramps.
No matter if racing on the ground or on water, the player can also drift around corners, tightening their turns, and, when they go off jumps, perform tricks. Performing tricks and drifting can also fill up the racer's Slime Meter, and doing these enough may also cause the racer to have slime dumped on them, completely filling up their Slime Meter.
=== Races ===
There are several different types of races that players can compete in. Aside from the basic race type there are Elimination Races, Checkpoint Races, and Battle Races. When playing on Hard or Expert difficulty in Championship Mode, these different race types will often take effect after the first lap of certain races.
* Races are the most basic game mode. Ten racers must complete three laps of a course, with the amount of points earned at the end of a race depending on their placement at the end of the race.
* Elimination Races are the most common type of race variant that appears in Championship Mode. In an Elimination Race, the racer in last place will be eliminated after a certain amount of time has passed, and the game ends when only one racer remains. The amount of time before a character is eliminated begins with 30 seconds and depletes as racers are eliminated.
* Checkpoint Races are a slight variant of the normal race mode, which also combines some elements of the Elimination Race mode. In a Checkpoint Race, arrow signs are spawned around the course, and racers have to pass by the sign on the side it points towards. If they do not pass a checkpoint on the correct side, they will earn an X on the top-right corner of the screen. Failing to correctly pass a checkpoint three times will have the racer eliminated. Unlike in Elimination Races, the race will end once all remaining racers complete three laps.
* Battle Races are a special type of race in which players are forced to make use of the game's items. While the aim of a Battle Race is to complete three laps of the course, all racers have a Health Gauge that depletes as they take damage. Once a racer's Health Gauge has been completely emptied - which takes five hits - they are eliminated from the race.
All race types can also be played in Team Mode, with all racers being separated into two teams of five - Team Green and Team Orange. In Team Mode, racers on the same team can not harm each other, and, in normal races, all of the points they earn in a race go towards their team's total score.
== Characters ==
Nickelodeon Kart Racers 4: Slime Superstars brings back the crew system that was first introduced in Nickelodeon Kart Racers 2: Grand Prix. Through this party system, the player chooses a playable driver character, a chief, and two crewmates, with the latter three characters acting as "support" characters and granting the player different abilities over the course of the race.
Unlike previous games, in which the crew members appeared using only 2D artwork, all characters are now represented in full with 3D models. This is partly due to the fact that the game features collectible Figurines that make use of all of these models and feature short descriptions relating to the character and how they appear in their show. The Figurines of the playable cast also act as the game's sound test, as the player can listen to their voice clips once their corresponding Figurine has been collected. Figurines are unlocked simply by playing the game, with one Figurine being gifted at random when a set of races has been won.

There are a total of 80 playable drivers in the game; 39 of which were not playable in previous titles. While most of the cast is available to play as from the onset, 35 characters on the roster must be unlocked through the Grand Prix or Challenge modes. All but five drivers return from the previous instalments of the Nickelodeon Kart Racers series, with the cut characters being: , Purple Reptar, Kamper SpongeBob, Kamper Patrick, and Eastman and Laird Raphael.

As in Nickelodeon Kart Racers and Nickelodeon Kart Racers 2, the Rugrats characters also go back to using their designs from the original animated series as opposed to their updated ones from the computer-animated reboot. The characters also continue to use their designs from the 1987 animated series. 
The player can customize their stats by switching out their kart's engine, exhaust pipes, and wheels. There are also a number of paintjobs available to the player, which allow them to replace the default appearance of the character's kart with a variety of different designs. Additionally, as with in Nickelodeon Kart Racers 3, every character is capable of using any vehicle, thus the statistics displayed refer to their default kart body.

== Trivia ==
* With the and franchises getting represented, Nickelodeon Kart Racers 4 marks the first time any show is represented in a Nickelodeon crossover game. This excludes , which was previously represented in the 2013 fighting game Super Brawl 3: Good vs. Evil prior to its retooling for younger audiences beginning with Season 8 in 2019.
* As with all previous Nickelodeon Kart Racers titles, Teenage Mutant Ninja Turtles is the show with the most amount of playable representatives with seven.
** If one counted all of SpongeBob SquarePants, The Patrick Star Show, and Kamp Koral as a single franchise, it would have the most amount of representatives with nine. Under this logic, Nickelodeon Kart Racers 4 would be the first game in the series in which Teenage Mutant Ninja Turtles does not have more playable characters than every other series.
* Nickelodeon Kart Racers 4 brings back every playable character from Nickelodeon Kart Racers, making that the only previous game without a single cut.
** The game also brings back all pre-existing characters from Nicktoons Nitro. The only character from that game who does not return as a playable character is Lord Nitro, who was created to act as the main antagonist of that game's story mode.
** Eliza Thornberry is the only playable character who is not playable in Nickelodeon Grand Prix 4 but was playable in Nicktoons Racing, the first Nickelodeon crossover kart racing game.
*** Consequently, this marks the first time that Darwin, Norbert Beaver, Daggett Beaver, and Ickis have all appeared in a kart racing title since Nicktoons Racing.
*** In a similar vein, Professor Calamitous is the only character who is playable in Nicktoons Winners Cup Racing but not Nickelodeon Grand Prix 4. This also marks the only other time Vlad Plasmius has been playable in a kart racer since that game, as well.
* Though multiple characters were removed from the roster in the transition from Nickelodeon Kart Racers 3, JoJo Siwa is notably the only one of the cut characters to:
** have been playable in Nickelodeon Kart Racers 2;
** be a unique character, and not an alternate version of a character who was already playable;
** and have been the sole representative of a series. The JoJo and BowBow Show Show is thus the only series to have been completely cut from Nickelodeon Kart Racers 3.
* is the only series that received playable representation in the previous titles that both reappears in Nickelodeon Kart Racers 4 yet continues to have only a single playable representative.
** This excludes The Legend of Korra for a variety of reasons. The Legend of Korra can be counted as part of the greater Avatar franchise, and its predecessor does have several playable representatives. Additionally, though their designs in Nickelodeon Kart Racers 4 are based upon how they appear in the original animated series, all of the playable Avatar: The Last Airbender characters make appearances in The Legend of Korra as well.
** Despite the fact that they race in a single vehicle, it is possible to argue that this is not true: CatDog can be, and often is, considered both a single entity ("CatDog") and two separate entities ("Cat" and "Dog").
* and receive representation in Nickelodeon Kart Racers 4, the first time since the 2010 web game Super Brawl 2 in which the appear together. With the addition of Adventures in Wonder Park representation, Nickelodeon Kart Racers 4 features representatives from all three Nickelodeon animated feature films that have also received television adaptions: , Barnyard, and .
