Mario Kart World player count and multiplayer modes

Last checked: October 15, 2026

Mario Kart World supports up to 24 players in a single online race, up to 4 players in split-screen on one Nintendo Switch 2, and up to 8 players over local wireless, with no crossplay because the game runs only on Switch 2. Those limits apply across Grand Prix, Knockout Tour, VS Race and Battle, and they have not changed since the game launched on 5 June 2025. The figures below reflect Nintendo’s listed specifications and the live online service as of October 2026.

Player count by mode and connection type

The 24-racer grid is the defining number in this game. Mario Kart 8 Deluxe capped every race at 12, so Nintendo doubled the field for the Switch 2 release and built the course design, the item set and the new Knockout Tour mode around that larger grid. The table below lists the player ceilings you will actually hit in each way of playing, as listed on Nintendo’s product page and confirmed in the game’s menus as of October 2026.

Every race, in every mode other than Time Trials, fills the grid to 24 karts. When you race alone in Grand Prix, you are one of 24 and the other 23 are CPU. When four of you sit on one sofa in split-screen, you take 4 of the 24 slots and the game fills the other 20. The field size never shrinks to match the number of humans, which is a deliberate choice that keeps the wider tracks and the intermission routes from feeling empty.

How the 24-player field works

The jump from 12 to 24 racers changed the shape of the courses. Tracks are wider than the Mario Kart 8 Deluxe equivalents, starting grids are laid out in longer staggered rows, and item distribution is weighted so that a pack of 24 does not produce an unbroken chain of Blue Shells. If you are starting from 24th on the grid, the game hands you stronger recovery items than it would at 12th, and the frequency of the Bullet Bill and the new Kamek item reflects that.

You also move differently. Charge Jump lets you hop onto rails and grind along them, and wall riding lets you run along vertical surfaces for a few seconds to find alternate lines. Those systems matter more in a 24-player race than they would in a smaller field because they give you lines that the main pack is not using. A rail above the track or a wall on the outside of a corner can carry you past a dozen karts without a single item.

Grand Prix with 24 racers

Grand Prix in Mario Kart World runs in four-race cups, but the structure is different from any earlier entry. The first race of a cup is a traditional three-lap circuit. The second, third and fourth races start where the previous one ended and travel across the interconnected map to the next course, so you drive an intermission route before completing a lap or more of the destination track. The whole cup is a journey across the world rather than four isolated circuits.

The grid stays at 24 for every race in the cup, and the points table runs down to all 24 positions. Points accumulate across the four races, and the cup standings at the end decide the trophy. Playing locally, up to four of you can enter the same Grand Prix, each with a separate score tracked on the standings screen, while the other 20 slots are CPU drivers at the difficulty tied to your engine class.

Knockout Tour

Knockout Tour is the mode designed specifically for 24 players, and it is the one most people are asking about when they search for the player count. A Knockout Tour rally is a single continuous race across several courses, linked by the intermission routes on the world map, with no laps and no restarts. Checkpoints sit at the end of each section, and at each checkpoint the lowest-placed racers are eliminated on the spot.

Four racers are cut at each of five checkpoints, which means you need to hold at least 20th place through the first section, 16th through the second, and so on until only four karts remain for the run to the finish. Eight rallies are available in the mode, named after the item or feature at their heart: Golden Rally, Ice Rally, Moon Rally, Spiny Rally, Cherry Rally, Acorn Rally, Cloud Rally and Heart Rally. Each one strings together a different set of courses and intermission routes, and each takes several minutes longer than a standard three-lap race.

In split-screen, all four local players can enter the same Knockout Tour. If one of you is knocked out at the first checkpoint, that player’s screen switches to spectating the rest of the rally until it finishes, and the game shows the eliminated player’s final rank at the end. Online, the same elimination rules apply to the full 24-player lobby, and eliminated players can stay in the lobby to watch or back out to the room menu.

VS Race and Battle

VS Race is the custom-rules mode. You pick courses from a list rather than following the cup structure, set the engine class, choose between individual and team play, and decide how many races the session runs. Team play lets you split the field into groups, which works well in split-screen where two of you can take on the other two plus the CPU drivers that round the grid out to 24.

Battle returns with Balloon Battle and Coin Runners. The arenas are not standalone stadiums this time; they are enclosed sections of the racing courses, which means the rails, walls and jump points from the races carry over into the battles. Battle runs as team play and supports the same 24-player ceiling online, with up to four local players on one system and CPU filling the rest.

Split-screen on one Nintendo Switch 2

Four players on one console is the standard local setup, and it works in TV mode, tabletop mode and handheld mode. Each player needs their own controller, and the Joy-Con 2 pair that ships with the console counts as two controllers when you turn them sideways, so a new Switch 2 with no extra accessories supports two players out of the box. A second Joy-Con 2 pair or a pair of Pro Controllers takes you to four.

Performance drops as you add players. Nintendo confirmed the following targets, and they have held through the updates released up to October 2026.

Two-player split-screen at 60 fps is the detail worth knowing. Mario Kart 8 Deluxe on the original Switch also ran two players at 60 fps and three or four at 30 fps, so the Switch 2 did not change the pattern, but it does render the 24-kart grid and the larger open courses at that rate. In handheld mode the split-screen views share a 7.9-inch 1080p panel, which is fine for two players and cramped for four.

Free Roam also supports split-screen, so up to four of you can drive around the open map together, trigger P Switch missions and hunt for the collectible panels and peach medallions without entering a race. The world is shared on one screen division, and each player can head to a different region of the map independently.

Local wireless with multiple consoles

Local wireless connects up to eight players across nearby Switch 2 systems with no internet connection and no Nintendo Switch Online membership. Each console can bring one or two players into the session, so four systems with two players each hits the eight-player cap, as does eight systems with one player each. The remaining 16 slots on the grid are CPU racers, so the field is still 24 karts even in a full local wireless room.

Every participating system needs its own copy of Mario Kart World, either a physical game card or a digital licence. The game does not support GameShare, the Switch 2 feature that lets one copy be streamed to nearby consoles, so you cannot share a single copy across a room the way you can with some of Nintendo’s own Switch 2 titles. Local wireless gives you access to Grand Prix, Knockout Tour, VS Race, Battle and Free Roam, with the host system choosing the mode and rules.

Range is the usual Nintendo local wireless radius, which in practice means the same room or an adjacent one. The host sees the room list, players join from the Local Play option on the main menu, and the session ends if the host leaves. Two players sharing a system in a local wireless session use the same split-screen layout as a two-player local game, so both views on that console run at 60 fps.

Online play: requirements and lobby sizes

Online races require an active Nintendo Switch Online membership on the account that starts the session, a Nintendo Account linked to the console, and a broadband connection. The game’s online menu splits into Worldwide, Regional, Friends and Rooms, and all four can reach the 24-player ceiling. Nintendo does not disclose the minimum number of players before a worldwide match launches, but a lobby that is short of 24 humans fills the rest with CPU racers so the grid is always full.

Worldwide and Regional matchmaking alternates between standard races and Knockout Tour rallies depending on what the lobby votes for. Your rating, shown as VR points, rises and falls with your finishing positions in those random matches, and matchmaking groups you with players of a similar rating. Rooms and Friends sessions do not affect your rating, so they are where custom rules and casual sessions belong.

Update 1.1.2, released on 25 June 2025, adjusted the random matchmaking so that the “Random” vote draws from the three pre-selected intermission-style routes rather than always picking a traditional three-lap circuit, which reduced how often three-lap races come up. Before that patch, many players used the Random vote to avoid the intermission routes in worldwide play, and the change was Nintendo’s response. Rooms have always let the host pick specific courses, so that setting was never affected.

Two players online from one console

Two of you can go online from a single Switch 2 in split-screen. The first player’s account needs the Nintendo Switch Online membership, and the second player joins as a guest under that account, so you do not need two paid memberships for a two-player online session on one console. Both of you occupy slots in the 24-player lobby, your rating is tracked on the member’s account only, and the split-screen layout runs at the two-player 60 fps target.

Three and four players on one console cannot go online together. That limit matches Mario Kart 8 Deluxe and has not been lifted in any Mario Kart World update as of October 2026. If four of you want to race online as a group, you need at least two consoles, each with two players and its own membership-holding account.

GameChat and the Switch 2 camera

Mario Kart World was the launch showcase for GameChat, the Switch 2’s built-in voice and video chat. During an online session with friends, you can open GameChat with the C button on the controller, talk through the console’s microphone, and share video from a connected camera. The game places small video feeds from camera users above their karts on the track, which is the feature Nintendo led with in the April 2025 Mario Kart World Direct.

GameChat was free for all users until 31 March 2026. From 1 April 2026 it requires a Nintendo Switch Online membership, which you already need for online racing, so in practice nothing changed for anyone playing Mario Kart World online. GameChat supports up to 12 participants in a voice session and up to 4 video feeds at once, which means a full 24-player room cannot all be in one chat, but a group of friends spread across several consoles can.

Free Roam and the interconnected map

Free Roam is the mode that makes Mario Kart World different from every earlier Mario Kart, and its player count is easy to misunderstand. On one console, up to four players can explore the map together in split-screen. Online, you can roam with friends in a room, but Free Roam has no worldwide or regional matchmaking, so you will not meet random players driving around the map.

The map itself links every course by road, river and rail. Intermission routes that you race along in Grand Prix and Knockout Tour are open to drive at any time in Free Roam, and so are the areas between them that no race ever visits. P Switch missions scattered across the map set short challenges such as reaching a target before a timer runs out or collecting a line of blue coins, and hundreds of them exist across the world. Completing them unlocks stickers rather than courses or characters, so Free Roam is optional for anyone who only wants to race.

Dash Food, the item that changes your character’s costume when you drive through a food item on the roadside, is also tied to the world. Many costume unlocks require eating specific foods at specific locations, and in split-screen each player collects their own.

Courses and cups

The game ships with 30 distinct courses arranged into eight cups. Two courses, Crown City and Peach Stadium, appear in two cups each because the cup routes pass through them on the way to their finales. Classic tracks from earlier games return alongside the brand-new ones, reworked to sit inside the interconnected world rather than as isolated retro circuits.

Rainbow Road is the only course that sits outside the connected map. It is reached by a route that climbs away from the world, and it is the one course you cannot drive to in Free Roam. The eight Knockout Tour rallies route across the same 30 courses in different combinations, so between cups and rallies you will see every stretch of road in a race at some point.

Every course and every cup is available to all 24 racers at once. There are no smaller-grid variants for specific tracks, and the player caps in the first table apply identically to Mario Bros. Circuit and to Rainbow Road.

What Mario Kart World does not support

The game is exclusive to Nintendo Switch 2. It does not run on the original Switch, it does not have a cloud version, and there is no PC, PlayStation or Xbox release. That makes crossplay a non-question: there is no other platform to cross with. If you want to understand how cross-platform gaming works for multi-platform games, the concept simply does not apply here, and the same goes for cross-progression.

Other absences worth stating plainly as of October 2026:

• No GameShare, so each console in a local wireless session needs its own copy.
• No three- or four-player online from a single console; the online limit per system is two.
• No worldwide or regional Free Roam; open-map play with other humans is friends-only.
• No online Time Trials with live opponents; the mode uses ghost data from your friends and from Nintendo.
• No split-screen for more than four players, even on a large TV.

Price and subscription costs

Mario Kart World costs more than any earlier Mario Kart at launch, and online play adds the membership on top. The figures below are the standard list prices from the Nintendo eShop and Nintendo’s regional stores, as they stood in October 2026. Retail discounts vary and are not reflected here.

The standard Nintendo Switch Online tier is all that online racing needs. The Expansion Pack tier, priced at $49.99 per year individual in the US, adds retro game libraries and some DLC for other titles, and it does not unlock anything in Mario Kart World. The family membership covers eight Nintendo Accounts, which is the cheapest way to get several household members online from separate consoles for local wireless alternatives at a distance.

The game carries an ESRB rating of E for Everyone and a PEGI 3 rating in Europe, with no in-app purchases listed. It occupies approximately 23.4 GB of storage on the Switch 2’s 256 GB internal memory or on a microSD Express card, and the physical release is a full game card rather than a game-key card.

Controllers for local play

Every local player needs a controller, and the options matter for how many people a single console can host. The Joy-Con 2 controllers that come with every Switch 2 work as a pair for one player or as two sideways single controllers for two players. A second Joy-Con 2 pair, sold separately, brings that to four. The Switch 2 Pro Controller works for any slot, and original Switch Pro Controllers and Joy-Con controllers also pair with the Switch 2 for Mario Kart World, which helps if you are upgrading from an original Switch with a drawer full of accessories.

Steering with a single sideways Joy-Con 2 uses the stick and the SL and SR buttons on the rail. The Joy-Con 2 controllers have larger SL and SR buttons than the original Joy-Con, which was a direct response to complaints about sideways play on the first Switch, and it makes four-player local Mario Kart more comfortable than it used to be. Mouse mode, the Switch 2 feature where a Joy-Con 2 slides across a surface, is not used in this game.

FAQ

How many players can play Mario Kart World on one Switch 2?

Up to four players in split-screen on a single console, in TV, tabletop or handheld mode. Two players run at 60 fps and three or four players run at 30 fps. The other 20 slots on the 24-kart grid are filled by CPU racers.

How many players can race online in Mario Kart World?

Up to 24 players in a single online race or Knockout Tour rally, across worldwide, regional, friends and room sessions. A Nintendo Switch Online membership is required on the account that starts the session. As of October 2026 the cap is unchanged from launch.

Can two people play online together from the same console?

Yes. The second player joins as a guest under the first player’s account and both take slots in the online lobby. Three or four players from one console cannot go online together; that requires a second Switch 2.

Does Mario Kart World have crossplay with Switch 1, PC or PlayStation?

No. The game is a Nintendo Switch 2 exclusive with no release on any other platform, so there is nothing to cross-play with. Online matches are between Switch 2 owners only.

How many players does Knockout Tour support?

Knockout Tour always starts with 24 racers. Four are eliminated at each of five checkpoints, leaving four for the final section. Up to four local players or 24 online players can be human; CPU racers fill the rest.

Does local wireless need Nintendo Switch Online?

No. Local wireless connects up to eight players across nearby Switch 2 consoles without an internet connection or a membership. Each console needs its own copy of the game because GameShare is not supported.

Is GameChat free in Mario Kart World?

GameChat was free until 31 March 2026 and has required a Nintendo Switch Online membership since 1 April 2026. Since online racing already requires that membership, anyone playing Mario Kart World online can use GameChat at no additional cost.

Leo Brandt answers the questions that decide if friends can actually play together: does the game support crossplay, between which platforms, is co-op online, couch or both, and how many players a session holds. Crossplay in particular gets tested against the fine print, since "cross-platform" on a store page sometimes excludes cross-progression or leaves out one console entirely. He also tracks how long games take to beat, splitting main story, main plus side content and full completion into separate figures so readers can see which number applies to how they play. Player-reported times are labelled as such and kept apart from developer estimates.
