GameShare’s biggest feature isn’t the sharing — it’s what’s missing from the list. Nintendo’s own launch showcase title, Mario Kart World, doesn’t support it [7]. Everything else worth knowing follows from that: which of the 73 compatible games [5] actually work, whether it costs anything, and how to stop the stuttery mess it becomes over a bad connection.
At its core, GameShare streams a game running on one Switch 2 to up to three other consoles in real time [2] — the same idea as a game-streaming service, not a copy transferred to the guest’s system. That distinction explains almost every limitation in this guide: the video-compression hit, the session-only access, and why an original Switch can join but never host [1].
Skip the theory if you just want it working. On the host Switch 2:
- Launch a GameShare-compatible game — look for the GameShare icon on its tile.
- Open the in-game or system menu and select GameShare.
- Choose Local Play. No internet or Nintendo Switch Online membership is needed for this [1].
- On the guest console (Switch 2 or original Switch), select the GameShare icon that appears on the Home Menu and accept the invite.
- Stay within 2–3 meters of each other with a clear line of sight — walls, metal, and glass all degrade the wireless signal [3].
- Play. When the host closes the game, the session ends and the guest loses access until it’s shared again [2].
GameShare doesn’t send a copy of the game to your friend’s console — it streams video and takes back their controller inputs from a game running entirely on your Switch 2 [1][2]. That’s why image quality drops during a session: Nintendo explicitly trades resolution for responsiveness so the stream stays playable [2].
It’s a real departure from how Nintendo used to solve this problem. On the DS and 3DS, Download Play sent a small compatible program to guest systems so each device ran its own local copy of a stripped-down game — no host hardware doing double duty, no compression [7]. GameShare instead asks one Switch 2 to render and stream the full game to up to three other systems simultaneously [2], which is why performance depends heavily on your Wi-Fi environment rather than just the game’s own requirements.
Only a Switch 2 can host a session. Any Switch 2 or original Switch can join as a guest, but an original Switch can only join locally — it can’t receive a GameShare stream over the internet through GameChat [1][2].
Local GameShare is free and needs no subscription; online GameShare runs through GameChat and requires a paid Nintendo Switch Online membership [1][6].
| Sharing Method | Who Can Join | Cost | Voice/Video Chat | Max Participants |
|---|---|---|---|---|
| Local (same room) | Switch 2 or original Switch nearby | Free — no NSO required [1] | Not built in | 4 systems total (host + 3 guests) [2] |
| Online (via GameChat) | Switch 2 only | Requires NSO: $19.99/yr individual, or roughly $10/person/yr on an 8-person Expansion Pack Family plan [8] | Voice + optional video | 4 systems total (host + 3 guests) [2] |
The practical takeaway: if everyone can be in the same room, GameShare costs nothing; the moment you want to play with someone over the internet, it’s gated behind the same Nintendo Switch Online membership every other online feature needs [1][8].

Which of the 73 Compatible Games You Can Try
As of September 5, 2026, 73 Nintendo Switch 2 games support GameShare — 66 that work both locally and through GameChat, and 7 that are local-only [5].
| Category | Examples |
|---|---|
| Local-only (7 titles) | Brotato, Donkey Kong Country Returns HD, Marvel Cosmic Invasion, NBA 2K26, Split Fiction, Suika Game Planet, Super Mario Party Jamboree – Nintendo Switch 2 Edition + Jamboree TV [5] |
| Local + Online, 66 titles (examples) | Mario Tennis Fever, Kirby Air Riders, Stardew Valley (Switch 2 Edition), Overcooked 2 (Switch 2 Edition), WWE 2K25, EA Sports FC 26 [4][5] |
Support is opt-in per game and arrives through free software updates, not automatically [1][6] — a game you own today could gain GameShare compatibility next month without you doing anything on your end. Check the list before assuming a title is permanently excluded.
Verified against Nintendo’s official GameShare pages and a third-party compatibility tracker as of September 2026. The list grows with each Nintendo software update, so treat the 73-game count as a floor, not a ceiling.
| If you are… | Do this |
|---|---|
| New to Switch 2, deciding whether to buy a game | Use local GameShare to trial a compatible title on a friend’s copy before spending money — but check the compatibility list first, since most brand-new releases (including Mario Kart World) aren’t on it [1][7]. |
| A household with multiple Switch/Switch 2 consoles, e.g. kids sharing games | Stick to free local GameShare if everyone’s under one roof — it covers up to four consoles per session with no subscription cost [2]. Our co-op games for parents and kids guide covers titles worth sharing this way. |
| Friends who live apart, or anyone wanting online co-op | Only the paid GameChat route works for you. Budget for NSO — Individual at $19.99/yr, or the roughly $10/person Family Expansion Pack if three or more people share — since local-only GameShare is useless without physical proximity [1][8]. |
| A completionist tracking every compatible title | Recheck the official list periodically. Any of the 7 local-only titles could gain online support in a future patch, and Nintendo doesn’t publish a roadmap for which games are next [1][5]. |
Why Mario Kart World Isn’t on the List
Nintendo’s own system-seller is the most conspicuous absence from the GameShare roster: Mario Kart World does not support it, on the one launch title Nintendo had every reason to show the feature off with [7].
Nintendo hasn’t stated a reason publicly. Some outlets have floated the obvious commercial explanation — a genre where most players want their own copy anyway, and free-sharing the console’s best-selling game would cut into a title Nintendo doesn’t need help moving [6]. That’s informed speculation, not a confirmed Nintendo statement, so treat it as commentary rather than fact.
What makes the omission sting is precedent: both Mario Kart DS and Mario Kart 7 supported Download Play, letting one cartridge cover multiplayer for a whole group of DS and 3DS owners without everyone buying a copy [7]. GameShare, mechanically, could do the same job for Mario Kart World — stream the race host’s session to three friends’ consoles — and Nintendo chose not to enable it. If you want to play Mario Kart World with friends who don’t own it, local wireless multiplayer with each player owning a copy is still the only supported route.
Fixing Lag, Drops, and Connection Problems
Most GameShare connection problems trace back to physical distance for local sessions or network congestion for online ones, and Nintendo’s own fixes address exactly those two causes [3].
Local wireless: restart both consoles (hold the Power button for at least 3 seconds), keep them 2–3 meters apart with a clear line of sight, remove metal or glass objects between them, and turn off other nearby Bluetooth or Wi-Fi devices [3].
Online via GameChat: switch from Wi-Fi to a wired connection when your console is in TV Mode, check your router’s NAT Type, turn off your camera and hide other players’ shared screens to cut bandwidth use, or pick a GameChat layout that gives less screen space to shared gameplay [3]. Our Switch 2 best settings guide covers broader performance tuning if GameShare specifically isn’t the only thing running rough.
Check Nintendo’s network status page before troubleshooting your own setup — a server-side outage looks identical to a local connection problem [3].
Frequently Asked Questions
Only if you use it online. Local GameShare between consoles in the same room is completely free with no Nintendo Switch Online membership needed; the moment you share with someone over the internet through GameChat, you need a paid NSO membership, because GameChat itself sits behind that subscription [1][8].
No — hosting requires a Switch 2. An original Switch can only ever be a guest, and only locally, never through GameChat online [1][2]. If neither player owns a Switch 2, GameShare isn’t an option at all — that’s the one hard requirement in the whole system.
Generally no. Guest progress in a shared session doesn’t automatically carry over into a purchased copy — some titles do write limited save data to the guest console for later use if that player buys the game, but that’s a per-game exception, not the default behavior [2]. Don’t assume a friend’s playtime during your session banks toward anything unless the specific game says so.
Almost certainly, but on Nintendo’s own schedule, not a published one. Every game added so far arrived through a free software update after launch, not at release [1][6], and the list grew from roughly a few dozen titles [4] to 73 [5] within months — so checking back periodically is more useful than assuming today’s list is final.
