Open-world games to play with friends on mobile

Updated

Short answer

Roblox, Minecraft and Old School RuneScape are the three most people end up on: all of them put you and a friend in the same world on a phone, and all of them have done it for years. Genshin Impact is the better-looking option if you mostly play alone and want company occasionally, and Terraria is the only one here with no monetisation in it at all. The thing to check before you commit is not map size — it is whether your friends are in your session or just on your friends list.

"Open world" and "multiplayer" sit on the same store page constantly without meaning together what you would assume. A large mobile world with a friends list bolted to the side is still a single-player game: you see what your friends did, you send them something, you never stand next to them.

So the list below is ordered by one question — can you and a friend be in the same place at the same time — and then by how much work it takes to get there. Monetisation model and platforms are stated because they are stable. Prices, ratings and current content are not, so they are not.

In order

The list

  1. 1

    Roblox

    Best for the widest choice of shared worlds

    Not one open world but a platform of them, built by other players, where joining a friend is how anybody navigates the thing at all. If what you want is a city to mess about in with three people you know, some version of it already exists here. The trade is that quality is wildly uneven and you are the one sorting through it.

    Free to play. In-app purchases (in-game currency).

    Pros

    • + Joining a friend is the core mechanic, not a feature
    • + Enormous range of worlds, including city and roleplay ones
    • + One account across phone, PC and console

    Cons

    • − Quality varies enormously from world to world
    • − The in-game currency is pushed hard throughout
  2. 2

    Minecraft

    Best for building something together that lasts

    The default answer to this question for over a decade, and it still holds: a world you and your friends shape together and come back to. Worth knowing before you start that keeping a world running when nobody is in it generally means paying for hosting on top of the game itself.

    Paid once on mobile. Optional in-game marketplace.

    Pros

    • + A shared world that persists between sessions
    • + Plays with friends who are not on phones
    • + One purchase covers the game

    Cons

    • − Keeping a world online for friends usually costs extra
    • − Touch controls are workable rather than good
  3. 3

    Old School RuneScape

    Best for one persistent world and a player-run economy

    The closest thing on a phone to a world that carries on whether you are in it or not: thousands of other people, a market run by players rather than a shop, and a character that picks up on your desktop exactly where the phone left it. It looks its age on purpose, which is also why it runs on almost anything.

    Free to play, with an optional paid membership.

    Pros

    • + One shared world, no lobby codes or invites
    • + The same account on the phone and the desktop
    • + Economy is driven by players trading, not by a store

    Cons

    • − Most of the game sits behind the membership
    • − Pacing and presentation are an acquired taste
  4. 4

    Genshin Impact

    Best-looking open world on a phone

    The most impressive thing here to look at, and the one where friends are the side dish rather than the meal. Co-op is a mode you drop into for a while; the story around it is single-player. That is fine if what you want is a big world to explore alone with company available when you feel like it.

    Free to play. In-app purchases (gacha).

    Pros

    • + Genuinely large hand-built world
    • + Plays across phone, PC and PlayStation

    Cons

    • − Co-op is a side mode, not how the game is designed to be played
    • − Gacha monetisation is the entire business model
  5. 5

    Terraria

    Best for playing together with nothing to buy

    A 2D sandbox with a very deep crafting and combat progression, ported whole rather than trimmed down for phones, and the only entry here that will never ask you for money again. Playing together works, but getting a session up takes more than tapping a friend's name, which is the price of that.

    One-time purchase. No in-app purchases.

    Pros

    • + Nothing to buy after the game itself
    • + Huge progression with no paywalls in it

    Cons

    • − Setting up a session with friends is the fiddliest here
    • − Touch controls take adjustment

Where Craze City fits — not out yet

Craze City is built on the distinction this list keeps making. One shared city, no server list to scroll and no lobby codes to paste — you tap play and your friends are already there — and your money, house, garage and reputation live on the account rather than on the handset. It is free with no in-app purchases of any kind, and it needs a connection, because the city is genuinely shared rather than a solo world with a friends list attached. It is also not out: soft launch is planned for 2026, so it belongs on a wishlist rather than in the ranking above. Everything on that list you can play today.

Before you buy

How to check you will actually be in the same world

Store listings describe three very different things in nearly the same words. "Co-op" usually means a session you both join for a while and then leave. "Online multiplayer" can mean a shared world or a matchmade lobby. A friends list, gifting and leaderboards mean the game is single-player and being sociable about it. If the listing does not say you are in the same world, assume you are not.

Then check where progress lives. If your character, money and possessions sit on an account, you can change phone and play alongside friends who are not on one. If they sit on the device, a new handset starts you over, and playing with someone on a desktop or a console is usually out.

Last, check whether the game asks you to pick a server or a region. A server list is the most common way two people who bought the same game end up unable to play together — one of you chose the wrong one at signup, and the fix is normally starting again. Games that never ask the question cannot get it wrong.

On accuracy. This page describes monetisation models and platforms, which change rarely. It deliberately avoids quoting prices, star ratings and store availability, because those change often and a stale number is worse than none. Check the store listing before buying — it is the only source that is right today.
