Free open-world games for PC with no download

Sometimes you just want to play. Not to download a launcher, sign in to it, wait for a huge install and then update it. If you are on a work laptop, a shared family computer or a machine short of disk space, a game that runs in the browser is the easy answer. These are our picks of free open worlds you can play on a PC with nothing to download.

What counts here: the game starts on the web page. You may need an account for some, but there is no installer, no launcher and no browser extension. At the end we add cloud streaming, which also needs no install but works differently. Every pick is free to play.

1. AJ Cities: an estate on the edge of Ajegunle, Lagos

Our own game, so read this as a description. AJ Cities is a free, 18+ open-world game set in an invented estate on the edge of Ajegunle, Lagos. Open ajcities.com in Chrome, Edge, Firefox or Safari and you are standing on a Lagos street.

There are two ways to play. AJ’s story needs no sign-in: you are a man deported from London, broke on June 12 Street, raising the ₦2,500,000 the gate police want before they will open the gate, mostly by betting on street football in the bush. Or sign in and join other players live at the estate, in a world that is always day, always night or on real Lagos time. Optional tickets open more of the estate, but most guests who ask the police at the gate get in free.

It is a small, dense world rather than a vast one, and it is written for adults: crime, police corruption and a dodgy club owner. Keyboard and mouse controls are on the controls page.

2. Slow Roads: the endless drive

Slow Roads is a free browser driving game by a Scottish developer. The road never ends: it is generated as you go, through hills, valleys, forests and lakes, and you can change the season and time of day. There are no objectives and no way to fail, and you can even let the car drive itself. Reviewers found it runs on a low-power notebook with the graphics turned down. A paid offline version exists, but the web version is free.

3. Hordes.io: a 3D MMORPG in a tab

Hordes.io is a free 3D MMORPG that runs in the browser, built by a solo developer. You pick one of two factions and fight monsters and the other side in an open world, with classes, clans, crafting and trading. Reviewers note the visuals are simple and the grind can get repetitive, but there is nothing else quite like it: a real online RPG world without a download.

4. Minecraft Classic

For the game’s tenth anniversary in 2019, Mojang put Minecraft Classic, a recreation of the 2009 version, online free at classic.minecraft.net. You get 32 blocks, creative building only and the original bugs, and you can invite up to nine friends by sharing a link. It is a small, nostalgic world rather than the full modern game, but it is genuinely free and genuinely in the browser.

5. Torn: a city in text

Torn has run in browsers since 2004. It is free, and its own site says it needs no download or plugins. Its open world is a city you navigate through menus rather than streets: crimes, jobs, factions, trading and other players. Not 3D, but it runs on anything.

And one big game, streamed free: Fortnite

Cloud gaming runs a game on a remote server and streams it to your browser, so nothing is installed on your PC. Most cloud services need a subscription or a game you own. The notable exception is Fortnite, which Epic and Microsoft let you stream free through Xbox Cloud Gaming in a browser on a Windows PC, with just a free Microsoft account. Its LEGO Fortnite mode is an open-world survival game for up to eight players.

You will need a fast, steady connection, and a controller helps. Streaming also has a little delay between pressing a button and seeing it happen, which matters more in a shooter than in a calm build. For the bigger picture, read can you play big console open worlds in a browser.

At a glance

Getting the best out of browser games on a PC

• Use an up-to-date browser. 3D browser games rely on the browser’s graphics support, which improves with updates.
• Check hardware acceleration is on in your browser’s settings; without it, 3D games crawl.
• Close video tabs before you play. They compete for the same graphics chip.
• Plug in a laptop. On battery, many laptops slow themselves down.

Are browser games safe?

A real browser game runs on the page. If a site’s “Play” button downloads a file or asks you to install an extension, that is not a browser game, and it is worth closing the tab. Stick to the official sites of the games above. More in are browser games safe?
