Slime Rancher — Play Online Free in Browser

About Slime Rancher

A cheerful first-person farming adventure: vacuum up bouncy slimes on a distant planet and sell their plorts.

Slime Rancher (2017) by Monomi Park follows Beatrix LeBeau, a young rancher who moves to the Far, Far Range. With a vacuum pack you suck up slimes, feed them fruit, veggies or meat, and collect the plorts they produce to sell on a fluctuating market.

Mixing slime types creates largos with new needs, while Tarr outbreaks punish careless ranching. You expand the ranch, explore new zones and uncover the story through notes. The link is an unofficial web build; play with WASD, the mouse and both mouse buttons.

How to play Slime Rancher in your browser

Press Play in browser — the game opens on gn-math.dev in a new tab.
Wait while the game files load. The first start can take from a few seconds to a few minutes depending on your connection; later starts are faster because the browser caches the files.
Click inside the game window so it captures the keyboard and mouse, then switch to fullscreen (F11 or the host's fullscreen button).
Open the in-game settings to adjust controls, graphics and sound. Progress is normally kept in your browser storage, so don't clear site data if you want to keep your saves.

What to expect from the browser version

The browser version of Slime Rancher is an independent web project — a port, recompilation or fan remake — hosted on gn-math.dev. It is not an official release from Monomi Park, and MePlayable does not host any game files: we describe the game and link to the project.

Because the game runs inside a browser tab, some features of the 2017 original may be missing or work differently: online modes, cutscenes, saves, mods and graphics options depend on the build. If something doesn't work, check the host's own notes.

Requirements

A modern desktop browser — Chrome, Edge, Firefox, Opera or Safari 16+ — with WebAssembly and WebGL enabled, at least 4 GB of RAM and a stable connection for the first load. Hardware acceleration should be switched on in the browser settings.

If Slime Rancher doesn't start

Black screen or endless loading — update the browser, enable hardware acceleration and reload the page with Ctrl+F5.
No sound — click inside the game window: browsers only allow audio after you interact with the page.
Lag or low FPS — close other heavy tabs and programs, then lower the resolution or graphics settings in the game.
The site doesn't open — the host may be temporarily down or blocked in your region. Try again later or use another project link on this page.

Slime Rancher: frequently asked questions

Which site hosts the browser version of Slime Rancher?

The playable web version of Slime Rancher runs on gn-math.dev. MePlayable doesn't host game files: we check the link, explain controls and point you to the project page.

Can I play Slime Rancher online for free?

Yes. The browser version on gn-math.dev is free to open, and MePlayable doesn't charge anything — we simply link to the project.

Do I need to download Slime Rancher?

No. Slime Rancher runs directly in a browser tab using WebAssembly and WebGL, so there is no installer and nothing to download. The browser only caches files to make the next launch faster.

Can I play Slime Rancher on a phone?

The browser version is made for computers and expects a keyboard and mouse or a gamepad. Some phones and tablets can open it, but performance and touch controls are not guaranteed.

Can I play Slime Rancher with friends?

Is this the official Slime Rancher?

No. The original Slime Rancher was developed by Monomi Park and released in 2017. The browser version is a third-party project, and all rights to the game belong to their owners.

Will my progress be saved?

Usually yes: saves are stored in your browser's local storage on this device. They are lost if you clear browser data, use private mode or switch to another browser or device.
