About Super Mario 63
A famous flash fan game inspired by Super Mario 64 and Sunshine, with a level designer.
Super Mario 63 (2009) by Runouw is a fan-made 2D platformer that borrows ideas from Super Mario 64 and Super Mario Sunshine — Power Stars, F.L.U.D.D. and Shine Sprites — and adds a level designer.
It is a non-commercial fan project. The browser build is an unofficial web port: loading can take a while, and a keyboard and mouse are recommended.

How to play Super Mario 63 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.

| Action | Key |

| Pause | Esc |
| Gamepad | Recommended — connect it before starting |
What to expect from the browser version
The browser version of Super Mario 63 is an independent web project — a port, recompilation or fan remake — hosted on gn-math.dev. It is not an official release from Fan project, and MePlayable does not host any game files: we describe the game and link to the project.
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 Super Mario 63 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.
