What is wasm arcade?

WASM Arcade (wasmarcade.com) is a free browser game library built on one idea: compile real game engines to WebAssembly so they run at near-native speed inside a browser tab, with no install, no plugin and no account. According to its official about page, it runs Grand Theft Auto: Vice City and Grand Theft Auto III on the open-source reVC and re3 engines, The Simpsons: Hit & Run as a native WebAssembly port, Minecraft 1.8.8 through EaglercraftX, 227 arcade boards (Capcom CPS1/CPS2/CPS3, Neo Geo and more) through the EmulatorJS build of FinalBurn Neo, and 850 curated Flash games through the Ruffle emulator. That is more than 1,000 playable titles in total.

It is not streaming. The site states that nothing is rendered on a remote data center: your own browser and graphics card draw every frame, game data streams in the background as it is needed, and your browser caches it so only the first visit waits. Saves are written to your browser's local storage, never uploaded to a server, and each game page has a Save Manager that can export a save to a file as a backup.

The project is candid about ownership and money. It says the games belong to their original studios and publishers, that it is not affiliated with any of them, and that a rights holder can request removal under the copyright and takedown policy. Operation is funded by advertising: pressing Play opens a sponsor page from an advertising partner in a new tab, which you can close. There are no accounts and no in-game purchases.

This page is an independent factual guide. It does not host, embed, copy or proxy any game, and it does not claim you can play anything here — to play, you use the official site linked above.

How to play games on WASM Arcade

1. Open the official site, wasmarcade.com, in a current desktop Chrome, Edge or Firefox (Safari 15.4+ supports WebAssembly and WebGL 2.0, but the site recommends current Chrome, Edge and Firefox for best results).
2. Pick a title from the library — GTA Vice City, GTA III, The Simpsons: Hit & Run, Minecraft 1.8.8, the arcade boards section, or the Flash arcade.
3. Press Play. A sponsor page from an advertising partner opens in a new tab; you can close it and the game starts either way. Game data loads in the background as needed and is cached by your browser, so the first visit is the slow one.
4. Play with keyboard and mouse or a gamepad. The site notes the GTA games also have touch controls on phones and tablets, and that The Simpsons: Hit & Run is a threaded engine that needs a browser running in an isolated context (such as a regular tab, not forced into a restrictive mode).
5. Your progress stays in your browser's local storage between visits. Use the Save Manager on each game page to export a save file if you want a backup or to move between browsers.

What runs under the hood

• GTA Vice City and GTA III run on reVC and re3, open-source reimplementations of the original engines, compiled from C++ with Emscripten.
• The Simpsons: Hit & Run is a native WebAssembly port, compiled from C++ with Emscripten using multithreading.
• Minecraft 1.8.8 runs through EaglercraftX, a browser port of the Java edition built with TeaVM and WebAssembly GC.
• The 227 arcade games run on the EmulatorJS build of FinalBurn Neo, emulating Capcom CPS1/CPS2/CPS3, Neo Geo and other boards.
• The 850 Flash games run on Ruffle, an open-source Flash Player emulator written in Rust and compiled to WebAssembly with wasm-bindgen; the site says they were curated from more than 1,300 candidates and each was tested under Ruffle before inclusion.

Safety, legality and ads — read before you play

• Sandboxing: WebAssembly code runs inside the browser's standard security sandbox, with no more access to your computer than any other web page, according to the site's about page.
• Ownership: the games belong to their original studios and publishers. WASM Arcade says it is not affiliated with any of them, claims no ownership, and will remove a game on a rights-holder request — see its copyright and takedown policy at wasmarcade.com/copyright.
• Ads: the library is funded by advertising. One sponsor tab opens when you press Play; the site says ads are kept away from the game while you play and its privacy policy names every advertising partner.
• No account: the site never asks for a name, email or password to play.
• Best experience: use a current desktop browser, close other heavy tabs, and expect the first load of a large game to take a while as assets stream and cache.
