## Multiplayer Experiences in Discord
Activities are multiplayer games and social experiences embedded directly in Discord. They can be launched in channels, DMs, or from the App Launcher with no external window or separate download required.
Players can jump in together with friends already in a voice channel, making Activities a natural fit for party games, co-watching, collaborative tools, and more.
## Embedded App SDK for Activities
Under the hood, Activities are an iframe that communicates with Discord using the [Embedded App SDK](/developers/developer-tools/embedded-app-sdk). The SDK provides methods for interacting between your Activity and the Discord client.
