Add your own game: HTML, folder, .zip or .play

Offline Games plays web mini games made of static files. Add one from the Files app:

• One HTML file: a game that fits in a single .html page, with its scripts, styles and images inside it or loaded from the web.
• A folder or .zip: a static web game with an HTML page that starts it (usually index.html) and the files it loads, such as scripts, images and sounds, linked with relative paths. If there are several HTML pages and no catalogue.json, Offline Games asks which page starts the game.
• A .play file: a PlayDrop game package, which is a .zip of the game's files renamed .play. Offline Games shares your own games as .play files, so friends can add them too.

• Once added, a game runs on your device, even offline. Anything it loads from the internet still needs a connection.
• Only static files run: server code such as PHP or Node does not.
• A game can have up to 10,000 files and 512 MB, with 100 MB per file.
• Games that use the PlayDrop SDK keep their progress through it; other games keep what they store in the browser on your device.

Offline Games fills in the name and description from the game's page title and description, or from its catalogue.json, and its picture from an image in the game's files when it finds one. Otherwise it uses the file name. You can change them before adding the game.

When you are signed in, you can also upload the game to your PlayDrop account as you add it: Private keeps a backup only you can open, Unlisted lets friends with the link play, and Public lists it for everyone. Unlisted and public games get a link to share. Uploads take up to 512 files, 50 MB per file and 200 MB per game. See Publishing for how PlayDrop publishes games.
