A repo filled with 300 offline games that can each run on a single file. This is a good option if you are having internet connectivity issues, or you're at some place with restricted internet.
Usage: Under the Code button, select Download ZIP. It may take a while to download. After, extract the zip by right clicking on it and selecting Extract All. Now you have the repo containing the games all in a folder. You can also clone the repository using git.
The downside of inlining everything is the file size. If you're running the files via a code editor, it's better to use single-file.html. It lets you fetch the files from the web or import your own.
