How to play downloaded HTML5 games

Download the game .zip and unpack it into a directory <gamedir>.

Run game from a local webserver (preferred solution)

Regardless of browser you can always run the game by utilizing a local webserver, e.g. if python 2.x or 3.x is available:

1. Open a console
2. cd <gamedir>
3. python -m SimpleHTTPServer 8080 (for python 2.x) or python -m http.server 8080 (for python 3.x)
4. In the browser type: http://localhost:8080

You can use a different port as in the example.

Run game just by opening the index.html in browser

Some fragmentation on this route now:

Chrome and derivatives, e.g. Opera or Chromium: Start the browser with option --allow-file-access-from-files.

Firefox: Set privacy.file_unique_origin in about:config to false.

Waterfox: Just open the index.html.

Pale Moon: Treats local files as cross origin and there seems no option for an override (=does not work).

MS Edge: Experience depends on Edge version. Edge (Pre-Chrome) on Windows 10: In explorer right-click index.html, then choose edge browser to open it. Edge (Chrome-based) on Mac: Open Shell. "cd <gamedir>". Then "/Applications/Microsoft Edge.app/Contents/MacOS/Microsoft\ Edge --allow-file-access-from-files index.html". On my old Mini Mac the Chrome based Edge has horrible performance. Using Waterfox instead.
