The Chrome Web Store does not allow gambling-related extensions, so Outmatched Horses is installed manually in developer mode. It only takes a minute. Download the file below and follow the steps.
Download Extension (.zip)Click the button above to download the extension, then unzip the file. On Mac, just double-click it. On Windows, right-click and choose "Extract All". Keep the unzipped folder somewhere safe, as deleting it will remove the extension.
In Chrome, paste chrome://extensions into the address bar and press Enter.
In the top-right corner of the extensions page, toggle "Developer mode" on. A new row of buttons will appear.
Click "Load unpacked", then select the unzipped Outmatched Horses folder. It will appear in your list of extensions.
Click the puzzle-piece icon in your toolbar and pin Outmatched Horses. You open the extension from this pinned icon.
