This only applies to the new edge browser that uses chromium as its engine not the old one (Recently released via Windows Update)
You will need to follow these steps to enable flash and then allow the game to run flash as well
- Open settings in edge (the 3 dots top right)
http://prntscr.com/vp08bm- Select Cookies and site permissions
http://prntscr.com/vp08vx- Toggle global option to ask (default is disabled)
http://prntscr.com/vp09bo- Open site permissions (it looks like the global settings but it isn't)
http://prntscr.com/vp09x3- Change Adobe Flash from Ask to Allow
http://prntscr.com/vp0au3- Refresh the page with the refresh button for flash to start

You can then start the game.
Once the browser is closed and started again you will need to go back and complete step 4 - 6 before starting the game again.
