That URL is very good for computers, but it is lacking for phones or tablets. Not because it is not entirely functional in those devices, but it does not uses the unique characteristic they have that normal computers and notebooks do not.
If you use an Android device, for example, you could download this app:
https://play.google.com/store/apps/d...infusoft.dados
Then, to through a (or many) dice you would simply start up the app and shake your phone!
What? Don't use an Android device? Well, in that case you could trash the piece of junk you've got and get an Android device!
Now, seriously, just search for the word "dice" in your application center (however it is called) and something tells me you will find one just for you.
