When I use the site on my Galaxy tablet A the dice rolling animation is unbearably slow. I've tried a good bit of troubleshooting but nothing has helped. Is the tablet it's self or a software issue on site that isn't compatible with the device?  Anyone else have the issue or solution? 

Try turning the dice shadow quality down, but other than that I can't offer much advice. The dice are slow on my mobile devices as well, including my thinkpad.
