It's possible to log in from your phone. I have a s2 note and I downloaded Photon Browser from the play store for the flash plug in. It feels a little cumbersome. If you don't know the figurines well it would be too slow for you to look up info and really plan your moves. Still I thought it was pretty cool.

It is also possible to play using default browser on older andoid versions, which had flash. Also Firefox for Android support flash (and sometimes Photon Browser looks surprisingly similar to it).

I used to play on my 7" tablet, but it is very tricky and slower (you need to be very precise with actions), so proper UI is needed much. Working hard towards it.
