The interface is simple indeed, too simple for my taste to be honest!
Dice game is simple and it does not require to have too complex UI.
I agree... but I believe we all have the ones we like more than others! In my case it's Wolf, and when I play dice game on any place I compare it with Wolf in my head! Interface, auto betting options, many currencies, flash betting! So, too simple is just my opinion... of course, dice games don't require complex UI or anything, but in order to draw my attention it's either that or some awesome promotions!
