I set it into 60% chances of winning per betting the dice and the target multiplier is 2.
Isn't it 50% chance of winning when you set 2x multiplier?
Bustadice is quite similar to bustabit and I have once tried to beat bustabit using custom script but I actually lost so much overnight. So I would say bustadice will also have same chance of winning like in normal dice site. That's why don't expect to see a huge profit from bustadice.
