I don't know why you think satoshimines gives you a better chance to win than other sites. Gambling is gambling, all the sites are risky. Only bet what you are willing to loose, and only bet for the fun of it, not so that "you can win big."
It is just the matter of what kind games you love to gamble and it is a relative questions which can bring a relative answers too.
So if OP much more love to gamble in the games like satoshimines and think it has a better chance to win then it is ok.
I personally think it is same, no matter you play at any kind games it would bring same , a house edge winning.
