Conveniently, the provably fair system for mines is not implemented. I am currently communicating with support to see if this is some sort of error or mistake, will keep you posted.
This is the first time that I am hearing about this site. I usually avoid gambling site names that start with lucky since they tend to be scams in some way or another.
I wouldn't call this particular site a scam yet, but their provably fair system failing is a big red flag and these results don't bode well for the future of this site. Check whether the provably fair system is working properly before gambling here people.
