This is an individual problem, super gambling people can not help. I treat casinos like entertainment.
You should treat gambling as an entertainment because the chances of winning in gambling is very less. If you aim to gain money from gambling, you will be disappointed in most of the cases.
I assumed their site is too damn slow.
I think they're using some kind of cheap hosting which can't handle the traffic and get crashed.
Also, did you block some countries?
Sometimes the site loads so slow at my pc even on the fastest internet connection. Maybe the site is not optimized for all the browsers. I jst load the site and it doesn't load full.
