Welcome to crypto gambling world. Mabye the site is still in beta phase?
It's not a normal casino like others (Decentralized Social Gaming Platform). I thought there is only dice game as the site name is dice.one but I'm wrong. There are more other games as well. Couldn't understand properly how to deposit or withdraw from there. Only EOS is well known coin I can see in deposit function. A video guideline would be more helpful to understand the site well.
