Very easy to use. And you do not need to buy anymore coins unless you want to. Just wait until the next today for transfer free coins. And if you can gamble 5 thousand in free coins when balance built up enough to can win hundreds of millions in. In credits. My highest coin credit has been around 32 Billion in credit coins. It is really good fun. And you an gamble with your coins costing you nothing this is a great way to play.
