You don't get 100 free sat anymore when creating an account? I tried to play a game at work (using a different computer, username and other connection) but my randomly new generated character didn't have the free 100 sat so I wasn't able to play for money (I don't want to have access to my BTC at work to be honest)
you should have gotten it, if this work IP hasn't been seen before by the server. will verify that everything is ok.
btw you can also ask anyone on the server for some satoshi to play with
