LOL there is no way I would ever copy the code on this page. I mean really? the page has a red background with red font? From a UI/UX perspective this is a disaster and I hate to break it to you but a casino isn't a new idea... There about a million online casinos and just in the last year there has been about 100 new bitcoin casinos.
But you have said that you are copying his idea on this thread so I would tread lightly if I was you, plus:
Yes, I know someone will get that reference
I guess you don't really understand what qualifies as copying. I can say all I want I am going to copy google's idea of a search engine or copy bitcointalk.org and create a bitcoin forum but no matter what if I write all my source code and aren't stealing anything, then there is nothing to sue about.
Once again, do you think all these dice casinos popping up are someones orignal idea? No, they saw a company like just-dice and said oh that's a good idea I want to do that and did it. There is nothing just-dice can do unless they stole their source code.
