I am interested in creating a casino-like gambling online website. I am currently living in California, so I would like to know how does it works in this state. How much taxes do I have to pay on profit? This game is an from my invention, so how can I copyright my creation? how much does it takes? In addition, it is legal to do any kind of advertisement for my website? What do I have to write in the legal terms of my website? Finally, in general, what is required to create my online gambling game 100% legal?
