That's all,just register and play.
However make sure to read the terms and conditions in the casino you choose. There are always some rules to pay attention to. For example you can only sign up once per IP address / household. You might have to leave your phone number (you can receive SMS with extra bonuses for example but if you do not want this, you can opt-out later on in your account). Of course you need to be older than 18 in most jurisdictions. In gerenal: just read the terms and cinditions of the bonus before you sign up. The most siginificant ones we already place on the bonus pages here at free-spins-casino.com.
