For any top game software casino, if you complete all of the documents necessary for withdrawal, like credit card authorization form, id, utility bill.  They will give you $30-$50 free.  I got it from Gold vegas easily (recommend this casino), as soon as they reiceive it, contact livechat they will credit it for you right away.  I got it from Rome also, but kinda hard, because they keep saying missing this and that or make you wait, eventually they have to give it to me. 

7spins casino:  I like this casino because of their promotion, but they do not honor what they said on their website, I have to go thru negotiation with the livechat everytime I make a deposit and they don't give me the $50 for completion of all the documents.  They gave me $20 only

But anyway, if you deposit to these casinos, and want your money, just do this.
