I would like to see a domain with games or casino in it when I am looking for a gambling site,its just my opinion but OP doesn't have anything related to my preference.
I just added another domain name that contains Casino. You can now vote your choice.
Seriously I don't like that casinoox domain,its sounds awkward and doesn't catchy as well.
Seriously but it looks good in logo design. That means it's brandable. And don't forget it's pronounceable and meaningful too.
