Just another casino review website! I am not sure how are you planning to survive amongst the competition. Make use of the cool domain name that you had managed to procure. Focus on SEO and make use of tools like ubersuggest to make your SEO better.

Another possible way you can explore is aggregator model. For each of the casinos listed on your website might also have been reviewed by another reviewers. So try to show their ratings as well in your website through backlinks and ask other review websites to do the same for you. Such kind of link exchange should work well from SEO perspective and also users will have a one stop shop for casino reviews.
