I don't like much the design, specially the colors. Combine this with the type and size of the font you used and the result is that your site is hard to read.
not so good design and all content not original google will ban your site in no time. try and develop something unique and not duplication
You should try and focus on one of the topics first, ie only casino and maybe even a sub category, ie slots or roulette and develop on that. Once you have at least 3-5 paragraphs of content, start on the next section and so on and so forth. You should also take a good look at other sites similar to yours and get some design ideas as you site is too simple and too complicated at the same time. Structure it in sections, have a home page that has your best affiliate links/banners then some content, like new casino fo the month or latest review or something. Then you should be rocking
