Filtering for game portal - Need Advice

Hello!
I have an gambling content website for CIS countries players and i need accurate filtering for games presented on it.

Now i have filter like this:

(it works only on page sloto.top/games)

And have many options, like: Vendor, Game Type, Rating, Bonus Spins, Wild, Scatter etc.:

And my question is:

Can anyone tell me, how i can get profit for SEO from my filtering results pages?
Can i generate text for this pages basing on filtering criteria?

Hi Slototop! The same question I was asking myself several months ago. I launched a test site with just one page where a list of 90 casinos and bonuses was displayed. Also I set up a select box to filter that list by providers. After a month I quit that test site and then deployed a new one with the same domain name casinobonusocean.com.

During first week after deployment I was receiving an average of 50 active users per day from google search until I submitted the new sitemap. After some research I discovered that the filters from my previous site still were in the search results. All those visits were from the urls created by php filters like site.com/aaa?bbb=ccc.

The filter path works like any url. You can also generate keywords and description as result for each possible filter(or for most important ones) if you create the corresponding columns in your table.

Кстати, я знаю русский. Если что, свяжись со мной, но знай, что я новичок в этом деле.
