Wow!!! I don't know that SLM.GAMES is here. As I saw the ANN thread, I tried to check the casino site to know more about the site, and well the site is okay, but I didn't see football sport except racing sports. And the only game I saw that is more in the site is dice. I will advise the op to make the casino more popular in the forum.
When you say "Make casino popular in the forum", you are asking them to start a signature campaign as that is the only and best way to promote the casino on bitcointalk.
Although Signature campaigns are not a necessity but when you see a lot of other gambling sites are popular here because of their extensive promotion, this leave no choices for the new casino to follow them and start an aggressive campaign to compete them.
