Since they are showing an interest for arts then provably they are heading to promotion. Maybe they just need to receive some recommendations towards possible running an art contest since we able to see that doing good since the other big casino is doing really great for having those contest.
I say this because it's very important we understand that what works for A might or may likely not work for B, business strategies, as well as marketing strategies differs for different companies, and personally, I think it's best for every company to find what works really well for them, rather than try to copy what other company is doing.
