I've seen some provocative videos like these
It seems Duel actually is going all in with they strategy of mixing up bizarre scenes with their classical gambling approach...
One thing is having a good blackjack table, but a completely different thing is having a good blackjack table with very voluptuous and beautiful women like those ones.
It is like a mixture of only fans (pornography) and gambling.
I am not an expert at this, but this sounds like a mix which has a lot of potential to make people addicted to Duel.
Anyways, if this continues to work for Duel, I would not be surprised if other casinos started to include their own beautiful women showing their breasts to gamblers...

I have never played at Duel, so I haven’t verified it. However, I have serious doubts about whether the controversial videos circulating on social media show real gameplay or if they are just staged videos with actors. Maybe there is someone who has played at a table like the one in the videos or can confirm that it's just a setup?
Either way, this form of marketing is quite aggressive, if not brutal. I don't know if that was the goal of the people who decided on this kind of advertising campaign, but you have to admit they caught many people's attention, and that's exactly what marketing is about.
