Gambling Adwords Alternate?

I have a website based around gambling and I'm pretty positive adwords won't allow it. What alternatives are there?

they don't have to know....
you can cloak Adwords.
I run gambling ads via Facebook + cloaking and it works perfect !

Thanks for the reply. I'm unfamiliar with cloaking, but I want this to be a reputable site. I'll do some more research into cloaking, is it something that could have negative side effects on the website?

I was mostly looking for other advertising opportunities similar to adwords that allowed gambling. I've considered just contacting some private sites etc, but I was trying to figure out all of my options.
