Sweepstakes Casino Affiliate Programs?

Hey everyone,
This is a pretty niche question, but if there is anyone else working in the sweepstakes casino vertical:

What affiliate programs do you use and what does your commission look like?

All of the programs I have found are so fragmented its hard to know if I'm getting stiffed on an offer. I am also worried that I am just completely missing some big programs, despite me looking very hard.
I'm currently running deals with PriorityPlay, Sweepsflow, MagicClick, algoaffiliates, and chameleonAds. I also run a few more direct partnerships, but even with all these networks I have less than 50 links!

Has anyone found other programs?
