Avoid Maxima Casino; they ran out of money and can’t afford to pay their affiliates.
I would stay away from Gambling Wages and Casino Pays; they seem disorganized, and I don’t trust them. Casino Partners seems to be ethically-challenged. IOG allows scrapers, and they have expressed no interested in cleaning up their mess.
I recommend the following programs:
Casino Rewards
Vegas Affiliates
Revenue Giants
Casino Profit Share
Gaming Partners
Trident Share
Wager Share
Roxy Affiliates
32 Red
