I personally avoid Casino on Net, as I found very bad conversions with them.
I’ve seen very good conversions with Casinoblasters who run the affiliate program for Golden Palace, which is a reasonably well known online casino.
They have a tiered structure where they pay up to $250 per player, based on how many players you send each month.
Over the last 3 months doing rev-share with them, I’ve averaged around $225 per player.
If you’d like to sign up for them, you can use my link below, and I’ll make a little extra too.

Best of luck–feel free to PM me if you have more questions about that program in particular.
