"How can I get my affiliates to see the benefits of playing games like Knockout Trivia so they will play them?"
Good question. Tel your affiliates to take part in the free games first. If they knocked out, tel them to see the game towards end. It's very knowledgeable. If any one watch the game he can get various knowledge in various fields.
If you win you get TCs, which you can use in bidding and in games also. This will award you a prestigious badge also.
