It would appear that they believe you and your co-defendants were orchestrating the entire operation, at best telling your clients how to skirt the rules and mistakenly instructing them to commit illegal acts, or at worst encouraging them to drum up business and increase profits by engaging in illegal acts. Those are, of course, matters you should be discussing with your lawyer.
You still haven't explained the "jackpots". I expect the GBI is also skeptical of the idea that winners preferred to thumb through catalogs for their trinkets, and would wait for delivery then come back later to pick them up. The reason that arcades have the prize counter stocked and ready is because gambling is driven in large part by impulse and instant gratification.
