The Pioneer offer is not based on machine play. You don't have to play other than run the freeplay off. Anyone off the street can use it. Harrah's, Golden Nugget and Tropicana don't have any video poker worth playing to get free rooms. You're better off paying for them. But December is coming up which is the slowest month in Laughlin. Most places practically give the rooms away. The Pioneer offer is open to everyone.
So far the Riverside is the only place that's sent me anything and it's not much, $20 freeplay for December. And I ran a 20K wager. I guess they think that will get me to bite. They sent me their King of Clubs Newsletter. They want me to "Go Green." That is, receive all the offers by email. But when I click on the link it won't open.
