Station Casinos' Jumbo Jackpot, a progressive reward paid out on the casino's slot and video poker machines at random intervals. Here's how it works:

First, you have to be a member of the Boarding Pass players' club. It's free to sign up, and all you have to do is give away a little of your personal information. Yes, you get some junk mail, but you also get discount room offers that way, so it's worth it.

Then you take the little card they give you and put it in any slot or video poker machine at one of their casinos. Every time you hit "spin" or "deal" you have a shot at winning the Jumbo Jackpot. It starts at $100,000 and is guaranteed to pay off before it hits $150,000.

yes, the really cool thing is you don't have to actually win anything on the machine you're playing to win the jackpot. You could get three blanks or a bunch of lousy cards and, if you're the lucky one, your machine will freeze up and alarms will sound.

Even if you don't win, you can still get a reward when someone else does. Every single person playing on a machine in any of the casinos when the jackpot is hit wins $50 in free slot play. Not the same as $150,000, but better than a big fat, "You lose."

The Jumbo Jackpot promotion is valid at Green Valley Ranch, Palace Station, Texas Station, Sunset Station, Boulder Station, Santa Fe Station, Fiesta Henderson and Fiesta Rancho.

Stations also offers this at Thunder Valley (tribal casino) in Sacramento, and there are bonuses attached to the basic jackpot ...you can win an extra $50k if you're playing dollar machines and another $50k if you're playing in the wee hours of the morning.

Also here, everyone that is playing with their card in that casino at the time of the bonus win $50 in credits. That's not a bad consolation prize.
