I have one that I got for free. My kids liking pumping the tokens in and hitting payout more than actually playing. I think it's totally boring.
Most of my guests don't even bother playing, if they do, it's usually less than a minute.
I think Howard said the thrill is gone because it's not real money, that's true in this case.
I also have a real Video Poker that gets some use, but I tell people it's for real. It takes quarters and paper money, and if they lose, oh well

But if they win, I pay. It gets alot of play when I host the neihborhood poker games. I've never had to pay the $1000 prize

, but I have paid $100.
BTW, if they really want to play for free (like my mom), then that's ok too.
