I can't speak for the Class II slot machines, which I never play. (What's the fun of just pressing a button with no skill involved?) But Buffalo Run has the very best odds on video poker, Class III [RPG] machines with 99.5% payouts! I've found no other casino in Oklahoma which pays 9 on a full house, 6 on a flush. And you get these optimal odds, whether you play quarters or dollars. So I can afford to play max bet, which offers 4000 on a full house (vs 250 payout on 1). At max quarters, that pays $1,000 - conveniently just below the threshold for IRS reporting. By comparison, the nearby downstream pays only 8/5, and the Winstar pays an atrocious 7/5. The Grand pays 8/6, but only on dollar bets. If you are a savvy gambler whos attention to the pay tables, video poker at Buffalo Run is your very best bet.
