Am a life time Oregon resident and over the past 20 years have played at all the Indian casinos in Oregon. NEVER have I walked out with more money than I entered with and I am NOT a careless or wild gambler! I set a limit and than go home. I have played the same bank of machines at Indian Head every time I go, for 9 years now, and after thousands of spins, have never gotten the Jackpot payline or seen anyone else get it. I doubt that the machines pay above a 60% rate.
