Casinos in different parts of Nevada have different payouts. You wouldn't believe some of the small towns. Especially on Keno. But gosh not as bad as that example of an Indian casino. More reason why I categorize them with Illegal chips!
Wait till you hit a royal flush & they come over & you expect to be paid & they tell you leave we are not paying you! Happens in the smaller places too. The big ones like Harrahs; have reputations & wouldn't risk it. I hope. When Nevada refuses to pay you. As in a case recently on a casino paying double on certain royals but when hit saying, "oh, but not today it is a Holiday"! Then the Gaming Commission is called & comes out right away. Later a settlement is reached where if the rules are posted & you read them correctly, as in this case, you are paid 100%. Try calling the Indian Gaming Commission!
