They have no accountability since they are on Indian land even though they have a crepe paper gaming authority. If you cant hit a five spot playing 20 card keno with 100 dollars spent, you are simply being robbed of your money. I can say without hesitation that Winstar must be setting their video keno at 88 percent and probably much lower.
Having lived in las vegas for 20 years I knew slot techs who showed me the percentage of payout on nickel keno machines and the average payout is 92 percent. Investigate this place for highway robbery.
