Just got back from Winstar, a huge Casino on the Oklahoma/Texas border. Was going to sit down on a Blackjack game and noticed the worst odds I have ever seen. They have the Oklahoma Tax of .50 a hand and they had a automatic shuffler(6 decks). I made a mistake of putting down a $100 but quickly asked for my money back without playing a hand. I would guess the house odds are 10% or better. The same anti (.50) tax is played on craps and roulette and all other card games. We were comped one night from a previous trip but then were charged a $10 resort fee. The slots were ok but thats all we played.
