Dont waste your money
The dealer wins at an unrealistic percentage. If you get a good number, the dealer will almost always push or win. What are your chances when 9 out of 10 times you are dealt 12, 13, 14 or 15 and the dealer shows a face card? You have no choice but to hit (and of course go over) because I learned that the dealer almost always has 17 and above.
Odds are better winning in Vegas, which are not that good.
