I live in Indiana. It seems around here we have a lot of Spanish 21 games. I just wondered how good these games are. 8 deck, surrender anytime,double down anytime (even on 4 cards I believe), about 60-65 % penetration, dealer stands on soft 17, blackjack is still 3 to 2. There are some other crazy rules with 7's but I am not exactly sure what that is. Something about getting 3 7's and the payout is larger. Does anyone know what the house advantage on this might be?
