Recently visited Treasure Island. They have 1 table of double deck in high staskes with betting limits of $25 to $100. Nobody was playing it when I was there, but from talking to the dealer got the impression the pen was 50%. I assume the rules are the same as the other blackjack games as a pit boss said the rules are the same for all the blackjack games. Anybody have any updated information on this game please post it or if this game has different rules. I just updated the information in Trackjack on all their games. The bottom line is S17, but rather poor pen from what I saw.
