Have many American casinos outside of Las Vegas adopted 6-5 blackjack, or is 3-2 still considered the industry standard?
From what we know, 3-2 blackjack remains the industry standard in most American casinos outside of the Las Vegas Strip, where the whole movement got started and remains concentrated. The 6-5 game has spread to some degree (especially at lower-limit and single- and double-deck tables), but is far more prevalent here in our hometown.
Even then, many off-Strip and locals casinos have stuck with 3-2 longer to attract players. Indeed, Station Casinos’ VP of casino operations was quoted in a Station blog saying, “I've been very surprised by this trend and the lack of a strong reaction. At Station, we feel that the Strip casinos are taking advantage of their guests. The vast majority of our games are 3-2. We run a small number of 6-5 games on single-deck or low-limit games.”
Of course, 3-2 has gone up in terms of the table minimums. In a recent informal survey we found, only a few $10 tables in Atlantic City were 3-2; the rest 6-5. If you can fade $25 bets, you can play 3-2 just about anywhere.
Inclusive of the higher minimums, we'd say 3-2 is still considered the proper/standard version throughout most of the U.S. -- outside the Vegas Strip's heavy push for 6-5.
