To everyone who says “it’s the same game”—it’s totally NOT. The house edge can be a little better in certain online versions because they offer 3:2 payouts more often and let you double after splitting. In live games, especially in Vegas, lots of tables now pay 6:5 or force the dealer to hit on soft 17, which is worse for the player. So your expected return can vary by A LOT depending on the version and the ruleset you get.
