Blackjack rules at live tables vary in a handful of places that matter. The number of decks, whether the dealer stands or hits on a soft seventeen, when doubling is allowed and whether surrender is offered each shift the edge by a fraction of a percent. Payouts on a natural are the largest lever: three to two is standard, and a table paying six to five takes several times more from every player over a session.
Roulette comes in versions with one zero, two zeros and extra features. A wheel with a double zero nearly doubles the house edge compared with a single zero wheel, and some tables add a triple zero pocket on top. Variants with random multipliers pay more on a few lucky numbers and less on every other straight bet. Speed and automatic versions keep the same odds and simply spin faster, which raises the cost of an hour.
Every live table publishes its own rules and return figures, usually behind an information icon in the corner of the video. The return is given for each bet, and the figure for the main bet is the one to compare between tables. Two tables with the same name in the lobby can carry different rules if they come from different studios. Opening the rules panel before the first round takes less time than a single hand.
