Rules, numbers and hosts
Rules. The national catalogue of games that the Superintendencia de Casinos de Juego (SCJ) sets for every casino in Chile: six decks, the dealer stands on every 17, blackjack pays 3 to 2, a double on a two-card 9, 10 or 11, also after a split, the retiro for half the bet except against an ace, and every card dealt face up, the dealer’s second card after the players. The catalogue does not say whether a dealer blackjack also takes a double or a split; the figures assume that it does, the costlier reading. It is a preset for learning, not a statement about any one casino.
Numbers. Every figure on this page is worked out when the page is built, by our blackjack engine. The chart gives, for each hard total, the play with the higher average result over all two-card hands of that total, pairs aside. A mistake’s cost is the average result of the chart’s play minus that of the mistake, per hand, for an example bet of 10 units, with each average rounded to the hundredth first, so a cost is always the difference of the two amounts shown. Against a 10 or an ace the averages include the hands where the dealer makes a blackjack, because at these tables that card comes after you play. The house edge assumes the full chart, soft hands and pairs included, and cards shuffled after every hand; with a cut card it is a little higher, and every move off the chart raises it.
The dealer’s table. The dealer’s second card is dealt after the players, so blackjack is an outcome of its own. Your own two cards stay in the shoe; with them taken out the figures shift a little. A row may not add up to exactly 100 because of rounding.
Hosts. Leo and Maya are illustrated characters. Their backstories, a former dealer and a former floor supervisor, are written for the course: neither is a real person, and neither speaks for any casino. The rules and numbers on this page come from the sources it cites, not from their experience.
No promise. Blackjack is played against the house. The chart lowers the price of playing; nothing on this page makes it free or tells you how an evening will end.
