However, the player is afforded numerous other small advantages to compensate for having fewer 10-valued cards. For optimal strategy, check out the Wizard of Odd's page.
Although rules can vary from one casino to another, the following are standard at the time of this writing. Surrender is allowed, which means that if a player is dealt an unfavorable starting hand, they’re allowed to surrender and lose only half their original bet. There are two types of surrender: late and early. Early surrender, which is surrender before the dealer checks their hole card if they have an ace or ten-valued card face up, is exceedingly rare because it reduces the house edge by 0.63%. In a game where the dealer stands on soft 17 or hits with redoubling allowed, permitting early surrender would eliminate the house edge entirely and give the player the advantage. Late surrender refers to forfeiting an unfavorable starting hand after the dealer checks their hole card when applicable. This reduces the house edge also, but by a much smaller margin (0.1%), which is why it’s so much more prevalent. Similarly, double down rescue is also available, so if the player wishes to surrender after doubling down, they lose only one bet instead of two. Doubling after a split, doubling on any number of cards, and re-splitting aces are all allowed. A player 21 always wins, even when both the player and dealer have blackjack. If the player gets a five-card 21, they get a 3-2 payout, a 6-card 21 gets paid 2-1, and a 21 consisting of seven cards or more is paid 3-1. There are also bonuses for getting 6-7-8 or 7-7-7; if the suits are mixed the bonus is 3-2, if the cards are all either hearts, diamonds, or clubs, the bonus is 2-1, and if all three are spades, the bonus is 3-1. If a player has a suited 7-7-7 and the dealer’s face-up card is also a seven, they get paid a “super bonus” of $1000 if their bet is $5-$24 and $5000 if their bet is $25 or more. Other players at the table also get an envy bonus of $50. Hands that have been doubled are not eligible for any of these bonuses, and hands that have been split are ineligible for the “super bonus.”
