Rules

The rules (as of season 4) are as follows:

• Each player begins with $100,000 in chips ($10,000 in chips in Season 1).
• The initial minimum bet is $1,000, the maximum bet is $50,000 (minimum bet is $100, the max bet is $5,000 in Season 1).
• There are six decks.
• Each player gets one "Burger King Power Chip" per round, which allows a player to switch one card with the next card in the shoe. If used on a double-down hand, the player may look at the double-down card and replace it if desired. The power chip was added as of season three.
• There are two "knockout cards" in the shoe. Once a knockout card is drawn, the player with the lowest amount of chips after the next hand is eliminated. After the first knockout card, the minimum bet increases to $2,500, after the second, the bet increases to $5,000. The deck is shuffled after each knockout card. If there are only four players when the first is drawn and three when the second is drawn, no players are eliminated, but the minimum bet still increases. The knockout cards also appeared first in season three.
• Players can split, double-down, and insure for less than their bet.
• Players can double-down on anything.
• Surrendering the hand is legal, which allows players to give up half their bet and concede the hand.
• If a player can't make the minimum bet, they are eliminated.
• Blackjack pays 3 to 2, dealer must stand on all 17s and higher (including soft hands).
• After 30 hands in Season 1, the player with the most chips wins.
• After 25 hands in Season 2-4, the player with the most chips wins.
