Blackjack: An initial two-card hand consisting of an Ace and a 10 (or card of value 10 i.e. a jack, queen or king). The total value of the hand is therefore 21.
Bust: A hand worth more than 21 is called Bust.
Double Down: The option of doubling the bet at the start of a hand and requesting a final card from the Dealer.
Even Money: Offered instead of Insurance when the Dealer's face-up card is an Ace, and the player has been dealt Blackjack. If taken, the Player accepts a winning bet at the normal 2:1 level instead of the 3:2 for Blackjack.
Face-Up Card: The face-up card is the first card dealt to the Dealer. The player can use it to judge how strong the Dealer's hand is and alter their strategy accordingly.
Hit: Requesting another card from the Dealer.
Insurance: Offered when the Dealer's face-up card is an Ace. Insurance is a side bet of half the original bet which pays out if the Dealer has Blackjack, so that the Player breaks even overall on the hand.
Max All/Min All: Betting the maximum/minimum possible at each position.
Push: A hand that is of the same value as the Dealer's hand.
Re-bet: Betting the same stakes as the previous round.
Split: The option of splitting a hand into 2 hands when both cards are of the same value.
Stand: Finishing playing a hand.
