"Jacks or Better," sometimes simply called "Draw Poker," is the most common variation of video poker. Payoffs begin at a pair of jacks. Full pay Jacks or Better is also known as 9/6 Jacks or Better since the payoff for a full house is 9 times the bet, and the payoff for a flush is 6 times the bet.
High: Any card that is a Jack or higher. Low, on the other hand, refers to all cards that are lower in value than a Jack. Examples of high cards include Ace, King, Queen, and Jack, while low cards run from 2 through 10.
Royal Flush: Refers to five sequential cards of matching suit starting with 10 and ending with Ace. This is the highest paying hand in Jacks or Better.
Straight Flush: Comprised of five sequential cards of similar suit up to 10 (e.g. 6, 7, 8, 9, 10).
Four of a Kind: Refers to four cards of the same number. For instance, four Kings or four 2s.
Full House: Consists of a hand with three of a kind plus a pair (e.g. three 7s and two Kings).
