The basics.
1. Understand the cards and their values
Poker is played with a standard deck of 52 playing cards (except for Ross Perot Poker, which is played with less than a full deck). The cards are ranked from high to low in the following order: Ace, King, Queen, Jack, 10, 9, 8, 7, 6, 5, 4, 3, 2. Aces are ALWAYS high. Aces are worth more than Kings which are worth more than Queens which are worth more than Jack, and so on. The cards are also separated into four suits. The suits are:
Clubs: 
Spades: 
Hearts: 
Diamonds: 
Each player is dealt five cards. The object of the game is to end up with the highest-valued hand. From best to worst, hands are ranked in the following order:
Straight Flush
Four of a Kind
Full House
Flush
Straight
Three of a Kind
Two Pair
One Pair
High Card
Royal Flush
This is the most valuable hand in all of poker. A Royal Flush is composed of 10, Jack, Queen, King and Ace, all of the same suit. It’s the toughest hand to get.
Straight Flush
A Straight Flush is comprised of five cards in numerical order, all of the same suit. It’s not allowed to “wrap around,” such as Q-K-A-2-3. This is also very rare. If you get two of these in a row, you are cheating. If there are two Straight Flushes at the table, then whichever hand’s Straight Flush reaches the highest card value wins. So in the examples below, Hand 2 (which has a King) would beat Hand 1 (which only goes up to 8).
Four of a Kind
Four cards of the same numerical rank and another random card. If there are two or more hands that qualify, the hand with the highest-ranking Four of a Kind wins. In the examples below, Hand 2 would beat Hand 1.
Full House
Of the five cards in your hand, three have the same numerical rank, and the two remaining card also have the same numerical rank. Ties are broken first by the Three of a Kind, then the Pair. So Q-Q-Q-3-3 beats J-J-J-A-A, which beats J-J-J-2-2.
Flush
A Flush is comprised of five cards of the same suit, regardless of their numerical rank. In a tie, whoever has the highest ranking card wins. In the example below, Hand 1 (with a King) beats Hand 2 (with a Queen).
Straight
Five cards in numerical order, regardless of their suits. Just like with the Straight Flush, a Straight cannot “wrap around.” In a tie, whoever’s Straight goes to a higher ranking card wins (so in the examples below, Hand 1 beats Hand 2).
Three of a Kind
Three cards of the same numerical rank, and two random cards that are not a pair.
Two Pair
Two sets of pairs, and another random card.
One Pair
One pair and three random cards. If more than one person has a One Pair, then the person with the highest ranking pair wins.
High Card
If none of the players have anything of value, the player holding the highest-valued card wins, with the 2 as the lowest card, and the Ace as the highest. In the case of a tie, you move to the next highest card, and continue.
