One of the most confusing things for any new poker player is the order of hand rankings. The poker hands listed below are ranked from the Royal Flush (highest) to the High Card (lowest). These hand rankings are generally consistent throughout every variation of online poker.

Royal Flush

Ace, King, Queen, Jack and Ten all in the same suit.
If two or more Royal Flushes exist at showdown, the pot is split.

Straight Flush

Five cards in numerical sequence all in the same suit.
Tied Hand: If two or more Straight Flush exist at showdown, the highest ranked card at the top of the sequence wins the pot. If two or more identical sequences exist, the pot is split.

Four of a Kind

Four cards of the same rank with fifth card being the highest eligible card.
Tied Hand: If two or more Four of a Kinds exist in a hand, the highest four of a kind wins. Games played with community cards where players have the same four of a kind, the highest fifth card by rank (kicker) wins. If the kicker is also of the same rank, the pot is split.

Full House

Three cards of matching rank with two cards of different matching rank.
Tied Hand: If two or more Full Houses exist at showdown, the highest three matching cards wins. Games played with community cards where players have the same three matching cards, the highest value of the two matching cards wins. If the hands are identical in rank, the pot is split.

Flush

Five cards of matching suit.
Tied Hand: If two or more Flushes exist in a hand, the player holding the Flush with the highest ranked card is the winner. When necessary, the second, third, fourth or fifth highest cards are used to break a tie. If two or more exactly ranked flush hands exist, the pot is split.

Straight

Five cards in ranked sequence.
Tied Hand: If two or more Straights exist at showdown, the player holding the Straight with the highest ranked card is the winner. If two or more exactly ranked straights exist, the pot is split.

Three of a kind

Three cards of matching rank with two cards of different ranks.
Tied Hand: If two or more Three of a Kinds exist at showdown, the highest Three of a Kind wins. Games played with community cards where players have the same three matching cards, the highest ranked fourth (or fifth when necessary) card wins. If the hands are identical in rank, the pot is split.

Two Pair

Two cards of matching rank with two additional cards of a different matching rank. The fifth card is an unrelated rank.
Tied Hand: If two or more players have Two Pairs at showdown, the highest pair wins. If the highest pair is the same rank, the highest second pair wins. If both pairs are identical, the highest fifth card by rank (kicker) wins. If the kicker is also of the same rank, the pot is split.

One Pair

Two cards of matching rank with three additional cards of unrelated ranks.
Tied Hand: If two or more players have One Pair at showdown, the highest pair by rank wins. If pairs of the same rank exist, the highest ranked unrelated card wins. The second and third highest ranked unrelated cards are used when necessary. If the hands are identical in rank, the pot is split.

High Card

Five cards that are not of the same suit, are not ranked sequentially and uniquely ranked.
Tied Hand: If two or more players have High Card at showdown, the highest ranked card wins. The second, third, fourth and fifth highest ranked cards are used when necessary. If the hands are identical in rank, the pot is split.
