Rank of Hands

In poker, players compare five card hands against each other to determine who wins. A player with a flush has a better hand than a player with a straight, for example. The following list is from best to worst, so any hand on the list beats any hand below it and loses to any hand above it.
Royal Flush - An Ace-High straight of one suit.

Straight Flush - A straight of entirely one suit.

Four-of-a-Kind (Quads) - Four cards of the same rank.

Full House (Full Boat, Boat) - Three-of-a-kind and a pair. The example below would be called "Queens over Aces" or "Queens full of Aces".

Flush - Five cards of the same suit.

Straight (Run) - Five cards of sequential rank. Note that in hold 'em, Aces can be high or low.

An example of a straight where the Ace is low:

Three-of-a-Kind (Trips, Set) - Three cards of the same rank.

Two Pair - Two cards of the same rank and another two cards of the same rank. The example below would be called "Jacks and Twos".

One Pair - Two cards of the same rank.

High Card - When you don't have any of the above, your highest card determines your hand. The example below would be "King High" or "High card King".
