Flush poker

A flush is a poker hand where all five cards belong to the same suit but do not form a consecutive sequence, which would instead make it a straight flush.

Five cards of the same suit, not in sequence1
Ranking position
Below a full house and above a straight1

Highest card decides; if tied, compare second, third, fourth, then fifth1
Alternative names

Key points

  • A flush requires five suited cards that are not consecutive; if they were consecutive it would be a straight flush.1
  • In standard poker hand rankings the flush sits below a full house and above a straight.1
  • When two flushes compete, the hand with the highest top card wins; if those match, the next highest card is used, and so on through all five cards.1
  • The term 'flush' is standard across poker and other card games that score by suit; no alternative name is commonly used.12

How a flush works in play

  1. A player makes a flush when their hand contains five cards of the same suit and those cards are not in sequence.1
  2. If two players each have a flush, compare the highest card; the player with the higher top card wins.1
  3. If the top cards are equal, compare the second-highest, then the third, fourth, and fifth cards in order.1

Flush in broader card games

Beyond poker, the term flush appears in other card games that score hands by suit. For example, in the game Loo, a flush is a hand of five cards of the same suit and ranks above a sequence.3 In Chinese poker, a flush is one of the standard hand types used to compare players' hands.4 The concept also appears in the Indian game teen patti, where a flush is called a 'colour' and ranks below a straight flush but above a straight.5
