A Straight Flush is a poker hand consisting of five cards in sequential order, all of the same suit, ranking as the second-highest hand after the Royal Flush. For example, 5-6-7-8-9 of hearts forms a Straight Flush. This hand is rare and valuable in games like Texas Hold’em or video poker available at licensed online casinos. Players need to understand its position in the hand hierarchy to assess winning potential and make informed decisions during play.

Straight Flush Hand Ranking and Formation

The Straight Flush beats Four of a Kind but loses to the Royal Flush, which is specifically Ace-high (A-K-Q-J-10 of one suit). Cards must be consecutive without gaps, such as 10-J-Q-K-A of spades, and the highest card determines ties. In standard poker variants played online, the Ace can rank high or low in straights but not wrap around.

Odds and Payouts

In five-card poker, odds of a Straight Flush are approximately 72,193 to 1, making it highly unlikely. Video poker paytables often award 250 coins for a Straight Flush on a max coin bet, varying by game rules. Understanding this helps players evaluate risks in licensed casino games.
