All hands are ranked based on the strength of any 3+ card flush. The goal of this game is simply to make the highest flush ranking possible (multiple cards of the same suit) using the 7 cards you are dealt. Just like other popular poker-based casino games such as Three Card Poker or Caribbean Stud, High Card Flush is played against a dealer using a 52-card deck.
First introduced in 2011, High Card Flush is a fairly new table game that was inspired by flush rankings in poker.
