High Card Flush Explained

High Card Flush is a casino table game where you and the dealer each try to build the longest flush — the most cards of a single suit — from seven dealt cards. Unlike standard poker, pairs, straights, and full houses don’t exist here. The only thing that matters is how many cards you can string together in one suit, and the longer flush wins. If both flushes are the same length, the highest card breaks the tie.

How the game is played

High Card Flush is a one-on-one game against the dealer, not against other players. The basic flow:

1. Place an Ante bet to start the hand. (Optional bonus side bets are usually available too.)
2. You and the dealer each receive seven cards. Yours are face up; the dealer’s stay hidden.
3. Find your longest flush — the largest group of same-suit cards in your seven.
4. Decide to fold or raise. Fold and you lose the Ante. Raise and you add a Play bet (typically 1x to 3x the Ante, depending on how strong your flush is).
5. The dealer reveals and forms their own longest flush. Higher flush wins.

The whole game turns on one comparison: whose flush is longer, with high card only as a backup.

How flushes are ranked here

The ranking rule is simple and always applies in this order:

1. Length first. More suited cards beats fewer, every time. A four-card flush beats any three-card flush, no matter the ranks.
2. High card second. Only when both flushes have the same number of cards do you compare the top card, then the next, and so on down the line.

Your flush	Dealer flush	Winner	Why
4 cards, K-high	3 cards, A-high	You	Length beats rank
4 cards, Q-high	4 cards, K-high	Dealer	Same length, higher card
4 cards, A-J-9-4	4 cards, A-J-9-2	You	Same top three, higher 4th
5 cards, 10-high	4 cards, A-high	You	Length beats rank

This is why the game is named High Card Flush: the high card is the tiebreaker once the flushes match in length. For the broader idea of comparing flushes card by card, see does a higher flush win.

Do you play high card on a flush?

Yes — but only as a tiebreaker, never as the primary measure. The number of same-suit cards is always compared first. The high card comes into play only when your flush and the dealer’s flush are the same length. So “do you play high card on a flush?” has a precise answer: the high card settles the hand exclusively when both sides have equal-length flushes. If your flush is even one card longer, its top card is irrelevant — you already win.

A worked example

You’re dealt seven cards: A♠ K♠ 9♠ 4♠ J♥ 7♦ 2♣.

• Count your suits: four spades (A♠ K♠ 9♠ 4♠), plus singletons in hearts, diamonds, and clubs.
• Your longest flush is a four-card spade flush: A-K-9-4.

The dealer turns over a four-card club flush: A-Q-8-3.

Both flushes are four cards long, so length ties and you drop to the high card. Yours starts A-K, the dealer’s starts A-Q. The aces match, so you compare the second card: your king beats the dealer’s queen. You win. Notice that if the dealer had held a five-card flush of any ranks, they’d win outright — length always comes first.

How it differs from poker flushes

It’s worth being clear that this game does not use standard poker hand rankings at all. In real poker a flush is always five cards and sits below a full house and above a straight. In High Card Flush, flushes of any length are the only hands, and there are no pairs or straights to worry about. If you want the standard poker version, see poker flush rules and how many cards are in a flush.

Quick summary

• High Card Flush is a casino game played one-on-one against the dealer.
• Each side forms the longest flush — the most cards of one suit — from seven cards.
• Length is compared first; the high card only breaks ties between equal-length flushes.
• It is not standard poker — no pairs, straights, or full houses apply.

Bottom line

High Card Flush rewards suit length above all else: build the longest flush you can, and lean on the high card only when your flush ties the dealer’s in length. Count your suits before you admire your aces.
