Blackjack Flush Rules, Payout & Side Bets

blackjack flush rules payout

In casino card games, a flush is a hand that contains five cards all of the same suit. If you’re playing a game such as texas hold’em or video poker, this can be considered a good hand. However, some players mistakenly believe that the same is true in blackjack.

Unfortunately, that’s a rookie mistake, because this is not the case.

However, there are several blackjack side bets available that pay out on a flush. So if you’re looking to add some excitement to your game, make sure to check out the betting options at your favorite casino.

In this guide, I’ll explain the blackjack flush rules for standard blackjack (spoiler: there aren’t any) and also show you some variations and side bets in which a flush does make a difference.

What is a flush in blackjack?

A flush is a hand where all of the cards are of the same suit.

For example, if you have a hand with the following cards: 2 of clubs, 4 of clubs, 4 of clubs, 6 of clubs, and Ace of clubs, you would have a score of 17, but since all the cards are clubs, it would also technically be a flush.

If you happened to be playing poker then this would be a hand worth smiling about (inwardly of course). But in Blackjack, the rules are different…

What are the rules if you get a flush in blackjack?

In the standard rules of blackjack, a flush is only worth the same as a regular hand. The suit of the cards is not important, blackjack only counts the cards’ value.

There are no extra bonuses for hitting a flush in blackjack, so it’s not a hand that you’re going to be striving for.

What side bets are available that pay out on a flush?

There are a few blackjack side bets that will pay out if you hit a flush (or part of one – most of these bets don’t require 5 cards).

But these aren’t available at every table – you need to be playing the relevant version of blackjack in order to place a side bet.


This is a side bet that you can place in addition to your regular blackjack bet. It’s based on three cards: the first two cards that you’re dealt, as well as the dealer’s up-card.

There are several combinations that pay out in 21+3 blackjack, one of which is that when your first two cards and the dealer’s up-card make a 3-card flush, then you’ll win this side bet.

The payout for hitting a flush in 21+3 varies from casino to casino, but it’s usually around 5-1. This means that if you bet $10 on the 21+3 side bet, and you hit a flush, you would win $40-$50.

A more exciting payout comes when the three cards make a straight flush. This is when the cards have consecutive values, such as 7 – 8 – 9 and are also of the same suit.

A straight flush in 21+3 pays out at 40-1.

Then there’s the biggest payout, the suited triple. This is a combination of a flush and 3-of-a-kind. The cards must all be of the same suit and the same value.

It’s very difficult to get, but if you strike lucky, the suited triple pays out at 100-1.

Perfect Pairs

Perfect Pairs is a side bet that doesn’t actually require a flush per se, but it does pay out extra if the cards are of the same color.

The colored pair requires you to get two cards of the same value and the same color (red or black). It pays 12-1.

Lucky Ladies

Lucky Ladies is a side bet that pays out if your first two cards add up to exactly 20.

When your hand value is 20 and your card is suited, Lucky Ladies will pay out 10:1.

If your two suited cards are also of the same rank (i.e. two ten of clubs, two jack of hearts, etc( then the payout increases to 25:1.

Super Sevens

Super Sevens is a side bet that pays out if any of the initial cards dealt to you is a 7.

The payout increases if you get a pair of 7s, and increases yet further if your third card is a 7 as well. If this does happen, then the suit of the cards does become relevant, and a flush pays out big time.

  • Two suited sevens pays 100:1
  • Three suited sevens pays 5000:1

This is the biggest payout for a blackjack flush I’ve found. Notoriously difficult to get of course, but absolutely amazing when it does!

Royal Flush in Blackjack

A Royal Flush is not part of the regular blackjack rules and does not feature in any standard online blackjack version or side wager. But it is used in some progressive blackjack games such as “Super 4” and others.

In these instances, the Royal Flush is usually the hand that triggers the progressive blackjack jackpot win.


In conclusion, the blackjack flush rules are that there are no rules. A flush in most blackjack games is nothing to get excited about – it’s just another hand and should be treated according to its value, not its suit.

However, there are a few side bets that will pay out if you hit a flush, so if you’re feeling lucky, give them a try. But don’t forget that all side bets come with a house edge, so make sure you have enough chips to cover a losing run.
