6:5 Blackjack Explained: Is It Worth Playing?

Almost every blackjack strategy guide tells players to avoid 6:5 blackjack. Many newcomers ignore that advice in the excitement of playing at their own expense.

A table that pays 6:5 on a blackjack instead of 3:2 quietly hands the casino a much bigger edge over thousands of hands, cutting into your returns. That’s why it’s best avoided, but don’t take our word for it. Here’s the math.

What Does 6:5 Blackjack Mean?

6:5 blackjack is a variant of the classic game defined by a reduced payout on a natural (an ace plus a 10-value card) one that favours the casino.

Here’s the math. Put a $10 bet on a 6:5 table. If you’re dealt a blackjack, you’re paid 10 x 1.2 = $12. You might not notice the loss until you compare it to a 3:2 table.

On a 3:2 table, the same $10 blackjack pays 10 x 1.5 = $15.

So at the 3:2 table you win $15 on a $10 bet; at the 6:5 table you win $12, a difference of $3. It looks small, but over many hands, and larger bets, it adds up. You get lower returns for the same wager.

6:5 vs 3:2 Blackjack Payouts

The table below highlights the differences in payouts in the comparison of 6:5 vs 3:2 blackjack based on common minimum bets for a natural hand.

Bet	3 to 2	6 to 5
$10	$15	$12
$25	$37.50	$30
$100	$150	$120

The bigger the bet, the bigger the gap between 6:5 and 3:2.

Why Casinos Switched to 6:5

Many casinos switched to offering 6:5 blackjack to get higher profits. It is primarily for their profitability. They often entice players to play 6:5 blackjack by promoting supposedly favorable rules. One of the most common is a "special single-deck game.” Casual players often fall for this, forgetting the poor payout.

To further understand why 6:5 blackjack is bad, let’s do a quick calculation.

Over 100 hands at the 6:5 blackjack table, if a player hits blackjack 5% of the time, placing a minimum bet of $10, the total winnings would be only $60. However, the same bet in a 3:2 blackjack game would result in total winnings of $75 over 100 hands. The casino has made a total of $15 from the player playing the 6:5 blackjack. With multiple players at the table and thousands of hands played, the house benefits significantly.

How Much Does 6:5 Increase the House Edge?

Blackjack has a low house edge of about 0.5% when you play basic strategy, the best odds on the floor. A 6:5 payout adds 1.39% to that, pushing the house edge to about 1.9%, nearly 2%.

A 1.9% edge means you lose money roughly four times faster than at a 3:2 table. For example, a casual player will play 350 hands an hour at $100 a hand. At a 3:2 table (0.5%), the expected loss is about $175 an hour. At a 6:5 table (1.9%), it jumps to about $665 an hour — roughly $490 more, every hour.

Should You Ever Play 6:5 Blackjack?

You should avoid the 6:5 blackjack at all times. However, you can play if:

1. It is the only table available.

2. You are playing for entertainment only.

3. You’re betting only tiny amounts, so the absolute difference is trivial.

Outside of these three reasons, you should always play 3:2 blackjack games. Keep in mind that a lot of casinos are now placing their 3 to 2 blackjack games in the high-limit room. So, if you don’t see a 3 to 2 game on the casino floor, that may be because it is in the high-limit room.

How to Spot a 6:5 Blackjack Table

Many players, especially beginners, unknowingly sit down at a 6:5 table, assuming all blackjack tables are the same. Here’s how to identify a 6:5 blackjack table:

Table signage

Casinos commonly display a payout sign on the blackjack table. If you see 6:5, walk away without a second thought.

Felt markings

If you check a blackjack table and see it is marked on the felt with “Single Deck”, do not rush to place a bet. It can be a marketing tactic for the 6:5 blackjack. Sometimes the markings can be “Blackjack Pays 6 to 5.”

Ask the dealer

To get the best opinion about a blackjack table, ask the dealer what the payout is before you place a bet.

Casino app

If you are playing online and there is no clear separation between blackjack games, check the game's payout table.

Pit signage

Casinos sometimes make 6:5 table signage highly visible to attract casual players who might initially think 6:5 is better blackjack odds than 3:2.

Does Basic Strategy Change on 6:5 Tables?

No, the basic blackjack strategy remains the same. The payout changes, but it does not affect the mathematically correct playing decisions. You can download blackjack strategy charts for free and use them at either a 6:5 or 3:2 table.

Other Rule Changes That Matter

The 6:5 payout offer isn't a blackjack table rule that can affect your gameplay. There are other unfavorable rules. Below is a table comparing the effects of rule changes on blackjack house edge, either for better or worse.

Rule	Effect
3:2 payout	Better
6:5 Payout	Worse
Dealer stays on a soft 17	Better
Dealer hits a soft 17	Worse
Double after split	Better
Late surrender	Better
Continuous shuffle machine	Prevents card counting; negligible (~0.02%) effect on house edge, but speeds up play (more hands-per-hour means more money for the casino, which means you’ll lose more money per hour)

Conclusion

6:5 blackjack is not a favorable table, no matter how casinos try to market it. It costs players more. Therefore, ensure you check the table’s rules before sitting down and placing a wager. Watch out for markings on the felt and table signage to see what a table pays. But if you can’t find a clear note on what the table pays, ask the dealer. A few seconds spent reading the table sign or making inquiries can save significant money over the course of a session. The easy way out is to play at the 3:2 blackjack table at all times.
