Let’s see how 3:2 vs 6:5 blackjack versions compare so you know what to choose to reap the highest profits.

6:5 and 3:2 Blackjack Rules Explained

6to5 and 3to2 blackjack rules explained

Both games are available at Irish online casinos, but their rules differ, so you should know all the details. In essence, what differs is the payout gamblers receive when they’re dealt or construct a blackjack hand with 21 points.

Before you choose to play any variant, be sure to revisit the basic rules of blackjack, including card values and payout odds.

Beating the dealer’s hand with cards that sum up to less than the 21 maximum results in a 1:1 payout. This means that the paid amount matches your initial bet. In the less likely event of getting cards that sum up exactly to 21, you get a slightly higher payout.

More than informing you regarding the money you receive in this situation, the two rule variations directly play into another theoretical aspect of these table games.

Payout rules affect the house edge

The two games have different payout rules for blackjack hands. That affects the house edge in the sense that the casino will receive more money from Irish bets in blackjack 6:5.

3:2 vs 6:5 blackjack based on house edge

3to2 vs 6to5 blackjack based on house edge

Most players take it as a fact that blackjack pays 3 to 2. With the correct variant, a 21 indeed pays 3:2, while the game generates a 0.411% house edge.

The newer 6:5 version, favoured by gambling operators, increases the house edge up to 1.770%.

Rules for the standard version
  • The game uses eight decks.
  • You can double on any two cards.
  • It has late surrender.
  • It allows no resplits.
  • The dealer stands on soft 17s and peeks for blackjacks.
  • There is no Charlie bonus.

What it means for your funds

What the house edges indicate is that, in a 3:2 blackjack game, the casino is expected to keep 0.411% out of your total wagered funds. If you bet a total of €100, the casino will (theoretically) profit by €0.411.

With 6:5 payout rules, the operator will expectedly keep €1.77 from the same sum.

How do 6:5 rules influence the house edge?

The rule adds 1.359% to the standard house advantage. Keep in mind the house edge we present is only relevant when using the basic strategy

House advantage effects range per rule type

Rule type Effect range Best case Worst case
Number of decks -0.547% to 0% One deck Eight decks
Doubling +0.093% to +0.175% Double on any 2 cards Double on hard 10-11
Surrender -0.558% to +0.077% Full early surrender No surrender
Resplits -0.055% to 0% Resplit up to 4 hands No resplits
Double after split 0% (standard)
Hit split aces 0.19%
Resplit aces -0.125% to -0.105%
Dealer soft 17 0% to +0.199% Dealer stands on s17 Dealer hits on s17
Dealer peeks 0% to +0.109% Dealer peeks for BJ Dealer does not peek
Blackjack’s payouts -2.268% to +2.268% Blackjacks pay 2:1 Blackjacks pay 1:1
Charlie bonus -0.01% to 0% 7-card Charlie No Charlie bonus
Can’t split 4s, 5s & 10s +0.003%

Beyond the basic strategy, applying composition dependent exceptions lowers the house advantage by 0.002%

3:2 Blackjack Provides Better Odds for Players

3to2 blackjack provides better odds for players

You should pick the version that improves your chances for success, and, statistically speaking, the 3:2 blackjack versions is superior.

3:2 blackjack games have the better house edge (sometimes presented as its reverse, the return to player rate) and thus provide better chances to keep your balance, at least.

2:1 blackjack payouts

Variants where blackjacks are paid at 2:1 are the best as they generate a negative expectation on the part of the operator. If a casino provides such a blackjack version, it may encounter a negative balance at the end of the day. With the rules presented above, the 2:1 blackjack house edge is -1.857%.

Always check for 3:2 blackjack

Thus, the nature of your table games and their house advantage becomes an additional criterion of choice for your platforms.

When covering Irish casino bonuses, we stress the fact that table games are often excluded from promotional play. There’s a better scenario where operators allow players to play these games but lower their wagering contribution to less than 100%. This restriction will mean that only a fraction of the total of your wagered money will contribute to the bonus rollover.

Most frequently, table games have wagering contribution percentages range from 10% to 20%.

No deposit bonuses on sign up may exclude these games entirely. Read the terms and the specifications we provide before opting in.

A lower contribution will mean more expenses during turnover. Thus, the funds you can recover by playing become important in the long run.

Casinos Prefer 6:5 Blackjack

Casinos prefer 6 to 5 blackjack

Online casinos naturally prefer you playing blackjack 6:5 since it can generate a better house edge and, thus, more revenue.

Conversely, the 6:5 payout rule is detrimental to the player. Operators will try to balance it out by adding other preferential regulations that would lower the house advantage. However, these efforts are doomed to fail due to one fact, namely, the payout rule’s effect on blackjack’s theoretical house advantage.

The second most effective rule variation revolves around the blackjack surrender option. To make a long story short, early surrender for all cards provides the highest decrease in casino advantage.

Another mistake

One common misconception around 6:5 payouts is that they are larger than those from 3:2 blackjack.

This comes from the apparent difference between the numbers expressing the payouts. However, both rules are expressed in the form of ratios. Once you simplify them, you can see how you get fewer funds for blackjacks.

3:2 vs 6:5 blackjack payouts simplified

Alternate expressions 6:5 3:2 Non-blackjack win
Simplified ratio 1.2:1 1.5:1 1:1
Payouts for €1 €1.2 €1.5 €1
Payouts for €5 €6 €7.5 v5
Payouts for €10 €12 €15 €10
Payouts for €50 €60 €75 €50

3:2 vs 6:5 blackjack payouts by bet size

3:2 vs 6:5 blackjack payouts by bet size

The linear increase of the differences in payout for higher bets is explainable by the way 3:2 and 6:5 blackjack payouts work. The funds you receive always depend on the wager you have placed. For each €1, you get €1.2 in 6:5 blackjack and €1.5 in 3:2 blackjack.

The discrepancy between the two payouts amounts to 0.3 times your bet. For €1, this only amounts to €0.3 less for 6:5 blackjack. In the case of €10, the difference grows to €3, while, for a whopping (and inadvisable) €100, 3:2 blackjack games would make €30 more for a 21 hand.

3:2 vs 6:5 Blackjack – 3:2 Blackjack Wins

3 to 2 Blackjack wins

3:2 blackjack is preferable because your payout odds are better. No matter how hard would casinos try to push the 6:5 version, you should always pick 3:2.

No other rules ad conditions take such a toll on the operator’s advantage against the participating players. You really have no reason to choose blackjack 6:5.

Unfortunately, there may be situations where you have no other choice. Given the current developments around brick-and-mortar casinos, this could soon be a reality for physical gambling venues. Live casino sites can afford to host considerably more game rooms, so they will probably always have 3:2 blackjack options.

Nonetheless, specific approaches can help with both game types, regardless of the payout.

What applies to both

  1. Learn the odds in blackjack and basic strategies charts to increase your chances. These will apply to both types.
  2. Read casino reviews before registering with any platform. Pay extra attention to the table game titles featured on it.
  3. Always check for welcome bonuses and if playing table games with these promotional funds is possible.
  4. Pay attention to other rules that can give you an edge. The number of decks in play is essential. Hence, learn about double deck blackjack.
  5. Blackjack insurance bets are generally useless, giving you no advantage. Learn why and try to avoid it.
  6. Try to learn betting systems like the Martingale strategy. Use them only once you understand their limitations.
  7. Control your betting and keep playing responsibly and consciously. The most important game is played beyond the felt table.
