Blackjack comes in many variations, and one of the most important differences is how a natural blackjack is paid. You will often see tables listed as paying 3:2 or 6:5, and that small detail has a clear effect on long-term returns.
Understanding these two payout rates helps you choose tables that suit your budget and expectations. Rules that look similar at first glance can produce noticeably different results over time.
This blog post explains what 3:2 and 6:5 mean, how they influence odds and RTP, and which extra rules often come with 6:5 tables. Along the way, you will see straightforward examples so you can compare the numbers at a glance.
Read on to learn more.
What Does 3:2 Mean For Blackjack Payouts?
A 3:2 payout means a natural blackjack pays 1.5 times the original bet. For example, a £10 bet returns £15 in winnings, plus your £10 stake.
This is widely recognised as the standard payout. Its main benefit is simple: natural blackjacks are worth more, which helps keep the house edge lower than formats that pay less for the same hand. Over a longer run of play, that smaller house advantage can make a noticeable difference.
If you like the sound of that, the next question is obvious: what changes at 6:5?
What Does 6:5 Mean For Blackjack Payouts?
A 6:5 payout means a natural blackjack pays 1.2 times the original bet. With a £10 stake, a winning blackjack pays £12, plus your £10 back.
That is a smaller return than 3:2, and the gap adds up over time. The table may look the same, but paying 6:5 increases the casino’s advantage and lowers what you receive on the best hand in the game. Always check the payout printed on the felt or shown in the game rules before you start.
With those basics in mind, it helps to compare how the two ratios affect the numbers behind the game.

Comparing Odds: 3:2 Versus 6:5
The odds describe how often certain events are expected to occur. A natural blackjack appears roughly once every 20 to 21 hands in multi‑deck games. When that hand pays 3:2 instead of 6:5, each occurrence returns more value to the player, so the overall odds tilt slightly more in your favour.
Switching from 3:2 to 6:5 does not change how often a natural blackjack is dealt, but it does reduce what it pays when it arrives. That single rule change is enough to shift the balance of returns across a session.
To see how that shift shows up over the long run, it is useful to look at house edge and RTP.
How Do 3:2 And 6:5 Affect House Edge And RTP?
The house edge is the casino’s built‑in advantage, averaged over many hands. Return to Player (RTP) is the flip side, showing the percentage of stakes a game is expected to pay back in the long term.
- At many 3:2 tables with common rules and basic strategy, the house edge is often around 0.5% (about 99.5% RTP).
- Changing only the blackjack payout to 6:5 typically adds about 1.4 percentage points to the house edge. That pushes it to around 1.9% in similar conditions, reducing RTP to roughly 98.1%.
Other table rules can nudge these figures up or down, but the direction of travel is consistent: paying 3:2 helps the player more than 6:5. Now let’s translate that into pounds and pence.
How Much More Does 6:5 Cost Players In Real Bets?
On a £10 stake, a natural blackjack pays £15 at 3:2 and £12 at 6:5. That is a £3 difference each time. Over a few hands, that might feel small. Over longer play, it builds.
Using the rough frequency of naturals, a player might expect around 9 to 10 blackjacks in 200 hands. On £10 bets, paying 6:5 instead of 3:2 would return about £27 to £30 less across that stretch, simply due to the payout rule. The rest of your strategy could be identical and the gap would still be there.
If you want to see how these figures are calculated, the next section walks through the nuts and bolts.
How To Calculate Payouts And Expected Value For Both Ratios?
Payouts for a natural blackjack are straightforward multipliers of your stake. Expected value (EV) goes a step further by combining each possible outcome with how often it is likely to occur, giving an average result per bet over time.
Example: £10 Blackjack Payouts At 3:2 And 6:5
To see how payout ratios work, consider a £10 bet with a natural blackjack.
- At a 3:2 table: The payout is £15 (1.5 times the bet), plus the £10 stake returned. Total received: £25.
- At a 6:5 table: The payout is £12 (1.2 times the bet), plus the £10 stake returned. Total received: £22.
This is the key difference that feeds through to EV.
Quick Method To Estimate Added House Edge
A simple way to approximate the impact of 6:5 is to focus on naturals. The probability of a player blackjack in common multi‑deck games is roughly 4.8%. The payout gap is 0.3 units of your bet (1.5 minus 1.2). Multiply 0.3 by 4.8% to get about 1.44%. That is why moving from 3:2 to 6:5 is often said to add around 1.4 percentage points to the house edge.
Which Rules Often Accompany 6:5 Tables?
Many 6:5 tables include other rules that further increase the house advantage. These adjustments can look minor on their own, but together they matter.
A common example is the dealer hitting on soft 17. Allowing the dealer to draw another card on a soft 17 slightly improves the dealer’s average result, which raises the house edge. You may also see restrictions on doubling, such as doubling only on totals of 9 to 11, or limits on splitting and re‑splitting pairs. Fewer splits or reduced doubling opportunities mean fewer chances to press an advantage when the maths supports it.
Some 6:5 games also change deck numbers or use side rules that sound appealing at first glance. In practice, these rarely offset the lower blackjack payout. The best approach is to read the rules sheet or help page and weigh the whole package, not just one headline rule.
How To Spot 6:5 Tables Online Or In A Casino?
In land‑based casinos, the payout is usually printed on the felt near the dealer. Look for wording such as “Blackjack pays 6 to 5” or “Blackjack pays 3 to 2”. If in doubt, ask the dealer or check the table placard.
Online, the payout ratio appears in the game’s info panel, rules section or paytable. Many lobbies also display it on the game tile. If it is not obvious, open the rules before joining the table and confirm how naturals are paid.
Knowing the payout up front makes it much easier to compare tables that otherwise look the same.
What Should Players Know Before Playing A 6:5 Table?
Before sitting down, confirm the payout for naturals and scan the rest of the rules. The lower 6:5 return reduces what you receive on your strongest hand, and restrictions such as the dealer hitting soft 17 or limited doubling can further increase the house edge. Check table limits and the stated RTP for that specific game so you know what to expect.
If you choose to play, set a clear budget and stick to it. Take breaks, keep stakes affordable, and view betting as paid entertainment rather than a way to make money. If gambling starts to affect your well‑being or finances, seek support early. Independent organisations such as GamCare and GambleAware offer free, confidential help.
Understanding how 3:2 and 6:5 payouts work, and how the surrounding rules shape the game, puts you in control to pick the tables that best fit your goals and your spend.
