3:2 vs 6:5 Blackjack — Why the Payout Matters More Than Anything

If you only remember one thing about blackjack, make it this: check the felt before you sit down, and if it says "Blackjack pays 6 to 5," walk to the next table. The difference between a 3:2 payout and a 6:5 payout is the single largest rule effect in the game. It dwarfs the number of decks, the soft-17 rule, surrender, resplits, and any basic-strategy mistake you are likely to make. A player on a 6:5 table loses money faster than almost any other gambler on the floor. Here is why.

What the payout actually means

A "blackjack" or "natural" is any Ace plus a ten-valued card on your first two cards, before any action. When the casino pays for it is what this rule governs:

• 3:2 (or "3 to 2") — for every $10 bet, you win $15 on a blackjack. The traditional and fair payout.
• 6:5 (or "6 to 5") — for every $10 bet, you win $12 on a blackjack. You get $3 less than the traditional payout on the same hand.
• 1:1 (or "even money") — you win only your bet back. Offered as a "choice" on blackjack when the dealer shows an Ace. Mathematically identical to a 6:5 downgrade of the entire game. Always decline. (See our insurance post for why.)

The math

A natural blackjack happens about 4.75% of the time (once every 21 hands, roughly). On a 3:2 table that pays 1.5x, every $100 bet over those blackjacks is worth $150 — a $50 premium for the 3:2 structure. On a 6:5 table paying 1.2x, the same $100 bet pays $120 — only $20 premium. You lose $30 of equity for every $100 bet on hands that happen 4.75% of the time.

Net effect: the 6:5 payout rule alone adds roughly 1.39% to the house edge compared to the same game with a 3:2 payout. A standard 6-deck, S17, surrender, peek game with 3:2 is about 0.42% house edge. Flip the payout to 6:5 and it becomes 1.81%. Roughly four times more expensive to play — same rules otherwise.

Why casinos prefer 6:5

Casinos have been phasing in 6:5 payouts, especially on single-deck tables, for the last two decades. The reason is simple: most recreational players do not notice or do not understand. The table sign saying "pays 6 to 5" looks similar enough to "pays 3 to 2" that tourists gloss over it. A single-deck game with a 6:5 payout is one of the worst bets on the casino floor, significantly worse than American roulette, despite single-deck sounding generous.

The 6:5 rule also interacts with the "blackjack is the most skill-based casino game" narrative. Players come to blackjack tables believing correct play matters. It does — but none of it matters enough to overcome the 1.4% edge the casino steals with this one payout change. Perfect basic strategy at a 6:5 table still loses a lot. Mediocre basic strategy at a 3:2 table loses less.

How to spot the payout

Every blackjack table has the payout printed on the felt, usually near the center or on the betting area. It will say one of:

• "Blackjack pays 3 to 2" — safe, play here
• "Blackjack pays 6 to 5" — do not play
• "Blackjack pays even money" — the worst of the three, rare but it exists

Some casinos use color: dark felt with gold lettering usually means 3:2, red felt often means 6:5, but do not trust color alone. Read the words. If there is no sign or the sign is ambiguous, ask the dealer before you buy in. They will tell you truthfully — it is not a secret.

The "single-deck 6:5" trap

In Las Vegas, Atlantic City, and a growing number of regional properties, single-deck games now almost always pay 6:5. A single-deck 3:2 game would be slightly player-favorable on basic strategy alone — counters could crush it — so casinos compensate with the payout downgrade.

A single-deck 6:5 game is worse for the player than a six-deck 3:2 game. Your instinct to seek single-deck is correct under the old payout structure but completely wrong under the new one. Read the felt, not the deck count.

What to actually do

1. Before you sit down, read the blackjack payout printed on the felt.
2. If it says 3 to 2, you are at a playable table.
3. If it says 6 to 5 or anything else, politely move to another table.
4. Only after you have confirmed 3:2 should you start comparing other rules (decks, S17/H17, surrender).

If the whole casino's tables are 6:5 — and this happens more often than it used to, especially on the Strip — the correct move is to leave and go somewhere else. Most cities still have at least one casino offering 3:2. The drive across town saves more money than any strategy trick.

For the full math on house edge across every rule combination — S17 vs. H17, resplit rules, surrender, peek, you name it — Humble & Cooper's The World's Greatest Blackjack Book has the clearest treatment in one volume. Don Schlesinger's Blackjack Attack is the technical reference if you want exact edge numbers per rule change.

The takeaway

The blackjack payout is the first filter. 3:2 or don't play. Everything we cover about basic strategy and counting and rule shopping is a rounding error compared to this one decision. If the felt says 6:5, no amount of correct play will save you. Read the table, walk past the tourist traps, and save the mental energy for games that will actually pay you fairly when you get a natural.
