Let's be real for a second. If there were a secret button you could press to learn how to always win blackjack, the casinos in Vegas would have been turned into luxury condos years ago. They aren't. In fact, they're busier than ever. Why? Because the "always" part of that sentence is a mathematical ghost. You can't win every hand. You can't even win every session. But you can tilt the floor just enough to stop being the "sucker" the house relies on to pay for their neon lights.
Blackjack is unique. Unlike slots or roulette where the physics are fixed, blackjack is a game of shifting probabilities. The cards already dealt change the odds of the cards remaining. That’s the crack in the armor.
The Math of How to Always Win Blackjack (or Get Close)
Everything starts with Basic Strategy. It’s not a suggestion; it’s a mathematically proven map created by guys like Julian Braun back in the 60s using massive mainframe computers. He ran millions of simulations to find the one move for every possible scenario that minimizes the house edge to about 0.5%.

If you aren’t using a strategy chart, you’re basically donating money. Most players follow their "gut." Their gut tells them to stand on a 12 against a dealer's 2 because they're afraid of busting. The math says that's a mistake. You hit. You take the risk. If you want to know how to always win blackjack over the long haul, you have to play like a machine, not a person with feelings.
Why Your "Hunch" is Killing Your Bankroll
I’ve sat next to guys who swear they "feel" a face card coming. They double down on a hard 12 because they're "due." Statistics don't care about what you're due for. The deck has no memory. The only thing that matters is the composition of the remaining cards.
Most people play what’s called "mimic the dealer" strategy. They hit until they reach 17 and never double or split. This is a disaster. It gives the house an enormous 5.5% edge. By simply learning when to split Aces and 8s—every single time, no exceptions—you slash that edge. It’s boring. It’s repetitive. It’s the only way to play.
Card Counting: The Only Real Way to Flip the Script
We have to talk about the MIT Blackjack Team. You've seen the movies. They didn't have magic powers; they had a system called Hi-Lo. This is the only legitimate answer to how to always win blackjack in a way that actually results in a positive expected value (+EV).
When the deck is rich in 10s and Aces, the player has the advantage. Why? Because the dealer is more likely to bust when they have to hit their stiff hands, and the player is more likely to get a 3:2 payout on a natural Blackjack. When the "count" is high, you bet big. When it’s low, you bet the minimum or walk away to get a drink.
- The Hi-Lo System: You assign a value of +1 to low cards (2-6), 0 to 7-9, and -1 to 10s and Aces.
- The True Count: Casinos use multiple decks (usually 6 or 8). You have to divide your "running count" by the number of decks left in the shoe. A running count of +6 with 6 decks left is just a +1 True Count. That's barely an advantage.
- The Heat: Pit bosses aren't stupid. If you suddenly jump from a $10 bet to $500 when the count is high, you’re getting a tap on the shoulder and an invite to leave.
The Brutal Reality of Variance
You can play perfectly and still lose ten hands in a row. That’s variance. It’s the "noise" that hides the signal. Real pros, people like Don Schlesinger who wrote Blackjack Attack, talk about bankroll management more than they talk about the actual cards.
If you go to a table with $200 and bet $25 a hand, you’re going to go broke. Fast. Even with a mathematical edge, you need a "cushion" to survive the swings. Generally, a professional card counter needs 1,000 "big bets" in their bankroll to avoid a 100% chance of ruin. For a casual player trying to figure out how to always win blackjack, the best advice is to treat your session like a business trip. Set a loss limit. Stick to it.
Avoid the "Sucker Bets"
Insurance is a scam. Unless you are counting cards and know for a fact that the deck is loaded with 10s, never take insurance. It is a side bet that the dealer has a 10-value card under their Ace. The odds are consistently against you.
Same goes for those flashy side bets like "Kings Bounty" or "Perfect Pairs." The house edge on these can be as high as 10% or even 20%. They exist for one reason: to take the money you’re winning at the main game and put it back in the casino's pocket. Honestly, just ignore them. They’re a distraction from the main grind.
Where People Get It Wrong
People think the goal of blackjack is to get as close to 21 as possible. It isn't. The goal is to beat the dealer. Sometimes that means standing on a 13 and praying the dealer busts. It feels weak. It feels like you’re giving up. But if the dealer is showing a 5 or 6, they are in a "bust-prone" position. You don't need a high total; you just need to stay alive while they crash.
Another myth is that the "third base" player (the one who acts last) can ruin the table by taking the dealer's bust card. This is statistically false. While it might feel like that guy ruined your night by hitting on a 15 and taking the 10 the dealer needed to bust, over a million hands, it evens out. Sometimes he takes the card that would have given the dealer a 21. You just don't notice those times because you're too busy being mad about the losses.
Finding the Right Table
Not all blackjack games are created equal. This is arguably the most important part of how to always win blackjack consistently. You need to look for specific rules:
- 3:2 Payout for Blackjack: Many tables now pay 6:5. This sounds like a small difference, but it's massive. A 6:5 payout increases the house edge by about 400%. Never, ever play at a 6:5 table.
- Dealer Stands on Soft 17: If the dealer has to stand on an Ace-6, it’s better for you. If they hit (S17), the house edge goes up.
- Double After Split (DAS): This allows you to be more aggressive with your money when you have the advantage.
- Surrender: Being able to give up half your bet on a terrible hand (like your 16 vs. a dealer 10) is a huge long-term win for your bankroll.
Actionable Steps for Your Next Trip
Stop looking for a "vibe" and start looking at the math. If you want to walk away with more money than you started with, follow this checklist.
First, download a Basic Strategy chart and memorize it until you can recite it in your sleep. Better yet, buy a plastic one at the casino gift shop; most casinos actually let you use them at the table as long as you don't slow down the game.
Second, check the table sign. If it says "Blackjack pays 6 to 5," keep walking. Don't even sit down. Find the 3:2 table, even if the minimum bet is a bit higher.
Third, manage your money. Decide before you walk through the doors exactly how much you are willing to lose. Once that money is gone, you’re done. No "re-buys" to chase losses. Chasing losses is how "how to always win blackjack" turns into "how to lose your car."
Fourth, watch the "penetration" of the deck. If the dealer is cutting off half the cards in a shoe, card counting is impossible. You want a dealer who deals deep into the deck. This is where the real opportunities live.
Fifth, stay sober. The free drinks are the most expensive thing in the casino. Blackjack requires focus and quick mental math. Alcohol blurs the lines and makes you take "fun" bets that ruin your strategy.

Blackjack is a grind. It’s a game of inches, not miles. You win by making fewer mistakes than the person sitting next to you and by capitalizing when the math swings in your favor. It’s not about magic; it’s about discipline. Be the player the casino hates: the one who knows the rules, uses the chart, and walks away when they’re up. That's the only real way to win.
