Can you legally tilt the odds a bit closer to even in blackjack? Yes—if you learn
hi-lo card counting the right way. In this guide, you’ll get a clear, fact-checked,
step-by-step path to using the system in live or online live-dealer games, plus a real example,
practice drills, and a quick FAQ.

Responsible Play: Card counting with your brain is legal in most US jurisdictions,
but casinos can refuse service. Never use devices or aids—those can be illegal.
Check your local laws and house rules.

What Is hi-lo card counting?

The Hi-Lo is a classic, balanced system that assigns simple values to cards
so you can estimate when the deck favors the player. It’s popular because it’s accurate enough
to beat many games while staying a beginner-friendly method to learn and execute.

How the values work

  • 2–6 = +1
  • 7–9 = 0
  • 10–Ace = −1

Because the pluses and minuses add up to zero over a full deck, it’s called a
balanced system.

Why it helps

  • More small cards out means more big cards left.
  • Big cards (10s, Aces) boost blackjacks and strong doubles.
  • You raise bets when the shoe is rich in big cards.

hi-lo card counting step-by-step

Learn it in small parts, then combine everything at the table.

Step 1: Memorize the values

  • Say the values out loud while you flip a deck face up, one card per second.
  • Goal: Finish a deck in under 30 seconds with zero mistakes.

Step 2: Keep a Running Count (RC)

Add the value of each exposed card as the shoe is dealt. For example, if you see 5, K, 3, A:

  • Start at 0
  • 5 (+1) → RC = +1
  • K (−1) → RC = 0
  • 3 (+1) → RC = +1
  • A (−1) → RC = 0

Keep the RC in your head at all times. Practice by counting down TV hands or apps.

Step 3: Convert to True Count (TC)

In multi-deck games, divide the RC by decks remaining to normalize the count:

  • TC = Running Count ÷ Decks Remaining (estimate to the nearest half-deck)
  • Example: RC = +6 with ~3 decks left → TC = +2

TC is what you use for betting and playing decisions.

Step 4: Size your bets with the True Count

A simple, effective ramp for a $10 table might look like this:

  • TC ≤ 0: $10 (table minimum)
  • TC +1: $20
  • TC +2: $30–$40
  • TC +3: $50–$60
  • TC +4 or higher: $70–$100 (within table max and bankroll rules)

Keep your spread discreet and steady. Spiky bets draw heat and increase variance.

Step 5: Use basic strategy—and a few key deviations

Basic strategy does most of the work. With Hi-Lo, adjust a handful of close calls using TC:

  • Insurance: Take it at TC ≥ +3 (10-rich shoes)
  • 16 vs 10: Stand at TC ≥ 0; hit below
  • 15 vs 10: Stand at TC ≥ +4; hit below
  • 10 vs 10: Double at TC ≥ +4 (if rules allow and you’re comfortable)

Start with these few. Add more only when your speed and accuracy are solid.

Real-life story: My first weekend with Hi-Lo

On my first serious weekend using Hi-Lo in Las Vegas, I found a 6-deck game,
dealer stands on soft 17, double after split allowed, ~75% penetration.
I flat-bet minimums at TC ≤ 0 and used a 1–8 spread above TC +3.

Day 1 ended up +$220 after 3 hours—mostly from two TC +4 shoes where blackjacks
clustered. Day 2 I hit a cold streak and finished −$90 despite perfect counting.
Across 6 hours, I netted +$130. The lesson: your edge appears over time, not every session.
Keeping sessions short, tipping normally, and chatting about sports helped me blend in.

Practice plan that actually works

If you can do a simple count at home, you can do it at the table.
Here’s a 2-week plan (20–30 minutes/day).

  1. Days 1–3: Single-deck speed
    • Flip one card per second and say the RC aloud.
    • Goal: 1 deck in 30 seconds with 0 errors.
  2. Days 4–6: True count estimation
    • Deal 2–6 decks; pause every few rounds to estimate decks remaining.
    • Goal: TC within ±0.5 of correct value 95% of the time.
  3. Days 7–10: Distraction drills
    • Count while the TV is on or music plays.
    • Practice chip handling while maintaining the RC.
  4. Days 11–14: Full simulation
    • Run mock shoes: bet with a ramp and apply 3–5 deviations.
    • Track errors; tighten before adding speed.

Bankroll, risk, and expectations

  • Edge: With solid execution in good games, long-term EV often lands around 0.5%–1.5% of total action.
  • Bankroll: For lower risk of ruin (~5%), many players aim for 100–200 bets. Example: Using $10 units, a $1,000–$2,000 bankroll.
  • Variance: Swings are real. A winning strategy can still lose in the short term.
  • Etiquette: Always follow house rules; tip as you normally would; don’t be disruptive.

Table rules that matter

Game quality affects your edge more than most people think. Favor:

  • Fewer decks (1–2 decks best; 6 decks is common; 8 is worse)
  • Dealer stands on soft 17 (S17 beats H17)
  • Double after split (DAS) allowed
  • Late surrender if available
  • Good penetration (75%+ of the shoe dealt before shuffle)

Common mistakes to avoid

  • Over-betting at low true counts
  • Forgetting to convert RC to TC
  • Adding too many deviations too fast
  • Table hopping quickly or flashing big spreads in heat
  • Ignoring fatigue—errors erase your edge

Quick glossary

  • Running Count (RC): Ongoing sum of card values seen.
  • True Count (TC): RC divided by decks remaining.
  • Penetration: How deep into the shoe the dealer goes before shuffling.
  • Spread: Ratio of your max bet to min bet.

FAQs

Is card counting legal in the United States?

Using only your brain is legal in most US jurisdictions. Casinos can still refuse service or ask you to stop playing. Never use devices or outside aids; those may be illegal.

How long does it take to learn Hi-Lo well enough to play?

With daily practice of 20–30 minutes, most people reach casino-ready speed and accuracy in 2–4 weeks. Keep working on distraction resistance and true count estimates.

Do I need advanced math skills?

No. You need quick addition and division by small numbers (2–6). The system was designed for mental math at table speed.

Can I use Hi-Lo at continuous shuffle machines (CSMs)?

CSMs neutralize counting because cards are constantly recycled. Look for hand-shuffled or shoe games with meaningful penetration.

What bankroll should a new counter bring?

As a rule of thumb, 100–200 units helps manage risk. If your minimum unit is $10, that’s $1,000–$2,000. Adjust for your risk tolerance and table conditions.

Conclusion

The bottom line: hi-lo card counting offers a practical, proven path to a small edge when paired with smart game selection, clean execution, and disciplined bankroll management.
Start with the drills above, add a few deviations, and grow gradually.
