I
A serious craft.
Finally taught like one.
Six units. Thirty lessons. Nineteen drill types. A casino simulator calibrated to real table rules. Count Dojo is the training ground for players who treat card counting as what it is — a disciplined, legal, learnable skill.
Free to start · No math skill required · Works offline
Act I · The Deal
Thirteen ranks.
Four suits.
One legal edge worth mastering — hidden in the patterns the cards leave behind.
Act II · The Helix
The count lives in
what remains.
Not in the card you just saw. In every card that has not come yet.
Act III · The Edge
The edge is legal.
The work is yours.
The math is simple. Everything below this line is how we teach it.
Demonstration
This is what counting looks like.
Every card has a Hi-Lo tag. Low cards (2–6) add one. Tens and aces subtract one. Sevens through nines are zero. Keep the running total in your head. That is the entire idea. Now watch the count drift as the shoe reveals itself.

Count Dojo teaches this from the first lesson, then accelerates it — through speed flashes, distractions, and the deck countdown drill. Legend tier is a full deck in under twenty seconds.

Epigraph
“Blackjack can be beaten. Not with luck or hunches or betting systems. With mathematics.”
II

IV
Seven systems.
Fluent in one, literate in six.
Hi-Lo is the gold standard and our default. Side branches cover six alternatives — for history, curiosity, and the players who benefit from specialized systems.
Hi-Lo
The gold standard. Taught first, practiced deepest, and the one 99% of players should use.
2-6 → +1 7-9 → 0 10-A → −1
KO
Unbalanced — skips the true-count conversion step. Slight trade in accuracy for simplicity.
2-7 → +1 8-9 → 0 10-A → −1
Hi-Opt I
Slightly more accurate than Hi-Lo at the cost of a separate side ace-count.
3-6 → +1 2, 7-9, A → 0 10 → −1
Hi-Opt II
High ceiling, unforgiving in practice. Side ace-count recommended.
2-3, 6-7 → +1 4-5 → +2 8-9 → 0 10 → −2
Omega II
Highest practical power. For Schlesinger loyalists who lift weights for fun.
2-3, 7 → +1 4-6 → +2 8 → 0 9 → −1 10 → −2
Zen Count
Balanced level-2. Trades simplicity for correlation. Popular in academic circles.
2-3, 7 → +1 4-6 → +2 8-9 → 0 10 → −2 A → −1
Wong Halves
Theoretical perfection, practical nightmare. Included for completeness.
2 → +0.5 3-4 → +1 5 → +1.5 6 → +1 7 → +0.5 8 → 0 9 → −0.5 10-A → −1
V
Where the edge actually lives.
Running count measures what has left the shoe. True count scales it by what remains. Each TC point shifts your edge by roughly half a percent. That is the entire thesis — quantified.
True count formula
Running count of +10 with five decks left behind the cut card is a true count of +2. That +2 is a bet-sizing and deviation signal — one the casino cannot see.
Truncate toward zero. No rounding up.
Edge by true count
6 deck · S17 · DAS
Below zero, the house owns the table. Above zero, you do. The crossover sits just above TC +1 — bet-sizing territory begins there.
VI
A casino, calibrated.
The simulator models the rules that matter: dealer stand, double after split, shoe size, penetration, distractions, surveillance. Your bet sizing, true-count reads, and play decisions are graded in real time.
- H17 or S17 dealer rule
- Double after split
- Resplit aces, late surrender
- 1 to 8 deck shoes
- Configurable penetration (50–90%)
- Realistic chip spreads (1-4 through 1-20)
- Discard tray visualization
- Multi-player AI tables
- Distraction overlays
- Heat and surveillance grading
- Count checkpoints mid-shoe
- Multi-axis performance scoring

Sixty-five ways
to be caught trying.
Some are earned by finishing units, some by hitting speed gates, a few by showing up at strange hours. Centurion is the hundred-day streak. Inhuman Speed is a full deck counted down in under twenty seconds.

X
A short, honest comparison.
Count Dojo is not the only way to learn. It is the only way that treats the stack — curriculum, drills, simulator, and reference — as one thing.
YouTube videos
Scattered. No structure. No progress. No way to grade your running count.
Thorp, Wong, Schlesinger
The canon. Essential reading. A book cannot time your deck countdown.
Drill-only apps
Assume you already know how to count. Skip the education.
Count Dojo
Curriculum, drills, simulator, reference. One stack, from beginner to Grand Sensei.

Every screen.
Nothing staged.
Twenty-seven screens across five surfaces — the curriculum, the drill floor, the simulator, the reference shelf, and the tools you take to an actual casino. Straight from the app, uncropped.
Six units, thirty-plus lessons. Each one teaches a single idea, shows the arithmetic on real hands, then checks that it landed.

“I went from knowing nothing about card counting to being able to count down a deck in 30 seconds. This app is legit.”
“Most apps just assume you already know how to count and give you drills with no actual education. Count Dojo actually starts from zero — and if you don't need it, you can advance faster.”
“Finally, a structured way to learn card counting. No more YouTube videos or books.”
“Went to Vegas last month and felt confident at the tables for the first time.”
XIV
Common doubts, straight answers.
Yes. Completely legal. It is a mental skill; you are keeping track of information already visible to you. A casino can ask you to leave their property, but cannot arrest or charge you.
No. Counting gives you a mathematical edge over time — typically half a percent to two percent at a favorable true count. Variance means short-term losses are normal. You are building an advantage, not a certainty.
Most players finish the foundations in thirty to sixty days with daily practice. Casino-ready performance takes longer — weeks of speed work on the drills, plus focused sessions in the simulator.
No. Hi-Lo only requires adding and subtracting one. True-count conversion is dividing a small integer by another small integer. Every bit of arithmetic is taught step by step.
Free gives you all seventeen lessons of Unit I, the first five lessons of Unit II, five unlimited practice drills, and every reference tool. Premium opens Units II through VI, the casino simulator, personalized practice, and the full nineteen-drill library.
Hi-Lo. It is the best practical balance of accuracy and ease of use, and every serious player's first system. Six other systems are available in the app for the curious or the obsessed.
Yes. Every lesson, drill, and reference tool works offline. Progress syncs to the cloud when you are back online.
