Card Counting Trainer
Four counting systems, shoes from one deck to eight, a deal speed you set yourself, and a graded checkpoint every dozen cards or so. All of it aimed at one skill: carrying a number through a stream of cards without losing it.
Getting the most out of this drill
- Pick a system
Hi-Lo and KO are available from your first round; Hi-Opt I unlocks at blackjack level 2 and the level-two Omega II count at level 5. The card values for all four systems are in the tables under the trainer.
- Set the shoe
Anything from a single deck to eight. Six is the default and the shoe the rest of the trainer assumes — one or two decks is the gentler place to start while the tags are new.
- Choose a deal speed
The slider runs from about 1,900 ms a card (Relaxed) down to 450 ms (Lightning), across four labelled bands. Make the deal faster only once your accuracy holds at the current speed.
- Answer the checkpoints
The first checkpoint lands seven to fourteen cards in; after that they come every eight to fifteen cards, and none fires once three or fewer cards are left in the shoe. Only an exact answer keeps your combo streak alive, though a miss by one still pays its consolation XP.
- Add the true count
Switch on true count conversion and each checkpoint asks for a second number: the running count divided by the decks still in the shoe, rounded down to a whole number (2.6 counts as 2). That is the figure that drives bet sizing and index plays.
- Race one deck
Set the Drill chip to Countdown. One to three cards slide off face down, you flip through the rest of the deck against a stopwatch, and you key the final running count. Because some cards are hidden, the count does not end on the system's usual number, so it has to be counted. Five clean runs in a row under 30 seconds move you on from one card a tap to two.
- Read the tray
Set the Drill chip to True count. Each of twenty flashes shows a running count and a discard tray: read the decks left off the tray, divide, and key the true count, rounded down (2.6 counts as 2, −2.6 as −3). The first rung prints the decks left; 18 of 20 moves you on to the tray alone, then to counts below zero, then to the bet this table's ramp asks for at that count. It needs a balanced system, so it is not offered with KO.
- Scan a table
Set the Drill chip to Table scan. The dealer's upcard and three to five two-card hands show for a few seconds, then turn face down where they lie, and you key the count of the cards you saw. A run is ten rounds. Nine exact rounds of ten move the window from 8 seconds to 4, then to 2.5; the last rung asks for one count carried across five rounds.
What the trainer grades
Each checkpoint is scored three ways: whether your running count was exactly right, how far off it was if not, and how long you took to answer.
The end-of-round summary turns that into checkpoint accuracy, an exact/total tally, your average error and your average reaction time — plus a separate true-count hit rate when conversion is switched on.
Reaction time is the number worth watching. In our experience a correct count arrives long before a fast one, and closing that gap is what the faster deal speeds are for.
Which counting system to drill
All four systems are tag tables over the same shoe.
They differ in how much of the deck they track and how much arithmetic they cost you while the cards are still coming.
- Hi-Lo — balanced, +1 / 0 / −1. The classic starting system, and the one the trainer's index plays are written for.
- KO (Knock-Out) — unbalanced, so it skips the true-count division entirely. Its one structural difference from Hi-Lo is that 7s count +1.
- Hi-Opt I — balanced and ignores aces, which buys a little play accuracy at the cost of running an ace side count alongside it.
- Omega II — a level-two count using +2 and −2 tags. The most powerful of the four and the hardest to hold at speed.
Training wheels and pacing
Turn on “show card values” and every dealt card carries its tag beside it — useful for the first shoe or two with an unfamiliar system, and worth switching off quickly.
You can pause mid-shoe to compare your count against the real one, or end a round early and still bank the checkpoints you answered.
A round runs until the shoe is dealt out, so six decks at a steady pace is several minutes of unbroken attention. We'd start with short, frequent rounds rather than one long one.
Deck Countdown marks
A clean run is an exact final count, keyed with the card values hidden. A wrong count records no time, and a best time needs the third clean run in a row.
- SteadyOne card a tap: a clean deck in 45 s or less, three runs in a row.45 s is our own starting target.
- FluentOne card a tap: a clean deck in under 30 s, five runs in a row. It also opens pairs.A mark counters use with a real deck.physical-deck mark
- PairsTwo cards a tap: a clean deck in 20 s or less, three runs in a row.One source, real deck.physical-deck mark
Marks come from physical-deck practice. Tapping a screen is not the same.
Card values for each counting system
Every system is just a tag per rank. These are the exact values the trainer counts with.
Hi-Lo
Balanced, +1/0/-1. The classic starting system.
| A | 2 | 3 | 4 | 5 | 6 | 7 | 8 | 9 | 10 | J | Q | K |
|---|---|---|---|---|---|---|---|---|---|---|---|---|
| −1 | +1 | +1 | +1 | +1 | +1 | 0 | 0 | 0 | −1 | −1 | −1 | −1 |
KO (Knock-Out)
Unbalanced — no true-count conversion needed.
| A | 2 | 3 | 4 | 5 | 6 | 7 | 8 | 9 | 10 | J | Q | K |
|---|---|---|---|---|---|---|---|---|---|---|---|---|
| −1 | +1 | +1 | +1 | +1 | +1 | +1 | 0 | 0 | −1 | −1 | −1 | −1 |
Hi-Opt I
Balanced, ignores aces. Slightly stronger play accuracy.
| A | 2 | 3 | 4 | 5 | 6 | 7 | 8 | 9 | 10 | J | Q | K |
|---|---|---|---|---|---|---|---|---|---|---|---|---|
| 0 | 0 | +1 | +1 | +1 | +1 | 0 | 0 | 0 | −1 | −1 | −1 | −1 |
Omega II
Level-2 counts (+2/-2). Highest power, hardest to run.
| A | 2 | 3 | 4 | 5 | 6 | 7 | 8 | 9 | 10 | J | Q | K |
|---|---|---|---|---|---|---|---|---|---|---|---|---|
| 0 | +1 | +1 | +2 | +2 | +2 | +1 | 0 | −1 | −2 | −2 | −2 | −2 |
Card Counting Trainer FAQ
How many decks should I practice with?
Start at one or two while the tags are still new — the count swings hard enough to be obvious and a round is over quickly. Six decks is the default and a typical casino shoe, so that is where to end up. The slider goes to eight if you want the count to feel slow and flat.
What deal speed should I be aiming for?
Less than you think. Accuracy comes first: stay at Relaxed or Steady until your checkpoint accuracy is consistently high, then make the deal faster by one band and expect accuracy to fall again for a while. Brisk and Lightning exist to push reaction time down once the arithmetic itself has stopped being arithmetic.
Why does it ask for the running count rather than the true count?
Because the running count is the part you actually carry. It is the raw sum of the tags since the shuffle; the true count is that number divided by the decks left in the shoe. Switch on true count conversion and the checkpoint asks for both, so you practise the division under the same time pressure as the count itself.
What is Deck Countdown?
A mode of this trainer for the single-deck drill. One shuffled deck loses one, two or three cards face down; you flip through the rest as fast as you can keep the count, then key the final running count. A wrong count records no time, and a best time needs the third clean run in a row, so a lucky guess cannot set one. The 30-second and 20-second marks come from practice with a physical deck, and tapping a screen is not the same thing.
What is True Count Flash?
A mode of this trainer for the conversion on its own. A flash is a running count and a discard tray for a shoe of four to eight decks. You judge the decks left from how full the tray is, divide the running count by them and key the true count. This site rounds down: +2.6 is +2 and −2.6 is −3. A set is twenty flashes, and every answer feeds your True count rating. The tray is a drawing, not a real one, so it trains the sum and the habit of looking; a real tray still takes practice of its own.
What is Table Scan?
A mode of this trainer for counting hands as they lie on a table, rather than one card at a time. A round is the dealer's upcard and three to five hands of two cards each, off a six-deck shoe. It shows for the rung's window (a bar drains; your first key ends it early), then the cards turn face down and you key their running count. Hit cards and the dealer's hole card are not part of it. Leave the screen mid-round and that round is dealt again, so nothing is graded that you could not see. It is practice: a run pays XP and is not rated.
Can I use this at a real blackjack table?
No. It is a study tool for practising at home. Casinos treat any device that helps track cards as cheating, and Nevada prohibits using one to aid play under NRS 465.075 — which is exactly why the skill worth drilling is the one you can run silently in your own head.
