True Count Trainer
The conversion that turns a raw count into a decision. You are handed a running count and the decks remaining (what the discard tray is there to estimate); divide to get the true count — the per-deck number you actually bet and play off of. A +9 running count is a big edge with one deck left and almost nothing with six. This drills only that conversion, so keeping the count (the Running Count Trainer) stays a separate skill.
Bet 1 unit at true count 0 or below, then add a unit per true count, up to your spread cap.
How the True Count Trainer works
The true count is the running count adjusted for how many cards are left to play: running count divided by the decks remaining. A +9 running count is a strong edge with one deck left but almost nothing with six still in the shoe. That conversion is the single most important piece of arithmetic in counting, and it has to be instant — which is exactly what this drill builds.
Each round hands you a running count and the approximate decks remaining and asks for the true count. You are not counting cards here — that is the Running Count Trainer’s job, and the decks remaining are shown for you on the discard tray. This tool isolates the division so it becomes reflexive. Every answer is graded against exact math, with every standard rounding accepted, and nothing is saved or sent anywhere; it runs on your device.
How to use it, step by step
- Read the scenario. Each round shows a running count and roughly how many decks remain — the two numbers you would have in front of you at a real table.
- Divide. Running count divided by decks remaining gives the true count. A +9 running count with about three decks left is a true count of +3.
- Enter the true count and check. Type your answer; the trainer shows the exact division, the accepted answers, and updates your streak and accuracy.
- Round however you like — consistently. Counters round down, toward zero, or to the nearest whole number. The trainer accepts any standard convention, so pick one and stay with it.
- Hit Next scenario and repeat. Drill it until the division is automatic, with no pause to think.
What you get
- Pure conversion practice — running count and decks remaining in, true count out.
- No dealing, no counting, so the conversion does not blur with the running-count skill it depends on.
- Every standard rounding accepted, with the exact division shown each check.
- Random, realistic scenarios across the full range of counts and shoe depths.
- Live streak and accuracy tracking against exact math.
- Pairs with its siblings — build the count, read the decks, then convert here.
Need to build the running count this assumes? That is the Running Count Trainer. The decks remaining are marked on the tray for you, so you can focus purely on the conversion. And to convert your own numbers on the fly rather than be quizzed, the True Count Calculator is the utility version of this same skill.
Frequently asked questions
What players ask about converting to a true count.
What is the true count?
The running count divided by the decks remaining. It scales the raw count to a per-deck figure, because a +9 running count means far more with one deck left than with six. The true count is what you actually size bets and make deviation plays from.
How does this drill work?
Each round gives you a running count and the approximate decks remaining, shown beside a filling discard tray, and asks for the true count. You divide and enter your answer; the trainer shows the exact math, the accepted answers, and your running accuracy. There is no card dealing — it isolates the conversion.
Why doesn’t it make me keep a running count?
Because that is a different skill with its own tool. Keeping the running count is the Running Count Trainer; the decks remaining are shown to you here on the tray. This drill isolates the division so each piece stays sharp on its own instead of being lumped together.
How should I round the true count?
However you like, as long as you are consistent. Counters round down, toward zero, or to the nearest whole number. The trainer accepts any standard convention and shows you the exact division each time.
How is this different from the True Count Calculator?
The calculator is a utility — you type in your own running count and decks to get the answer. This is a graded drill that quizzes you with random scenarios and tracks your accuracy, so the conversion becomes automatic. Practice on the trainer; compute with the calculator.
Is counting cards illegal?
Counting in your head is not illegal anywhere in the United States — it is a mental skill, not a device. Casinos are private property and can ask a suspected counter to stop or leave. Using a device to count at the table is illegal in most places.
