Card Counting Trainer: Practice Hi-Lo with a Free Shoe Simulator
A free card counting trainer that deals cards from a realistic shoe and checks your running count. Practice the Hi-Lo system with configurable decks, speed modes, and accuracy tracking.

On this page
Practice the Hi-Lo system by tracking the running count as cards are dealt. Check your count at any time to test accuracy. A true count above +2 typically signals a player advantage.
The short answer
The trainer above deals cards one at a time from a shuffled shoe. Your job is to track the running count in your head using the Hi-Lo system. When you're ready, hit "Check Count" and see if you're right. No signup, no paywall, no app to download — just practice.
Key takeaway: Card counting is a skill, not a secret. The Hi-Lo system assigns +1 to low cards (2–6), 0 to neutral cards (7–9), and −1 to high cards (10–A). The running count tells you whether the remaining shoe is rich in high cards (positive count, good for the player) or low cards (negative count, bad for the player). The only way to get fast at it is repetition.
How to use the trainer
- Pick your deck count — 1, 2, 6, or 8 decks. Start with 1 deck until you're consistently accurate, then move to 6 (the casino standard).
- Pick your speed — Manual lets you control the pace. Slow (2s), Medium (1s), and Fast (0.5s) deal cards automatically.
- Track the count — as each card appears, add or subtract from your running count. Low cards (2–6) = +1. High cards (10–A) = −1. Neutral (7–9) = 0.
- Check yourself — hit "Check Count" at any point to enter your count. The trainer tells you if you're right and shows the correct answer if you're wrong.
- Watch your stats — accuracy percentage, current streak, and best streak track your progress over time.
The Hi-Lo system explained
Hi-Lo is the most widely taught counting system because it balances simplicity with effectiveness. Every card that leaves the shoe shifts the count:
Cards | Value | Why |
|---|---|---|
2, 3, 4, 5, 6 | +1 | Low cards leaving = good for you (more high cards remain) |
7, 8, 9 | 0 | Neutral — don't affect the count |
10, J, Q, K, A | −1 | High cards leaving = bad for you (fewer blackjacks and strong hands remain) |
At the start of a fresh shoe, the count is always 0. After every card, you adjust. If you see a 5 (+1), then a King (−1), then a 3 (+1), the running count is +1.
For a full walkthrough of why this works and how casinos respond, read our guide on how card counting really works. The card counting fundamentals lesson covers the same material as part of the blackjack course.
Running count vs true count
The running count tells you the raw balance of high vs low cards dealt. But in a 6-deck shoe, a running count of +6 after 1 deck means something very different from +6 after 5 decks.
The true count adjusts for how many decks remain:
True Count = Running Count ÷ Decks Remaining
A running count of +6 with 3 decks remaining = true count of +2. The same running count with 1 deck remaining = true count of +6. The trainer shows both values when you check your count.
The true count is what actually determines your edge. Most card counters adjust their bet size based on the true count — higher true count, larger bet. The deck count differences article explains why fewer decks amplify the count's power.
How fast do you need to be?
In a real casino, a dealer deals roughly one card per second. A 6-deck shoe contains 312 cards, and the casino cuts off about 25% (penetration), leaving ~234 cards in play. You need to maintain an accurate count through all of them while also making playing decisions.
Practice progression:
- Manual mode, 1 deck — get 100% accuracy at your own pace
- Slow mode (2s), 1 deck — introduce time pressure
- Medium mode (1s), 6 decks — casino-realistic speed
- Fast mode (0.5s), 6 decks — stress test (faster than any real dealer)
Most people need 20–40 hours of practice to count reliably at casino speed. The trainer tracks your accuracy so you know when you're ready to move up.
Does counting work online?
Short answer: not at most online casinos. RNG blackjack shuffles after every hand, making counting impossible. Live dealer blackjack uses a real shoe, but many online casinos shuffle at 50% penetration or use continuous shuffling machines. Our article on counting cards online and the does counting work online lesson cover this in detail.
This trainer is for building the skill itself — whether you use it at a live table, a live dealer online game, or just to understand the math better.
