What is card counting?

Card counting is a legal strategy used in blackjack to keep track of whether the remaining cards in the shoe are more favourable to the player or to the dealer. It doesn't involve memorising every card — just keeping a simple running tally as cards are dealt.

When the deck is rich in high cards (tens and aces), the player has an advantage: blackjacks pay out more, and the dealer is more likely to bust. When the deck is low-card heavy, the dealer has the edge. Knowing this lets you bet more when the odds are in your favour.

Important: Card counting is not illegal, but casinos are private property and may ask you to leave if they suspect you're counting. This trainer is for education and home play.

The Hi-Lo counting system

This trainer uses Hi-Lo — the most widely used and beginner-friendly card counting system. Every card gets a value of +1, 0, or −1. As each card is dealt, you add its value to your running total.

Count valueCardsWhat it means
+12, 3, 4, 5, 6Low cards left the deck — slightly better for you
07, 8, 9Neutral — no change to the count
−110, J, Q, K, AHigh card left the deck — slightly worse for you
Example: Three cards are dealt — a 5 (+1), a King (−1), and a 3 (+1). Your running count is now +1. Keep adding as each new card appears.

Running count vs. true count

The running count is your raw tally. But in a multi-deck game (this trainer uses 6 decks), a running count of +6 early in the shoe is less meaningful than +6 near the end.

The true count adjusts for this. Divide your running count by the estimated number of decks left in the shoe:

True count = Running count ÷ Decks remaining

How to use this trainer
1
Start in Guided mode — each card briefly flashes its Hi-Lo value as it's dealt, and the running count updates automatically.
2
Switch to Practice mode to hide the count and test yourself after each round.
3
Use the Quiz tab to drill card values in isolation.
4
Study the Basic strategy tab — counting only gives a small edge on top of correct basic strategy.
5
Use Split when you have a pair — the trainer will show both hands side by side. Play Hand 1 first, then Hand 2. Split Aces get one card each automatically.
