Hi-Lo Card Counting Trainer is an educational app designed to help you master the Hi-Lo card counting system — the most widely used method in blackjack. Practice across five difficulty levels, track your accuracy over time, and build real casino-ready skills.
The Hi-Lo system assigns a value to each card: low cards (2–6) = +1, neutral cards (7–9) = 0, high cards (10–A) = -1. You keep a running total in your head as cards are dealt. A high positive count means the remaining deck favors the player.
Beginner: 3 seconds per card, 20 cards
Intermediate: 2 seconds per card, 30 cards
Advanced: 1 second per card, 40 cards
Expert: 0.5 seconds per card, 51 cards
Multi-Deck: 2 decks, 104 cards — real casino conditions
The True Count adjusts the running count based on the number of decks remaining. Divide your running count by the estimated number of decks left in the shoe. This gives a more accurate picture of your advantage at the table.
During each session, the app checks your running count 5 times at random moments. Your score is based on how close your answers are to the correct count at each checkpoint.
