Uston APC: Advanced Point Count System
Keith Uston’s Advanced Point Count (APC), designed for greater sensitivity during mid and late-deck play.
Learn how this point-by-point system works and why it starts at zero to maximize your edge.
Start the Tutorial ↓Introduction
APC was published by Keith Uston in 1977 as a more detailed alternative to Hi-Lo for mid and late shoe phases.
Theoretical Fundamentals
- Year: 1977
- Initial offset: 0 (starts at zero)
- Card weights:
- 2, 8 → +1
- 3, 4, 6, 7 → +2
- 5 → +3
- 9 → −1
- 10–J–Q–K → −3
- A → 0
- Side count of Aces: integrated as 10–A = −3/0
- Goal: maximize sensitivity in intermediate counts.

How It Works
Assign values to each card and divide the Running Count by decks remaining to get the APC True Count.
Card 5: +3
Cards 3–4, 6–7: +2
Cards 2 and 8: +1
Ace: 0
Card 9: −1
Cards 10, J, Q, K: −3
APC True Count = Running Count ÷ Decks Remaining
When Should You Raise Your Bet?
With APC True Count ≥ +2, your advantage grows. Many players bet 1 extra unit for each additional +1.
Manage your bankroll and stay discreet to avoid detection.
