Introduction

Uston SS (Uston Statistical System) was created by Ken Uston in the 1970s. It’s an unbalanced system that starts at –4×Decks and aggressively targets mid cards.

Theoretical Foundations

  • 1977: Ken Uston publishes his SS method.
  • Base: Initial offset = –4 × number of decks.
  • Focus: Cards 2–7 are highly valued.
  • Requirement: Ability to handle large swings in the Running Count.

“SS gives you the power of a hammer when the deck is full of low cards.”

How It Works

Assign unbalanced values to each card and begin with a negative offset.

Card 5: +3
Cards 2–4, 6: +2
Card 7: +1
Card 8: 0
Card 9: −1
Cards 10–A: −2
Adjust the count to see its effect
