Counting System Reference
Protocol 21's primary training engine focuses heavily on mastering the Hi-Lo system (the industry standard). Additionally, we provide comprehensive reference material for six other counting methodologies:
Hi-Lo System (Beginner)
The most popular and easiest balanced counting system. Perfect starting point with simple card values and proven effectiveness.
KO/Knock-Out System (Beginner)
Unbalanced count eliminating true count calculation until end of shoe. Ideal for learning without the complexity of fractional true count conversion.
Zen Count System (Intermediate)
More precise than Hi-Lo with side counts for aces. Offers better betting accuracy with moderate complexity increase.
Red 7 System (Intermediate)
Unbalanced count using red sevens as +1. Eliminates true count conversion complexity while maintaining good accuracy.
Omega II System (Advanced)
Fractional counting system with greater precision. Requires side counts for aces and deuces, highest betting accuracy.
Wong Halves System (Expert)
Most complex and precise fractional system ever created. Maximum betting advantage with multiple side counts and fraction values.
