Zen Count
Master the Zen Count — a powerful balanced Level 2 system for serious blackjack players. Protocol 21 provides the custom multi-value drills you need to run Zen Count at casino speed.

What is the Zen Count card counting system?
The Zen Count is a balanced Level 2 card counting system developed by Arnold Snyder. It assigns +1 to 2s and 3s, +2 to 4s, 5s, and 6s, 0 to 7s and 8s, -1 to 9s, and -2 to 10-value cards. Aces count as -1. It is more powerful than Hi-Lo but less complex than Omega II, making it a strong choice for serious intermediate players.

History & Origins
Developed by Arnold Snyder (author of 'Blackbelt in Blackjack'), the Zen Count was designed as a middle ground between the simplicity of Hi-Lo and the power of multi-level systems like Omega II. Snyder specifically incorporated Aces into the running count (at -1) so that players do not need a side count, unlike Omega II which tracks Aces separately and requires extra mental overhead.
Zen Count vs. Other Systems
Zen Count vs. Hi-Lo: The Zen Count's higher Playing Efficiency (0.63 vs. 0.51) produces noticeably better index decisions, especially on soft hands and late surrender plays. Zen Count vs. Omega II: Zen Count is slightly easier since Aces are built into the main count at -1, whereas Omega II demands a completely separate Ace side count. For a player who wants to step beyond Hi-Lo without reaching maximum difficulty, Zen Count is the ideal bridge system.
