The revolutionary Knock-Out card-counting system eliminates the mountain of mental arithmetic necessary to win at blackjack. 

The scientifically devised Knock-Out count can be used profitably anywhere blackjack is played: Las Vegas, Atlantic City, Mississippi, riverboat casinos, Native American casinos, internationally, and on cruise ships. 

This third edition, revised and expanded, is now easier to use than ever. Step into the ring and learn to: 

• Implement the abbreviated “K-O Rookie” system or the new “K-O Rad” system (with optimized card-counter’s basic strategy), each powerful enough to yield a player advantage, yet simple enough to be mastered in a few hours. 
• Advance to a professional-level system—the “K-O Preferred”—which performs on a par with the most sophisticated systems on the market. 
• Avoid common casino pitfalls imposed by recent rules changes, including 6-5 blackjack. 
• Win the cat-and-mouse game between the casinos and the players.
