The KO Count

KO (Knock-Out) removes the hardest part of card counting, the true-count conversion. There is no dividing by decks remaining and no deck estimation. You add one, subtract one, and compare a single running number to two memorized landmarks.

The cost is a little accuracy at the extremes, measured on our comparison page. In return, most people can play KO without errors, which matters more than theoretical power. This course stands alone. You do not need to know Hi-Lo first. Bankroll math, game selection, and cover play are in the Card Counting course and apply to every system.
