Count21
A clear idea. A little practice.
Count21 teaches blackjack card counting one skill at a time. Seven lessons take you from why counting works through Hi-Lo values, running and true count, basic strategy, deviations and betting concepts — each ending in a ten-question check. Five self-paced drills build fast recall, and a six-deck practice table reviews every decision, separating decision accuracy from whether you won the hand. Inspect the shoe, replay any shuffle seed, and export your hand history. Count21 is an educational simulation: no real-money play, no live-game tracking.
