Everything the casino hopes you never practice

Count21 deals you real hands and tells you, every time, whether you played them right. Basic strategy, then card counting, until the correct play is automatic.

Card counting, six systems.
Hi-Lo, KO, Hi-Opt I, Hi-Opt II, Omega II, Zen. Running count, true count, and the deviations that matter.
The Illustrious 18.
The index plays that override basic strategy when the count says so. You get told when one applies.
Strategy charts, H17 and S17.
Every cell drillable on its own.
The count display and card tray.
Verify your mental count against the real one. Estimate decks remaining from what's left in the tray.
Any table.
1 to 8 decks, penetration, soft-17 rule, surrender. The conditions you'll actually face.
A house-edge calculator.
Twenty seconds to know whether to sit down.

Cheaper than one bad session.
