Start with hard totals, progress through soft hands and pair splitting, and unlock advanced play as your accuracy improves. Every lesson includes strategy charts, detailed explanations, and requires 90% accuracy to advance. You'll know the mathematically correct play for every possible hand. COMPLETE CARD COUNTING COURSE Learn the Hi-Lo system — the same method used by professional advantage players and made famous by the MIT Blackjack Team. Start with 1-deck running count fundamentals and progress to 6-deck true count conversion at full casino speed. Adjustable card speed, tap-to-reveal verification, and accuracy tracking help you build speed without sacrificing precision. THE ILLUSTRIOUS 18 DEVIATIONS Go beyond basic strategy. Learn the 18 count-dependent plays that give you the biggest edge over the house. Most trainers stop at basic strategy — this is where serious players separate themselves. EV CALCULATOR & HOUSE EDGE ANALYSIS Check the exact house edge before you sit down at any table. Input the casino's specific rules and see your expected value. Know whether a game is worth playing before you risk a single dollar. Few blackjack apps offer this — none at this level.
