Stop guessing at the blackjack table. Blackjack Strategy Trainer 21 teaches you the mathematically correct play for every hand using proven spaced repetition techniques. Practice hit, stand, double, split, and surrender decisions with instant feedback. WHY THIS TRAINER IS DIFFERENT Unlike other blackjack apps, this trainer adapts to you. The spaced repetition system tracks which hands you get wrong and serves them more often, so you improve faster where it matters most. 3 RULE SETS FOR REAL TABLES Most blackjack trainers only support one rule set.

See the correct play for every dealer upcard at a glance. Hard totals, soft totals, and pairs are all covered. SMART TRAINING FEATURES - Spaced repetition: hands you get wrong appear more often until you master them - Hand-type accuracy breakdown for hard totals, soft totals, pairs, and surrender decisions - Progressive daily goals that grow with your skill level - Daily streaks with Streak Shields to protect your progress - Auto-advance timer for rapid-fire practice sessions LEARN MODE Not sure where to start?
