Blackjack Strategy Trainer 21

Master Basic Strategy 21

Free · Designed for iPad. Not verified for macOS.

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. This app supports three, so your training matches the exact table rules you may face: - S17: Dealer stands on soft 17 - H17: Dealer hits on soft 17 - ENHC: European No Hole Card FULL STRATEGY CHART Browse the complete basic strategy chart in a color-coded grid. 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: weak hands 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? Structured lessons cover basic strategy from the ground up. Each lesson includes clear rules and detailed explanations so you understand the reasoning behind every decision. CASINO-STYLE PRACTICE Train on an immersive green felt table with realistic playing cards. It feels closer to a real blackjack table than a boring quiz. AVAILABLE IN 8 LANGUAGES English, Korean, Italian, German, French, Spanish, Portuguese, and Romanian. CLOUD SYNC Create an account to sync your progress across devices. Switch phones without losing your stats, streaks, or shields. FREE TO PLAY Download and start training immediately. No subscription required.
