Description
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.
