Blackjack 21: Strategy Trainer

Choose a mode such as Basic Strategy, Hand Drills, or Timed Quiz to focus your practice. Set table rules and decks, including dealer hits or stands on soft 17, double after split, and surrender options to match your target casino. Play each hand by selecting Hit, Stand, Double, Split, or Surrender and receive instant feedback on correctness. Study the coaching tip or EV breakdown after each decision to understand why the optimal play wins long term. Use Repeat Mistakes or create a custom drill to reinforce weak spots until you hit your accuracy goal. Review session stats and hand-type performance to plan your next training session and raise difficulty when ready.
