TwentyOne is a clean, focused blackjack basic-strategy trainer. Learn the mathematically correct play for every hand, then drill it until it's second nature — in a calm, minimalist interface with no ads and no clutter.
WHY TWENTYONE
Basic strategy is the proven, optimal way to play every blackjack hand. TwentyOne doesn't just show you a chart — it computes the correct play for your exact table rules and helps you commit it to memory through fast, focused practice.
THE STRATEGY CHART
• The complete chart for hard totals, soft hands, and pairs
• Color-coded for Hit, Stand, Double, Split, and Surrender
• Tap any cell to see the expected value behind every option
• Recomputes instantly when you change the rules
PRACTICE THAT STICKS
• Deal a hand, choose your action, and see the correct play right away
• Modes: Random, Hard Totals, Soft Hands, Pairs, and Most Missed
• "Most Missed" automatically resurfaces the hands you get wrong
• Track your accuracy, streak, and performance by hand type
PLAYS BY YOUR RULES
Real tables differ, and so does correct strategy. Configure:
• Number of decks (2, 4, 6, or 8)
• Dealer hits or stands on soft 17 (H17 / S17)
• Double after split, double rules, and late surrender
• Resplit aces, hit split aces, and more
The chart and every practice answer adjust automatically.
