Blackjack Basic Strategy & EV vs ROY EDGE

Learn blackjack basic strategy with charts, expected values, and focused practice. BASIC STRATEGY CHART Look up hard hands, soft hands, and pairs against the dealer's upcard. Check whether to hit, stand, double, split, or surrender. COMPARE EXPECTED VALUES See the expected value of different actions and compare your options. In practice mode, review action values after answering. ENTER A HAND Select your cards and the dealer's upcard to check the recommended action. DAILY PRACTICE Complete a 10-question daily challenge or practice at your own pace. Track accuracy and streaks as you learn. FOCUS ON YOUR WEAKNESSES Revisit hands you get wrong. Add or remove hands from your weakness list manually, and keep track of the hands you have mastered. HOUSE EDGE CALCULATOR Choose rules such as the number of decks, blackjack payout, and dealer behavior on soft 17. View an estimated house edge and long-term expected loss based on your bet size and number of hands. Estimates do not predict short-term results. The calculator is separate from the strategy chart and does not change its recommendations. ENGLISH AND JAPANESE The interface follows your device's preferred language. Currency can follow your iPhone region or be selected in Settings. Changing currency changes the display, not an exchange rate. LEARNING RESOURCES Review blackjack rules, hand signals, and common terms. The app includes advertising. An optional one-time in-app purchase removes ads. This is an educational tool, not a real-money gambling service. Strategy and expected-value information depend on rule assumptions and do not guarantee winnings.
