Learn blackjack basic strategy and card counting, with the math behind each move. Play complete practice rounds and get feedback on every decision. Compare the expected value of hit, stand, double, split, and surrender, along with bust risk and win, push, and loss probabilities. Your progress measures the choices you make, so a lucky result does not count as a good decision. Set the number of decks, dealer soft-17 behavior, blackjack payout, surrender, doubling, and split rules. Save your own presets, consult a basic-strategy chart for the active rules, or build a hand in the solver. Counting Lab takes you from Hi-Lo card tags to running counts, full-deck countdowns, true counts, and index plays. Count opening hands across a table of up to five players. In Applied Counting, update the running count, convert it to a true count, and choose a play. Each drill states its rule assumptions and shows where you need more practice. Work through interactive lessons, take a mastery exam, or let Daily Coach choose a short review from your past mistakes. The Daily Challenge gives you a new set of decisions each day. Review weak spots in Progress and return directly to a focused drill. Challenge a friend with a hand and compare decisions after they answer. Practice offline on iPhone, iPad, and Mac. No ads or account required. Double Down is an educational strategy trainer: no real money is staked and no wagers are placed.
