Blackjack Trainer 101 vs Double Down

Blackjack Trainer 101 is a basic strategy trainer. NOTE: This is *not* a Blackjack game, it is a practice aid for learning basic strategy in Blackjack, and it assumes you already are familiar with the basic rules of the game.  Using this app will *not* guarantee winning in real play, but it will help you play the best possible strategies in any situation. Features: • Four learning modes: random hands, soft hands, pairs, and a custom mode: choose any combination of hands to practice (requires paid upgrade). • Customize the house rules: number of decks in the shoe, hit vs. stand on soft 17, doubling rules and surrender • Skill levels: Higher levels concentrate your training on the harder-to-memorize hands • Strategy guide shows all the best moves and highlights the strategy for the current hand and dealer card • Hint button shows a strategic analysis of the current hand • Left-handed and right-handed playing layouts • Many different rule configurations (1-4 decks, dealer hits/stays on soft 17, double after split, early/late surrender)

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. Pro unlocks Counting Lab and table themes. Main play, tutorials, and charts stay free.
