Store description excerpt
Build sharper blackjack decisions through structured practice and clear probability analysis. Blackjack 21 IQ is an offline learning tool that helps you understand hit, stand, split, surrender, and one-card-then-stand decisions. Each training hand focuses on card play—there is no in-app economy or rewards. FEATURES • Basic-strategy guidance adapted to current practice rules • Dealer bust probability and win/push/loss estimates • Decision-value comparisons for available actions • Flexible deck, soft-17, split, resplit, and surrender rules • Persistent practice history and performance stats • English, Simplified Chinese, and Japanese • Fully offline: no account, ads, tracking, or purchases Probability and decision-value figures are educational estimates based on the cards remaining in the training deck and the assumptions shown in the app. They do not guarantee outcomes.
