Blackjack basic strategy trainer

Random hand, one decision, instant verdict. Every answer is checked against the exact expected value of each action — the same validated engine behind all 340 hand pages — and borderline coin-flips accept both top plays instead of punishing you for a 0.001 difference.

How to use it

Pick a category (or leave All), read your two cards and the dealer’s upcard, and choose Hit, Stand, Double or Split. Wrong answers show the full EV ladder, so you see not just what was right but how much the mistake costs. Buttons that aren’t legal for the hand are disabled, exactly like at a real table, and your best streak is saved in your browser.

What to drill first

Most money is lost in a handful of spots: the stiff hands 12–16 against strong dealer cards, the soft doubles, and the pairs people misplay from folklore — never split tens, always split eights. Run the Hard filter until stiffs are automatic, then Soft, then Pairs. When the drill feels easy, graduate to the full-shoe simulator, where the same decisions arrive wrapped in real dealt hands and a bankroll.
