Blackjack Strategy Trainer is your complete blackjack coach: a basic strategy advisor, a card counting trainer, and a realistic casino practice simulator in one app. Learn the mathematically correct play for every hand, build Hi-Lo counting speed, then prove both at a simulated blackjack table where every decision and every bet is graded. Master the game of 21 with math, not guesswork.
STRATEGY ADVISOR
Pick your hand and the dealer's upcard and get the correct basic strategy move instantly: hit, stand, double, split, or surrender. Premium unlocks the full deviation matrix (Illustrious 18, Fab 4 and beyond) so you can see exactly when the count changes the textbook answer. It works as the full basic strategy chart made interactive — every cell of the chart served one hand at a time, with the odds behind each move.
PRACTICE QUIZ
Drill random hands and track your accuracy with a chess-style skill rating. Every answer is scored by its real expected value, so hard decisions count for more than easy ones.
CASINO PLAY MODE
The heart of the app: play full hands against the dealer in a simulated casino shoe, with betting, insurance, splits, doubles, and shuffle timing all included. The trainer grades your bet sizing against the true count, because bet spread is what actually beats blackjack. After each session, a report separates skill from luck: what your play deserved to win, what your mistakes cost, and what was pure variance.
CARD COUNTING TRAINER
Learn the Hi-Lo counting system with running count drills, a true count calculator, bankroll tools (risk of ruin, Kelly betting), and a deviation reference table.
GROWTH TRACKING
A rating graph, EV-loss trends, and accuracy by hand type show your progress hand by hand, so you always know what to fix next.
CUSTOM TABLE RULES
Dealer hits or stands on soft 17, double after split, surrender, doubling restrictions, number of decks: set your table's actual rules and every recommendation adjusts to match.
Blackjack Strategy Trainer is a strategy and skill-practice tool. It does not offer or facilitate real-money gambling, and practice results do not guarantee casino winnings.
The strategy advisor and the first course units are free, with no daily limit. A free trial opens everything else — the live table helper, the full course, the deviation matrix and session reports — and a subscription keeps it.
