Basis21 vs Blackjack Trainer

Basis21 teaches you the mathematically correct play for every blackjack hand — not general tips, but the exact, EV-optimal decision for the specific rules at your table. HOW IT WORKS • Pick your casino's exact rule set (deck count, dealer soft-17 behavior, doubling restrictions, surrender availability, and more) — Basis21 ships with presets for major casinos and lets you fine-tune any rule. • Drill: get dealt random hands and choose your play. Basis21 grades every decision instantly, shows the correct action and the EV difference if you got it wrong — and with Continue after Hit, you can draw a real card and play the hand one move further instead of stopping at the first decision. • Strategy Chart: browse the full basic-strategy chart for your rule profile, with an EV breakdown behind every cell so you understand why it's correct — not just what to memorize. • Compare: heading to a different casino? Put your usual rules side by side with the table you're about to play — see exactly how many hands change, and by how much, before you sit down. • Track your accuracy over time, see exactly which situations you're weakest on, and drill them directly — with focus modes for your weakest spots, mistakes you've made before, and the genuine close-call hands where the correct play is a coin flip. WHY BASIS21 Off-the-shelf strategy charts assume one generic rule set. Real tables vary — deck count, dealer soft-17 behavior, doubling restrictions, and surrender rules all shift the correct play. Basis21 computes strategy from first principles for your exact rules, so what you drill is what you should actually do at the table. Basis21 is a training tool for education and entertainment. It does not involve real-money wagering, betting, or gambling of any kind, and correct basic strategy narrows the house edge — it does not guarantee winning.

Blackjack Trainer is a blackjack strategy trainer: learn the basic strategy chart for your table rules, then train Hi-Lo card counting. Every decision is graded, explained in plain English, and drilled until it sticks. Every recommendation is basic strategy, the mathematically optimal play for each hand, verified against a reference expected-value engine, not gut feel or folklore. Play practice hands at a first-person table, get instant feedback the moment you act, and learn exactly why a play is right or wrong. WHAT IS BASIC STRATEGY? Basic strategy is the set of optimal decisions for every blackjack hand: when to hit, stand, double down, split or surrender against each dealer upcard. It can't guarantee any single hand, but it is the strongest way to play, and this app makes it second nature through repetition and clear explanations. A STRATEGY CHART FOR YOUR TABLE RULES Correct strategy changes with the rules, and the app adapts: - Dealer hits or stands on soft 17 (H17 / S17) - 1, 2, 4, 6 or 8 decks - Late surrender offered or not Change any of these in Settings and every recommendation and the full chart update to match. The charts assume double after split is allowed. LEARN BY PLAYING - A living practice table with a dealer and a real deck of cards - Instant feedback on every hit, stand, double, split and surrender, with the reason in plain English - "Remember" cards that teach the pattern behind a decision, not just the answer - The full basic strategy chart (blackjack cheat sheet): hard totals, soft totals and pairs, color-coded - Lessons and drill packs built from your own mistakes and lowest-mastery hands - Progress: an accuracy ring, a trend line and a mastery heatmap across every hand and dealer upcard BUILD A HABIT - Daily: ten hands, the same for everyone, one attempt a day - A day streak that allows one rest day a week - A 14-day path through every lesson and drill pack - Your trickiest hand deals first when you return - Optional reminders, off until you turn them on - Share cards for your streak and progress HI-LO COUNT AND SPEED MATH The Count tab trains the Hi-Lo running count and the true count conversion on cards the app deals, with three drills: card by card, a timed deck countdown, and true count conversion. It is skill practice, like a chess tactics trainer, with no way to enter cards from a real table. Speed Math builds quick mental arithmetic: add up a hand before the timer runs out. EDUCATION, NOT GAMBLING This is a study tool, not a gambling app. There is no real money and no virtual currency. There are no chips, no bets, no bankroll, and no payouts: nothing is staked, and nothing is won or lost. You practice decisions and the app grades them, the way a chess tactics trainer grades moves. PRIVATE BY DESIGN Practice works offline. There's no account and no sign-up. Your progress is stored only on your device. Only an optional Pro purchase goes online, confirmed through Apple and RevenueCat under a random anonymous ID, never your name or email.
