Practice perfect basic strategy!
Make the correct decision for each hand based on basic strategy. Wrong moves end the hand immediately.
Basic strategy is the mathematically optimal way to play every hand in blackjack. Developed through computer simulations of millions of hands, it tells you the best decision — hit, stand, double down, or split — for every combination of your cards and the dealer's upcard. Playing perfect basic strategy reduces the house edge to as low as 0.5%, making blackjack one of the best games in the casino.
Each round, you're dealt a hand against a dealer upcard. Choose your action — hit, stand, double, or split — and the trainer instantly tells you whether you made the correct play according to basic strategy. Wrong decisions end the hand so you can learn from the mistake and move on. Track your accuracy with the built-in score counter and aim for a perfect streak.
Always hit hard totals of 8 or below. Hit hard 12 against a dealer 2 or 3. Hit hard 13–16 when the dealer shows 7 or higher.
Stand on hard 17 or higher. Stand on hard 13–16 when the dealer shows 2–6. Stand on soft 19 (Ace-8) or higher.
Double on 11 against any dealer card except an Ace. Double on 10 when the dealer shows 2–9. Double on 9 when the dealer shows 3–6.
Always split Aces and 8s. Never split 10s or 5s. Split 2s, 3s, 6s, and 7s against a dealer 2–7.
Most casual players give the house an edge of 2–5% by relying on gut instinct. Basic strategy cuts that to roughly 0.5%. Over hundreds of hands, the difference is significant. Whether you play at a casino or online, knowing basic strategy is the single most impactful skill you can learn. This trainer helps you internalize the correct plays so they become second nature at the table.
Blackjack is a card game where you compete against the dealer, not other players. The goal is simple: get a hand total closer to 21 than the dealer without going over. If your total exceeds 21, you "bust" and lose immediately, regardless of what the dealer has.
Number cards (2–10) are worth their face value. Face cards (Jack, Queen, King) are each worth 10. Aces are flexible — they count as either 1 or 11, whichever benefits your hand more. A hand containing an Ace counted as 11 is called a "soft" hand because it can't bust with one more card.
A "blackjack" (or "natural") is an Ace plus a 10-value card dealt as your initial two cards. It beats all other hands, including a regular 21 made with three or more cards, and typically pays out at 3:2 odds.
Basic strategy is a set of rules that tells you the mathematically best action (hit, stand, double, or split) for every possible hand combination. It was developed by running computer simulations of millions of blackjack hands. Following basic strategy doesn't guarantee you'll win every hand, but it minimizes the house edge to around 0.5% over time — the lowest of any casino table game.
Yes, completely free. There are no sign-ups, no paywalls, and no limits on how many hands you can practice. Just open the page and start training.
The trainer uses standard multi-deck basic strategy, which applies to games with 4–8 decks. This covers the vast majority of blackjack tables you'll encounter at casinos. Single-deck and double-deck games have minor strategy variations, but multi-deck strategy is the foundation you should learn first.
Yes. Basic strategy applies to any standard blackjack game, whether it's played at a physical casino or online. As long as the rules are standard (dealer stands on soft 17, doubling allowed on any two cards, etc.), the same strategy chart applies.
A "soft" hand contains an Ace being counted as 11 (for example, Ace-6 is a soft 17). It's called soft because you can always take another card without busting — if the next card would push you over 21, the Ace simply becomes a 1 instead. A "hard" hand either has no Ace, or has an Ace that must be counted as 1 to avoid busting (for example, 10-7 is hard 17, and 6-9-Ace is also hard 16). The strategy for soft and hard hands differs significantly.
Yes — this is one of the most important rules in basic strategy. Splitting Aces gives you two chances to hit 21. Splitting 8s turns a weak 16 (the worst hand in blackjack) into two hands starting at 8, which have a much better chance. Even against a dealer's strong upcard like a 10, splitting 8s loses less money on average than playing the 16 as a single hand.
No. Blackjack always has a house edge, even with perfect basic strategy. What basic strategy does is minimize that edge to the smallest possible amount (around 0.5%). In the short term, anything can happen — you can go on winning or losing streaks. Over the long run, playing basic strategy means you'll lose far less than a player who plays by instinct. It's the smartest way to play, but it's not a guarantee.
Most players can learn the core decisions in a few hours of focused practice. Mastering every edge case — especially soft hands and pair splits — typically takes a few weeks of regular practice. Using this trainer for 10–15 minutes a day, most people feel confident within 2–3 weeks. The goal is to make the correct play instinctively, without needing to think about it.
