How to Play Blackjack
Blackjack is a race to 21 against the dealer. Number cards count face value, jacks, queens, and kings count 10, and aces count 1 or 11 - whichever helps you more. Choose your stake with the point buttons, hit Deal, and you receive two cards face up while the dealer gets one up and one face down. From there you can Hit for another card, Stand to keep your total, Double to double your stake in exchange for exactly one more card, or Split a matching pair into two separate hands. Go over 21 and you bust immediately; otherwise the dealer reveals the hole card and must draw to 17, standing on all 17s including soft 17. An ace plus a ten-value card on the deal is a blackjack and pays 3:2. This table uses a six-deck shoe and offers no insurance option - which is no loss, since insurance has a negative expected value anyway.
You start with 1,000 points, and your best points total is what lands on the leaderboard. If you run out, Reset puts you back to 1,000 - but your recorded high score is always the highest total you've ever reached. Points are only a score: they have no value and can't be bought, sold or exchanged.
Strategy Tips
- Learn basic strategy, or lean on the hint button - every hand has one mathematically best play. The built-in hint shows the correct basic-strategy move for a six-deck, stand-on-soft-17 game.
- Always split aces and eights - a pair of aces is two chances at 21, and 16 is the worst total in the game. Splitting turns both into fresh starts.
- Never split tens or fives - 20 is nearly unbeatable as it stands, and a pair of fives is really a 10 that wants to be doubled, not two weak hands.
- Double down on 11 - you can't bust, and roughly one card in three gives you 21. Double 10 against anything except a dealer 10 or ace.
- Respect the dealer's upcard - stand on stiff totals (12-16) when the dealer shows 2-6, because the dealer is likely to bust. Keep hitting those same totals against 7 or higher.
- Stake a fixed fraction of your points - results are streaky even when every decision is correct. Staking around 2-5% of your total per hand keeps a run of bad cards from wiping you out, which is a neat lesson in variance.

Playing Blackjack on PlayVersusAI
Blackjack here is a card game and a probability exercise. The dealer follows fixed rules, you are dealt two cards, and you decide whether to hit, stand, double down or split to finish closer to 21 than the dealer without going over. Aces count as one or eleven, whichever helps.
Your total is kept in points, which are a score and nothing else. There is no real money involved anywhere on this site — no deposits, no purchases, no cash-out, and no way to convert points into anything. Points from Blackjack do not earn XP, badges or daily challenges either. An optional hint system will tell you what basic strategy recommends for the hand in front of you, which is a genuinely good way to learn why the mathematically correct play is so often counter-intuitive.
What's on This Page
- High-score table — highest scores are ranked on the global leaderboard when you are signed in.
- No account required — the full game is playable as a guest, on desktop, tablet or phone.
There is no AI difficulty setting here, because the dealer is not an opponent making choices — it follows fixed rules, drawing to a set total and standing thereafter. The only decisions in the game are yours, which is exactly what makes basic strategy learnable.
Mistakes That Lose Games
- Standing on a low total because you are afraid of busting. Against a dealer showing a high card, hitting a stiff hand is correct far more often than instinct suggests.
- Never splitting or doubling. These are the two plays that shift the odds in your favour. Declining them permanently is the single most expensive habit in blackjack.
- Taking insurance. It is a side option with a negative expected value regardless of what you hold, and basic strategy declines it every time.
- Assuming the next card is "due". The deck has no memory. A run of low cards changes nothing about the next one beyond what card counting can tell you.
Blackjack Questions
Does this involve real money?
No, absolutely not. Points are a score and nothing more. There are no purchases, no deposits, no withdrawals and no way to exchange points for anything of value, here or anywhere else.
What rules does the dealer follow?
The dealer plays by fixed house rules with no discretion — drawing until reaching a set total and standing thereafter. Because the dealer never makes a judgement call, the odds of any given situation can be calculated exactly.
What does the hint button do?
It shows the basic-strategy play for your exact hand against the dealer's upcard. Basic strategy is a solved table for blackjack, so the hint is mathematically the best available decision rather than an opinion.
