What is Blackjack?
Blackjack is one of the most widely played card games in the world, and the reason is straightforward: it's one of the few casino games where your decisions genuinely change the outcome. A player who knows basic strategy will consistently do better than one guessing randomly.
The premise is clean. You and the dealer each receive two cards. You can see both of your cards and one of the dealer's. Using that information, you decide whether to Hit (take another card) or Stand (stick with what you have). The goal is to have a higher hand total than the dealer without exceeding 21. Go over 21 and you bust — regardless of what the dealer does.
The dealer doesn't make choices. They follow a fixed rule: hit on 16 or below, stand on 17 or above. That predictability is what makes basic strategy possible — you can mathematically determine the right move for any hand combination.
How to play, step by step
- Place your bet — choose your chip value and stake for the hand.
- Cards are dealt — you receive two cards face up. The dealer gets two cards: one face up (visible to you), one face down (hidden).
- Check for natural Blackjack — if your two cards are an Ace and a 10-value card (10, J, Q, K), that's a natural Blackjack. Unless the dealer also has Blackjack, you win 1.5× your bet immediately.
- Decide: Hit or Stand — look at your total and the dealer's visible card, then choose. Hit to take another card. Stand to keep your current hand.
- Keep hitting if needed — you can hit as many times as you like until you stand, bust (go over 21), or reach 21 exactly.
- Dealer plays — once you stand, the dealer reveals their hidden card and hits until reaching 17 or above.
- Outcome — whoever is closer to 21 without busting wins. If it's equal, it's a push (tie) and your stake is returned.
If the dealer busts (goes over 21), all players who haven't bust win — regardless of their hand total.
Card values
| Card | Value |
|---|---|
| 2 through 10 | Face value (2 = 2, 7 = 7, etc.) |
| Jack, Queen, King | 10 |
| Ace | 1 or 11 — whichever keeps you under 22 |
How Aces work
An Ace is worth 11 unless that would cause you to bust, in which case it counts as 1. So if you hold Ace + 7, your hand is 18 (soft 18). If you then hit and draw a 9, your total would be 27 with Ace as 11 — so the Ace drops to 1, giving you 17. This is called a "soft" hand and it's one of the trickier concepts for new players.
What's a "soft" hand?
A soft hand contains an Ace counting as 11. A "soft 17" is Ace + 6. It can't bust on the next hit (because the Ace would drop to 1), which is why some strategy decisions differ for soft hands vs hard hands of the same total.
Payouts
| Outcome | What you receive |
|---|---|
| Natural Blackjack (Ace + 10-value) | Bet + 1.5× bet (e.g. 100 chips bet = 250 back) |
| Win (higher than dealer, no bust) | Bet + 1× bet (even money) |
| Push (tie — equal totals) | Bet returned |
| Bust (your total exceeds 21) | Bet lost |
| Dealer busts (you haven't busted) | Bet + 1× bet |
Natural Blackjack only applies when your first two cards are an Ace and a 10-value card. If you draw to 21 over multiple hits, it pays 1× — not 1.5×.
Basic strategy — when to hit and when to stand
Basic strategy is a mathematically proven set of decisions for every possible player hand vs dealer upcard. It doesn't guarantee wins, but over time it minimises the house edge to around 0.5%. Ignoring it costs you.
Hard totals (no Ace, or Ace counting as 1)
Always stand
- 17 or higher — always stand regardless of dealer card
- 13–16 when dealer shows 2–6 (dealer is in danger of busting)
Always hit
- 8 or lower — you can't bust, always take a card
- 12–16 when dealer shows 7 or higher
Key rule: the dealer's upcard is everything
When the dealer shows a low card (2–6), they're more likely to bust because they must keep hitting until 17. This is when you should stand on weaker hands and let the dealer self-destruct. When the dealer shows 7–Ace, they're strong — you need to hit more aggressively.
Should I worry about what cards the dealer has face-down?
Basic strategy already accounts for the hidden card statistically. The dealer's face-down card is most likely a 10-value (since 10, J, Q, K all count as 10 and make up 4/13 of the deck). When you see the dealer's upcard, you assume they have approximately a 10 underneath — that's the basis of most strategy decisions.
FAQ
What is a natural Blackjack?
A natural Blackjack is when your first two cards dealt are an Ace and any 10-value card (10, Jack, Queen, or King). It pays 1.5× your bet — the best payout in the game. If both you and the dealer have Blackjack, it's a push.
What happens if both the player and dealer bust?
You bust first. The moment your total exceeds 21, you lose your bet — the dealer's hand no longer matters. You can't "un-bust" even if the dealer also goes over 21.
What does the dealer do on exactly 17?
The dealer stands on 17 — that's the rule. They won't hit to try to improve their hand. This is why 17 is a relatively weak dealer hand; they're stuck with it.
Can I split pairs or double down?
Check the current game interface for available actions. Standard Blackjack commonly supports splitting pairs and doubling down — these are covered by the in-game controls when applicable.
Is Blackjack provably fair on Spinomera?
Yes. The deck is shuffled using a server seed combined with your client seed and a nonce. You can verify the shuffle after each hand using the seed information provided.
