How to Play Blackjack

Blackjack is the most player-friendly game in the casino. With the right strategy, the house edge drops below 0.5% — making it one of the rare games where skill genuinely matters. This guide covers everything from the basics to the key decisions that separate winning from losing play.

The Goal

Beat the dealer. That's it. You're not trying to reach 21 — you're trying to finish with a higher hand total than the dealer without exceeding 21. If you go over 21, you "bust" and lose immediately regardless of what the dealer does.

Card Values

Jack, Queen, King10
Ace1 or 11 — whichever helps you more

A hand containing an Ace counted as 11 is called a soft hand. A hand where the Ace must count as 1 (or there is no Ace) is a hard hand. This distinction matters for strategy.

How a Hand Works

You and the dealer each start with two cards. One of the dealer's cards is face up; the other is face down (the "hole card"). You then choose from these actions:

After you stand, the dealer reveals their hole card. The dealer must hit until reaching 17 or higher — they have no choice. If the dealer busts, all remaining players win.

Payouts

Why 3:2 matters: Some casinos pay blackjack at 6:5, which raises the house edge by about 1.4%. At Agena Gaming, blackjack always pays 3:2 — the standard for a fair game.

Basic Strategy — the Key Decisions

Basic strategy is a mathematically proven set of decisions that minimises the house edge. You don't need to memorise every combination — focus on the situations below, which cover the majority of hands you'll encounter.

Hard 8 or less
Always hit
Hard 9
Double if dealer shows 3–6, else hit
Hard 10
Double if dealer shows 2–9, else hit
Hard 11
Double always
Hard 12–16
Stand if dealer shows 2–6; hit otherwise
Hard 17+
Always stand
Soft 17 (A+6)
Hit or double vs dealer 3–6
Soft 18 (A+7)
Stand vs 2,7,8; double vs 3–6; hit vs 9,10,A
Soft 19–21
Always stand
Pair of Aces
Always split
Pair of 8s
Always split
Pair of 10s
Never split — stand

House Edge

Blackjack with basic strategy carries a house edge of roughly 0.5–0.9%, depending on the exact rules. That means for every $100 wagered, the expected long-run loss is under $1. No other game on this site comes close.

Common mistakes that raise the house edge: taking insurance, splitting 10s, standing on soft 17, and playing hunches over strategy. Stick to the table above and you're playing close to optimal.

Frequently Asked Questions

What is the goal of blackjack?
Beat the dealer by getting a hand value closer to 21 without going over. You don't need to reach 21 — you just need a higher total than the dealer, or for the dealer to bust.
What does blackjack pay?
A natural blackjack (Ace + any 10-value card) pays 3:2 at Agena Gaming. So a $10 bet returns $25 (your $10 back plus $15 winnings). A regular winning hand pays 1:1.
When should I double down?
The most straightforward doubles: always double on hard 11, double on hard 10 when the dealer shows 2–9, and double on hard 9 when the dealer shows 3–6. Doubling is powerful because you can capitalise when the dealer is likely to bust.
Should I always split Aces and 8s?
Yes. Splitting Aces gives you two chances to hit 21. Splitting 8s turns a terrible 16 (the worst hand in blackjack) into two separate hands each starting at 8 — a much stronger position.
What is the house edge in blackjack?
With basic strategy, approximately 0.5–0.9%. This makes blackjack one of the best-value games in any casino. Without strategy, the house edge climbs to 2–4%.
What is a "soft" hand?
A soft hand contains an Ace counted as 11. For example, Ace + 6 = soft 17. It's called "soft" because you can't bust on the next hit — the Ace simply becomes 1 if needed.
