How to Play Blackjack

The Goal of Blackjack

The most common misconception about blackjack is that the goal is to get as close to 21 as possible. That is not quite right. The goal is to beat the dealer. You beat the dealer by finishing with a higher total than them without exceeding 21. That distinction matters because it changes every strategic decision you make.

If the dealer is showing a 6 and you have 14, you are not trying to get to 21. You are trying to survive long enough for the dealer to bust. Those are completely different strategic situations, and understanding the difference is the first step to playing correctly.

Card Values

Blackjack uses one to eight standard 52-card decks. Card values are straightforward with one important exception.

The Ace is the most important card in blackjack. Because it can count as 1 or 11, it makes hands flexible. A hand containing an Ace counted as 11 is called a "soft" hand. A hand where the Ace must count as 1 (because counting it as 11 would bust the hand) is "hard."

Example: Ace + 7 = soft 18 (the Ace is counting as 11). If you then hit and draw a 9, your total would be 27 if the Ace stayed at 11, which busts you. So the Ace automatically drops to 1, giving you hard 17.

How a Hand Plays Out

At the start of each round, you place your bet in the betting circle. The dealer then deals two cards to each player and two to themselves. Player cards are both face up. The dealer shows one card face up (the "upcard") and one face down (the "hole card").

You can now see your two cards and one of the dealer's cards. That single dealer upcard is your most important piece of information. Every strategic decision you make will be based on your total and the dealer's upcard. Memorise this concept, it is the foundation of everything.

Once all players have acted (see the decisions below), the dealer reveals the hole card and plays their hand. The dealer follows fixed rules and has no choice in how they play. After the dealer completes their hand, your total is compared against theirs and bets are settled.

Your Decisions

Blackjack gives you more decision-making power than any other common casino game. Each decision directly affects your expected outcome. Here are all the options available to you.

The Dealer's Fixed Rules

Unlike you, the dealer has no choices. The casino dictates exactly how they must play every hand. Understanding these rules is essential because they determine when you should stand and let the dealer take the risk of busting.

The dealer cannot double down, split, or surrender. They play mechanically. This is actually what gives skilled players an advantage: you can make optimal strategic decisions while the dealer is bound by rigid rules. When the dealer shows a bust card (2-6), the correct play is often to stand on low totals and let the dealer destroy themselves.

Basic Strategy: The Optimal Decision for Every Hand

Basic strategy was derived by running hundreds of millions of computer simulations of every possible combination of player hand and dealer upcard. For each combination, the simulation determined which decision (hit, stand, double, split) loses the least money over the long run. The result is a complete lookup table covering every situation you will encounter at the table.

A player using perfect basic strategy reduces the house edge to approximately 0.3-0.5% depending on the specific table rules. That is the closest to even money you can get in any casino game that does not involve skill against other players.

Table Rules That Meaningfully Affect Your Edge

Not all blackjack tables are created equal. Specific rule variations can add or subtract percentage points from the house edge. Here are the ones worth checking before you sit down.

Playing Blackjack at Ontario Online Casinos

Every licensed Ontario casino offers multiple variants of online blackjack. The most relevant for strategy-focused players are the RNG (software) versions and the live dealer versions.

RNG blackjack shuffles after every hand, which eliminates any card counting advantage but also means the game moves as fast as you want it to. You can pause, consult strategy charts, and take your time. For learning, this is the ideal format.

Live dealer blackjack streams a real dealer from a studio. Cards are dealt from a multi-deck shoe (typically 6-8 decks) and are not reshuffled after every hand. The social experience and transparency of seeing real cards make this the preferred format for experienced players.
