History of Blackjack
Blackjack’s origins can be traced back to 17th-century Europe. It evolved from French games like “Vingt-et-Un” (French for “21”). When the game made its way to America, gambling houses offered bonus payouts to attract players, such as a 10-to-1 payout if the player’s hand included the ace of spades and a black jack (either the jack of spades or clubs) — giving the game its current name.
Today, blackjack is a staple in both land-based and online casinos, loved for its mix of strategy, skill, and luck.

Winning Strategies in Blackjack
Blackjack isn’t purely luck. Blackjack strategies play a huge role for blackjack players looking to improve their odds. Smart players reduce the house edge dramatically by making optimal decisions.

- Always stand on 17 or higher.
- Always hit on 8 or lower.
- Split Aces and 8s.
- Never split 5s or 10s.
- Double down when you have 11 against a dealer’s lower card.

Advanced Blackjack Techniques
- Card Counting: Keeping track of high and low cards remaining in the deck to predict odds. Advanced players use the ‘true count’—which adjusts the running count based on the number of decks left—to better assess their advantage and decide when to increase bets or change strategy. More information about advanced techniques like this can be found on dedicated pages of the site.
- Shuffle Tracking: Following groups of cards through shuffles.
- Betting Systems: Systems like Martingale (double your bet after each loss) — risky but popular.
Note: Card counting is not illegal, but it may get you banned from physical casinos. Online blackjack with RNG software or continuous shuffling machines limits the effectiveness of card counting.
Blackjack Odds and Probability
Understanding blackjack odds and probability is key to making smart decisions and improving your chances of winning when you play blackjack online. Every blackjack game has its own set of odds, influenced by factors like the number of decks in play, the specific rules of the game, and the dealer’s upcard. For example, in most online blackjack games, the house edge is around 0.5% when you use basic strategy, but this can change depending on the casino and the variant you choose.
Knowing the probability of certain outcomes, such as drawing a card that will help your hand or busting if you hit, can help you decide whether to hit, stand, double down, or split. For instance, if you have a hand value of 16 and the dealer shows a 6, the odds are in your favour if you stand, since the dealer is more likely to bust. Many online casinos, including Bitstarz Casino, offer tools like probability charts and calculators to help you make the best choices based on the current game situation.
By familiarising yourself with the odds and probabilities in online blackjack games, you can reduce the house edge and make more informed bets, giving yourself a better shot at winning. Whether you’re playing a single-deck game or a multi-deck variant, understanding the math behind the game is a powerful way to boost your results.
Popular Online Blackjack Variants
Different versions of blackjack can slightly alter the strategy required. Here are some of the best online blackjack games you can play:
- Classic Blackjack: The classic card game version with standard rules.
- European Blackjack: The Dealer gets one card at the start.
- Atlantic City Blackjack: Late surrender and favourable splitting rules.
- Spanish 21: No tens in the deck but bonus payouts.
- Live Dealer Blackjack: Live dealer blackjack games are streamed live with real human dealers.
Each variant has different house edges and rules, so players should always check before playing.

- Bust: Going over 21 and losing the hand.
- Soft Hand: A hand with an Ace counted as 11.
- Hard Hand: A hand without an Ace, or with an Ace counted as 1.

Managing Risk and Bankroll

- Avoid insurance and side bets unless you’re a skilled counter.
- Stick to a basic strategy to reduce the house edge.
- Know when to walk away — managing emotional swings is crucial.
Blackjack Bonuses and Promotions
One of the biggest advantages of playing blackjack online is the wide range of bonuses and promotions offered by online casinos. These blackjack bonuses can give your bankroll a significant boost, allowing you to play more hands and increase your chances of winning. Common offers include welcome bonuses for new players, deposit match bonuses, cashback deals, and loyalty rewards for regular play.
Some online casinos also run special blackjack promotions, such as leaderboard competitions or tournaments with large prize pools. For example, you might find a blackjack tournament at your favourite casino with a $10,000 prize pool, giving you the chance to compete against other players for a share of the winnings. These promotions add extra excitement and value to your gaming experience.
To get the most out of blackjack bonuses, always read the terms and conditions carefully. Pay attention to wagering requirements, eligible games, and any restrictions on withdrawing your winnings. By taking advantage of these offers, you can stretch your bankroll further, place more bets, and have more fun while playing blackjack online.

Common Questions About Blackjack
Can you count cards online?
Maybe it is in live dealer blackjack games with limited decks, as these are the only online format where card counting might be effective. Advanced players often use the true count, which adjusts the running count based on the number of decks remaining, to improve their strategy. In RNG-based games with constant shuffling, card counting is ineffective.
What is the best hand in blackjack?
An Ace and a 10-point card (a natural blackjack), paying 3:2 at most casinos. If you are dealt a natural blackjack, you have won the hand unless the dealer also has a blackjack.
How important is strategy compared to luck?
Blackjack mixes both, but using blackjack strategies can significantly improve your odds over relying on luck alone.
