Our 5 Top Tips for Blackjack

Blackjack is a game of chance and skill, so having a few tips in your back pocket is always helpful. Whether it’s managing your bankroll efficiently, counting cards or understanding odds a bit better, our pro blackjack tips will help you improve your game and overall experience. Unlike popular luck-based games like roulette and online slots, the options you make when playing blackjack can determine the outcome of the game. Therefore, it is important to keep these handy tips in mind when playing for real money. Let’s get started with our top five tips for playing blackjack.


Understand the House Edge

You’ve probably heard the term ‘house edge’ before, but do you know what it actually means? The house edge is basically a percentage calculated for all casino games at online and brick-and-mortar casinos. The house edge is the casino’s advantage over the player when playing casino games for real money. In blackjack, the house edge is 97-98% if a player is not using a strategy. This basically means that, over time, the house (casino) is likely to gain a profit of 2% to 3% of your stake. That said, players using a strategy could potentially reduce that house edge.

Card Counting

Although card counting is often frowned at when playing at a brick and mortar establishment, it is actually legal and hugely popular and an accepted strategy when playing online blackjack. Counting cards does require some mathematical skill and experience; however, once you have learnt the art of card counting, it can be very helpful when playing blackjack for real money. It helps to tell whether the player or the dealer has the advantage which is based on the residual number of high cards and low cards. With this knowledge, players have a good idea when to raise their bets or lower their bets, resulting in a possibly winning outcome.

Managing Your Bankroll

This may seem obvious and not related to the game at all, but managing your bankroll is probably the most important tip we can give you when playing for real money. If you’re not sure how to manage your bankroll, learn, and learn fast. Our best advice to managing your bankroll would be to start by deciding on a max figure you want to spend before playing any casino game. Once you have reached your maximum, walk away and come back another day. Do not, at any time, spend more money than you can afford with the hopes of earning back on your losses. Also, never bet money you can’t afford to part with.

Managing Your Bankroll

Try Betting Systems

Betting systems, also known as strategies, are popular among blackjack players. The game has inspired several betting strategies over the years, including popular systems such as Martingale. In addition to these betting systems, other strategies exist like splitting. While some players swear by these strategies, others use them to improve their overall experience. That said, no strategy or betting system is 100% effective and while they will help boost your chances of winning, success is never guaranteed.

Be Wary of Insurance

Insurance is a side bet offered when playing blackjack but despite sounding like a good option, is actually not ideal for casual players. In fact, only seasoned players should consider taking insurance and have confidence that the 10s and face cards remain in the deck. Players will need a good understanding of card counting to benefit from insurance.

Using a Betting System

Once you have tried out various betting systems, we suggest you include it as part of your overall and long-term blackjack strategy. There are many systems to choose from, including Parlay, d’Alembert, Martingale and Fibonacci, among others. These systems allow players to play using a set method to decide their next move. As we mentioned, your actions in blackjack could heavily affect the results of the game, so making the right choices are very important here. Alternatively, players can also use strategies to change your game and improve your chances of winning.

Understanding House Edge & Odds

Before you start playing blackjack for real money, it is important to know and understand the house edge. This helps you see how much the casino pays out to its customers. In addition, it is vital to understand your odds when playing and should be one of the first things you check.

While casino games can have a reputation as being rigged, playing at a reputable and trustworthy site means the games will always be fair. Leading online casinos games won’t be unfair in terms of payouts, so you can rest assured that our featured casino sites are all safe and fair. All of the top online casinos are in fact, regularly tested by independent bodies to prove their fairness and safety and that everything is above-board.

They also check that the site offers players the proper odds and that all games are 100% random and unbiased and does not lean towards the house. That said, despite blackjack games being completely fair and random, the nature of gambling means that a player is always at a disadvantage. This is because, when playing blackjack online, there is a house edge of 2-3%, meaning that over time, the house always wins.

The house edge is the average percentage of all bets from players that the casino can expect to keep. This is easy to find at online casinos, but trickier at land-based venues. However, there are ways to improve your chances of winning when playing blackjack online, and that includes using a good blackjack strategy, which can often bring the house edge down to 0.5%. Also check how many decks are in the shoe at each table as this can affect the house edge as well; the more decks in use, the more the house edge increases.

Do I have any advantage over the house?

Since blackjack is a game of chance and skill, you can never accurately predict the outcome of any game, no matter how good your strategy is. While skill and strategy are important, the game is ultimately reliant on luck, which means losing several hands in a row is more than likely. That said, it is possible to increase your odds against the house in various ways when playing blackjack.

Firstly, card counting can really be an advantage if you learn to perfect the skill and could help you lower the house edge significantly. That said, counting cards at an online casino can be tricky, especially if you’re not familiar with the software being used. In many games played online, each card is drawn from a full, fresh deck, so there is no way to count cards in these instances. Other times, cards are not drawn from full decks but there is no way to know if the deck has been reshuffled or not. This is actually good as it promotes fair play but not ideal for those hoping to show off their card counting skills.

Alternatively, players can opt for games like ‘late surrender’ that have a lower house edge than other versions of blackjack. But, just learning a basic blackjack strategy can certainly do a lot to lower the house edge, improve your odds and boost your chances of winning. Just remember, most strategies are fine at online casinos but most likely won’t be allowed at land-based establishments.
