Casinos are in business to make money and do this quite well. There are a number of what we consider as the best online casinos, some of which offer players a great selection of games and promotions.

However, players should always remember that online casinos have solid plans and strategies in place to ensure their business’ profitability.

What Is a House Edge? 

House edge is also referred to as the house advantage. The simplest explanation of a casino house edge is that the house or casino will always have better odds of winning than you, the player. 

Every casino game is developed with a slight edge to shift the game’s odds in the house’s favour. The house edge is usually a very small percentage, but it lowers the chances of big wins and payouts across all of its games and ensures the casino receives more than it pays out in the long term.

Live dealer roulette is one of the many games by leading providers Pragmatic Play at top UK online casinos.

Let us take an example of house edge using online roulette: 

On inspection of the European roulette wheel and table, you’ll see that there are 37 numbers between 0 and 36, with the American roulette wheel having 38 numbers with the addition of 00. 

The highest possible actual odds for a straight bet in European roulette are set at 35:1, while these are set at 37:1 for American roulette. Each variant’s table layout hints at the true odds of winning being 37-1 or 38-1 for European and American roulette, respectively. The house’s edge is slightly different between the true odds and the actual odds paid out.

The online casino house edge on a game of American Roulette is 5.26%. So, in theory, for every £100 bet, the casino can count on profits of about £5.26. This doesn’t seem like much for individual punters, but these amounts can rise up considerably when considering numerous players each placing their bets.

The casino house edge on some games is relatively low, sitting at around 1-2%, but it can get up to 25% on others. This percentage represents the casino’s profits and lets them know how much they can reliably expect to earn from each game. 

Knowing which games have the lowest and the highest house edge is good practice in ensuring that you get the best returns from your casino experience.

Nine Casino Games With the Lowest House Edge in the UK

As we mentioned before, certain games provide the house with a better edge than others, so it makes sense to avoid those games and stick to the ones with the lowest house edge possible. 

We’ll check out some of the casino games with the lowest online casino house edge below. Remember that the table games’ figures are based on a player playing a perfect hand and betting strategy.

UK Casino GameHouse Edge
Video Poker0.46%
Blackjack (Single Deck)0.5%
Craps1.4% – 5.0%
Three-card Poker1.5%
Slots2.0% – 10.0%
Hold’em Poker2.36%
European Roulette2.5%
Pai Gow Poker2.5%

You’ll notice that the casino house edge in some games is variable. This variation isn’t due to the casino adjusting the games or anything sinister, but rather the circumstances within the game itself. 

How many card decks are being played, players’ actions in the game, the number of reels and pay ways, the board layout and which betting option you choose can all affect the house edge.

Can you beat the house edge?

Beating the online casino house edge entirely isn’t possible; the casinos are in business to make profits. However, in certain games like poker and blackjack, you can increase your chances of winning by making use of a good strategy, so you can reduce the house edge in games of skill. 

When playing online slots, aside from adjusting your bet amount and paylines, you have very little control over whether you’ll win, so they are truly based on luck. The house edge in slots is higher based on volatility and RTP. 

Let’s get into some of these games, their house advantage, and what you can do to improve your odds below:

Blackjack can be found online in a dizzying array of variations. The number of decks in play and the differences in rules will all affect the house’s edge. 

Being a game of skill, how well you play blackjack is based on your knowledge of the game, your strategy, and luck with the cards you receive. The blackjack house edge is generally indicated at 0.5%, but this is based on a standard rules game with a perfectly implemented blackjack strategy. Not many players play a perfect hand every time.

Novice players are likely to face a higher casino house edge simply because without in-depth knowledge of the game, they are more likely to make poor choices that a more experienced player wouldn’t make.

In order to lower the house edge and increase your wins in a game of blackjack, you should:


There are many online roulette variants, with the most common ones played including American, European, and French.

American Roulette has the highest house edge because of the number 00, which doesn’t appear in the European and French games, so it’s a better option to opt for those game variants that come in at 2.7% for the house edge.

Being a game of chance, your options for reducing the house’s advantage in a game of roulette are limited. Even if you’re well versed in the rules and know the ins and outs of the game, in the end, your bet’s failure or success is down to a simple choice of a number and bet type. 

There are many roulette strategies out there like the Martingale or the Reverse Martingale that can help you win more often and end on a profit.

To better your chances in a game of Roulette, you should:

Video poker

Online poker is available in a wide variety of themes and variants online. The difference between video poker and real-world poker is that you place bets against the virtual dealer, not other players. 

Here, your game prowess can improve your chances of winning and lower the house odds. Playing a perfect game and making the right calls will help you to cash in on that low house edge of just 0.46%.

You can raise your win rate and lower the house edge if you:


Baccarat often lags in popularity with casino users because of the higher stakes in the game. Low-stakes punters tend to stay away from this game.

However, the gameplay here is fairly straightforward, with a house edge of as little as 1.01%. So while the stakes are high, an RTP of close to 100% could be worth giving it a try.

The house edge varies in baccarat depending on the bet you make and the number of decks being played. If you look into the three betting options of backing either the player, the bank or a tie outcome, no matter how many decks are played, backing the house always carries the lowest house advantage of between 1.01 – 1.06%.

Analysis of the game shows that you can increase your chances of winning by implementing a useful baccarat strategy.

This includes some of the following approaches:


Unlike with the games of skill, all online UK slot players are on even footing, relying on the luck of the spin for a win. The payouts on these games are linked to the number of paylines, the size of the bets and the RTP. 

A random number generator or RNG determines the results in a game of slots. Your actions in the game can’t change the RNG, but the size of your bet can lead to bigger payouts when playing games with progressive jackpots. Making smart decisions is the only way to improve your odds of winning playing slots.

Making good choices when playing slots is key to improving your chances of winning.

Conclusion – The House Always Wins?

House edge is a concept that was invented from the start of early land-based casinos started, and over the years it has been honed into a perfect tool for ensuring that the casinos stay profitable and in business. 

Playing online casino games can be quite entertaining and exciting, but since the house edge is always set in the casino’s favour it is not a reliable way to earn an income in the long run. 

Keeping a level head and accepting that online casino games are mainly based on luck will go a long way to more productive play. Do keep out for great promos and offers, and while you may never beat the house edge, implementing the above strategies and gameplay techniques can definitely take some edge off.
