Top online blackjack games played in the UK

Top Online Blackjack GamesSince the rapid growth of online gaming in the UK, the iGaming industry has grown exponentially beyond recognition, giving rise to new gambling brands that are keen to capitalise on the demand from players.

For blackjack enthusiasts, this rise in online gaming has led to great things, with fierce competition ensuring the market remains innovative and focused on providing the best possible deals and blackjack games to play.

Online blackjack games are all around us, and to find them, you just need to know where you’re looking.

Of course, exactly what you’re looking for will depend firstly, and crucially on whether you’re out to play for fun or for real.

While many online casinos offer both options, via demo modes and real-play, there are also a number of free online blackjack sites, where you can try your hand at an array of different blackjack variants in a risk-free, sandbox environment, before you risk your cash for real.

However, it is worth noting that free blackjack games, like many others, have been banned in the UK unless you are able to verify your age before playing. This rule was brought in to protect underage and vulnerable citizens being exposed to gambling illegally and unhealthily.

Nowadays, online blackjack casinos have an impetus to invest heavily in developing their platforms and partner with multiple software providers, which in turn leads to better gameplay in terms of graphics, game engine, more variants and functionality.

This is a direct result of the competitive nature of the online casino market – with more competition comes the increasing need to stay one step ahead of the competition, and this constant race to the top delivers improvements that are highly beneficial to players.

How do they do this? It’s a question of resources. With the best technical staff, and more money to throw at software providers and game improvements, online blackjack sites are almost exclusively better these days than they were a decade ago.

In the table below is a list of the current top blackjack games being played online in the UK market.

Online blackjack software providers and developer brands

Online Blackjack Software ProvidersIn modern online gaming, online blackjack games are everywhere, and to choose a blackjack site at random, or to respond directly to an ad might seem a tempting option when you’ve nothing better to go on.

After all, if a quick search brings up a casino, aren’t you best just to plump for that option?

In reality, some people do, but the difficulties associated with doing so quickly become apparent when the casino doesn’t live up to your expectations, particularly on the game-front.

The vital point to note is that, in the UK, not all blackjack casinos are equal, and some are more entertaining than others. This often boils down to the fact that the site offers better quality blackjack games a wider selection of titles to enjoy.

With that said, many UK blackjack sites partner with multiple software providers so that they can bring a larger quantity of blackjack game variants to players, including:

  • Playtech
  • NetEnt
  • Evolution
  • Microgaming
  • Real Dealer Studios
  • Relax Gaming
  • Play’n GO
  • iSoftBet
  • Iron Dog Studio
  • Realistic Games
  • Wazdan
  • Betsoft

RNG Blackjack RTP and house-edge explained

Blackjack RTP and House-EdgeOnline blackjack sites across the globe are designed to provide entertainment and fun for customers, but the ultimate end-game is to make money for the gambling operator. Casino games like blackjack are built in such a way that gives casinos an advantage over players to always make money long-term. This is known as the house-edge, or RTP (return to player).

House-edge and RTP are statistical advantages so that casinos always make money by default. This means that when playing at blackjack sites, players are always at a slight disadvantage in terms of outcome.

The difference between RTP and house-edge in blackjack is that RTP is how much money is returned to players in winnings on average if the game is played continuously over a set period of time. Whereas house-edge is the amount of bets that the casino retains as profit.

House-edge and RTP ratios and percentages vary across the blackjack spectrum depending on which variant of blackjack is being played and how many decks or hands are in action.

The house-edge of the most commonly-played variants at UK blackjack sites are as follows:

  • European Blackjack ≈ 0.38%.
  • Single Deck Blackjack ≈ 0.57%.
  • Multi-Hand Blackjack ≈ 0.62%.
  • Atlantic City Blackjack ≈ 0.35%.
  • American Blackjack ≈ 0.5%

Why live-dealer blackjack is so popular in the UK

One of the most popular ways that UK players are enjoying blackjack is at live dealer casinos. Live dealer blackjack has become extremely popular over the past decade because of the thrilling authentic experience the game offers.

Not only is live blackjack an exciting way of playing the world’s most famous card game, but it beautifully combines a land-based experience with online convenience, to deliver a remarkable, interactive environment at any time of day or night.

In the table below, we outline the advantages and disadvantages of playing live dealer blackjack at sites in the UK, compared with generic online variants and brick and mortar blackjack.

Authentic casino experienceHigher minimum bet limits
Live real-time actionLess game variety
