Best Online Blackjack Sites in the UK for 2025

Blackjack is one of the most famous card games in existence, and has become a mainstay in land-based and online casinos. Blackjack’s origins go as far back as the 18th century when during a card game, players would receive a bonus payout for a hand consisting of the ace of spades and a black jack (either the jack of clubs or spades). Over time, the game has evolved with the incorporation of new rules and strategies, especially with the introduction of the modern casino version of the game.

Since their formation in 2011, Videoslots have prided themselves on having a collection of online casino games which blows competitors out of the water. Their blackjack offering shows they are more than capable of backing up such a claim.

As an overall package, it was hard for me to look beyond Videoslots’ blackjack offering. The game selection is outstanding on its own, with 46 titles on offer. When you add in the excellent welcome bonus which is completely compatible with blackjack, it’s easy to see why I liked Videoslots so much.

Since launching in 2020, Mr Vegas has amassed one of the largest online casino game libraries with over 6,000 games. This makes Mr Vegas’ blackjack offering incredibly competitive.

I think Mr Vegas’ blackjack offering is sensational, offering an insane amount of live and RNG (Random Number Generator) blackjack options. The best part is that so many RNG blackjack games have RTPs higher than 96%, meaning the welcome bonus is fully compatible.

LeoVegas has been a top-tier online casino since it launched in 2011. You don’t win awards like 'Best Mobile Operator' and 'Online Casino of the Year' unless you have a world-class platform, so you can rest assured that LeoVegas are a safe bet for online blackjack.

As well as having a good game selection with exclusive titles, I think LeoVegas’ mobile capabilities really set it apart from the rest of the pack. LeoVegas have two amazing mobile apps available for Android and iOS which are highly rated, making them the perfect casino to play online blackjack while you’re out and about.

Grosvenor Casino is a household casino name in both the land-based and online spaces, with over one million active customers. As a specialist in table games, their blackjack selection was always going to be enticing.

Although 30 blackjack games doesn’t seem like a lot compared to other casinos, I couldn’t fault the quality of the titles on offer at Grosvenor Casino - including an exclusive title in the form of Sweet 16 Blackjack. I found the low 5x wagering requirements eye-catching as well, even if blackjack games don’t fully contribute to the welcome offer.

Playzee, owned by White Hat Gaming,  is a highly-rated online casino platform that has been available to players since 2018. Playzee brings the best online casino games to players everywhere, which most certainly includes blackjack.

In addition to having an exclusive blackjack game to play in the form of Playzee Blackjack, I really liked Playzee’s bonus offering - having up to £300 in a deposit match is incredibly useful for online blackjack, although it’s a shame that blackjack only contributes 10% to the bonus wagering requirements.

PlayGrand burst onto the online casino scene in 2013, and have spent the last decade cementing themselves as a dependable online casino brand.

The part of PlayGrand’s offering that I resonated with most strongly was its blackjack game selection. Not only did I think 34 games was an impressive number for RNG blackjack, but it was the range of providers for the games that interested me. As well as the bigger names such as Microgaming and Evolution, PlayGrand also has more niche titles from the likes of Felt and Golden Rock Studios to round out their blackjack selection.

Blackjack games come in all shapes and sizes, so the title of ‘Best Blackjack Game’ is hotly contested. Here’s a selection of some of our favourites that you’ll come across in online casinos.

There are several factors to consider when selecting an online casino for blackjack. 

Blackjack Game Selection

This is an integral part of what makes an online casino the right fit for blackjack. As well as assessing the quality and quantity of the games on offer, we also look at the split between the live casino and RNG blackjack options, in addition to whether you can play any exclusive blackjack games.

Dedicated Blackjack Section

A key element to consider is how accessible an online casino’s blackjack games are. Many casinos will have a specific blackjack tab to house all their games, whereas others will lump blackjack into a generic table game or live casino section.

Recent Blackjack Releases

Although an online casino needs to be well stocked with classic blackjack games, promoting new blackjack releases is equally important. Keeping up to date with new releases shows that a particular casino holds online blackjack in high regard. 

Bonus Compatibility With Blackjack

When we look at a casino’s bonus offering, we take into account the merit of the offer itself, and whether it can be put towards playing blackjack games.
