  • Regulation: The UK casino market is super safe. To such an extent. The general public often lambasts its laws as draconian. We won’t go so far, but what is important we see the big picture. Every UK online casino that targets UK residents must have a license from the British Gambling Commission. Therefore, we only work with UKGC-certified UK online casinos. Sites that operate under the UKGC banner are the Alderney Gambling Control Commission, Gibraltar Gambling Authority, and Malta Gaming Authority.
  • Security: When it comes to real money casino games there must be trust. Without trust and the necessary security protocols in place, no UK casino online will survive. Each casino with a UK license protects your private information with 256-SSL encryption keys. They are watertight, and banks across the globe use it.
  • Plenty of Games: British gamblers can pick and choose from more than 3,000 casino games. NetEnt, Microgaming, Play N’ Go, Yggdrasil, and plenty more design the games they play. Whether it is real money slots, table games, progressive jackpot slots, or video poker.

  • Banking: Our top UK online casinos list an array of banking options. They accept e-wallets (Neteller, PayPal, Skrill), Bank Wire, Visa, MasterCard, Checks, Paysafecard, and virtual currencies like Bitcoin. Although Bitcoin is not mainstream yet. UK casinos clear payments within minutes up to 3 business days.


Registration and Bonus

Now that you know more about the most important criteria we use to rate our top UK casinos. In the next section, we look at the deposit or welcome bonus, and why you must accept it. Before you can latch onto your bonus, you must register an account. To best illustrate our point we’ll use Trada Casino as an example. When you click ‘Join’, a short online form pops up. Fill in your name, surname, email address, and some other personal stuff. The registration process won’t take more than 5 minutes of your time.



Once you registered an account. You can browse the various slots for real money and promotional offers in the casino’s lobby. Note, you qualify automatically for a bonus of 100% and 50 Bonus Spins. As well as 10 Welcome spins on the Book of the Dead. Before you can apply for the bonus you must deposit £/$/€20.

Once you made the qualifying deposit for the bonus. The UK online casino credits your account with a bonus of £/$/€20. Instead of playing with £/$/€20, your new improved bankroll is £/$/€40. See the difference? Before you can withdraw your winnings you must clear the wagering requirement of 25x. That’s just the gist of the welcome bonus offer. We suggest you read the terms before you accept it. The bottom line about the bonus is that it gives your bankroll a boost, and it increases your winning chances. Any UK casino’s bonus offers are unique because they have the lowest wagering requirements. Plus, their terms are player-friendly!


UK Online Casino Games

Our trustworthy UK online casinos cover more than 3,000 casino games. It’s a prodigious amount, to say the least, and almost impossible to play all of them. All we can say is gravitas! It’s not only a jumble of games they offer you. Each UK casino online has its own category of games. They divide them into slots, table games, progressive jackpot slots, video poker, Live Casino, Mobile Casino, and specialty games. Just so you know, the majority of the games are slots. The UK Casino further divides the slot games into classics, 3D, video slots, and progressive slots. Before you risk your money there is a free slots version too.



Online slots are the beating heart of any UK online casino. Brits love them because they require no skill and they pay out vast sums of money on a single spin. They also have several layers to them. Slot games offer RTPs in excess of 94% right to 100%. They can be low, medium, or high variance with jackpots of up to 80,000x your stake. And slots vendors pad them out with Free Spins that have majestic multipliers of up to 50x. The multipliers can also combine to give you an even bigger multiplier of up to 60x! The remainder of the in-game bonus rounds is Re-spins, standard wilds, Sticky, Shifting, or Expanding wilds. The last bit is the Pick Me game where you click on special symbols to reveal a cash prize.


Buy Option

Big Time Gaming is the first real money Megaways slots developer to add the Buy Feature to its slot games. The Buy Feature in the Megaways slots copped criticism from the British Gambling Commission. The British Regulator is of the opinion it exploits problem gamblers. As such they asked developers to remove it from their games. The purpose of the Buy Feature is to activate the Free Spins right away but at a cost. The cost ranges from 50x up to a pricey 100x your stake. There are no guarantees that you’ll win back the money from the Free Spins you invested in the Buy Option. Yet, it’s one of the most innovative features to hit the online slots world.
