Best Online Casinos UK
Gamblers worldwide should envy UK players because they have one of the most organized online gaming markets. That means there is a huge range of licensed and reputable online casinos.
However, not all UK casinos are truly good. The online casino industry is no different from any other. Think how you can find great restaurants with delicious food at reasonable prices, but there are also restaurants you wish you never entered. It is similar with online casinos. 10% are great, 70% are mediocre and 20% should be avoided.

Each site is fair, safe and pays winnings smoothly and quickly. There are a wide range of casino games and promotions here for you to enjoy.

Popular UK Online Slots
There are dozens of online slots providers available in the UK market. Just to name a few, there is Microgaming, Playtech, NetEnt, Bally, IGT, Aristocrat and Play’n’Go. Here we will go over the main ones and name the most popular slot machines of each developer.
Microgaming Slots: Together with Playtech, Microgaming is a long time leader in the online gambling world. They offer an enormous variety of over 500 slots and over 600 casino games. Some of their most popular and known slots are Thunderstruck, Immortal Romance, Break da Bank Again, Dark Knight Rises, Jurassic Park and the multi-million pound Mega Moolah.
Playtech: Another monster company with an endless number of slots. You can find Playtech slots in many UK gambling powerhouses such as William Hill and Ladbrokes. Playtech’s popular slots include Great Blue, Gladiator, Captains Treasure, Rome & Glory and the famous Marvel Slots series: X-Men, Elektra, Blade, Fantastic Four, Captain America and more.
Net Entertainment: NetEnt is the most successful slots provider of the last decade. It started as a small developing company and turned into a giant corporation. Similar to the previous two, NetEnt is a publicly traded company. If you were lucky enough to have invested 4 years ago, you would have already earned 500%. It’s hard to say which NetEnt slots are the most popular, but we will mention Dead or Alive, Jack and the Beanstalk, Starburst, Gonzo’s Quest and South Park slots.
Bally Technologies: Bally is one of the biggest land slots providers. It’s hard to find a brick and mortar casino that doesn’t have Bally slots. Some of the popular names are Cash Spin, Hot Shot, Money Wheel and Quick Hit Platinum.
IGT: Another company that made its way from offline to online casinos. Popular names include Texas Tea, Cats, Monopoly and the eternal Cleopatra slot.
