Types Of Casinos Slots: What You Need To Know

Further Information

We can say that there are three main categories of slot machines. These are:

  • Classic slots: These are also known as “fruit machines” or “penny slots” too. They have fewer paylines and symbols, i.e. 5 symbols and 3 lines. Usually, they do not have special symbols or bonus rounds. They are very easy to play and their payout frequency is more than satisfying.
  • Video slots: The majority of the best new online slots UK fall into this category. These are “advanced” games with more symbols and paylines, i.e. 12 symbols and 20 lines. They have better visuals and contain special symbols & bonus rounds too.
  • Jackpot slots: These can be classic or video slots, but in any case, they have a jackpot payout – a grand prize big enough to make you a rich person. And if the jackpot is progressive (which means it keeps increasing with every game played, until someone wins), you can really win millions, literally.

  • credit card list
  • Credit Cards

    VISA or MasterCard– your choice. UK slot casinos support both of them.

What Is RNG And Why Do Slots Sites Use It?

RNG is short for “random number generator”. Simply put, it randomizes the results of a spin and makes it impossible to guess them. Let’s say you are playing Immortal Romance slot machine. Each symbol in this game has a numerical counterpart, i.e. “1476” means the wild symbol. When you click the “spin” button, the RNG software generates a random number. And if this number is 1476, for example, you see the wild symbol on the screen. This is a very simplified explanation but you get the idea: Nobody can guess the result of the RNG software, so nobody can guess which symbols will be displayed on the screen. The software guarantees the fairness of slot games and that’s why all of the best new UK online slots use it.

FAQ About Best Online Slots UK

Sure. Nowadays all UK slots casinos are based on HTML5, which means all of their games and services can run on any browser (desktop or mobile) without installing anything.
As explained above, the RNG software is what makes them fair. You can always check for a fairness certification from a third party too, such as eCOGRA.
Yes. Real money gameplay is not mandatory: You can try all the slot games for free and switch to real money gameplay anytime you want.
There is no real limit – the current world record is 18.9 million Euro. Any player can win more than this, it depends on how lucky you are.
