Guide to Online Slots UK

You place your bets, spin the reels... sometimes you win, sometimes you lose. That’s online slots in a nutshell, isn’t it?

Not anymore, with new bonus features, side rounds and enhanced gameplay all taking the genre in innovative and exciting directions. Here we look at how to find the very best slot games online and how your choice of online slot sites will go a long way to determining your enjoyment of the games on offer.

What’s Offered at Online Slot Sites?

  • Slot Variety: The best online slots sites will offer an extensive collection of games of differing type, from standard and progressive jackpot slots to 3D and video-based titles.
  • Casino Games: It’s always nice to have a change of scene once in a while, so slots sites that also have a casino section, stacked with games like blackjack, roulette and baccarat, are also welcome.
  • Welcome/Ongoing Bonuses: We all love a good bonus and any online slot site worth its salt should offer a welcome package to new players. But just as important are the promos that keep players coming back for more time after time; these really can make a difference to your bankroll.
  • Loyalty Programmes: Linked to the above, loyalty programmes offer players ‘replay value’ because they reward you for playing your favourite games. Loyalty points are gained and can be redeemed on free spins, reload bonuses and more.
  • Free Play Mode: It is well worth trying out a number of slot games before deciding which you want to wager real money on. And that’s why free play mode is so important; you can ‘try before you buy’!

What Makes the Best Online Casino Slot Sites?

You may want to play the very best online casino slots, but the games are only part of the equation. Consider your user experience: if the site takes an eternity to load, or is a nightmare to navigate, then your enjoyment is going to diminish exponentially.

Also, be sure to ponder whether this is a trusted site or not. Make sure it has security provisions in place to protect your personal data and read impartial reviews about the site before making a deposit.

The best online slots UK platforms will hand out handsome bonuses to new and existing players, but a word of caution: all that glitters isn’t always gold. Think about the wagering requirements attached to any offer and how realistic they are to ‘play through’.

And once you have used that welcome bonus, what else does the slot site offer? Are there ongoing promotions that tickle your fancy? Some sites use welcome bonuses to hook new players, but then offer very little from that point on.

Finding the Best Online Slots

Here's what you should factor in when drawing up a checklist that identifies the best UK online slots.

We’ve mentioned bonuses and promotions already, and while it is tempting to focus on the ‘free stuff’ there are plenty of other items for consideration. Think about payout percentages. These Return to Player (RTP) rates determine how often you can expect to win when playing a particular slot. It’s not a perfect science, but the percentage outlines your win ratio if playing an infinite number of times. Some slots are slow and steady earners, while others offer high variance where wins come rarely but at a higher rate of return.

There are some names in slot game production that are almost a guarantee of quality. Software developers such as NetEnt, Microgaming and Playtech continue to produce the most playable and innovative games around. If a slot site carries an extensive collection of their releases then you won’t go far wrong.

Another thing to think about when considering the best of online slots is how the game(s) look on your preferred device. For instance, some older sites haven’t really been designed to be compatible with newer smartphones and tablets, whereas others have mobile playability in mind. If you plan on playing slots on your phone, make sure the site has been built to make the most of the technology.
