Online Slots UK

  • According to the United Kingdom Gambling Commission (UKGC), there are 181,309 gambling machines in the UK1
  • Online Casino games in the UK account for 37.3% of the total gambling market share
  • On this article, you find a list of all the most popular online Slots in the UK

There are so many Slot games you can play online in 2019, that finding the best ones is not an easy task.

Some games come with stunning graphics and animations but kill all the fun with ridiculously low Return to Player rates (RTPs).

Others give you higher chances to win something but look like they just came out from a shop in Camden Market:

They look weary, tired, and expensive.

To help you find all the best online Slots available in the UK, I compiled a list of the very best games you can play in 2019.

All the Slots on this page are available at online Casinos approved and licensed by the United Kingdom Gambling Commission (UKGC), so you can play being safe in the knowledge that everything is legal and as regulated as it should be.

The article opens with a full list of the best online Slots followed by the description of each and every game.

All Slots are available for free and for real money play. It's up to you to decide if you want to play the demo version with free (virtual) money or jump on the real thing right away.

Either way, you'll be asked to register to play. The registration is 100% free (choose your nick, enter your email, and go) and it guarantees you a welcome bonus, should you decide to try the real money play.

Do keep in mind that t&cs apply on every bonus you unlock and activate. From the free spins you get on signup to the match bonus you receive as you download a Casino app, you’ll have some wagering requirements or some other conditions that apply to your winnings.
