Best Slot Games

 

Image result for book of dead

The best online slot games can be found on our Top 5 Slot Sites table. All of the casino operators found here have extensive slot game libraries and have been chosen specifically as the best sites to play slots games.

There are thousands of online slots available to play at casinos today and in the future the number will grow considerably. With such a wealth of options to choose from it can be easy to miss out on some top slot games and bonuses.

We try to assess as many slot games as possible when we review a casino site to try and unearth some real slot gems. Invariably we find that nearly every casino site that we encounter we discover an exciting new slot game to play.

We also like to talk about live casino games.  Every true slots lover also loves the thrill of live dealer games!  So expect to find examples of the best online blackjack the net has to offer and the most thrilling live roulette stories you can find!

Every slot fan has a “favourite” game, this could be one of the popular classics such as Starburst, Rainbow Riches or Mega Moolah, or it could be a new slot game developed since 2018 which encompasses all the thrills and spills but with the added visual element of amazing graphics.

With so many online slots to choose from you could easily pick from hundreds to choose the best slots online. Many of the most popular slots games are well-known because they have been used as the focal-point of gambling online for casinos.

For example, many of you will have seen promotions for online casinos such as ‘free spins on Starburst’. This game in particular is hugely popular and it is no coincidence that it was the chosen game for many casino site promotions.

That being said, Starburst is actually one of our all-time favourite slots!.

Slot Sites – Best Online Slots UK

There are many casino sites that allow for UK players but how many of them are actually worth bothering with? Well, we can tell you having tested hundreds of sites that the answer is, not so many.

Image result for ukgc

Firstly, we must do the essential safety checks at a casino site to ensure that it is UKGC licensed and is fully tested by independent software testers such as ecogra. This ensures that any data and transactions are completely secure and that the casino games are fair.

We can then look at the casino sites and what they have to offer in the slots department. Making it onto our Top 5 Slot Sites table is no mean feat, with as many as 80 potential candidates we must do extensive testing on our shortlisted casino sites.

This basically means that we get to play online slot games for hours at a time and review them accordingly – it’s a hard job but someone has to do it!.

Another great place to check out UK slot sites is over at our good friend’s excellent website Zamsino where you’ll find up-to-date reviews, bonuses and guides.

As you can see from our Top 5 Slot Sites table we list the biggest casino bonuses in the UK from the chosen best online slot sites with UKGC licenses.

Best Slot Sites For Winning

There are a couple of good contenders for this in our best slot sites table. It is important to remember though that all games at any reputable online casinos are completely random. This means that any previous wins at an online casino shouldn’t be considered as a “sign” that this online casino gives you the best possible chance of winning at slots. It is only natural that players will flock to an online casino following news of a big win. Each one looking for that next life-changing jackpot-win. A good approach for choosing the best slot sites for winning is to find a top slot site that also has an outstanding welcome bonus for a new player. Also, it is always worth looking at any free spins no deposit promotions to test out a new casino before making any deposits.

Best Slots – RTP (Return to Player)

Slots RTPA big consideration for any slots player looking to try out some new slot games should be the RTP. For those of you that aren’t familiar with the term “RTP” is simply means “return to player”.

This is the average amount set by ecogra (or other software testing company) for winnings. For example, Rainbow Riches has a 97% RTP meaning that for every £100 deposited you would expect to recieve (on average) £97.

Obviously, this is just an average but it is based on thousands and thousands of spins. But there are other games that have similar RTP levels as online slots and can have the same payout potential.

A good example of this would be Monopoly Live which was recently released by Evolution Gaming. It is based on the same concept as the Dreamcatcher wheel but has a Monopoly theme with extra features. We just wanted to give the game a wee mention here since we play it so much!
