Best Slot Sites

It’s no surprise that bingo players also love to play slots, and on this page, we list the best slot sites to play all your favourite slot games. Choose from slot deposit bonuses and free spins with the leading slot sites.

Top Slot Offers

These are just some of the best slot sites we’ve reviewed recently and there are 100s more to choose from. Most slots and casinos site will have different new player offers including deposit bonuses, free spins and sometimes cashback offers.

Always check the individual site’s terms and conditions before you sign up.

Is there a formula to choosing the best online slots sites?

There isn’t a scientific formula for a brand to be considered one of the best slot sites by us. What we do have though is a template of what we look for to ensure that when we give online casinos or slot sites a place on this page, they have met a certain number of the criteria that we have.

It would be easy for us to promote unknown brands and simply tag them as the best, but we’re about ensuring our reviews and suggestions have a genuine thumbs up from people with a wide and varied experience in the online gambling industry.

Welcome package and ongoing promotions

One of the first things we look at for an online slot or casino brand is what sort bonuses are available for their new customers. We expect some sort of deposit bonus; your first deposit should attract a match bonus or free spins.

However, you can only be a new customer once at any given site so we also take into consideration ongoing promotions for players. Do they offer bonuses by email? Are there slot tournaments on a regular basis? These are all things that we consider should be part of a site because it’s not just about attracting your attention in the first instance but also maintaining your interest after the welcome bonus has been long spent.

Other types of bonuses to look out for might be extra spins or bonus spins as part of any casino bonus sign up offer. 

Wagering requirements

As part of the welcome package and ongoing promotions, we also scrutinise the wagering requirements and/or playthrough required on any bonus or free spins awarded. We like to see players given the choice to opt-out of bonuses too so that wagering requirements don’t hinder your chances to withdraw any winnings you may accumulate.

It’s also worth noting that any unused bonus will not be eligible for withdrawal until you have met the requirements for wagering the total bonus.

Wagering requirements are standard in the world of online gambling, more so for slots online than bingo, but they have to be within an industry standard for a site to even get a look at finding themselves on this page.

Some sites will offer no wagering requirement to entice customers to sign up to the site.

Customer service

With the greatest will in the world, and no matter how hard the online casinos and slots sites work to have a comprehensive FAQ section, there is likely to be a time when you need to contact customer service with a query. What we look for is a brand that is responsive in its customer service provision. If Live Chat is available and manned for core hours, this is a definite plus point.

When it comes to other forms of communication with the operator, we prefer to see a short turnaround on email responses and it is preferable if they also offer a telephone option for customers.

Slots portfolio and games selection

We love a slot site with an impressive array of games to choose from but their portfolio does need to have a selection of titles from a variety of different providers/developers. We look for the big names like Microgaming and NetEnt as well as some games from the smaller, upcoming creators too.

We also love to see a smorgasbord of progressive jackpot slots too with a side-serving of live casino and table games from an online casino. The latter two we don’t expect to see from a slots site though. See our Ultimate Slots Guide for Beginners here.

Payment choices

In April 2020, credit cards were removed from the payment options available for use at online gambling sites so when it comes to funding a spin of the reels, we expect to see more than just debit cards on the list.

PayPal is one of the alternative ways to deposit funds at a slot site and we expect other eWallet funding methods to be available too.

It’s worth noting that some eWallet options for depositing do have limitations on the bonuses that are advertised. For example, Paysafecard is often excluded from the welcome bonus and first deposit deals. Other options for e-wallets include Skrill or Neteller which some people prefer and find easier to use when playing online slots. 

A pay by phone option is also worth considering if you want to manage your depositing and banking in one place. Boku is a payment solution that many choose because each transaction is charged to your mobile phone bill.

Ease of use and navigation

There’s nothing worse than not being able to find what you are looking for! Visit any slots sites and it should be easy to locate the game that you are looking for. We’re especially keen on the brands that offer you the functionality to find a title by the developer.

Others may drill a bit deeper and give you the option to search on specific features of a slot like the number of paylines, whether they have a free spins bonus or bonus feature and if they offer a progressive jackpot.

It’s also important to be able to access the responsible gambling pages easily and the account section for deposits and withdrawals.

Withdrawal times

We all play to win so when we do, we want to be able to have our winnings back in our bank accounts or depositing method as soon as possible. On the banking pages of the online slots page that you have chosen to visit, there should be information pertaining to the processing and withdrawal times.

Before being able to withdraw winnings you will have had to supply forms of ID to verify yourself. This process should not take more than 72 hours and you should be clearly signposted to the time scales for this process too.

What are slot sites?

Slot sites are online gambling brands that offer just what the name suggests, a whole variety of different slot games. Some might refer to them as online casinos but actually, there is a slight difference between the two which we explore in more detail in the question below.

You could call any brand that offers instant win games a slot site, and the term does encompass online casinos and bingo sites because both offer a selection of slots to play. It’s just terminology at the end of the day!

Is there a difference between an online casino and a slot site?

This is a bit of a moot point because the only real difference between slot sites and an online casino is the variety of games. Both offer a variety of the best online slots but online casinos also have table games and in some cases, live casino games too. It could also be argued that a site qualifies as a slots casino without any additional table games.

Reasons for playing slots online

Slots can be played both online and at a land-based casino or bingo hall, or even in your local betting shop but there are some advantages to opting to playing online slots.

There are also many bingo sites that offer slots to play too, which comes as no surprise. In fact, we don’t know of any bingo sites that don’t offer slot games!

The most obvious advantage is that you can play online from the comfort of your own home. If you’re not feeling like donning your best bib and tucker for a night at the casino, you can just visit one of the sites listed on this page and still be in your pjs!

Although not quite as available as they once were, you can also play slots online for free. Many slot slots or casinos online offer you the opportunity to spin the reels in demo mode. However, it is worth noting that you may need to register for an account in order to access the demo play. This is because of gambling regulations that require the sites to verify that you meet the 18+ age required to play slots.

Some would say that online casinos offer better odds on their games because they do not have the overheads to meet of a land based casino. As we aren’t privy to the bottom line of a land based and online casino, we can’t substantiate that as a reason.

The choice when playing online is generally greater and the reason is simple; a retail casino only has a limited amount of space for the actual slot machines were as online, the only restriction is the server space available to the operator!

Are there different choices of online slots to play?

There are also new features being created by the slot game developers that all enhance the gaming experience offered when spinning the slot reels.

An example of this is the Avalanche feature introduced by NetEnt. It was first seen in 2010 on their title Gonzo’s Quest. Rather than spinning reels, the symbols on this game fall into place and if a winning combination is created, the symbols are removed and others fall into their place. This creates more winning potential and on this particular game, the chance to increase the payout multiplier with each additional winning combination.

Classic Slots

These are based on the old school slot machines found originally in Las Vegas and feature 3 reels and 1 payline. You can still find classic slots that keep the traditional gameplay from software developers like Microgaming and NetEnt.

Some of the classic slots we like include Double Diamond, Scorching Sevens and Lucky Diamonds.

Video slots

This is a very wide-ranging category for slot games and covers nearly all games you’ll find on slot sites around the world. In essence, a video slot game will feature 5-reels with animations and videos, and all software developers will feature them including Red Tiger Games.

One of our favourite video slots of all time is Starburst which is developed by NetEnt and was launched in 2012.

Progressive jackpot slots

If you’re looking to win big, and sometimes really big, progressive jackpot slots are worth looking at. Progressive jackpot slots are games that are connected or networked together to give a much bigger jackpot prize. Every time a player spins the reels on a game, a small percentage of the losing bet is added to the jackpot prize.

Some of the biggest jackpots can grow very quickly into the millions of Pounds or Euros, and the biggest jackpots can be found on the Mega Moolah slot game by Microgaming.

3D slots

You don’t need 3D glasses to appreciate these types of slots, but the design and gameplay rival some of the best video games available. 3D slot game development can run into very big budgets and the themes created are truly epic design and scale.

Some of the better known 3D slot games popular with slot players include Gonzo’s Quest by NetEnt and Jurassic Park from Microgaming.

Multiline slots

Nearly all slot games can be classed as multi-line slots where there is more than just one playline available to win. Some games feature up to 100 paylines with variations like win-both-ways and ways-to-win which means the payout occurs with three or more symbols from left to right, or any combination.

Immortal Romance is one of the best-known ways-to-win slot game.

Megaways is another variation on multi line slots where the number of rows and reels changes with every spin, with up to 117,649 ways-to-win. One of the best-know games to feature Megaways in Raging Rhino from software developer WMS. The RTP on this game is 96.18% making it a favourite slot machine amongst players.

Pub slots

These slot games are similar to classic slots and usually combine features like ‘nudge’ and ‘hold’ which you would find on a traditional slot machine in a pub or club.

Games like Davinci Diamonds and Couch Potato from Microgaming and popular slot games are categorised as pub slots.

What is RTP?

RTP is an acronym and is means Return To Player. It is a percentage that you can expect to have won back whilst playing the game in question over a period of time. For example, if you choose a slot to play and you have wagered (not deposited) £500 on a game that has an RTP of 96.4%, then your balance should be £482. Some refer to the RTP as the house edge.

When reading this, that might sound like it really isn’t worth your while playing because the calculation used as an example would suggest that you are just going to lose money. What has to be considered is that all forms of gambling are a game of chance and operated using a Random Number Generator (RNG). This means that the result of any spin is random and cannot be dictated or guessed in any way. Therefore, it could be that the RTP on your spins could be either higher or lower than the amount shown.

Below are some examples of RTP on some of our own personal favourites:
