Almost all of the best slots sites let you practice using a variety of free games so that you can become accustomed without having to stake anything, while a multitude of enticing bonuses, free spins, as well as a welcome bonus can be the catalyst for new players.

How do we choose the best slot sites?

A lot of thought goes into being able to bring you the top sites to play slots, substantiated by the fact that our experts have decades of experience in the industry as players, particularly the best online slots UK focused. It means that our selection process is considered, with each site meeting a number of important criteria.

By spending a considerable amount of time playing and testing each slot site before we review them means that you can be confident that you are receiving highly knowledgeable and crucially, unbiased information about each one going into intricate detail.

Every top slot site that we offer is constantly monitored on a regular basis and as such we stay up-to-date with all of the changes that are made. Subsequently, we update our reviews as changes occur, even adding new UK slot sites or replacing old ones with new, better ones to meet our player’s high standards.

How to pick the top slot sites

There are a number of factors to take into account when it comes to choosing the best sites. While we understand that not every slot site will appeal to everyone, based on personal taste and interests, there are certainly a few things that you should consider before you commit to registering to one.

Arguably the most important thing to do is to check that each slot site is licensed and the best sites invariably are. Every slot website that we work with is licensed and regulated, which means that adhere to industry legislation and are monitored by the relevant licensing organisation regularly. Meanwhile, security features such as SSL encryption ensure that your data is secure at all times.

By scrutinising each of the best slots sites to make sure that they have an abundance of slots and games from a wide variety of suppliers is also a very good sign that it is reputable. If you are unsure, our reviews go into extensive detail about the games on offer at each of the best slot websites, as well as the numerous suppliers, including NetEnt, Microgaming and Playtech to name a few.

Having an understanding of the RTP (Return To Player) and slot volatility will help to give you a clue about certain variables such as payout frequency on each slot and how big or small payouts are. Slots with a high volatility can incur the most risk, meaning that you may have to wager for a long time, but they have big payouts, while slots with a low volatility mean that they payout little and often. Our reviews go more into detail about RTP and volatility for each slot site that we work with.

For some players, bonuses and promotions are important, because if they are generous, it helps to keep you interested for longer. Our experts provide comprehensive information about these in each review because we appreciate that these form an integral part of the decision-making process when it comes to choosing the best slot sites.

Every slot site that we work with has very convenient and fast withdrawal and deposit systems in place which means that you have funds available instantly when you make a deposit. Ultimately, our reviews provide information about each of the main decision-making variables, so it is definitely reading through each one before you make a commitment.

Payment options at slot sites

Credit/Debit Card

Still a popular choice with players due to the convenience that this method offers. Simply by registering your card details when you sign up to your preferred slot websites, often enables you to then make deposits simply by confirming with your three-digit code (CSV) if you elect for the slot site to remember your card details each time.


A handy e-money transfer payment system, most of the new slot sites now offer this as a payment method. Acting as an online merchant this can transfer funds to and from bank accounts, adding an extra layer of security.


A UK-based e-commerce payment system, similar to Neteller, Skrill focuses on low-cost transfers if you are based internationally. Fundamentally, it uses similar principles to Neteller and most new UK casino sites include this in their payment options.


Arguably the most popular internet payment gateway and used by millions of people worldwide, PayPal is offered as a payment option by virtually every online casino and is considered a very secure method.


One of the most innovative payment systems in recent years, this is a payment system which allows you to deposit via your mobile, by entering your mobile number to confirm each deposit. This can be done in literally a matter of seconds and is one of the most secure methods. Whatever you deposit is then added to your mobile phone bill each month and Boku is one of the main providers of the ‘pay by mobile casino’ method. Because this is such a new and innovative method, not all slot sites will offer this option, though our reviews will give an indication as to which ones do.


This payment option allows you to purchase vouchers to use for your gambling purposes, crediting your betting account with exactly the amount that the voucher was worth. These typically vary in amounts from £10 to £100 in multiples of 10. To confirm each voucher at your slot site of choice, you will be required to enter in a 16 digit code.

It is highly recommended to use a payment method which has low to no fees for making deposits and withdrawals - some online transaction gateways can incur costs, especially for international payments so it is always worth checking if you are not sure. Because our reviews are unbiased and accurate you will find out which slot sites offer payment options which charge transaction fees. Each slot site that we work with also has SSL encryption which means all of your payments remain secure.

It is key that you read and understand the small print attached to any kind of bonus and/or promotion. This usually refers to the terms and conditions that each slot site requires new payers to agree to upon registering and opening accounts, with the prompt often being in the form of a tick box.

As one of the most attractive parts of an online slot site, it is recommended to stay updated with the latest bonuses and promotions, especially the best slots websites no deposit bonus-related, which means you don’t have to part with any cash though are given some funds to play with.

A lot of the best online sites change their bonuses often as a way of enticing and retaining customers while new operators are constantly competing to innovate, some even offering a string of bonuses and generous welcome packages.
