Choosing an Online Slots Site 2018

Choosing which online slot sites to visit and sign up to can be a daunting task in this day and age. Over 30 new online casinos opened last year that were approved by the UK Gambling Commission. That's one every ten days and this growth of casino sites is set to continue well into 2020. So how do you choose which casino is best suited to you? Reading other players' experiences and reviews is a good place to start.

Many sites will have an average score, but it’s best to read the individual reviews to see what each person’s user experience has been. One player may be more aligned to your needs than another and this can help you identify what software the casino uses, how big the game selection is and how the bonuses work. Online slots casinos regularly add new games and amend their bonus structure, so it’s always best to try a casino first hand rather than solely relying on reviews. Most online casinos offer a demo mode so prospective new members can try before they buy.

Understanding Slot Sites Reviews

Online casino reviews are normally based on a number of different criteria, including user experience, what software runs the site, security and customer support, and, most importantly, bonuses and promotions. There are specific slot sites reviews that will offer more detail about what games are available, on what platforms and how the bonuses are tied specifically to online slots. Some reviews may give a score out of ten, while most offer a summary that highlights the pros and cons of each casino.

Why User Experience is Important

One of the most important aspects of online slot sites is its user experience. This is essentially how easy it is use, with the usability often determined by how simple the site navigation is. Many casinos offer different sections and categories within their slot sites section, so it'a crucial that players are able to move freely between different areas and effortlessly switch from one game to another. In this modern age of mobile devices, user experience and usability can also look at how easy it is to cross from one platform for another, in the hope that this will be a fluid, seamless experience that's the same whether on a computer, tablet or smart phone.

Evaluating Game Selection

Reviews of casino slot sites will often have a large section devoted to the slot game selection of that specific website. They normally follow key guide points that help determine whether a player will choose to visit that casino. Questions asked may include how many games are on offer, what type of games, what game developers are providing them and whether they can be played for free. The number of games on offer at online casinos can vary wildly, from a handful to several hundred.

The number of titles on offer is usually tied to whether that casino has an exclusive deal with one specific software provider, so it only uses their games, or whether it hosts slots from several slot suppliers. There are dozens of iGaming designers and some players may have a favourite one, in which case finding a casino exclusive to that developer might be preferred. Others may wish to sample the best of all designers, so they should find one with an all-encompassing list of providers.

The types of slot games on offer will be broken into several categories, from progressive jackpots and classic fruit slots to the latest 3D video slots, or VR slots using VR headsets to play. Many casinos break these categories down, so players can check how many of each type they offer. The best way to evaluate a game is to try it for free. To check whether a game can be played for free, visit an online casino and click on a game. Most casinos will offer two options, play for money or play for fun. Some online casinos might need you to become a member even if you are just playing for free, while others may not offer this option at all.

The Safety and Security of Slots Websites

Players should feel confident when sending money or personal data to an online casino that this information and data is safe and secure. In order to obtain a UKGC license, online casinos must ensure that their security is above reproach. Casinos are aware that this can be a key factor as to whether someone joins their website and often list the type of encryption technology and software used in its FAQ section under security. Most casinos use a standard Secure Socket Layer (SSL) encryption link between the server and browser, ensuring all transmitted data is protected. These SSL links usually come in 128-bit or 256-bit encryption, and both types are well suited to protect your flow of money and information.

Why Do Most Online Casino Sites Offer so Many Slots?

Variety is the spice of life and most online casino sites offer a vast range of slots to cater to the widest audience possible. Some players may enjoy games based around different themes, or designed by specific software providers, so it's important that online casinos can try and satisfy all of its members. At the same time, online casinos add to its existing catalogue every week to keep the casino updated with fresh new titles so it can entice new players with the most recent releases.

Can You Download Slots Sites?

In this day and age of instant play, where players can seamlessly switch from playing on their desktop browser to a mobile one, many slot sites do not see the need to offer a download of their casino. The browser-based experience means casino members are not restricted to the device that a download would need to be installed on, which was often the case when internet casinos first appeared. However, a small number of casinos still offer apps for both desktop computers and mobile devices like smart phones and tablets, allowing players to play offline.

What Slots Sites Have the Highest Payout Rates?

A return-to-player (RTP) value of a specific game is a payout percentage based on how often a player is likely to win. Higher casino payout rates mean that players are more likely to celebrate winnings from these slots, with the most generous ones offering a rate of 95% or above. The RTP is usually determined both by the software developer of the game, and the casino hosting it. Here is a list of the best UK casinos offering the highest RTP in 2018:

  • Thrills Casino = 98% RTP
  • Mr Green Casino = 97.38% RTP
  • Kaboo Casino = 97.30% RTP
  • 888 Casino = 96.85% RTP
  • Dunder Casino = 96.45% RTP

Gamble Responsibly with Online Slots Sites

At the end of the day, everyone wants to have fun and win some money when playing at online slot sites. However, it is important that players are aware of how to gamble responsibly. Casinos help players regulate their gambling using a number of tools. The first is that all slot sites have betting limits on their games, so each spin has a ceiling on the maximum bet. Online casinos also stipulate maximum deposits, which determines the amount players can pay into their account on any given day. Many slot sites also offer self-regulation, giving players the option to impose lower limits on themselves.
