Why Choose a New Slot Site

Many players would prefer an established site that has existed for quite some time. There are reasons for that. These sites have thousands, even hundreds of thousands of players, which is a testament to their reputation.

However, new slot sites often offer better bonus terms and conditions precisely because they know they need to compete with renowned and well-established sites.

And when it comes to other things, a new slot site can still be licenced in the UK, regulated by the UK Gambling Commission, so you will be certain that you’ll be protected.

The welcome bonus is usually the best bonus that new slot sites in the UK offer. If it's a generous and attractive offer, of course, it makes sense to register and claim this bonus.

The next thing you will need to check is the selection of games. It's up to your choice to compare which slot site offers the best games, depending on your preferences and what type of games you’re looking to play.

How We Rate New Slot Sites?

Before you deposit your money and play your favourite online slot games, you first need to find a suitable slot site that will provide you with a fun and, at the same time, secure experience. Nowadays, many new slot sites are being launched on a daily basis, and it can be hard to make the right choice. But don't worry, we've got your back! 

Here at SlotsWise, we don’t just look at the homepage and the site's welcome bonuses. In fact, we thoroughly research and test each slot site individually before we recommend it to our readers. With this in mind, we’ve decided to give you more insight into how we rate the new slot sites and what we take into account before we recommend them on our site. When we discover a new slot site, we immediately look into the 7 most important things that all great sites must have:

  • Bonuses and Promotions
  • Games Catalogue
  • Game Software 
  • Security and Licensing
  • Banking Options
  • Mobile Usability
  • Customer Support 

You will see that we listed Security and Licencing as fourth, but we put great emphasis on this. If you’re a UK player, you can be 100% certain that the UK Gambling Commission licenses all sites that are displayed here.

Whether you're an experienced slots player or just an enthusiast who occasionally follows the latest trends, gaming developers continually announce and release new online slots, aiming to enrich their offer and improve the overall experience. There will be a lot of new slots sites as well. So, above, you will find the best slot sites for this month, and below you can read more on how to choose the right new slot site.

Bonuses and Promotions

Some of the most important features of the new online slot sites are the bonuses and promotions they offer to attract new players and keep the existing ones. Online bonuses are much appreciated by slots fans and can be found in different variations. Bonuses are the enticements that keep players interested. Online slot sites make sure that you'll be welcomed with the latest bonuses that they have to offer when you arrive on their page.

How to Activate a Bonus

To learn how to activate a bonus on a slot site, you have to read the site’s terms and conditions at first. Everything you need to know about the bonus is included in that section. Usually, online casino sites require you to register on the site and deposit a small amount of money to activate the bonus. Some sites don’t require a deposit for activating a bonus. It all depends on the type of bonus and the site’s requirements. Also, there might be a time limit on the bonus, giving you a certain period of time to activate and use it. Once you fulfil everything that the site requires, you’ll be ready to use the selected bonus.

What are Wagering Requirements?

Once you become part of the online gaming world, you’ll notice that the term ‘wagering requirements’ appears on every slot site. That’s why you must know what are wagering requirements and how they work.

Wagering requirements are the requirements that the player has to complete to be able to withdraw their winnings. Slot sites with wagering requirements require players to play with a certain amount of money before they’re able to withdraw any winnings in cash. If the player doesn’t meet the requirements, they won’t be allowed to withdraw the money. So, before you join a slots site, make sure to check the wagering requirements. The most trustworthy slot sites will clearly display this info, and you can find it in the terms and conditions. Luckily, some slot sites allow you to enjoy your bonus without having to meet any wagering requirements.

Bonus Terms and Conditions 

We’ve already mentioned how important it is to read the terms and conditions that come with a particular bonus offer. Before you accept a bonus offer, you must read these requirements. Always look for the most important information about the bonus before claiming it:

  • What's the minimum deposit for the bonus;
  • Does the bonus have wagering requirements;
  • Is there a time restriction on using the bonus;
  • What games are included in the bonus;
  • Is there a promo code to enter

Checking for these things about a bonus offer will help you get the best out of it and take advantage as much as possible. Don't worry, the best slot sites will have all of this information properly written in the Terms and Conditions section.

Welcome Bonus

These days, almost every online slots site offers a welcome bonus, also known as a sign-up bonus or a first deposit bonus. This bonus is a great way to start your gaming journey at a certain site. As the name suggests, the welcome bonus is the bonus that slot sites reward when players register on their platform. It can come in the form of free spins, bonus funds, and more. The welcome bonus is a major advantage of playing online rather than playing in a land-based casino. If you’re interested in playing at a slots site, you should definitely take advantage of it. 

Usually, the site will require you to make a small deposit to be eligible for the welcome bonus. However, there are slot sites that give you the chance to claim a welcome offer without making a deposit. No deposit bonuses are becoming more and more popular in the gambling world. All you need to do to claim a no deposit bonus is register at an online casino that offers this type of bonus. Therefore, don’t forget to read the site’s terms and conditions before claiming the bonus.

Existing Player Promotions

Once you’ve joined a new slot site, you’ll notice that there are plenty of other bonuses and promotions apart from the welcome bonus. Each slots site comes with its own promotions that can run on a daily, weekly or monthly basis. They can include a match deposit bonus, a free spins bonus, happy hours, cashback, bonuses for new games, etc. 

One of the promotions that the best slot sites run and players love the most is the free spins bonus. The free spins are solely credited to online slots, and they usually come on a specific game. Free spins can be a great benefit for every player in this industry. In that way, you’ll be able to try a particular game chosen by the site for free. Who knows, maybe it’ll become your next favourite slot!

Another very popular promotion that the best slot sites run is the match deposit bonus, also known as deposit bonus, matching bonus, and reload bonus. When a slots site offers this type of promotion, they will match the money you deposit in the form of a bonus. There are different matching bonus variations suitable for players that make small, medium and larger deposits. This bonus can be split into three categories: first deposit, compound, and high roller bonuses.

Don’t forget that these promotions might come with wagering requirements, for which we’ll talk below. For that reason, it’s important to take your time and read the site’s terms and conditions before claiming the bonus.

VIP Clubs

The best sites have become at the top in the online gaming world because they care about their players and treat them like royalty. Everyone likes to feel important, and that’s why slot sites run VIP Clubs for the most loyal players. The VIP Clubs are the highest level of the sites’ promotions. Apart from the regular promotions, a VIP Club member can receive many other exclusive promotions such as a special VIP manager, faster customer service, bigger bonuses, VIP-only bingo rooms and promotions, VIP events, higher cashback, and much more.

To join a VIP Club, you have to be invited by the site to meet the qualifying criteria. Also, a VIP manager on the site can contact and invite you to join the club. Plus, the best slot sites allow you to transfer your VIP membership from another site. Once you have joined a VIP club, you may be required to fulfil certain requirements to maintain your VIP status. That’s why it is important to read the site’s terms and conditions and learn everything you need to know about its VIP club. 

Games Catalogue

When you visit a slots site, you’ll notice that the main focus of it will be the slot games. However, most slot sites come with a range of different games for players who like to try something different. Here is the list of games that can be found at the best slots sites.

Slots 

This is perhaps the most popular online casino game in the gambling industry. Because of their popularity, many software developers are working on creating new and innovative slot games. This has resulted in an incredibly diverse section of games that are available at the casino sites.

Playing online slot games is very simple and easy, and you’ll immediately learn how to play them. When identical symbols appear in a certain pattern called a payline, players win a particular amount of money depending on the symbols' number and value according to the paytable. In order for you to spin the reels, you'll have to click the ‘spin’ button. Once you start a round, all you have to do is hope that three or more symbols will land on a payline and start from the leftmost reel.

The traditional games present in slot machines in the land-based casinos featured three reels and symbols like fruits and lucky 7s. Nowadays, most of them will feature five reels and a wide range of themes such as fantasy, fairytale, sports, TV, adventure, gold, mystery, and more. However, the classic three-reel format is still popular today, so there are new three-reel slots released as well. Even without considering the number of reels, themes, symbols, there are literally thousands of online slot sites available. There are certain special symbols featured in almost all slots, no matter the type. They are wild symbols, scatter symbols, and multipliers. These symbols can give you different rewards, such as free spins and multiplied winnings.

Live Casino Games

If you want to play casino games online but want to feel like you’re in an actual casino, you can try playing live casino games at some of the best slot sites. Live casino games are table games that include live dealers. The casino environment is set up in a studio and broadcast to players in real-time over the Internet. Live dealers give players the ultimate casino experience from the comfort of their homes. You can also check out some of the best live online casinos!

Table Games

When you think of a casino, table games will immediately come to your mind. Table games are popular games that can be found in casinos and now in online casinos. In fact, you can enjoy a variety of table games at the most popular online slot sites. Online table games allow you to spin the roulette wheel or take on a blackjack dealer without having to go to a land-based casino. The most popular table games are:

  • Roulette - It’s one of the most exciting casino games that became popular immediately after its invention. Roulette is a game of chance, which means that winning at roulette comes down to luck. This game involves spinning a wheel and a ball. You wager on which pocket or section of the wheel you think the ball will land.
  • Blackjack - In contrast to some other casino games, blackjack has a skill element that can get you some excellent winnings. Blackjack aims to beat the dealer and get your hand as close to 21 as possible. If you go above 21, then you ‘bust’ and lose the round.
  • Baccarat - This online table game is played between the player and a dealer. Each round of play has three possible outcomes - player, dealer, and tie. Players have to place bets on the outcomes before the hands are dealt. The hand that deals closest to nine will win. If two hands draw the same value, the round ends in a tie. 
  • Sic Bo - Based on Chinese dominoes, Sic Bo is all about the three dice. The idea of Sic Bo is simple - place bets on the outcome of the three dice. The dealer puts three dice in a cage and shakes them to reveal the winning combination.
  • Craps - Similar to Sic Bo, this table game is an exciting game where you have to place bets on two dice. The dealer shakes two dice and reveals the winning outcome. There are dozens of possible wagers to make.
  • Texas Hold’em Poker - It’s one of the most popular variants of poker. Each player receives two cards, and then five cards are dealt in three stages. Players have betting options to check, call, raise, or fold. Each player seeks the best five-card poker hand from any combination of the seven cards in total.

Return to Player (RTP) and Variance

If you want to assess how profitable the game is, you can check its Return To Player (RTP) percentage before you play it. RTP expresses the amount of all wagers placed on a game that is returned to players when they win. For example, if a game has 96% RTP, it will theoretically pay out £96 for every £100 wage. The RTP is calculated over thousands of spins and is a great indication of how the slot pays out. The best slot sites will always list the games' RTP, so you can easily check it before playing.

Another important factor that tells you how often you’re likely to form winning combinations is the variance. Variance tells you what will be the size of your winnings and how often the winnings occur. If you play a slot game that doesn’t land wins too often but has potential for large prizes, you’re playing a high variance game. If the slot game you play offers smaller wins, but you and landing them more often, then you’re playing a low variance game.

If you want to know more about RTP and variance, read our guide on it.

Game Software

The new slot sites wouldn’t be so popular if it weren’t for the games’ software developers. Technology has increasingly evolved, which has led to improvements in the games' visuals and audio, plus there have been a lot of innovations in the games as well. In online casino games, gameplay and the whole gaming experience is way better, thanks to the software developers. There are plenty of software providers that specialise in developing high-quality and innovative casino games. Software providers create their own niche and include small consistencies between their games.

Some of the major software developers include NetEnt, Microgaming, Playtech, Real Time Gaming, IGT, Amaya, Betsoft, Evolution Gaming, Barcrest, NextGen, Cryptologic, Pragmatic Play, Quickspin, Gamesys, Play N Go, Big Time Gaming, ELK, Gamevy, iSoftBet, Iron Dog, Nektan, Scientific Games, Realistic Games, Thunderkick, and more. You can find the full list of the most popular and secure software providers in the online gaming industry.

Security and Licensing

For the new slot sites to work securely, they need to be licenced and regulated by the proper authorities. Being a safe and secure site is the most important feature of both the popular and the new slot sites, and you should always pick a properly licenced site. Gaming regulators ensure that the sites provide a secure gaming environment and that players always deposit and withdraw funds safely. Some of the most respected authorities include the UK Gambling Commission, Malta Gaming Authority, Gibraltar Regulatory Authority, and more.

Furthermore, we always check if the sites that we recommend use a Random Number Generator (RNG). RNG is a software that ensures fair and transparent gaming, with equal chances of winning to all players. Also, the best slot sites are supporters of responsible gaming and have agreements with major responsible gaming platforms such as GAMSTOP and GamCare.

Banking Options

Playing casino games online means that you’ll have to deposit funds at some point, so slot sites must provide a safe and secure gaming environment. That’s why these sites provide funds protection and a variety of secure payment methods. These payment methods can include debit cards, PayPal, Paysafecard, Apple Pay, Neteller, Skrill, Entropay, wire transfers, Pay by Mobile, and more. The best slot sites have a quick and transparent withdrawal processing time that allows you to withdraw your winnings safely and securely.

Mobile Usability

We live in a time where people use mobile devices more than desktop devices. Therefore, all popular and new slot sites must be mobile optimised so that players can access the games directly from their mobile. All of the sites we recommend here at SlotsWise are fully mobile-optimised and developed with HTML5 technology, allowing fast and smooth mobile gameplay. Moreover, some of the sites have their own mobile apps available in the stores, so you can download them and access your favourite games.

Customer Support

There comes a time when players need some help or assistance when playing at a slots site. For that reason, the sites need to have responsive customer service that will put the players' needs in the first place. This makes the site even better and attracts more players. Customer service can be in the form of a live chat or a customer support system that is always ready to help the players. In addition, the best slot sites have provided an email address and phone number where players can reach them. They have a 24/7 support system and answer the players’ questions quickly.

Are these slots sites allowed to operate in the UK?

One essential thing is the legal aspect of online gaming. All casinos that are displayed on this page have a licence issued by the UK Gambling Commission. This means that whenever a player registers with this casino, they will be protected by the UKGC. The Commission issues the licenses, but it also oversees whether casinos operate by the law. Online gambling in the UK was legalised by the 2005 Gambling Act, and later amends were introduced with the Gambling (Licensing and Advertising) Act 2014.

When you sign up and play at a licensed casino, you can be certain that they operate according to the law and that your funds and your personal information are safe. The UKGC is the strongest safeguard for UK slot fans. If any issue arises, you can contact the UKGC, and they will assist you with the issue and take measures if necessary.
