Finding the best site to play your favourite slot games can be a bit difficult. There are more and more new slot sites being launched on a regular basis, so players may find it hard to choose the best option. If you are one of those players, don't worry - you are in the right place. We are here to help you out in your quest for some amazing online fun. 

That’s why we’ve created this guide - to help you find the best new online slot sites where you can play hundreds of slot and casino games.

How We Rate the New Slot Sites

Everywhere you look, both popular and new slot sites offer a variety of bonuses and promotions on all kinds of different slot games. Yes, there are hundreds of slot sites that aim to provide the best gaming experience for their players. However, not all of them will suit your needs. With this in mind, we’ve decided to provide you with more insight on how we rate the new slot sites and what we take into account before we recommend them on our site.

Here at SlotsWise, we don’t just look at the homepage and the welcome bonuses offered by each site. In fact, we make detailed research and test each slot site individually, before we recommend it to our players. Here are the main features we look for when reviewing all new slot sites.

Bonuses and Promotions

Some of the most important features of the new online slot sites are the bonuses and promotions that they offer in order to attract new players and to 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 when you arrive on their page, you'll be welcomed with the latest bonuses that they have to offer.

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 in order to activate the bonus. There are some sites that don’t require a deposit for activating a bonus. It all depends on the type of bonus and the site’s requirements. In addition, 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 in order to be able to withdraw their winnings. Slot sites that have wagering requirements require players to complete a number of playing the bonus 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, there are some slot sites that 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 the minimum deposit for the bonus is;
  • 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, which is 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 a player registers 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 in order to be eligible for the welcome bonus. However, there are slot sites that give you the chance to claim a welcome offer without having to make 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 to 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, it means that they will match the money that you deposit in the form of a bonus. There are different variations of the matching bonus, suitable for players that make small, medium and larger deposits. This bonus can be split into three different categories: first deposit bonus, compound bonuses and high roller bonus.

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 member of a VIP Club can receive a lot of 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 when you meet the qualifying criteria. In addition, 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 in order 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 of the slot sites come with a range of different games, for players that are bored with playing only slots. 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, a lot of 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 number and value of the symbols 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 that were 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 to this day, so there are new three-reel slots released as well. Even without considering the number of reels, themes, symbols, there are literally thousands of games available at the online slot sites. 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.

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. The aim of blackjack is 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 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.

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 visuals and audio of the games, 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. Here you can find the full list of the most popular and secure software providers in the online gaming industry.

Security and Licensing

In order 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 site that is properly licenced. 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 piece of software that ensures fair and transparent gaming, with equal chances of winning to all players. In addition, 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. In addition, the best slot sites have a quick and transparent withdrawal processing time which allows you to withdraw your winnings in a safe and secure way.

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 that we recommend here at SlotsWise are fully mobile-optimised and developed with HTML5 technology which allows fast and smooth mobile gameplay. Moreover, some of the sites have their own mobile apps that are available on 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, it’s important for the sites to have a responsive customer service that will put the needs of the players 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.

Return To Player (RTP)

If you want to assess how profitable the game is, before you play it, you can check its Return To Player (RTP) percentage. RTP expresses the amount of all wagers placed on a game which are returned to players when they win. For example, if a game has 96% RTP, it means that it will theoretically pay out £96 for every £100 wagered. 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 RTP of the games, so you can easily check it before playing.

Variance

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.
