With the many different variations, you may be struggling for where to start. If this is the case, allow us to help. In this guide, we’re going to discuss the different variations of online slots, how you can get started, the benefits of playing online slots, best providers, how we rate different platforms, and a whole lot more. Let’s jump into it!

Benefits of Playing Online Slots

Before anything else, why should you even consider online slots? Whether you have experience with online casinos or not, here are some of the benefits of choosing online slots.

Perfect for All Budgets

Firstly, some games are reserved for serious players and some are available for people of all budgets…online slots fall into the second category. It doesn’t matter whether you’re a high roller or a beginner wanting to spend pennies, you’ll find a game for you in this area. As well as the penny slots, most casinos will also have high-roller progressive jackpots where there’s a chance to win six figures. If you don’t want to spend any money, you could even try the free demo games.

Easy

Of all the online casino games, slots are perhaps the easiest to pick up and play. The games are straightforward, there’s little fuss, and you don’t even need to worry about strategies and having skill. Ultimately, the game is all about hitting the spin button and crossing your fingers.

Exciting

Just because slots are simple, this doesn’t make them any less exciting. Depending on the game you choose, there are all sorts of enjoyable themes, bonuses, and animations to enjoy in this niche. Remember, most online casinos have hundreds of slots to choose from, so you’re likely to find a handful you enjoy.

Great RTP

With an online casino, every game has a return to player (RTP) percentage. Generally speaking, the RTP percentage for online slots is much stronger than physical slot machines. Therefore, your money goes further online and you have more opportunities to win money.

Lots of Variations

As we’ve just mentioned, you will find slots of all shapes and sizes. With lots of different themes and animations, some revolve around animals, some around sports, and some around the different nations of the world. Thanks to the many high-quality developers, new games are added constantly.

Mobile Friendly

As more casino players use their mobile devices to play online, developers and casinos have accommodated this trend with more mobile-friendly games. No matter where you are – whether in the dentist waiting room, on the train to work, or on the sofa – you have access to great slot games on your mobile device. These days, most casinos have a positive mobile experience.

Fun

Types of Online Slots

When choosing between slots, it’s easier to break the market down into different sections. For example, the different types of slots include:

Jackpot Slots

As the name suggests, these are the games with the big money. In the past, plenty of people all over the world have won life-changing amounts. While standard jackpot games allow players to win a set amount and then reinstate this amount after, progressive jackpots accumulate over time. When somebody wins, it resets back to the starting point.

One benefit of jackpot slots is that they’re normally hosted by the developer rather than the casino. This means that, when the jackpot builds, it does so over several casinos. With more players accessing the game, the jackpot grows quickly (and to large amounts!). Examples include:

  • Major Millions
  • Arabian Nights
  • Mega Moolah

Classic Slots

Next, these are perhaps the most basic of slot games. With everything stripped back, there are fewer pay lines and fewer winning combinations. Often, this is the best place for beginners to start because they don’t have all the bells and whistles seen with more extravagant productions.

Despite the simplicity of classic slots, we should note that many have the highest RTP of all slot games. For example, popular classic games include:

  • Break Da Bank
  • Double Whammy
  • Super Nudge 6000

Branded Slots

With branded slots, you have games that are linked to a video game, TV show, movie, sports team, or another type of brand. More often than not, developers have the support of the brand and this means that more effort (and resources!) goes into making these games. If you want a great experience, there’s no better place than with a branded slot. With players associating the slot game with the brand, the latter can’t afford to produce a poor game. Examples include:

  • The Simpsons
  • Jumanji
  • The Dark Knight

Video Slots

Essentially, video slots are classic slots that have been spruced up with modern technology. Features include slot bonus rounds, pay lines, side games, mini-games, and awesome graphics. Keeping it interesting for developers and players alike, RTP percentages change from one game to the next. Games you’ll find in this niche include:

  • Dead or Alive
  • Gonzo’s Quest
  • Starburst

In this section of online slots, you might even find 3D slots which are where video slots have been taken up yet another notch in terms of graphics.

Biggest Online Slot Providers

When you move between different online casinos, you will see some popular names coming up time and time again. Over the years, a few brands have been able to secure a solid footing in the market. Now, it’s hard to imagine a market without the following:

Playtech

If you like Superman, Matrix, or even American Dad, Playtech is home to some of the most exciting branded slots. Away from brands, they also developed Age of the Gods and many other fun games.

Microgaming

Based in the Isle of Man, Microgaming is often considered one of the best online casino developers alongside Net Entertainment. You’ve probably played a Microgaming online slot since they produced Mega Moolah, Mermaids Millions, and Game of Thrones.

 NetEnt

This time, we’re heading to Sweden and another with a fantastic reputation. They developed Mega Fortune, Starburst, and Gonzo’s Quest…need we say more?

IGT

Short for International Game Technology, this brand is present across a multitude of countries and continues to develop hits such as Pharaoh’s Fortune and Family Guy. In case you need to question IGT’s prowess, they have offices in London, Rhode Island, Las Vegas, and Rome.

Play’n GO

Lastly, we have another developer from Sweden and one responsible for Book of Dead, Troll Hunters 2, and Mystery Joker. Every year, Play’n GO seem to develop plenty of exciting new names.

Getting Started with Online Slots

How do you bet on online slots? Allow us to explain.

Step 1 – Pay Attention to Paytable

After choosing a game, pay attention to the payable because this will display possible winnings for any given bet. Furthermore, it should explain the minimum and maximum amount you can wager on the game. Depending on the game, the display of potential payouts may change from a ratio to a multiplier to a percentage. From here, you’ll also see additional features of the game.

Step 2 – Choose a Stake

Hopefully, you have chosen a game that allows you to choose a stake that matches your budget. For example, those who only want to bet pennies don’t need to play the high roller games. On the other hand, high rollers don’t want to be limited by what they can stake. For many games, they actually use ‘coins’ for stakes and coins have a real currency value. Make sure you understand the value of coins before making a mistake.

Step 3 – Select Pay Lines

Normally, we recommend playing the games with several pay lines because it can boost the chance of winning. Of course, the stake increases as you bet on more pay lines. Although it can be easy to get carried away, spend a few spins just getting used to the game and betting across several pay lines.

Step 4 – Hit the Magic Button

When you’re ready, and you’ve set the stake, the only thing left to do is hit the spin button. How will you know if you’ve won? Well, in our experience, everything will start flashing and you’ll get a message pop up. If the sound is turned up, you might even get fanfare music to celebrate the win. When playing with real money, you should see winnings enter your casino account immediately.

How We Judge Online Slots and Casinos

On this page, you will see our recommendations for those who want to play online slots. But how do we choose which services to recommend and which ones to avoid? Well, we have a fantastic team and test each platform. This is always the first step, and it allows us to play different online slots across various websites. Just because a slot game is available on five different platforms, this doesn’t mean the experience will be equal for them all.

Using our experience, we pay attention to the graphics, depositing/withdrawal methods, speed, fairness, usability, and other features. It’s all well and good winning money on slots, but this joy quickly turns into frustration if the withdrawal stage takes two weeks.

With this in mind, we also consider user experience, mobile experience, bonuses, welcome offers, game choice, customer support, and a number of other topics. Since we test each platform, we make a note of the registration and depositing process. We look at the security of a betting website and how the VIP programs work. We consider bonuses not just for new customers but for existing customers too.

For us, the very best online casinos have a few important qualities. The best services:

  • Work across multiple devices
  • Have a good choice of games
  • Offer plenty of banking methods
  • Have a strong customer support
  • Pay customers on time
  • Treat all customers with respect (bonuses for existing customers is a part of this)
  • Keep all financial details secure
  • Offer fun and rewarding experiences

FAQs

To finish, let’s answer some of the most common questions regarding online slots.

Are online slots and casinos safe to play?

Absolutely, as long as you’re cautious and only use a regulated and trusted website. If you have no experience with online slots, it’s natural to be nervous and want to play safely. Remember, all platforms recommended on our website are regulated and have the correct licensing. If ever you have questions, look for the UKGC (United Kingdom Gambling Commission) seal on the website. You should find the logo either on the About Us page or in the footer of the website.

How do I choose a platform?

Start with our suggestions, and then choose a website based on your needs. Learn what online slots you like to play, the bonuses you enjoy, and other factors that affect the experience. The more you know about what YOU enjoy, the easier it will be to find a service that matches these needs.

What are wagering requirements?

Often, special offers will come with wagering requirements, and this means that the bonus needs to be wagered a certain number of times before you can withdraw. When playing around the casino, be careful because not all games will contribute 100% towards the requirement.

Are there limits with slot games?

Yes, you’ll normally find time limits with bonuses and max win limits across the whole platform. Even if you win the progressive jackpot, website rules could mean that you walk away with a fraction of this amount.

What types of bonuses can I enjoy?

When it comes to slots, the basic bonuses are called wilds – here, your chance of winning increases. Variations include stacked wilds, expanding wilds, and sticky wilds. Other bonuses include multipliers and scatters.It’s time to go out there and have some fun in the world of online slots!
