Rules – How Do Online Slots Work?

Understanding the rules of online casino slots is easy – you simply need to know what the different elements mean so that you can place your bet efficiently. Below, we’ve explained all the essential parts of a typical slot machine:

  • Pay Table – this lists the symbol combinations that result in a win and the size of each prize;

Types of Online Slots Games

We’re now going to look at the main types of slot games. Each has its own charm and features, so think about what you want from your gaming experience.

By Type

Classic slots are the simplest games, while video slots often come with multiple bonuses. Progressive slots feature a continuously rising jackpot. Here’s a short explanation of these categories:

  • Classic Slots – These online slots UK (and the rest of the world) typically have 3 reels and between 1 and 5 pay lines. They often feature retro fruit symbols and are great for beginners.
  • Video Slots – Also known as ‘multi-line’, these games have 5 reels and often more than 10 pay lines. Many include cinematic-quality graphics, themed bonus rounds, and even tricks reminiscent of video games, such as ‘levels’ and ‘lives’.
  • Progressive Slots – This type features a continually increasing jackpot. A small percentage of each wager made by players goes towards raising the maximum prize. As a result, this can build up to enormous heights over time.

Not sure which way to go? Why not try one of each? This will give you a feel for which type of game you enjoy the most. And remember, many online casinos change regularly, so there’s always something new to try.

By Software Provider

Another factor to consider when picking a slot is the software provider behind the game. Each developer brings something unique to their creations. For example, NetEnt slots tend to come with innovative functions and spectacular visual effects. Meanwhile, Microgaming is famous for creating many lines and high RTP rates.

Do some research to discover providers that release the types of slots you enjoy. Our slot reviews here on AskGamblers can shed light on the topic. We also suggest trying out demo versions to compare providers directly. 

If you don’t have a preference already, allow us to present you with a list of the top 10 online slots software developers in the world. Who knows? Maybe you’ll end up being their biggest fan:

These are only a handful of the leading names in the business. Many others produce excellent games too. With a bit of experimentation and reading through our slot reviews, you’re sure to find a software provider that suits you.

By Features

Online slots free play versions and real-money variations come with numerous extra features. These range from simple to complex and can greatly enhance your gaming experience. Here’s a rundown of what you can expect to find:

  • Wild Symbols – These replace other pictures to help create winning lines. Most slots have at least 1 wild. Some also include walking or expanding wilds, sticky wilds, and other variants with special properties.
  • Scatter Symbols – Usually, landing 3 or more scatter symbols triggers a bonus, such as free spins. These symbols can be in any position on the reels to count, sometimes they even pay a coin prize.
  • Multipliers – These increase the size of your prize when you score a winning combination. Often, the higher wager you place, the bigger the multiplier will be.
  • Free Spins – A popular feature, this allows you to spin the reels without spending any more money, giving you the chance to win cash without risking your stake. Free spins often come with multipliers and other perks.
  • Bonus Games – Many themed slots include mini-games that transport you into a different screen, often with a different layout and controls. Bonus rounds can be triggered in various ways and deliver a thrilling break from the base game.
  • Progressive Jackpots – A constantly growing sum of money won by players collectively not winning it. Usually, to have a shot at winning the progressive jackpot, you will need to place the maximum bet.
  • Tumble or Cascading Reels – Rather than spins, these games use a mechanism where winning symbols disappear and are replaced by new ones, which can lead to multiple wins from a single wager.
  • Megaways – A trademarked term used by developer to describe a slot machine that features more than one symbol that can land on a single space. Those slots normally have a huge number of paylines, ranging from 117,649 (Gordon Ramsay Hell’s Kitchen) to a mind-boggling 1 million ways to win (Blue Wizard). 

Of course, slots with additional features generally have a lower RTP than those without. That’s because these extra elements bring something extra to the game, allowing for larger prizes and more excitement. Many players prefer to play slots with bonus rounds, progressive jackpots, and so on since these features add a new level of fun to the mix.

However, if you prefer a simpler experience, opt for a classic slot with high RTP and no added extras. There really is something to suit every taste in the world of online gambling. So don’t be afraid to test the waters and see what works for you.

Our advice would be to start with slots with free spins and demos to get a taste of how the bonus games work. It’s also important to mention progressive jackpots here. While these prizes can reach enormous sizes, there are usually strict requirements regarding bet size in order to be eligible to win them. Make sure to check out our guide to progressive jackpots for more info on this particular feature.

Online Slots Software Testing Agencies

The role of agencies testing online gambling software is to ensure fairness and prevent fraud within the industry. These organisations carry out rigorous tests on Random Number Generators (RNGs), ensuring that the results produced by slots and other games are truly random and unbiased.

In addition, they assess whether the software behind a slot is functioning properly. This includes checking that the game plays as it should, pays out correctly, and provides an enjoyable experience for players. When an operator’s platform passes these checks, it is awarded a certificate, which is usually displayed prominently on the casino site.

Below, you can find the logos of some of the most reputable testing houses in the industry. These companies are globally recognised for their expertise in ensuring fair play in online gambling:

Agencies Testing Online Gambling Software

  • eCOGRA
  • iTechLabs
  • Technical Systems Testing (TST)
  • Gaming Laboratories International (GLI)
  • Fraud Labs Pro
  • Quality Module Testing (QMT)

When you see the logo of one of these agencies on an online casino, you can trust that the site is legitimate and that its games are fair. At AskGamblers, we only review and recommend sites that have been certified by reputable testing agencies. So, if you come across a casino that isn’t accredited, it’s probably best to give it a wide berth.

How to Improve Winning Chances

There’s no magic formula to winning at online slot machines, but there are some tips that could improve your odds to some extent:

  1. Pick a Slot with a High Return to Player Percentage (RTP) – This indicates how much of each wager goes back to players over the long term. The higher the RTP, the better. As a rule of thumb, aim for a game with an RTP of 96% or higher.
  2. Set an Hourly Time limit – Rather than setting a budget, set yourself a time limit of, say, 1 hour, and treat it like you would treatment for sleep apnoea. This will prevent you from chasing losses and help keep your spending under control. After all, it’s possible to go through even the largest bankrolls when playing online video slots.
  3. Take Advantage of Welcome and Other Promotions – Sign up to casinos offering generous bonuses and promotions, including welcome offers like free spins or a matched deposit bonus. Just make sure you read the terms and conditions carefully before claiming a promotion.
  4. Look Out for Games with Free Spins – Not only are complimentary turns on the reels fun, but you also get to win without wagering any stakes. Many slots also include free spins as part of their gameplay, activating them when you land three or more scatters, for instance.
  5. Try Free Slots Demos – This is one of the best ways to prepare yourself for the real thing. Virtually all online casinos offer demo modes, allowing you to play slots using virtual funds provided by the site, giving you a true-to-life experience of the game. Plus, you’ll get to test out bonus rounds and other features first hand. But keep in mind that playing a demo does not guarantee any real-world success, unfortunately.
  6. Choose In-Game Bonuses Carefully – While it can be tempting to grab every bonus that comes your way, many have strict requirements, such as having to wager your winnings a certain number of times before you can withdraw them. So, be sure to read the T&Cs to avoid ending up disappointed.
  7. Close All Unused Pop-Ups – Game enhancement pop-ups can slow down your PC, making it run sluggishly. To ensure optimal performance, close all unused pop-ups to reduce lag and keep your device running smoothly. Trust us – this can significantly enhance your overall experience with online video slots.

Will they guarantee success? No. But these hints could certainly give your slots sessions a healthy boost. Furthermore, we suggest testing these out on free slots first. See which strategy works best for you personally. Remember, playing slots should always remain a form of entertainment rather than a way to earn quick cash. 

Have fun exploring these tips, and who knows? With a little luck on your side, you might just hit the jackpot! Now, let’s move on to answering the next frequently asked question: how to pick a slot game?

With thousands of options to choose from, deciding which slot to play next can be tricky. To help you out, below, we’ve outlined some key points to think about when browsing an online casino:

How to Pick a Good Online Slot Machine?

  1. Consider the Theme – Would you like to travel back in time, explore enchanted forests, or meet superheroes? Many slots are based on TV shows, movies, comic books, and other sources of pop culture, so think about what floats your boat. Alternatively, you could go for a classic slot featuring traditional pictures, such as fruits and bars.
  2. Think About Mobile Optimisation – Most people play online slots on smartphones and tablets. So, check if the game you’re considering is fully optimised for mobile devices, with touchscreen controls and clear graphics.
  3. View the Video Preview – The best casino sites allow you to watch videos of slots in action. Take advantage of this to get a feel for the gameplay, bonus rounds, and theme. This can be especially helpful if you’re comparing several slots against each other.
  4. Read the Game Rules – This may seem dull, but doing so helps you understand exactly how a slot works, including any unusual bonus rounds. You’ll be able to tell straightaway if the game is for you or not.
  5. Check the Technical Details – Look up the volatility, RTP rate, payouts, and which software provider developed the game. Compare these details across several slots to find the best matches for your preferences and playing style.
  6. Test Drive a Free Version – Once you find a slot that appeals to you, try the demo mode to see if you enjoy the gameplay and bonuses. Bear in mind that the demo may be a shortened version of the game, so you should still read the rules first.

Online Slots vs at Land Based Casinos -- What's the Difference?

For those of you who have enjoyed spinning the reels of land based slots cabinets, you'll be happy to know that online variants follow the same general principle. Still, there are some differences worth mentioning, and we're listing some of the most notable ones below:

Online Slots vs Land Based Slots

  • Accessibility - Online slots are available 24/7, while land based options depend on the opening hours of a brick and mortar casino. 
  • Variety - Online venues host thousands of different slots, from classics to themed games, movie-inspired slots, and more. Bricks and mortar establishments typically have fewer choices, although this can vary widely depending on the venue.
  • Payouts – Both types of slots can offer big prizes, but progressive jackpots tend to grow much faster online, as they draw players from multiple casinos. In general, RTP rates tend to be similar, although individual variables (see below) can affect this.
  • Speed of Play – Online slots let you spin quickly, while land-based machines can get backed up, especially during peak periods.
  • Anonymity – No one will judge you if you sing along with bonus features in the comfort of your home. In a public setting, some players may cast disapproving glares your way if you act too excited!
  • Noise Level – Land-based slots come with flashy lights and loud sounds effects. Online, you can choose to mute or lower the volume on your favourite games.
  • Social Interaction – If you enjoy chatting to other players, land-based venues are superior when it comes to meeting fellow slots enthusiasts. 
  • Complimentary Drinks – It’s customary to offer free beverages to customers in land-based casinos, whereas online venues tend to focus on promotions such as bonuses and free spins.
  • Mobile Compatibility – Online slots are designed for smartphone and tablet play, whereas land-based options require you to be in the vicinity of a casino. 
  • Safety – While both forms of slots are generally safe, playing online at a licensed site affords extensive security protocols, whilst in land-based casinos, you cannot help but notice an occasional cheater getting thrown out.

Ultimately, each format has its pros and cons. Land-based slot machines provide an authentic, sensory experience, while the online alternatives boast broader choice, faster action, and accessibility. Whether you choose to play in a casino or from home, both formats offer thrills, excitement, and the chance to hit the jackpot!

If you're interested in learning , we got you covered - head over to our blog post for a comprehensive overview of this process. Believe it or not, slot machines were not always self-operated, so that's another interesting topic we'd love to dedicate a separate blog post to! Until then, feel free to drop us a comment below with your thoughts on online vs land based slots!

Demystifying Common Myths

Now that you know how to play online slots, let’s address some common misconceptions surrounding these games:

Myth 1: "A slot machine is due to payout."

Fact: This is not accurate. Every spin is conducted independently by an RNG, meaning each outcome is random and not affected by previous results. So, a slot hasn’s knowledge of your balance will not make it payout more frequently or generously.

Myth 2: "Max bet is the way to go."

Fact: Whilst playing at the max bet will give you a shot at winning the progressive jackpot (if the slot is categorised as a progressive one, that is), it is not a requirement. You should always set a budget that feels comfortable for you, and stick to it, regardless of the value of your wager.

Myth 3: "You can beat slots by using a particular strategy."

Fact: Whilst there are lots of guides to playing slots ‘properly’, none of them can guarantee winnings. These games are designed to be random and unpredictable, so no matter what you do, you cannot influence the outcome of a spin.

Myothing 4: "Online slots are just for older people."

Fact: People of all ages play online slots, from teenagers to retirees. They offer something appealing to a broad audience thanks to their diversity, accessibility, and potential rewards.

Reasons Why Online Progressive Slot Jackpots Are Better Than Land Based

Mything 5: "All online slot sites are the same."

Fact: There are countless operators out there, each offering a unique selection of slots alongside bonuses, VIP programmes, payment methods, and more. Whilst they all provide slot machines, it’s worth shopping around to find the one that is right for you.

By understanding these points, you’ll be better equipped to approach your slots adventures with a level head and appreciate these games for the entertaining form of gambling that they are. 

What About Payouts & Contribution to Online Casino Revenue?

Online slots are extremely popular, but do they contribute the majority of revenue to online casinos? The answer is yes. These games account for more than 70% of income at the !

They are preferred by players thanks to their simplicity compared to , for example. Furthermore, slot machines offer the chance to win large sums of money, including life-changing jackpots. Many gamblers are attracted by the prospect of hitting the big time with a small wager.

When it comes to payouts, online slots share some key features that can help you spot the most generous games. Namely, they rely on two key statistics:

  1. The RTP Rate - This tells you how much of each wager goes back to players over the long term. For example, an RTP of 96% means that $96 is returned for every $100 staked. Whilst there are tons of slots with differing RTPs, you should aim to play those with a rating of 96% or higher. 
  2. The Volatility - This measures how often a slot pays out and what size the prizes are. Low volatility slots dish out regular, smaller wins, while high volatility titles are riskier, but can award massive payouts. Mid-volatility games fall somewhere in between, delivering a nice combination of frequency and size.

How to Keep Track of Results in Excel

Some players like to keep detailed records of their slots sessions, tracking data such as wins, losses, average bets, and session lengths. If you relate to this, one handy tool for organising all this information is Microsoft Excel.

Here’s a simple method for keeping track of your slot results in Excel:

  1. Open a new blank workbook.
  2. Click on the ‘Tab’ button at the bottom of your screen to add tabs.
  3. Add a tab for each stat you wish to monitor, such as ‘Wins’, ‘Losses’, ‘Total Spins’, ‘Average Bet’, and ‘Session Length’.
  4. On each tab, create 2 columns entitled ‘Date’ and ‘Result’.
  5. Enter some sample data to familiarise yourself with adding information.
  6. To input the date automatically, click on the first empty date cell, hit ‘Ctrl + Shift + ;’ on Windows (or ‘Command + Shift + ;’ on a Mac) to open the ‘Format Cells’ window. From here, choose ‘Date number’ (mm/dd/yyyy) and hit ‘OK’. Then, each time you click in a date field, it will display today’s date, which you can override with the current date for each entry.

Using this system, you can easily see your progress over time. You could even create charts and graphs to visualise your stats, identifying trends and helping you refine your slots strategy. It won’t guarantee success, but some players find it useful to monitor their play in this way.

Tips for Playing on Mobile

Follow these tips to get the most out of playing online slots on your mobile device:

Tips for Playing on Mobile

  1. Make sure you have a strong WiFi or data connection to avoid interruptions, buffering, and other issues that can disrupt your gameplay.
  2. Use the zoom in/out function to adjust the size of the reels to suit you. Some players find this helps with accuracy when placing bets andspinning the reels on a smaller screen.
  3. Take advantage of touchscreen controls. Whilst some slots merely use your tap to spin, others incorporate swiping, holding, and other gestures for added interactivity.
  4. Don’t play for longer than you intended. It can be difficult to tell how long you’ve been spinning slots on your phone, leading to overspending. Fortunately, most devices have clock widgets you can add to your home screen for easy reference.
