What are Online Slots?
This is an easy question to answer! Online slots are the digital version of slot machines that you'd find in a land-based casino, retail betting outlet or pub.
To start playing a slot game, all you need to do is set your bet amount and click on the spin button to get the reels moving. Symbols will land and if you get a winning combination, the money will be added to your online casinos account automatically. There's no real skill to playing slot games because they all work with Random Number Generators, so the outcomes can't be predicted or changed. More about that later.
There are tons of different kinds of online slots out there - just like land-based casinos have all sorts of slot machines. Some online slots take inspiration from classic games and feature symbols like bells, sevens and bars, while others have modern themes like adventures or animals. They can even come with special features including bonus rounds and multipliers.
Some slot games also come with a progressive jackpot feature, where a small percentage of each losing stake contributes towards a prize pot. These games can pay out six or seven figures in dollars, pounds or euros.
How to Play An Online Slot Machine
Use this free interactive demo to learn exactly how an online slot machine works. No real money is involved at any point, you cannot win or lose any cash. The demo credits you see are entirely fictional and exist purely to help you understand how stakes, paylines and payouts work before you ever consider playing for real. Follow the steps below and try it for yourself!
Step-by-step guide
Before spinning, decide how much you want to wager on this spin. The amount you choose is your total stake and covers all 9 paylines automatically. A higher stake means bigger potential winnings, but also a bigger cost per spin.

Key concepts to understand
Every spin is independent and random. Past results have no effect on future spins. There is no strategy that changes what the reels land on. Real slot machines use a Random Number Generator (RNG), a computer system that produces thousands of random numbers per second. The moment you press spin, the RNG selects a number that determines exactly where each reel stops. Real money online slots are independently tested and certified by regulatory bodies such as eCOGRA and iTech Labs to ensure the RNG is genuinely random and the game operates fairly.
Return to Player (RTP) is a percentage that tells you how much of the total money wagered on a slot is paid back to players over time. For example, a slot with a 96% RTP will, on average, return $96 for every $100 wagered across a very large number of spins. It is important to understand that RTP is calculated over millions of spins, so it does not predict what will happen in a single session. You could win big or lose your budget quickly regardless of a game's RTP. Always check a game's RTP before playing, it is usually found in the game information or rules section. Higher RTP games generally give you better long-term value.
Always set a budget before playing and stick to it. Only ever bet money you can afford to lose and treat any winnings as a bonus rather than an expectation. It helps to decide on a loss limit before you start, so you know when to stop. Chasing losses is one of the most common and costly mistakes when gambling online. Slots are designed for entertainment, not as a way to make money. If you feel that gambling is becoming a problem, free help and support is available through organisations such as GamCare and BeGambleAware.

How Do Online Slots Work? Random Number Generators
The most important thing to remember is that slots are based on chance, so there's nothing you can do to change the outcome. This means that, unfortunately, we can't tell you how to win online slots.
Random Number Generators (RNG) are essentially computer algorithms which are constantly generating numbers, corresponding to a certain combination of symbols on the reels. As such, the symbols landing on the reels are already predetermined by the RNG, meaning they can't be influenced by the player, the casino or the software provider that makes the game.
RNG also means that every single spin is totally independent, so there's no such thing as a slot being "hot" or "cold" and playing at a certain time of day doesn't give you a better chance of winning.
Reels and Paylines
Picture the game grid on a slot. It's made up of a series of vertical reels and horizontal rows, which are where the symbols land when you click on the spin button. Most modern video slots have five or six reels, while retro-themed games usually have three. The number of rows can also vary but it's typically between three and seven.
Paylines are the patterns on the grid where matching symbols need to land, to trigger a win. Some games have 10 or 20 fixed paylines, while a lot of more modern games do away with paylines in favor of "ways" or Megaways, which tend to give you more opportunities to land winning combinations.

Multipliers, Scatters and Wilds
While retro-style slots focus on simple gameplay, modern titles come with lots of different special features which are triggered by specific symbols. Most slots have a "wild" symbol which can land at any time during gameplay, and this substitutes for other regular symbols (not scatters) to help you complete winning combinations.
Scatters are special bonus symbols which usually open up a bonus game (like a free spins round) when enough of them land on the reels. Scatters come up less often than regular symbols. Finally, slots can have multiplier symbols which can increase your wins and sometimes these accumulate during bonus rounds, for even bigger payouts.
Make sure you only ever play at a licensed online casino, for example one regulated by the UK Gambling Commission if you're in the UK, or by your state's authority in the US. Licensed casinos offer games that use RNG and are certified as completely fair.
How Do You Win Real Money Playing Online Slots?
As we've mentioned, Random Number Generators determine which symbol combinations land on the reels whenever you spin, so we can't tell you exactly how to win online slots. Each slot game has a slightly different payout mechanic, so make sure you check the paytable before you spin.
Most slot games work with paylines, so you'll need to match a certain number of the same symbols on adjacent reels from left-to-right on one of the paylines to trigger a win. Most slots have high and low-value symbols, so the amount you win will depend on which symbols land in your winning combination. Some games have other mechanisms like Megaways, which we'll explain later.
Bonus rounds are another great way to win in slot games. A lot of titles have a free spins round where you'll be awarded anywhere from five to 20 free spins at the same bet level as the spin that triggered the feature. Free spins rounds often come with extra features like multipliers, which can make them even more attractive.
Understanding Stakes
Understanding the stake amounts on a game and setting your bets to suit your budget is one of the most important skills to master when looking at how to win online slots. Although the games are totally fair and you can't influence whether or not you win, you can influence how quickly you run through your bankroll.
All games give you a range of different stake options. Some retro slots have a minimum bet of as little as $0.01 per spin, but most modern games set the minimum at $0.10 or $0.20. The maximum can vary depending on your region (at UK online casinos it's £5 per spin, for example), but slots generally allow you to bet for up to $20, $50, or even $100 per go.
How to Win Progressive Jackpots
As we've mentioned, progressive jackpots are very special slot games where the prize pots increase every time someone plays anywhere in the world. This means that the jackpot prizes can easily reach into the millions of dollars or pounds. Some of the best progressive jackpots include the Mega Moolah and Age of the Gods series.
Progressive jackpots can usually trigger randomly on any spin, making for very exciting gameplay, although it's often more likely that a jackpot will trigger with a higher stake value. Sometimes a special wheel will appear and you can spin it to see which prize you'll receive. Remember, RNG applies to progressive jackpots too, so there's no skill involved.

How to Win Megaways Jackpots?
Megaways is a relatively new concept in online slot games, but it's become very popular very quickly. Rather than having a set number of rows with symbols appearing in the same places, Megaways games can usually show between two and seven symbols per row and this changes each time you spin. This creates thousands of potential winning combinations and makes gameplay exciting, because you never know what's going to happen when you spin.
There are a few slots out there that have the Megaways mechanic plus a progressive jackpot (Mega Moolah Megaways is one of them) and like other progressive jackpots, the payouts trigger randomly.
How to Choose the Best Slots
There are thousands upon thousands of slot games out there and new titles are released as often as every single week. It helps to know exactly what you're looking for so that you can choose the right game for you. We'd always recommend starting with high RTP games - slots that tend to pay out more than the industry average of 96%. You'll find the RTP on the game info page or within the paytable.
Think about the different slot game themes. You might want to start off with some retro-style games, but there are also tons of titles themed around everything from adventures and space to animals and ancient Greece. Everything including the symbols, the grid and the background music work together to create an immersive gaming experience.
Bonus features are another way to choose the best games. We're big fans of free spins and respins rounds and it's even better when they come with multipliers. We'd also strongly recommend trying out progressive jackpots - you just never know when you could get really lucky.
Some online casino sites have free slot demos which you can try before you commit to spending any real money. Use the demos to get familiar with the RTP, volatility and special features of a slot.
Online Slot Volatility and Payout Patterns
Slot volatility is something you might not have heard of if you're a casual player, so we'll break it down in easy terms for you. Put simply, it refers to how often the slot pays out and what size those wins tend to be.
Most slot games are ranked on a volatility scale: low, medium, or high. A low volatility slot game tends to pay out relatively often, but the wins are usually quite small. These games are a good option for newer players or anyone with a smaller budget, because you won't run through your entire bankroll too quickly.
High volatility slots, on the other hand, are a little more risky because they don't pay out too often, but wins can be a lot bigger. As you might have guessed, medium volatility games fall somewhere in the middle.
It's very important to read the paytable before you start to spin on any slot game. You need to understand the RTP, volatility and how the bonus features work, so that you can make good strategic choices.
Online Slot RTP Percentages and Slot Odds
By now you already know that slot games are fair and random, but does that necessarily mean they actually pay out?
Well, the first thing to know is that every game has a set Return to Player (RTP) percentage, which refers to the amount of money staked on a game, which should return over time. For example, an RTP of 96% means that for every $100 staked, $96 should return.
RTP is calculated over the course of millions of spins, so even a very high RTP isn't a guarantee that you'll win, but it's a decent indicator of how the game pays out. The industry standard for slot games is 96%, but there are a few titles (like Blood Suckers and Mega Joker) with an RTP of over 98%.
Remember to always manage your bankroll, so that you don't lose all of your money too quickly. This is one of the few actual strategies you can use on games of chance like slots. It's a good idea to only bet 1% to 2% of your total bankroll on a single spin.
Online Casino Welcome Bonuses
Online casino welcome bonuses offer a great way for you to play top slot games without the risk of losing your own real money. This is ideal if you're just getting started or you want to explore a few different games to try to find a new favorite.
Most online casinos have a little incentive for brand new players and these bonuses vary a lot depending on the casino and the region. For example some US casinos offer cashback on your first day's losses, while simple deposit match bonuses are popular in the UK. Sites licensed in Malta or Curacao tend to have big bonuses like multiple deposit matches or hundreds of free spins.
We've listed a few of our top sites for you on this page so you can browse and find a welcome offer that suits you. Make sure you sign up via a link at Bookies.com and use our special casino promo codes if needed.
Before you claim a welcome bonus, you'll need to understand the T&Cs. As an example, deposit match bonus offers tend to come with wagering requirements, while free spins bonuses might have a strict time limit or a maximum cashout value. When you understand the T&Cs, you can really make the most of your bonus.
Where to Play Online Slots
Before you can start enjoying slot games, you'll need to choose the right online casino for you. Remember, all casino fans are different so what you're looking for in a site might not be exactly the same as what others want - but we have a few guidelines for you to follow.
The first thing to look for is a valid license. This is non-negotiable. If you're in the US, the casino needs to be approved by your state's gambling authority, while in other countries you can look for licenses from the UK Gambling Commission, Malta Gaming Authority or Government of Curacao.
Next, look at the selection of games. You'll want to see at least a few hundred (ideally over 1,000 titles) including Megaways games, progressive jackpots, new online casino slots and maybe even some live casino tables. Bonuses are another important feature of an online casino. Look for generous welcome offers as well as promos for regular players, for example free spins, loyalty rewards or a VIP scheme.
If mobile play is important to you, you'll want to make sure that there's either a downloadable app or an optimised mobile website so that you can always play on the go. Finally, check all of the smaller aspects of the site. Have a play around with the navigation, see if there's 24/7 customer support and check what payment methods the site accepts.
Recommended Online Slots Software Providers
When you check the lobby at your preferred online casino, you might be overwhelmed by all the different software providers. There are few to check out immediately if you need some inspiration.
Games Global is a major powerhouse in the world of online casino games, known for their big progressive jackpots including the Mega Moolah series. While if you're looking for fan favorites that have stood the test of time, NetEnt games like Starburst are a great option.
Fans of special features like Megaways and Multipliers should opt for Pragmatic Play titles like Gates of Olympus and Sugar Rush 1000, which also come with fantastic graphics. If you're more of a mobile player, check out Hacksaw Gaming slot Bash Bros which is designed with app play in mind.
Recommended Slot Games to Try
- Starburst: This is a NetEnt classic with wilds, a respins round and a "win both ways" payout mechanism.
- Big Bass Bonanza: Reel in fish money symbols during the free spins round to win cash prizes!
- Eye of Horus: With wilds and free spins, this ancient Egyptian game is a thrill ride.
- Fishin' Frenzy: This simple game comes with five reels, 10 fixed paylines and plenty of ways to win.
- Mega Moolah: You might just take home the progressive jackpot when you play this Games Global slot.
- Bonanza: This game was the original Megaways slot, with up to 117,649 ways to win.
Make sure you don't get stuck with the same old slot games! New titles are released all the time, so head to the new games section in the lobby and start spinning on some brand new titles.
Responsible Gambling
Playing responsibly is key when you're exploring online slots. The first thing to do is set yourself a budget and make sure that you never spend more than you can afford to lose. Licensed online casinos have tools like deposit limits, session time limits, reality checks and self-exclusion, which can be a big support.
If you need any more help staying in control, you can check your online casino's responsible gambling section, or consult a resource that's available in your area:
Final Thoughts
All slot games are different and they pay out in different ways: paylines, Megaways and progressive jackpots are just a few of these. It's important to understand basics like the game's RTP, volatility and bonus rounds, so that you can fully enjoy your gaming experience.
Most importantly, remember that slots at licensed online casinos use Random Number Generators, so they're completely fair and you'll have a real chance of winning (but never a guarantee). Be sure to always play responsibly - and have fun!
