You’re probably wondering how something so simple can be so attractive to so many casino players. The bright flashing lights, sound effects and amazing animations and endless range of cool themes make online slots one of the most entertaining options at an online casino. Still not convinced? The allure of turning small stakes into huge jackpot wins is enough to entice just about anyone.

If you’re new to the world of slots or you’d just like to find out a bit more, our quick introduction to online slots for beginners is the perfect place to start.

Everything you need to know about online slots

The Basics

Once you’ve signed up with your favourite online casino, you’ll need to learn how to play slots if you want to stand a chance at winning big. Simply load up the online slot of your choice, you’ll be presented with a game screen filled with up to 5 reels. These reels will have a number of symbols on them, often related to the theme of the slot. There are a huge number of themes to suit all kinds of players, from classic fruit machine themed slots to eye catching 3D slots with top of the range graphics. The aim of the game is simple - spin the reels and land matching symbols to win. If you’re not sure how much you can expect to win, don’t worry, most casino games have a ‘paytable’ that usually lists all the need-to-know information, including payouts.

How to play online slots for real money

  1. Choose a top online casino
  2. First things first, you’ll need to pick out a casino to play at. You’ll want to choose a casino that features an extensive collection of excellent slots games from the top software providers such as NetEnt, Microgaming and Playtech, as well as slot specialists Play’n Go . Table game enthusiasts should look out for the coverage of casino classics such as roulette and blackjack, as well as live casino gaming options. Not sure where to start your search? Let us give you a nudge in the right direction with our handpicked list of the best online casinos. The sites that have made our list feature all of the above, plus some of the best bonuses and promotions you’ll find at online gambling sites today. You can relax and play at these sites knowing that you’re getting an unrivalled casino experience from the most trustworthy, legitimate casino brands on the market.
  3. Sign up
  4. Once you’ve picked out your favourite casino from our list, simply follow our link to register an account and become eligible for your exclusive welcome bonus
  5. Deposit to claim your welcome bonus
  6. Once you’re all signed up and your account is verified, you can make your first deposit at the cashier to claim your welcome bonus. Just about every online casino accepts the usual debit and credit card options, but the best casinos accept PayPal too. Don't forget to opt-in if you want to claim the welcome bonus- the best slot sites have plenty of free spins bonuses to help get you started.
  1. Practice on free online slot games
  2. Now that you’ve signed up and claimed your bonus, you’ll be eager to head straight for the slots and get your first spins in. While the game is incredibly simple to play, if you’re an online slots novice, we’d recommend trying a few practice spins before risking your hard earned cash. Many of the best online casinos allow players to play demo slot games for free. This is a great way to get familiar with the game and its various features and controls. Once you’ve learned the ropes, you can switch over to a real money game within seconds for a chance to spin and win big!
  3. Play!
  4. You’ll be able to choose from hundreds of the best slot games at the best online casinos, from old favourites to the hottest new titles. There’s a slot out there for everyone, from high rollers to fans of immersive 3D slots. Simply have a browse and spin the reels on the game of your choice. Your next win could be just a few clicks away!

Types of Slots

With thousands of slots available online, there’s bound to be a bit of variation. The top online casinos make sure there’s a slot game for everyone. When you head over to your chosen casinos slot collection, you’ll find three main variations. You’ll be able to choose from: classic three-reel slots, five-reel video slots and the hugely popular progressive slots. 

Progressive slots have jackpots that increase each time the game is played, so lucky winners can expect to earn life-changing sums of money. Progressive jackpot games such as Mega Moolah have seen huge eight-figure payouts to lucky players in the past.

Bonus Features

As if landing matching symbols across your reels wasn’t exciting enough, some of the best online slots games throw in some great bonus features to spice things up a bit. The top features include wilds, scatters, multipliers and free spins. 

Wilds are special symbols that appear in place of other symbols, make it easier to spin and win. You can usually trigger free spins or other bonus features by landing three or more scatter symbols. These free spins allow you to play bonus rounds without wagering any real money for your spins. Finally, multipliers, as the name suggests, give your payout a huge boost. 

Time to Play!

Now that we’ve taken you through the ins and outs of online slots, you’re ready to head to the casino and spin the reels! Not sure where to play? You’re sure to find your best bet from our carefully curated list of top online casinos. It’s jam-packed with casinos that offer the best games, promotions and bonuses you’ll find online. Simply compare and sign up to claim your exclusive welcome bonus today!

Your Questions Answered

Do online casinos give players free spins?

Yes, most top online casinos will offer free spins in some form. New players often receive no-deposit welcome bonuses, which come with free spins, while existing players are usually rewarded for their loyalty with free spins.
Playing on slots with the highest payout percentage is always a good move. Return to player (RTP) determines how much of your investment will be returned to you. The majority of online slots have an RTP of over 90%, but the very best slots payout 95% and over - keep an eye out for these. You could also look out for progressive slots with huge jackpots. While these don’t pay out as frequently, you could end up winning a life-changing sum of money.
A slot machine that features a progressive jackpot. This jackpot increases each time is played, but the jackpot is not won.
Yes. Every casino on our list has a mobile-friendly site, and the best even have mobile casino apps. This means you can play slots on the go, whether you want to play on your mobile or tablet!
Yes, online slot machines use a random number generator (RNG). This is an algorithm that randomly selects numbers, which are connected to a symbol. This ensures the results are entirely random and eliminates any chance of players using skill or experience to try and beat the house when playing online slots.
Of course. The best new casino sites feature a range of different games, including slots, online blackjack and online roulette.
