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
    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?

  4. Practice on free online slot games
    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!

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, making 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.
