In many ways, slots are the backbone of the online gambling industry. They’re by far the most common casino game available online today and they’re arguably the most popular. They come in pretty much every kind of theme imaginable and have all sorts of exciting and creative features to keep you coming back for more. Here are some of our favourite games:
The typical online casino has several hundred slots available to play - in fact, some of the best have over a thousand. Since online slots are so diverse, the typical slots collection is suited to every type of player. There are three main types of slot: video slots, classic slots and progressive jackpot slots. You’ll find that most online casinos have a good mix of all three.
The way slots work is quite simple indeed. There’s a reel set with a number of rows and columns (or reels). You’ll find that most slots released these days have three rows and five reels. Each position is occupied by a symbol, so most of today’s slots have a total of 15 symbols displayed on the reel set. There are usually at least half a dozen different symbols that can appear on the reels.
When it comes to playing, you simply click to spin the reels. Once the reels have spun and come to a stop, any wins are paid out. In order to win, you need to land enough matching symbols on an active payline, which is a line going across the reels, usually from left to right and starting with the leftmost reel. Paylines include one symbol for every reel and the number of paylines varies greatly. Landing certain symbols may also trigger bonus features.
Betting values vary greatly depending on the slot you’re playing, as do payouts and jackpots. Some slots pay out more frequently than others and some are likely to pay out more money than others. Most slots let you play for as little as 1p, so if you’re on a budget, you’ll still find many slots you can play. Of course, you can always play free slots online.
To attract new players and keep existing players coming back for more gaming fun, casinos routinely offer all kinds of promotions. Many of these involve online slots bonuses. For example, welcome offers for new players usually reward you with free bonus money that you can use on slots (as well as other casino games) and/or some free spins to use on some of the casino’s slots.
A lot of casinos have ongoing or limited-time promotions involving their most popular slots, or the most recently released ones. Popular slots are often the focus of promotions because they’re more likely to encourage players to take part and play. The same can be said for new slots, especially if they’re a big-name release by one of the leading providers. Slot game reviews are always useful to find out about new games.

The term ‘Vegas slots’ basically refers to high-quality, modern video slots. You won’t come across this term too often - many casinos simply refer to these slots just as ‘slots’ or ‘video slots’. The reason some call them ‘Vegas slots’ is because they’re designed to replicate the Las Vegas gambling experience.
Of course, these slots are named after the desert gambling mecca of Las Vegas known for being one of the world’s top gambling destinations. It’s home to some of the largest casino resorts and has countless gambling opportunities available, including thousands upon thousands of slot machines.
Online Vegas slots are intended to let players all over the world experience Vegas-style gambling for themselves. These slots are typically immersive and detailed, with high-quality graphics and sound effects, plus lots of exciting gameplay features.
These slots are based on the earliest version of slots: the physical slot machine, or fruit machine. This gaming machine had a large drum with three reels and a single row where you’d have to match symbols to win. There was also a large lever to the side that you’d have to pull to spin the reels. You would be surprised to find out that these games had some interesting slots strategy.
Over the years, these machines became more advanced, eventually incorporating video screens, before online slots started getting developed. Online versions of classic slots typically have just three reels and few, if any, special features; many of them are themed after fruit machines and have various fruits as symbols. Nowadays, games can be as grand as Conan slots - with multiple bonus features, free spins and 3D graphics.
Progressive Jackpot Slots
Of all casino games, it’s the progressive jackpot slots that are responsible for paying out the highest cash prizes. What sets these slots apart from others is that they don’t have a set jackpot. Instead, their jackpots grow each and every time you place a wager. The more you wager and the more other players there are placing wagers, the more the jackpot grows.
Since there’s no upper limit on the jackpot, it can get very high indeed. Some progressive jackpot slots wins, such as Microgaming’s Mega Moolah and NetEnt’s Mega Fortune, have been known to pay out eight-figure sums to incredibly lucky players. We suggest checking those out.
Most casinos offer a minimum of 150+ slots to choose from and the obvious question is - which ones should you try? Our Slot Review page has a list of popular games and has been reviewed by our team. Starburst, Rainbow Riches, Book of Ra and Narcos are just some of the slot game reviews you can find here.
Sure, slot games are a mostly solitary experience. But they don't have to be when you join a slots tournament. In these type of multiplayer competitions - you're not just aiming to win big on the reels. You are also aiming to beat your competition to a top place on the leaderboard.
