    Slots are a fun way to pass time - and you might win big!

    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.

    The Evolution of Slots


    Slot machines have come a long way since they were first created in 1887. The original machines used cards as playing symbols and paid out prizes such as free drinks and cigars. 

    Over the years, the machines evolved to add more sounds, more prizes, and more exciting symbols to make them enticing to players. Mainly found at bars and gambling halls, slot machines quickly became a hit.

    In 1964, the first fully electronic slot machine was released on casino floors by Bally. The machine was called Money Honey and the one-armed bandit could pay out up to 500 coins as a jackpot prize.
    With the creation of the internet, online casinos quickly took to the web and in 1996, the first online slot was released by WMS Industries. Reel ‘Em drew players from all across the net and software providers realised that this would be the future of playing casino games.

    Now, many years later, online slots are more than just casino games. Vibrant graphics, exciting themes, and mind-blowing jackpots are available on thousands of games. Online slot creators are always pushing the boundaries of what could be the next big thing when it comes to slot features and rewards.
    It’s an exciting time at online casinos and it should not be missed!

    Popular Types of Online Slots


    Online slots are so much more than just reels and features. There are a number of different types of slots that can be enjoyed. From new slots that are released frequently to Vegas slots that are popular on casino floors, and so much more.

    Take a look at the most popular types of online slots you’ll find at casinos today.

    New Slots


    New slots are launched almost every day and with so many game providers around, it can get a bit overwhelming.  How do you decide which game to choose and where to play it? How do you find the best offers that let you try the game out. Which casinos offer free spins on that game?  Whichcasino.com makes it easy; simply head over to our New Slots section where we review all new releases and find you the best casinos to play them along with any special bonuses that might be available. 

    Vegas Slots


    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.

    Classic Slots


    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.

    Megaways Slots


    Megaways is a genre of games built with Big Time Gaming's Megaways technology. It's one of the most popular game engines out there - and has now been baked into many iconic games. The excitement of Megaways is that each betting round is different from the last. On one spin, you could only have a chance to win a couple of hundred ways. On another, you may be able to form lucrative combinations on 117,649 ways to win!

    Online Slot Features


    As online slots evolve and software providers aim to make them better and better, it’s important to understand features that are added to make casino games more exciting. Here are few key features to online slots that you should know more about.

    • RTP – The Return to Player percentage (or RTP) is a hypothetical rate at which online slots could pay out wins over its lifetime of spins. The higher the RTP, the lower the house edge and the more chance you stand to win.

    • Volatility – Also known as the variance, this aspect of online slots can help you determine which slots will suit your budget best. High volatility slots pay out large sums less regularly while low volatility slots pay out small amounts more often. 

    • Paylines/Ways to Win – Paylines or ways to win will vary from slot to slot. These paylines are the number of lines available for you to bet on. They can range from 10 to 7000 ways to bet on a single slot.

    • Free Spins – One of the most popular bonus features found on online slots, free spins give you the chance to play without spending any cash. Triggered by landing certain symbols on the reels, free spins can often be retriggered for more ways to play for free.

    • Multipliers – This feature is a great way to boost your bankroll with ease. Multipliers allow you to double, triple, or even quadruple your win by triggering this feature. Many slots offer multipliers and can even go as high as 50x your bet or more!

    • Wilds – One of the most popular features found on most online slots, Wilds come in many different shapes and forms. Expanding Wilds, Stacked Wilds, Sticky Wilds, and Shifting Wilds are all forms of this feature available. Check out the game’s info section for more information about the Wild feature, how it can be triggered, and how it will work.

    • Scatters – These bonus symbols are often used to trigger special games such as free spins when playing an online slot. Scatters can also have extra bonus uses but this should be explained in the slot’s info section.

    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.

    Online Slots Bonuses


    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.
