    You know the feeling when you find those best slots to play online for real money. It’s a feeling of excitement, anticipation, and satisfaction all rolled into one.

    Many players tend to be drawn to a couple of popular games. It’s always good to have a selection of slots to rotate between. This keeps things fresh and exciting. And, it also prevents us from staying on the same online slot for hours after it has been on a not-so-favourable streak.

    But how do we find the top alternatives? It takes some research and a bit of luck. Our aim is to help you on your way to finding the best online slots to suit your preferences. We’ll also point you to the biggest online casinos that offer the greatest slots of all time.

    Which are the most popular best casino slots online

    Online slot machines can be played on your computer, tablet or smartphone at any time, anywhere in the world. They work the same as land-based slots do: you deposit money, press the play button, and have fun playing the game.

    It’s this simplicity that makes slot machines so popular. And since we don’t have to head down to a land-based venue anymore in order to play, it’s that much easier to enjoy the best online slots whenever we feel like it.

    Let’s look at some of the biggest hits in iGaming. Placing a focus on what it is about each of the great slot machines that makes it so popular will help us understand a bit about the different features of online slots.

    The most popular online slots are ranked differently for various regions. There are many reasons for this. For example, some game providers aren’t licensed to offer slots in certain countries. So, a game that is wildly popular in one region may not be very accessible in another. Themes can also be a determining factor when it comes to the popularity of slots in different regions.

    However, there are certain casino games that definitely stand out from the crowd. These online slots are globally regarded as the best of the best. Players from all corners of the world flock to them time and again.

    Here are some of the most popular video slots along with the game providers that created them:

    No doubt you’ve heard of some, if not all, of these video slots. You’re in for a treat if you haven’t. These games serve up everything you could ask for on a silver platter: adventure, bonuses, wild symbols, and free spins galore. These are the key aspects of the best online slots after all.

    How to pick the best slots to play online for real money

    How to pick the best slots to play online for real money

    There are a number of key factors that can influence your decision when trying to find the best slots to play online for real money. The first step is to identify your priorities and then find the games that match them.

    Here are things to consider:

    reload Casino Bonuses icon

    Are there special promotions with different games? Online casinos offer different games at different times so it is worth keeping up to date with the latest promotions and giveaways related to different games.

    slot-machine icon

    It’s okay if entertainment is your top priority. If it is, be sure to pick online slots that offer amazing graphics and themes that appeal to you.

    deposit bonus

    Do you want the best value for your money? Then look at the game’s Return to Player percentage (RTP) to find the one with the best statistical value. Games with higher RTPs have a smaller profit margin (for the casino) in the long run.

    Slot icon

    The word volatility, as applied to an online slot, refers to the level of risk inherent in the game. It is used to describe how often and how much you can win during your gaming sessions. Games with high volatility can involve long periods of drought with the occasional big win.


    What the RTP Tells You about the best online slots

    An RTP tells you how much of all the money wagered on an online slot will be paid back to players over a period of time. The time period considered in the RTP calculation is in the long run and spans over millions of bets – so don’t be surprised when your slot session doesn’t pay you out according to the RTP stated.

    Every slot machine has its own RTP. The RTP is expressed as a percentage. The higher the percentage, the more often you can win money over a longer period of time. However, the value is a theoretical statistical calculation that cannot be taken literally. An RTP will give you the approximate overall estimate for the slot or game in the very long run. It cannot predict the outcome of your experience.

    Here are some of the best online slots with high RTP values that we can’t get enough of:

    Fruit Million97.1%
    Big Bad Wolf97.34%
    Steam Tower97.04%
    Jack Hammer 297.07%
    Joker’s Luck97.61%
    Jungle Stripes97.03%
    Book of 9999%
    Greedy Goblins97.2%

    If you’re going to play online slots based on their RTPs, always review a game’s RTP once you have opened it. You can view it by clicking on the information icon once the game has loaded. This is a precautionary step because some online slots are developed with a variable RTP range.

    Variable RTP ranges give online casinos the ability to set the RTP values to their liking. The best online casinos will leave the return percentages at higher values. But you will get some online casinos that do the opposite.

    Fortunately, casinos that are licensed by proper authorities, such as the Malta Gaming Authority, will never set their RTP rates at less than 84%. They usually keep them much higher, even on the highest RTP setting. You can bet that the sites listed on have been vetted to validate that they are properly licensed.

    What is the Volatility of an Online Slot

    High volatility online slots also have the ability to go on a winning streak and pay out a large number of big wins in a short period of time.

    On the other hand, games with low volatility typically pay out smaller wins on a more regular basis. Low volatility games mean less risk. The payouts on low volatility slots are smaller but much more frequent and there won’t be much time to get bored when playing this type of game.

    Small wins pop up every few spins and you are constantly entertained by all of the bonus features and animations that are keeping your attention. That’s not to say that big wins are impossible on low volatility online slots – they can, and will, happen. Volatility is also referred to as variance when speaking about online slots.

    Pro Tip: You can find out the volatility of the best online slots by checking the game provider’s website or by testing the game in demo mode. Playing slots for free in demo mode will help you determine if it pays out often or not.

    How the Best Online Slots are Kept Fair

    How the Best Online Slots are Kept Fair

    There’s a myth that all online slots are rigged. Of course, you do get online slots that are offered by dubious sites. But we’re not talking about those. We recommend that you steer clear of those sites and stick to the online casinos that we recommend. The outcomes of the online slots at these safe online casinos are determined by random number generators (RNGs).

    A random number generator is a computer algorithm that constantly generates a complex series of numbers that are used to determine the outcomes of slot machines and other casino games. The randomness achieved by this method is globally viewed as more than adequate for online gambling.

    With reliable online casino software, the RNG is built into every single game and is always operating. Here are a few interesting facts that give some insight on exactly how RNGs ensure the fairness of online slots:

    RNGs have been used in slot machines for decades and have improved significantly in recent years with advancements in computer technology. Nowadays they are more powerful and safer than ever.

    The RNG generates numbers between 1 and 10 digits long, one hundred times per second. Each of the numbers generated corresponds in some way to a symbol and a possible position on a reel.

    When you press the spin button, the game picks the numbers created in that millisecond to determine the outcome of the spin.

    The good news is that most slots have a free or demo version that allows you to test the game before playing for real money. Opting for the demo mode of a slot lets you use different strategies and familiarize yourself with the theme and the rules of the game without risking your money. On the other hand, you cannot win any real money or claim any of the bonuses. If you find a title that appeals to you, we recommend testing its demo mode, and then go for some real money play.

    Are the best Online Slots mobile-ready

    Are the best Online Slots mobile-ready

    If you like playing games on your mobile phone rather than on a desktop computer, you’ll have no trouble finding fantastic online slots to enjoy. We can easily play slots on smartphones and tablets running Android and iOS operating systems. Some of the best online casinos are also available on some Blackberry and Windows handheld devices.

    Depending on which mobile casino you choose, you may not even have to download and install any special software to play the games, deposit and withdraw, chat to customer support, or view your transaction history. Even the live dealer games are available on mobile without any download required.

    There are a few online casinos out there that are staying with the download method – on handheld, desktop, and laptop devices. Some players prefer downloading and installing software, and there’s nothing wrong with that. We also enjoy it sometimes.

    We have a selection of casino apps available, offering the best online slots, that provide download links for iOS, Android, and Windows devices. So have a look around the site if you’re on the market for those.

    Is there a best time to play online slots

    Is there a best time to play online slots

    Some players believe that playing their favourite game at a specific time boosts their winning chances. It could have happened a few times, so it became a certainty. However, nothing could be further from the truth. There is no best time to play online slots, as they are games of chance, and the time you play them has zero influence on the outcome. So, you can enjoy the game you like any time of the day, and your winning potential will be exactly the same.
