What Are Online Slots And How Do They Work?

Online casino games are a huge attraction to many gamblers across the world. And it’s safe to say that the online slot game genre often stands out as slots are the easiest and the most engaging ones among the vast selection of casino games.

With that said, most punters don’t know what makes up the basis of slot games simply because they are only interested in landing winning combos. However, knowing the math behind online slots can in fact help you increase the return of an online slot machine. But let’s don’t get ahead of ourselves and start with the basics, shall we?

What are Online Slots?

Simply put, online slots are the digital versions of levered slot machines you would find in all land-based casinos. Similar to real-life versions, spinning the reels on an online slot machine is all about landing winning combinations and reaping the rewards.

How do online slots work?

Slots, as you may already know, is a game of luck and there is no telling what the outcome might be before the reels stop for good. The developers achieve this “based-on luck” aspect by implementing a random number generator to their games. Simply put, these generators create a random sequence and each random number in slots corresponds to a different outcome.

In short, slots are purely based on luck. However, certain mechanics can improve your chances of landing wins. Let’s go through each of them so that you know what to look for while searching for a profitable online slot machine.

Return to Player Percentage (RTP)

Return to Player is a ratio that gives insights into the rewards you get as a player. This is the most common factor you can use to determine whether a slot will be profitable or not. Granted, slots rely on chance, but some slots offer a greater chance of winning over others. Therefore, it is always advisable to go for slots with higher RTPs, from 95% and above.


Also known as variance, volatility not only determines the chances of recording a win, but it also affects the prospects of winning big. Landing wins on a highly volatile slot is a rare thing indeed, however, once you land one, you can expect it to be huge. Lower volatility, in this case, simply means lower risk – lower rewards. You can also find some medium variance slots that try to keep a healthy balance between the frequency and the juiciness of your wins.


What contributes to the profitability of the game is highly reliant on the payout values of the symbols. That’s why you need to navigate to the paytable to have an idea of the payout structure of the game before you proceed to take action on a slot. The paytable gives you insight into whether a slot is profitable or not, so you must assess it before playing.

Bet Size

The bet size gives you insight into the required stake that is allowed in the game. Some slots allow a stake as low as 0.01 coins per spin. Depending on the kind of player you are, your preference could be determined by the bet size allowed in the slot. If you are a low-roller, you want to go for slots that offer you an opportunity to go to the barest minimum in terms of stake.


The special features in a slot help increase the profitability of a slot and increase your chances of winning. For example, some slots offer special features like free spins. With a feature like free spins, you tend to have an opportunity to spin at no cost, whilst exploiting the opportunity to win big regardless.

Before you settle for a slot, it is always advisable to check out the features they come equipped with. The more features they have available, the better your chance at winning.

How to Find Good Slots

Yes, taking all this in is challenging as there are many factors for you to consider if you want to improve your chances of landing wins. Luckily, you can get help from various gambling affiliates online instead of dealing with all these by yourself.
