What are online slots?

It may seem like the most straightforward thing in the world, but let’s talk about what makes an online slot machine spin.

The most popular are video slot games that come with 5 or more reels. Classic 3-reel slots still have a huge fan base, but video slots are the slots of today.

Video slots are found in online casinos and are some of the most popular casino games worldwide.

These slots are fun and rewarding, as they arrive with innovative bonus features that can boost your winnings, gamification elements and masterful design, visual and sound effects.


In their most basic shape, slots are games with sets if reels where you win a cash prize if the symbols line up like tic-tac-toe.

The structure has since evolved in many different sets of wheels, and it’s not uncommon that you find slots with an entirely different set of winning conditions, like cascading blocks or “candy crush” style.


The times of physical “one-armed bandits” is long past. These slots are driven by RNG’s, or “random number generators”. If you play slots from a respectable online slot provider, it will be random with no risk of unfair bias – It’s not rigged.

Slot Themes

To entice the modern casino player, slots need to be exciting, and we say why not! Find a game that suits your tastes to elevate your time at the wheels.

Mobile slots

Given the fact that technology keeps on evolving, it should come as no surprise for you to learn that online slots can be played across mobile devices. In fact, mobile slots are the centre of attention to slots players all over the globe.

That’s because slots software developers nowadays are creating the games to be fully optimized for mobile play, and accessible from both iOS and Android-powered devices.

This means that regardless of whether you have a Samsung or an iPhone, you can play at online slots sites for real money from wherever you are, be it the park, the office or the backyard of your home.

And, as you explore our list of South African slots sites, you will see that you may even find online casinos that are offering mobile apps you can download on your tablet or smartphone for even better and quicker access to your favourite games.

Anatomy of a Good Slot

From cherries to scatter symbols, online slot machines come in incredible varieties.

There’s no reason to waste time with the bottom of the barrel with the selection of slots presented in 2021, so let us show what you need to look out for in prime online slot machines.

  • Clear Payouts

    Within the information interface you will find the paytable, showing what the different symbols pay

  • Generous Paylines

    Most slots will increase the paylines with the coin value, make sure that the slot machine isn’t too stingy even on lower bets per spin.

  • Free Spins

    When you hit the home run, and trigger whatever free spins or bonus game the slot has to offer, you want it to pay. Play on online slots with generous and lengthy free spin modes.

  • Turbo Mode

    If you are a slot veteran, you might not be easily excited by the flashing lights. Online Slot Machines with a turbo, or “speed mode”, let’s you spin quicker to get to the point.

  • Return to Player

    Within the slots’ information panel you will find their RTP (return to player)

  • Mobile Friendly

    Every slot should be playable via mobile. All slots made from 2018 onwards are usually mobile responsive.

Slot Betting Tips

  • Be Smart About Free Spins

    If you receive free spins, use these.

  • Make consistent bets

    It’s tempting to blast your coin value when the symbols are in your favour, but remember: the odds don’t change from spin to spin.

  • Treat the MAX bet with caution

    The MAX bet button can be easily mispressed, don’t make this expensive mistake!

  • Check the RTP

    The RTP for a non progressive slot should range between 93-97%

  • Only Play with Good Reception

    Playing mobile slots is loads of fun, but if your bars are low, wait for a better time to play.

Online Slot Games

The slot games found in online casinos are developed by game provider companies like RTG.
The online casinos themselves do not develop or maintain any of the slot games, what difference you might find comes from the various promotions and casino bonuses they offer.

Some slot games are more popular than others, why?

Let me tell you sir! Just like we listed above, some slots stand out above the rest, and we like to highlight them.

Where can I play online slots for money?

Hundreds of online slots sites for real money exist out there, each offering special perks for you when you join them, and a massive collection of titles for you to choose from and play.

To get started with your online slots experience, you would have to choose a respected online casino and register an account with it.

After providing the casino with some basic info about yourself, you would have to specify a casino payment method you will use and the amount of your first deposit. And, after you’ve made your deposit, you can go on and start choosing the slot games to play.

You should know, however, that our team of experts with years of experience in reviewing online casino sites, have created a list of South African slots sites that you can explore.

There are over 200 online casinos that accept South African players, and our team has gone through each and every one of them to provide you with the most trusted choices.

Therefore, we at CaZAino have saved you some time and done the hard work for you, so that you can only skim through the list, choose the right site for you and start spinning the reels right away!

The basics of slots

The first-ever slot machine was designed way back in 1899 by Charles Fey, the “father of slots” in San Francisco, and was called the “Liberty Bell” machine.

It had 3 reels and players needed to land three matching symbols in order to get an automatic payout. The liberty bell symbol was the highest-paying one, hence its name.

The next milestone in slots history came in 1996 when the world-leading software developer WMS Industries Inc created the first-ever video slot called “Reel’ Em In”.

This was the first-ever game to feature a bonus round, too, with a different screen appearing after you trigger it.

And it was around the same time when the first slots were taken online, the late 90’s. Ever since, both video and classic slots have been evolving, becoming more innovative, unique and appealing to both new and existing players.

When Microgaming released the first online jackpot slot Cash Splash, slots reached brand new heights. To this day, online slots are still the most popular games across online casinos.

Is it legal to play slots in South Africa?

In South Africa, it is a bit of a grey zone whether you can actually play games of chance, while games of skill are completely forbidden.

Considering online slots are games of chance, you should know that you could play them because there are no records whatsoever of citizens being prosecuted in South Africa for playing slots.

The chance of actually getting caught playing online slots are close to zero, too, since you can play them from the commodity of your home and no one could ever see or know that you did it.

But, if you’re interested in finding out more about the legality of online gambling in South Africa, you should do a thorough search on the internet to investigate these things.

You will learn, though, that the grey area does exist, and that you can enjoy online slots whenever you want, since no one would bother trying to catch you doing so.

Winning potential

As mentioned, there are different types of online slots. Some are intended for the low-roller or the player that wants to place small bets, others for medium-rollers, and some for the high-rollers, the players who are willing to invest more in order to win more.

The thing is, your payout will depend on the amount of the bet you make. Say, the lowest paying symbol gives you a 10x the stake payout for a 5-of-a-kind combo and you’ve placed a small bet of ZAR1.75 per spin.

This means that by getting that winning combo, you will win ZAR17.5. If you’ve placed the max bet, for instance, of ZAR1,735, you would win ZAR17,351. As simple as that.

Naturally, different symbols give different payouts, and when special features get involved, as well, the max payout potential can get bigger and bigger.

Some bonus features give out random prizes, jackpot prizes or other perks to boost your winnings, so before you start playing a slot, make sure you go through its paytable page to find out more about the winning potential.

Wild and Scatter symbols

The majority, if not all, slots have a Wild symbol. This is like a joker, a bonus symbol that helps you combine symbols and create winning combos.

Its role is a substitute, as it fills the gap in the winning combo whenever you’re lacking a symbol to create one.

And, all slots that have bonus features in them also feature a Scatter. This is also a bonus symbol but has a different role. Its role is triggering bonus features, in most cases, triggering Free Spins.

You would need three to five Scatters in order to trigger a number of Free Spins in a slot, or another type of a bonus feature, or even the jackpot if the slot offers any.

Variations of the game

We’ve mentioned several variations of the game throughout the overview, but let’s recapitulate the main ones:

  •       Classic slots
  •       Video slots
  •       3D slots
  •       Mobile slots
  •       Progressive jackpot slots
  •       Megaways slots

These are the five variations or categories of the game you will probably find across South African casinos. Sure, operators may name them differently, but you should expect to find these slots variations on any site you join.

While we already discussed most of them, Megaways is the variation we haven’t, which needs special attention. Megaways slots are those that feature Big Time Gaming’s trademark Megaways mechanics.

They have become super popular among slots players, as they allow for up to 117,649 ways to win. Plus, they usually come with huge Multipliers and are playable with small bets, but their payout potential is massive.

The best part is, even though BTG invented Megaways, many other developers have acquired their license to use the mechanics in their slots, therefore, you’ll find hundreds of Megaways slots to try out and see what the buzz is all about.

Jackpot slots

As mentioned, Microgaming has created the very first jackpot slot in the online gambling industry, but many developers followed suit.

Today, you have plenty of progressive jackpot slots you can play for real money, which can deliver life-changing prizes.

Microgaming has created several of them, with Mega Moolah delivering a record win of €18,915,872 in 2018, but so have NetEnt, Playtech, and Yggdrasil, among others.

The following are some of the progressive jackpot slots that have delivered the most exciting prizes to players:

  •       Mega Moolah
  •       Mega Fortune
  •       Joker Millions
  •       Age of the Gods series
  •       Empire Fortune
  •       Divine Fortune
  •       Major Millions

How do these slots manage to give such massive prizes? Well, most of them are part of a progressive jackpot network, whose jackpot prize pools increase with each bet players all across the world make on the slots added to that network.

The more the players bet, the higher the jackpot prize goes. Then, all of a sudden, when least expected, a lucky player randomly hits the jackpot and grabs a seven or eight-figure payout. These slots are really something as they have created millionaires and multimillionaires overnight!

Play slots for real money vs. free

Now that you are equipped with the basic information on slots, it is time to put the knowledge into practice. That’s actually exactly what you need to do in order to become better at playing slots: practice.

You can practice playing slots by joining any online casino and loading the demo version of any slot. Slots have demo versions where you can play them for free, with fake money, credits.

Once you get ahold of the gameplay, and you understand how the slot works and gives out payouts, you can continue playing for real money.

Playing for real money is actually the only way to get to these massive payouts we’re mentioning all the time. If you make real money bets, meaning play at any slots casino with ZAR, you would get real money payouts that you can enjoy.

As you can see, with a bit of luck, you can even become a millionaire or multimillionaire if you decide to play Megaways or progressive jackpot slots.

Many new online casinos have opened in South Africa which accept South African rand and have dedicated Customer Support for South African players, so the choice is all yours.

Make sure you join the right one from the ones listed at CaZAino, practice playing for free first and then continue playing with real money bets to get to the most life-changing rewards! Enjoy!
