Top Casino Software Providers

More casino providers appear regularly, as the world of online casinos is always on the hunt for new, exciting casino games. As online gaming grows in popularity, players get to enjoy new options related to their interests.

Game developers and gaming operators rose to the challenge. Microgaming was one of the first providers to take matters into their own hands, as they started to create high-end casino games of all shapes and sizes. Afterwards, many other companies like NetEnt, Play'n Go, Yggdrasil and Thunderkick followed suit.

Now, we have plenty of options with each provider specialising in a slightly different game offering. Some create games that are classic and easy to follow, and some of them create games that are exciting with new mechanics at every turn - some even going so far as to create a classic video game experience with gambling offerings!

With a healthy amount of competition amongst these software provider giants, they have managed to keep casino gaming exciting and dynamic, with new innovations appearing frequently.

On top of this, the switch to HTML5 has made games available on many operating systems meaning that there is no difficulty running them on a phone as well as a desktop computer, for example.

How Does Online Casino Software Work

How Does Online Casino Software Work? 

Before smartphones and tablets came into the picture, the only way to spin the reels of slot machine online was through your old trusty PC. Casino games on desktop computers tended to be made in Flash, which is no longer industry standard as it stopped games from being available on all types of device.

Eventually, as smartphones and tablets became commonplace, there were extra software issues that would make running Flash impossible on some devices. As eventually Flash support was discontinued, leapt into HTML5 - a relatively new way of building sites that was interactive, flexible, and far more useful for playing newer games and building better websites.

HTML5 is supported by all browsers and devices, and also allows for players to play their favourite slot machines on their mobile phones without skimping on quality. This way players can be assured that they can play their favourite games on the go and still enjoy the same experience as they would on desktop. Any good software provider keeps mobile-first casinos in mind when creating a concept for their new games.

Rating the Best Online Casino Software

What goes into an online slot game? One of the biggest factors in how a casino slot will play is volatility. Slots can vary between low and high volatility. Volatility is how often the slot symbols change, the variance in their appearance, and how wildly different each spin will be when playing. A lower volatility slot may vary less or have fewer events changing the spins, and a higher volatility slot will contain more changes on the reels. In addition to this, the slot's RNG has to be top-notch.

Low Volatility

Players who prefer to relax and gamble on slots purely for recreation and entertainment will find slot machines with a lower volatility more appealing. These games allow players to spend a small number of credits on a large number of spins. But of course, in turn, the payouts will be lower as well.

High Volatility

Ask a true high roller and they will recommend slot machines with high volatility. High volatility means that the hit rate of a slot will be rather low, but the payouts can be massive. This means that the player will have to bet a large sum of money in order to see a return on their balance. This style and mechanic of slot machines appeals to players who know what they are doing and are in it for the big prizes.

Software providers have been focusing on creating good looking and entertaining high roller slots to match the demand. Of course, if you like the old school you can always stick with classic high variance slot machines like Mega Moolah, Cleopatra, Da Vinci Diamonds and other classic slot machines.

Theme and Sound

The casino game should be fun to look at and listen to - after all, you are the one that's playing it! With casino games coming in so many different themes it makes it easy for players to pick something that appeals to them! Game developers generally pick a theme and soundtrack that go together and which is pleasing. Visual effects to make the game more exciting, as well as an encouraging soundtrack and sound effects all work together to improve the game experience.

What is RNG and How Does it Work

What is RNG and How Does it Work?

All spins in a slot game, for instance, are created using an RNG or Random number generator. This ensures that the game is run by chance and not set up to lose more often than win, for example. The RNG has to be tested by outside authorities, which ensures that the game is truly random and not weighted in any way.

Best Online Slot Bonuses

A casino game will often have extras coded into it. This can come in the form of extra rounds, we're lining up certain symbols will get you free spins for example, or even extra bonuses that come about due to game mechanics. For example, collecting a number of symbols as you play might trigger a bonus wheel spin which nets you an extra prize.

Best Mobile Casino Software

With the push to be mobile-ready, many casinos have to ensure they offer software that works well no matter which device it's being run on. Thankfully, most casinos use some of the top casino software developers to supply their games. As many casino games use HTML5, you can rest assured that your game will almost definitely run on any Android or iOS device.

What Makes The Best Online Casino Software? 

There are plenty of aspects that play into what makes casino software good. Is it trustworthy, has no bugs, and works well on any device? Or is it slow, from an unknown developer, and full of errors? Obviously, you'd want to look out for games that fit the first type - so here are a few pointers.

  • Ensure that the company that makes the games is licensed. You will be able to view their licences on their website or on the licensing authority's website;
  • Check that the casino software is provably fair and that it runs using an RNG in order to create a true chance when playing;
  • Check that you can run the game on both your mobile or tablet and your desktop - a good casino software will be built in HTML5 and run on any device

We recommend you also check out the exclusive online casinos page where you’ll find not only casinos powered by a variety of different software providers, but also with unique players’ features.

Note that the credibility of software companies reflects the overall quality of online casinos that work with these software providers. It is worth paying attention to the software providers of online casinos in order to feel safe playing for real money.

Casino Software FAQ

Is all online casino software the same?

No, many casino software operators will differ! They will have mechanics in common - for example all of them will run using an RNG to determine outcome, but otherwise may have different bonuses, designs, or bet amounts.

Can I play casino games on my mobile or tablet?

Yes, if the same is a modern and up-to-date one from a good provider. All of the providers that we suggest have switched to HTML5 from Flash, meaning their games will play on all mobiles and tablets as well as desktop computers, so long as the devices are up to date.

Can I play casino software for free and for real money!

It depends on the particular casino game you want to play, but many games will have a "test" or "play for fun" option available. When playing in this mode, you will not be playing for real money. To play for real money and make bets, you will need to register with the casino and deposit money into your account wallet.
