Mobile compatibility

One of the most important aspects of online gambling sites these days is the quality of their mobile offerings. More and more people are preferring to play their favorite games through their mobile device than sitting down at a desktop device. Therefore, casinos and casino game software developers are putting a lot more of a focus on the mobile selection of games.

You want to make sure that a given casino game software developer makes sure that it optimizes its leading titles for mobile devices. This means taking the time to make sure that they run smoothly on the smaller devices and that there is no negative impact on any of the game’s features. You also want to make sure that your specific mobile device is catered for through this online gaming operator. This could be a tablet or mobile device that relies on iOS or Android.

Downloadable online casino software vs in-browser (HTML5)

When it comes to online casinos, the space has changed a lot over the years. In the beginning, a lot of casino sites would require you to download their software in order to play online casino games. This meant that the application would have to run directly through your desktop. However, technology improved, there was a move towards offering games directly through browsers. This is now the preferred gameplay method for most online casino game players in the world today.

The same debate goes for mobile devices. Many online gambling sites have apps that you can download in order to get quick access to their library of games. These usually don’t take up much space and you can have access to all of the features with a click of a button. The gameplay quality will usually be better when you are using an app.

However, most online casinos will also offer a mobile website that allows you to play instant play games directly through the web browser on your mobile without having to download anything at all. This is preferred by many people who like to be able to play casino games without having too many apps. However, the gameplay quality and user experience might suffer slightly no matter what casino game software development company is supplying the games.

Live dealer game developers

One of the popular trends in recent years in the online casino space has been the explosion in the popularity of live dealer games. These titles provide the most immersive experience currently possible for online players. You will be able to access a live stream that is in HD-quality whereby you are looking at a dealer in a real-life casino or studio.

They will deal the cards or spin the wheel as you expect. Most of the time you can chat directly with the dealer or other players. The betting limits are usually wide-ranging and there will be many different variants available. Currently, Evolution Gaming is by far the best supplier of live dealer games in the world today.

They have live casino studios across the world, catering to all playing preferences and even different languages. This is the closest you are going to get to sit at a casino table in the flesh, while still being in the comfort of your own home. Most of these live dealer games will be standard iGaming table games, such as roulette, blackjack, video poker, craps, baccarat, blackjack, casino poker, and specialty game show titles.

Other casino game developers

As well as the list of the ten top casino game software developers in the world today, there are dozens of other great developers. Many of these narrowly missed out on a position in this list.

How often do casino game software providers release new games?

This will vary from provider to provider. Many of the cutting-edge bigger developers will have the ability to pump out multiple new titles every month as they have plenty of staff and the resources to do so. However, some prefer to focus on quality and only release a few every so often to casino operators. Most casino game software providers will also have one or two standout titles each year that they put the most effort into creating.

How many different casino game software companies will supply an online casino?

This depends on the specific situation. There are some casinos that will only have games from one or a handful of different casino game software providers. Then there will be those who work with dozens of different companies. Therefore, you will get a wide range of different scenarios depending on the online casinos that you are looking at.

What casino game software supplier has the best RTPs for their games?

There is no definitive answer to this question. Each developer in the gambling industry will have games with higher than normal RTPs and some that will be lower than normal. You will get a nice mix of everything no matter what developer you are dealing with.

Does every casino game software developer offer progressive jackpot games?

Progressive jackpot titles are a very popular gaming experience as they carry lucrative jackpots that can be one from relatively low stakes. Most of the major casino game software developers will have progressive jackpot titles, with only a handful having seven-figure options. A lot of the smaller developers will not offer any forms of major progressive jackpots.
